Durham Window Pros provides professional custom window installation in Durham, NC for residential and commercial properties across Durham County and the northern Triangle. The median Durham County housing unit was built around 1993, so the custom work is concentrated in a small part of the city. Trinity Park, Morehead Hill and the mill villages, where nothing is square and the sash patterns matter.
In those houses custom rarely means a shape. It means a size that no longer exists and a divided-light pattern that has to be reproduced: muntin width, muntin profile, and the number of lites per sash. Get the pattern wrong and the elevation reads wrong from the sidewalk, which is the whole objection.
Eight local historic districts sit inside Durham, and inside them any exterior change needs a certificate of appropriateness, visible from the street or not, permit or not. That review sets your calendar, and it sits before the order rather than beside it.
Templating an old opening is slower than measuring a new one. We pattern the head, record the diagonal and the out-of-square, read the jamb depth at several points and note where the frame has moved. A foursquare opening can be out enough that a unit ordered to a width and a height will not go in at all.
North Carolina is running an old code on purpose, and on a made-to-order unit the edition matters. The 2018 residential and energy codes, both built on the 2015 International Codes, are still listed as currently effective by the State Fire Marshal's office.
A 2024 series has been approved but its start date was reset in a March 2025 letter, so confirm which edition your inspector is working to before anything is cut. We put the answer on the order paperwork rather than in somebody's memory.
A custom shape also has more joints than a rectangle, and every one is a decision. On an arch the head flashing has to follow a curve and the sealant joint has to be designed rather than run, which is why we draw the head detail and the sill pan before the unit is ordered.
Permits follow state law here. Below a project cost of forty thousand dollars no building permit is needed for a window or door replacement, and above it one is. The city and county building and safety department at City Hall Plaza is where it gets filed, and a general contractor license becomes mandatory at the same number.
Two things about custom that nobody volunteers. The deposit is spent when the order drops, because a sash cut to your pattern fits one house. And there is no shelf stock behind it, so a failed unit years later is another made-to-order piece on another lead time.
When not to order custom: on anything built since the 1990s, which is most of the county, an odd-looking opening is usually a stock size and the fix is a stop extension. In a historic district the honest answer is sometimes repair of the original sash rather than a reproduction of it.
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 custom window installation
The difference between custom window installation that lasts and custom 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.
