Durham Window Pros provides professional residential window installation in Durham, NC for residential and commercial properties across Durham County and the northern Triangle. A window is a machine with moving parts, and the test of an installation is not how it looks on the day. It is whether the sash still operates easily at every point of its travel two summers later.
That outcome is decided by shims. The unit's weight belongs on solid blocking beneath the jambs and on continuous support under the sill, placed so the frame cannot bow between bearing points. A tall double-hung carries real weight, and a sill unsupported in the middle takes a set nobody can shim out later.
Fasteners are not shims. Their job is to hold the frame where the blocking already put it. Where an installer uses screws to drag a frame into square, the jamb goes slightly hollow, the balances bind, and the latch no longer finds its keeper. On vinyl that arrives within a season.
So the opening gets checked before anything is ordered. Both diagonals, the sill for level, every jamb checked plumb, and jamb depth read at several heights rather than one. Durham clay moves houses, and an older foursquare in Trinity Park can be racked far enough that a unit bought to a stated width and height simply will not enter the hole.
Then the water detail, built although it will never be seen. A tray pitched outward beneath the unit, rear lip and both returns raised, with jamb pieces lapped across it and the head piece slipped behind the layer overhead. Water that gets behind the face has to be able to leave again.
Brick veneer changes that problem rather than removing it. On the 1990s stock across most of the county the drainage plane sits behind the brick, with a steel lintel over the opening and weeps at its base, so part of the detail is already in the wall and the rest has to work with it rather than against it.
Perimeter air sealing finishes the job and can undo it. Low-expansion product in the shim space, in a pass light enough that nothing moves as it cures, then a continuous interior seal. Each sash then gets run top to bottom once the foam has gone off, and again at handover. The second test is the one that matters.
There is no inspector here on most jobs. Statute lifts the building-permit requirement from this trade on a one-family house priced at or under forty thousand dollars, so the shim pattern and the flashing lap have exactly one reader. Our installations follow ASTM E2112 and we walk the sequence with you.
Our usual advice is to put the first money into the hole itself. A sill that has dropped, a jamb with nothing sound to screw into, a header that has sagged: that is carpentry, occasionally structural carpentry with a permit behind it, and a new unit set into any of it will bind whatever it cost.
Our 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 residential window installation
The difference between residential window installation that lasts and residential window installation 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, center 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.
