Durham Window Pros provides professional sliding patio doors in Durham, NC for residential and commercial properties across Durham County and the northern Triangle. A patio door is the largest moving assembly in most buildings and it fails in the least dramatic way: slowly, at the rollers and the sill, until it takes two hands and a shoulder. Most of what we are called about is repairable.
Take the repair route first, because it is cheaper and it works. Tandem rollers wear flat, the track develops a burr, the pile weatherstrip at the interlock compresses and stops sealing, and the sill track fills with grit. Replacing the rollers, dressing or capping the track and renewing the weatherstrip restores most doors to something close to new for a small fraction of a replacement.
When the frame itself is the problem, the sill is usually the reason. A patio door sill is a horizontal water detail with a moving part on top of it, and it needs a sill pan with end dams and a back leg beneath it. On a converted building with a masonry sill or a balcony threshold, water that gets past the sill has nowhere sensible to go and works into the structure below.
So on a masonry opening we set the door on a formed or fabricated pan that turns up at both ends and at the back, seal the pan to the substrate, and leave the front edge open so the pan drains outward. It adds an hour to the day. It is the difference between a door that leaks in year eight and one that does not.
Sizing in Durham's converted buildings is its own exercise. Loft and warehouse balcony openings were rarely built to residential door dimensions, so a stock two-panel unit often leaves a foot of infill above or beside it. We prefer to fill the opening properly with a three-panel configuration or a door plus a fixed transom on the same frame, rather than framing down a masonry opening to suit a catalogue.
Glass is a code item here, not a preference. Glazing in a sliding door and in any fixed panel of the same assembly is a hazardous location and must be safety glazing. That means tempered or laminated in every panel, always, and you should see it on the etch in the corner of each lite before we leave. Laminated is worth considering on a ground-floor door for the entry resistance.
Hardware deserves ten seconds of attention. A single hook latch into a strike screwed to the jamb is the weakest part of most patio doors. A multipoint latch that engages the head and sill as well as the jamb costs a little more, makes the door pull tighter against its weatherstrip, and removes the most common way these doors are opened by somebody who should not.
If the sliding action is the only complaint and the glass and frame are sound, we will quote the rollers and go. That job is a couple of hundred dollars and takes an hour, and we would rather do a hundred of those a year than talk one homeowner into a door they did not need.
Our licensed and insured team brings the right materials and equipment to every job — polyamide strut thermal breaks, steel lintels and relieving angles, through-wall flashing and weep tubes, pultruded composite sash sections, warm-edge stainless spacers, laminated acoustic interlayers — and backs the work with a written workmanship warranty. We serve Durham and nearby communities including Chapel Hill, Carrboro, Hillsborough, Efland.

Materials, equipment and how we do sliding patio doors
The difference between sliding patio doors that lasts and sliding patio doors that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with polyamide strut thermal breaks, steel lintels and relieving angles, through-wall flashing and weep tubes, pultruded composite sash sections, 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 Durham 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 Durham County and the northern Triangle means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Durham Chooses Durham Window Pros
- ✓We identify the wall before we name a product. A punched opening in a brick bearing wall takes a different unit, a different anchor and a different water detail than a stud wall, and the quote says which one you have.
- ✓North Carolina exempts window and door replacement from the building permit below forty thousand dollars, which means no inspector ever looks at it. We put the flashing sequence and the anchor spacing in the written proposal so there is a record.
- ✓Openings are measured at head, centre and sill and checked on both diagonals. In converted mill and warehouse buildings the difference across one opening is routinely more than the tolerance a stock unit allows for.
- ✓We quote laminated glass for noise and forced entry rather than impact packages for a debris region Durham is not in. If you want the acoustic benefit we will price the interlayer; we will not price a hazard you do not have.
