Window Work We Do in Charleston

Full Window Replacement
A whole house of windows on the peninsula is not one job on one calendar. It is a scope divided by what the street can see, and the part the street can see moves at the pace of a board with a monthly agenda.

Residential Window Installation
Two crews can set the identical unit in the identical opening and hand back two different buildings. The variable is almost never the window.

Commercial Window Installation
Commercial glazing is a different license, a different board and a different order of operations from residential work, and treating it as a bigger version of a house is how downtown storefront projects end up months late and thousands over. The license first.

Energy-Efficient Window Installation
Charleston County hands you a one-page form before it will permit a window job, and that form is the plainest statement of what this city requires of your glass. Four things go on it.

Vinyl Window Replacement
This is the page where we talk you out of the product, across half of this city. The BAR's adopted window policy contains four words with no wriggle room: no vinyl or vinyl components.

Wood Window Replacement
This is the frame the districts are written around, and the vocabulary matters more than the brand. The policy distinguishes three grid types and treats them as different products.

Aluminum Window Replacement
This is the one market in our fleet where aluminum is a serious answer rather than a leftover. Hot humid air makes frame conduction a minor penalty, while wind, salt and 150 mile an hour design criteria make frame strength a real argument.

Bay and Bow Windows
A bay or a bow is not a window in any meaningful sense. It is a miniature addition that happens to be glazed, and that governs how the job runs here, from the review path to the flashing detail to whether we build it at all.

Broken Window Glass Installation
One cracked light in a sash that still runs is a glazier's afternoon, and that is the call worth making. This page is for the other thing: glass as part of a larger job, where the opening or the sash is already apart.

Casement Window Replacement
Casements seal better than anything else you can buy. The sash pulls into a compression gasket all the way round, so air infiltration numbers are the best in the catalog.

Custom Window Installation
Custom work on the peninsula has to satisfy two authorities that rarely agree. One cares what the window looks like from the street.

Double-Pane Window Replacement
Double pane is the baseline, not the upgrade. Nearly every replacement window quoted in the Lowcountry is already an insulated unit, so asking for double pane usually means asking for an ordinary modern window.

Egress Windows
Egress is arithmetic, not opinion, and it is the one part of a window quote nobody gets to negotiate. Bedrooms have to carry an opening a firefighter can come through and an occupant can get out of, and those figures derail more replacement jobs here than anything else.

Fiberglass Window Replacement
Fiberglass frames are pulled, not welded. Glass strands and resin are drawn through a heated die as a continuous lineal, then cut and joined, which is why the material behaves so differently from a plastic extrusion in this climate.

French Doors
French doors belong to Charleston in a way they do not to most American cities, because the building type demands them. The single house turns its narrow end to the street and runs a piazza down its long flank, and the rooms open onto it through glazed doors.

Impact Window Installation
This is the page where the two authorities in this city collide, and where our recommendation departs furthest from what you will be told elsewhere. The short version: the code requires the opening to be protected.

Low-E Glass Window Installation
Low-E is a coating, not a tint. A metallic film thinner than anything you can see or feel, bonded to the glass while the unit is built.

Multifamily & HOA Window Replacement
Windows on a building with an owners' association are not a homeowner's purchase. The person who notices the draft, the body that authorizes the work and the account the money leaves are usually three different things, and the order they move in sets your calendar.

Office & Commercial Glazing
Office glazing above a shop differs from storefront work in one respect that governs everything else. There is no sidewalk to close, no cart traffic, and someone is sitting on the other side of the glass at a desk, probably on a call.

Retrofit Windows
Charleston asks a replacement window to do two things at once. The permit counter wants a wind-borne debris specification, because the city's design wind speed puts every address inside the debris region.

Sliding Window Door Replacement
Sliders are the honest workhorse of the elevations nobody photographs. They are cheap, they are wide, they open without swing clearance, and there is almost nowhere in a Charleston historic district where one is going on a face the public can see.

Soundproof Window Installation
Nothing sold as a soundproof window is soundproof. What a good one does is reduce what reaches a room, and on an older house here the glass is rarely the part holding you back.

Storefront Window Installation
On King Street the building line and the sidewalk line are nearly the same line. That one fact governs more storefront decisions than the glass does, because almost everything in the system either sits over public ground or opens onto it.

Triple-Pane Window Installation
Here is the short answer for a hot and humid coast. No.

Open any service to see exactly what is included before you call.
Full Window Replacement
A whole house of windows on the peninsula is not one job on one calendar. It is a scope divided by what the street can see, and the part the street can see moves at the pace of a board with a monthly agenda. So we scope a Charleston house as three jobs rather than one.
- whole house window replacement
- replace all the windows in a house
- window replacement project schedule
- phased window replacement by elevation
- whole house window order lead time
- peninsula window replacement sequencing
- architectural review window schedule
- window replacement crew day count
Residential Window Installation
Two crews can set the identical unit in the identical opening and hand back two different buildings. The variable is almost never the window. It is where water goes after it gets past the joint, and whether anyone planned for that at all.
- window installation Lowcountry
- sill pan and head flashing on lap siding
- wind driven rain window leak Charleston
- window install over a vented crawlspace
- stainless window fasteners harbor elevation
- rotted window sill repair before replacement
- window installation inspection Charleston
- perimeter air sealing around a window frame
Commercial Window Installation
Commercial glazing is a different license, a different board and a different order of operations from residential work, and treating it as a bigger version of a house is how downtown storefront projects end up months late and thousands over. The license first. In South Carolina, Glass and Glazing is a general contractor classification under Section 40-11-410, and it is the classification that names curtain wall systems, mall fronts and architectural window systems.
- storefront glass replacement
- curtain wall glazing
- aluminum storefront framing
- all glass entrance doors
- tempered storefront lites
- commercial door closers and pivots
- structural silicone reglazing
- storefront King Street
- office building window replacement
- restaurant glass replacement

- thermally broken storefront
- BAR large commercial review
- glass and glazing contractor license
Energy-Efficient Window Installation
Charleston County hands you a one-page form before it will permit a window job, and that form is the plainest statement of what this city requires of your glass. Four things go on it. Two concern storms.
- charleston window u-factor shgc permit
- charleston county window permit requirements
- 2009 iecc replacement fenestration south carolina
- energy efficient replacement windows charleston county
- historic district window efficiency charleston
Vinyl Window Replacement
This is the page where we talk you out of the product, across half of this city. The BAR's adopted window policy contains four words with no wriggle room: no vinyl or vinyl components. That applies in every district it governs, on every elevation visible from a public right-of-way.
- vinyl replacement windows
- welded vinyl frame
- vinyl double hung windows
- budget window replacement
- composite window frames
- vinyl sliders
- rental property windows
- subdivision window replacement
- vinyl vs fiberglass windows
- reinforced vinyl meeting rail
- white and almond vinyl frames
- vinyl window warranty
- Berkeley County window replacement
Wood Window Replacement
This is the frame the districts are written around, and the vocabulary matters more than the brand. The policy distinguishes three grid types and treats them as different products. Getting the wrong one specified is the single most common reason a window submission comes back.
- aluminum clad wood windows
- true divided lite windows
- simulated divided lite windows
- authentic divided lite
- muntin profile matching
- historic district window replacement
- putty glazed sash
- wood window restoration
- custom sash to match existing
- mahogany and cypress sash
- clad wood patio door
- BAR approved windows
- match existing grid pattern
- peninsula window replacement
Aluminum Window Replacement
This is the one market in our fleet where aluminum is a serious answer rather than a leftover. Hot humid air makes frame conduction a minor penalty, while wind, salt and 150 mile an hour design criteria make frame strength a real argument. Start with what is in the walls.
- aluminum slider replacement charleston county
- 1980s aluminum window replacement mount pleasant sc
- coastal aluminum window installation charleston
- aluminum window replacement summerville sc
Bay and Bow Windows
A bay or a bow is not a window in any meaningful sense. It is a miniature addition that happens to be glazed, and that governs how the job runs here, from the review path to the flashing detail to whether we build it at all. On a reviewed elevation the answer is usually no.
- bow window installation
- bay window seat
- bay window roof and flashing
- cable support bay window
- garden window
- bay window headboard
- projecting window addition
- bow window five lite
- bay window insulation
- copper bay window roof
- bay window structural support
- rear elevation bay window
- bay window sagging repair
Broken Window Glass Installation
One cracked light in a sash that still runs is a glazier's afternoon, and that is the call worth making. This page is for the other thing: glass as part of a larger job, where the opening or the sash is already apart. Three pieces of work sit under that.
- sash reglazing Charleston peninsula
- glass cut to a measured sash rebate
- safety glazing upgrade during renovation
- laminated glass for a historic sash
- glass for a reframed window opening
- putty glazed true divided light repair
- tempered glass ordered to finished size
- salvaged cylinder glass in an upper sash
Casement Window Replacement
Casements seal better than anything else you can buy. The sash pulls into a compression gasket all the way round, so air infiltration numbers are the best in the catalog. That is the case for them, and outside the historic districts it is a strong one.
- awning windows
- crank operator replacement
- casement hinge replacement
- steel casement windows
- multipoint lock casement
- egress casement window
- awning window over kitchen sink
- casement vs double hung
- hopper windows
- stainless casement hardware
- casement window air seal
- changing window operation type
- coastal casement hardware corrosion
Custom Window Installation
Custom work on the peninsula has to satisfy two authorities that rarely agree. One cares what the window looks like from the street. The other cares what it does at 150 miles an hour.
- custom window replacement charleston county
- true divided light window replacement charleston
- historic window replacement charleston peninsula
- oversized fixed glass installation mount pleasant sc
- custom window templating charleston county
Double-Pane Window Replacement
Double pane is the baseline, not the upgrade. Nearly every replacement window quoted in the Lowcountry is already an insulated unit, so asking for double pane usually means asking for an ordinary modern window. The useful conversation is about the seal around it.
- double pane window replacement charleston
- insulated glass unit replacement charleston county
- failed window seal mount pleasant sc
- sealed unit replacement lowcountry
- foggy double pane windows charleston
- warm edge spacer windows south carolina
Egress Windows
Egress is arithmetic, not opinion, and it is the one part of a window quote nobody gets to negotiate. Bedrooms have to carry an opening a firefighter can come through and an occupant can get out of, and those figures derail more replacement jobs here than anything else. What gets measured is net clear opening: the void left once the sash is thrown wide, not the frame dimension printed on the order.
- emergency escape opening
- net clear opening 5.7 square feet
- sill height 44 inches
- bedroom window code
- basement egress window
- raised foundation egress
- attic conversion egress
- egress window well
- casement for egress
- R310 requirements
- enlarging a window opening
- converted attic bedroom
- rental inspection window
- window opening control device
Fiberglass Window Replacement
Fiberglass frames are pulled, not welded. Glass strands and resin are drawn through a heated die as a continuous lineal, then cut and joined, which is why the material behaves so differently from a plastic extrusion in this climate. The property worth paying for is dimensional stability.
- windows fiberglass charleston county
- pultruded fiberglass frame installation lowcountry
- fiberglass windows mount pleasant sc
- large span window replacement charleston
- fiberglass window installers summerville sc
- coastal window frame specification charleston county
French Doors
French doors belong to Charleston in a way they do not to most American cities, because the building type demands them. The single house turns its narrow end to the street and runs a piazza down its long flank, and the rooms open onto it through glazed doors. That piazza is not a porch bolted on for looks.
- piazza doors
- in swing vs out swing french doors
- double french door replacement
- astragal and flush bolts
- multipoint lock french doors
- french door threshold
- true divided lite french doors
- interior french doors
- jib window doors
- single house piazza
- french door weatherstripping
- french door hinge sag
- wood french doors coastal
Impact Window Installation
This is the page where the two authorities in this city collide, and where our recommendation departs furthest from what you will be told elsewhere. The short version: the code requires the opening to be protected. It does not require you to buy an impact window.
- opening protection wind code
- large missile test ASTM E1996
- 150 mph design wind speed
- laminated impact glass
- safety glazing film
- wind zone 3 South Carolina
- hurricane protection historic homes
- design pressure rating windows
- impact rated entry doors
Low-E Glass Window Installation
Low-E is a coating, not a tint. A metallic film thinner than anything you can see or feel, bonded to the glass while the unit is built. On a peninsula address that invisibility turns out to be its most useful property.
- solar control glass replacement charleston county
- coated insulated glass units lowcountry
- glass package specification mount pleasant sc
- window schedule glass makeup charleston
- replacement glass for cypress sash charleston
- summerville sc low-e window installation
Multifamily & HOA Window Replacement
Windows on a building with an owners' association are not a homeowner's purchase. The person who notices the draft, the body that authorizes the work and the account the money leaves are usually three different things, and the order they move in sets your calendar. Start with the governing documents rather than with a product.
- HOA window replacement
- condominium window replacement
- horizontal property regime window project
- association board window schedule
- phased window replacement by building
- common element window responsibility
- occupied unit window installation
- property manager window survey
- apartment building window replacement
Office & Commercial Glazing
Office glazing above a shop differs from storefront work in one respect that governs everything else. There is no sidewalk to close, no cart traffic, and someone is sitting on the other side of the glass at a desk, probably on a call. That person is the constraint.
- commercial office window glazing
- interior glass partitions
- office front glass installation
- conference room glass wall
- demountable glass partition
- upper floor office glazing
- borrowed light interior glazing
- tenant suite glass replacement
Retrofit Windows
Charleston asks a replacement window to do two things at once. The permit counter wants a wind-borne debris specification, because the city's design wind speed puts every address inside the debris region. The Board of Architectural Review wants a window that matches what is already there.
- retrofit vs full frame windows charleston
- historic district window replacement charleston
- pocket replacement windows charleston county
- board of architectural review windows charleston
Sliding Window Door Replacement
Sliders are the honest workhorse of the elevations nobody photographs. They are cheap, they are wide, they open without swing clearance, and there is almost nowhere in a Charleston historic district where one is going on a face the public can see. That is not a criticism of the product.
- gliding window replacement
- horizontal slider windows
- sliding window rollers
- slider window track repair
- rear elevation windows
- aluminum slider replacement
- vinyl sliding windows
- wide opening slider
- egress sliding window
- sliding window weep holes
- garage and workshop windows
- 1970s aluminum sliders
- low profile window sightlines
Soundproof Window Installation
Nothing sold as a soundproof window is soundproof. What a good one does is reduce what reaches a room, and on an older house here the glass is rarely the part holding you back. Begin with the honest accounting.
- sound reducing window installation
- acoustic laminated glass windows
- noise reduction windows
- quiet bedroom window replacement
- laminated acoustic glazing
- interior acoustic storm panel
- street noise window upgrade
- unequal pane thickness glazing
Storefront Window Installation
On King Street the building line and the sidewalk line are nearly the same line. That one fact governs more storefront decisions than the glass does, because almost everything in the system either sits over public ground or opens onto it. Start with where the frame plane falls.
- aluminum storefront system
- recessed storefront entry
- storefront work over a public sidewalk
- display window glass thickness
- laminated glass for a shop front
- storefront bulkhead height
- shop front glazing
- storefront lite size and weight
Triple-Pane Window Installation
Here is the short answer for a hot and humid coast. No. We will install triple glazing if a client insists on it, and we will tell you first why the money is in the wrong place.
- triple pane window installation charleston
- triple glazed windows mount pleasant sc
- triple pane vs impact windows charleston
- triple pane window installers summerville sc
- hot humid climate window glazing charleston
- triple pane windows goose creek sc

What Charleston property owners ask us
Which window services does Charleston Window Pros handle?
Everything listed on this page, residential and commercial, across Charleston and the South Carolina Lowcountry. Work is done by our own crews rather than handed to whoever is cheapest that week, which is the only way the workmanship warranty means anything.
Can I combine more than one service in a single job?
Yes, and it is usually cheaper. Bundling window work into one mobilization saves setup, disposal and travel, and it means one crew, one schedule and one written free estimate instead of three contractors blaming each other.
Do you give free estimates for every service?
Every one. We come out, measure, look at the real condition of the work area, and put an itemized free estimate in writing with materials and scope spelled out. No charge, no deposit, and no obligation to book.
What Charleston Customers Say
We had two quotes for the whole house at one number and no mention of review. These guys came out, walked the lane behind us, and showed us that four openings were visible from it and eleven were not. The eleven got a clad unit, the four got repaired sash and a storm panel. Total came in under both of the other quotes.
Straightforward job, no review, no drama. They measured every opening rather than assuming the builder used one size, which turned out to matter on the two upstairs bedrooms. Egress numbers were written on the quote. Installed in a day and a half and cleaned up the mulch bed afterwards.
Called about condensation between the panes on eight windows and expected to be sold a whole-house replacement. They swapped the sealed units in the existing frames and replaced two failed balances. About a quarter of what I had braced for. They also told me which two frames really are near the end and to budget for those.
Salt eats hardware out here and every previous installer ignored it. This crew specified the rollers and fasteners as a separate line item and explained why the ocean side and the marsh side of the house were getting different parts. Sliders still run with one finger after two seasons.
