Rock Hill Window Replacement provides professional double-hung windows in Rock Hill, SC for residential and commercial properties across the South Carolina side of the Charlotte metro. The double hung is the default sash in Rock Hill, from the mill houses near Highland Park to the ranch belt off Ebenezer Road. It is also the sash where a replacement quietly costs you egress.
Code wants 5.7 square feet of net clear opening on an escape window, or 5.0 where the opening is at grade floor or below. Clear height of 24 inches minimum. Clear width of 20 inches minimum. Sill at 44 inches above the floor or lower. Those numbers are the same in the 2015 IRC that North Carolina still builds to and in the 2021 edition South Carolina adopted.
That last point matters because people expect the border to change everything. On egress geometry it changes nothing. What changes is who has to be licensed to do the work and who reviews the permit, not how big the hole has to be. Two thirds of the houses we quote in this county have them.
The double-hung problem is that only the lower sash counts. Your net clear opening is roughly half the glass area, minus the frame you add on a pocket installation. A bedroom window that measured 5.9 square feet in the original wood frame can come back at 5.2 after an insert goes in, and the room no longer complies. Tilt-latch hardware eats another quarter inch off the clear height on some lines.
So we measure the existing net clear opening, model the insert loss, and tell you before the order goes in. Sometimes the answer is a full-frame installation instead of a pocket. Sometimes it is a casement in that one opening and double hungs everywhere else. Sometimes it is enlarging the rough opening, which is a different permit conversation entirely. We would rather lose a sale than hand you a bedroom that no longer meets R310.
On the hardware side, constant-force coil balances have largely replaced block-and-tackle in this price range and they hold a heavy sash better over time. Tilt latches are the part that breaks. Ask whether the manufacturer still stocks them for a ten-year-old line before you commit to a brand. Sash locks and balance shoes are the other two parts worth asking about.
Rock Hill's older stock brings a second issue. Original double hungs with sash weights ran in a pocket cavity that is usually uninsulated and often open to the wall. A pocket replacement seals the sash and leaves the cavity alone. A full-frame replacement lets us fill it. On a 1930s house that cavity is frequently the single largest air leak in the wall.
Our position, plainly: pocket installations are the right call when the existing frame is sound, square and not hiding rot, and when egress still clears with room to spare. Everywhere else the full-frame job is the honest recommendation even though it costs more and takes longer. We show you the measurement either way, so the decision is yours and not ours.
Our licensed and insured team brings the right materials and equipment to every job — statutory 2009 IECC fenestration ceilings, NFRC whole-unit U-factor and SHGC labelling, warm-edge stainless and structural-foam spacers, condensation-resistance-rated aluminum thermal breaks, AAMA 2605 fluoropolymer exterior finishes, ASTM F2090 window opening control devices — and backs the work with a written workmanship warranty. We serve Rock Hill and nearby communities including Fort Mill, Tega Cay, Lake Wylie, York.

Materials, equipment and how we do double-hung windows
The difference between double-hung windows that lasts and double-hung windows that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with statutory 2009 IECC fenestration ceilings, NFRC whole-unit U-factor and SHGC labelling, warm-edge stainless and structural-foam spacers, condensation-resistance-rated aluminum thermal breaks, 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 Rock Hill 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 side of the Charlotte metro means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
