Charleston Window Pros provides professional egress windows for bedrooms in Charleston, SC for residential and commercial properties across the South Carolina Lowcountry. 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. It has to reach 5.7 square feet of area. Separately, the clear height cannot drop under 24 inches, the clear width cannot drop under 20, and the sill has to sit 44 inches or lower off the floor. Four conditions, all at once.
Here is the trap. Replacing a compliant window with a same-size unit can make the room non-compliant, because the new frame is thicker and the new sash steals clear opening from the hole. An insert unit into an existing frame is the worst offender. We measure the existing net clear opening and the proposed one and put both numbers on the estimate.
Charleston makes this harder than most places because of how its houses sit. The single house and its cousins are raised, sometimes a full story, over a brick or masonry base. That puts the ground-floor sill high and the finished floor higher still, which is fine for the 44-inch rule but adds a long drop on the outside of the opening. Worth knowing before you decide which room a child sleeps in.
Enlarging an opening is where the review comes back in. Cutting a masonry or clapboard wall to make an opening bigger changes the proportion of the elevation, and on any face visible from a public right-of-way in the districts that is a Board matter, not a paperwork exercise. It is also structural, because a wider opening needs a longer header.
So on a reviewed elevation our advice is nearly always to solve egress somewhere else. Put the escape opening on a rear or side wall the right-of-way cannot see, or change which room is being used for sleeping. Both are cheaper and both are approvable, and neither one asks a preservation board to accept an opening that was never there.
Attic and dependency conversions are the other common trigger. Charleston has a lot of upper floors and outbuildings that have quietly become bedrooms, and a dormer or gable window that looks generous frequently fails the height or width minimum on its own even when the area passes. Both minimums have to be met at the same time as the area, and a wide short dormer window fails on height no matter how large it looks.
If you are converting, call before the drywall goes up. Framing an opening correctly at the start costs a few hundred dollars. Cutting one into a finished, insulated, plastered wall on a raised masonry base, and then defending it at a hearing, costs a great deal more than that. It is the cheapest phone call you will make on the whole project.

Materials, equipment and how we do egress windows for bedrooms
The difference between egress windows for bedrooms that lasts and egress windows for bedrooms that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with true divided lites bedded in glazing putty, simulated divided lite bars with a shadow spacer between panes, authentic divided lite fused-pane sash, aluminum-clad and fiberglass-clad wood frames, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Charleston job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of window work in the South Carolina Lowcountry means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

- ✓No vinyl quoted where the policy forbids it, and no relabelling a vinyl-cored product as composite to try to slip it past staff
