★★★★★ 600+ Verified Reviews ★★★★★ · a month ago"After I made an appointment I decided I was going to try and do it myself. Michael FaceTimed me, walked me through what to do, then call back if I still needed him. An hour later I called him and he was at my house in 35 minutes. Some of the best service I've ever received from a contractor. He finished in two hours and went above and beyond. The same-day service was incredible. Absolute professionals."
★★★★★ · a year ago"After a couple of hiccups with getting our repair done by someone else, our technician Richard showed up on time, actually half an hour earlier than the appointment time. He was very polite and got the job done in the time he told us it would take. Our glass door now glides smoothly and is able to lock again. I highly recommend Richard, he represented his company very well. I will definitely consider using them in the future!"
★★★★★ · 9 months ago"David, thank you so much for taking the time to explain everything to us. He was so patient, and I appreciate him doing a clean and awesome job. He was respectful of my home and cleaned up after the work was complete. Now my door slides like new, quiet, and smooth. Again, thank you David."

Practical advice for maintaining your sliding doors in Charleston County's local conditions.
Zinc-plated rollers, plated handles, and plain steel fasteners are what fail first in Charleston County. When you replace hardware, pay the small difference for 316 stainless or marine-grade parts, and avoid mixing metals in the same assembly, because dissimilar metals corrode against each other faster in salt air than either does alone.
Check the weatherstripping and caulking around your doors and windows at least twice a year, once before the rainy season and once after. Early detection of seal failures prevents costly water damage.
Before hurricane season, have the seals, locks, and track drainage on your Charleston County doors professionally inspected. A panel that seals under normal rain can still take water under storm pressure, and that is a cheap thing to find out in May rather than in September.

We provide leaking door & window repair across all of Charleston County, including:
The most common causes are worn or damaged weatherstripping, failed caulking around frames, improper installation, cracked or shifting frames, broken glass seals, and clogged weep holes that prevent proper drainage. Age, UV exposure, and climate conditions accelerate the breakdown of sealing materials.
Signs of a leak include visible water on the floor or sill after rain, moisture stains or discoloration around the frame, peeling paint near the door or window, musty odors indicating mold growth, and condensation or fogging between double-pane glass. Even small amounts of moisture should be investigated promptly.
In most cases, yes. The majority of leaks are caused by failed seals, worn weatherstripping, or deteriorated caulking, all of which can be repaired without replacing the entire unit. If the frame or glass is severely damaged, we will recommend the most cost-effective solution, whether that is a targeted repair or full replacement.
Costs depend on the source and severity of the leak. Simple weatherstripping or caulking repairs are at a lower price point, while frame repairs, glass seal replacements, or multi-point leak issues cost more. We provide a flat-rate quote after our assessment so you know the exact cost before work begins.
Absolutely. The same gaps that let water in also allow conditioned air to escape, raising your energy bills. Sealing these gaps with new weatherstripping, caulking, and proper frame adjustment restores your home's thermal envelope, often resulting in noticeable energy savings.
Condensation between panes means the insulated glass seal has failed, allowing moisture into the space between the glass layers. This reduces insulation and obscures your view. The affected glass unit needs to be replaced, we can replace just the glass without replacing the entire window frame in most cases.
It depends on where the opening sits. Most of coastal Charleston County falls in the wind-borne debris region under the South Carolina Building Code, and there a glazed opening within 30 feet of grade has to be impact rated or protected by an approved shutter. Further inland the design wind speed drops and impact glass becomes an upgrade rather than a requirement. I check the address against the exposure before I quote so nobody pays for a rating they do not need, or fails an inspection because they skipped one.
We run same-day service across Charleston County and all of Charleston County when route capacity allows. My technicians are based locally and can usually reach anywhere in Charleston County within a few hours of your call, and once we are on site most repairs take roughly 2 hours.
