Durham Window Pros provides professional aluminum window replacement in Durham, NC for residential and commercial properties across Durham County and the northern Triangle. Ranch houses from the 1960s and 1970s across northern Durham County are full of wide aluminum sliders. If that is what you have, this page is about identifying it rather than selling you more of it.
Unbroken aluminum is a continuous metal path from the heated room to the outside air with your glass hung in the middle. That is thermal bridging, and it is the reason the material lost residential work once energy codes began rating whole units instead of glass. Nothing about the coating on the glass changes what the metal is doing.
People assume a mild winter makes this academic. It does not. The interior metal face of a non-broken frame will run cold enough in a Durham January to condense and drip, which is exactly the complaint tenants in non-broken storefront report as a roof leak. Water on the metal rather than between the panes is the diagnostic.
A thermally broken frame holds the inner and outer profiles apart with an insulating member that carries the load between them. It is made either by crimping a polyamide strut into both halves or by pouring resin and cutting the metal bridge away afterward. A dark anodized finish is not a thermal break.
Nobody can tell you from the frame material whether a unit complies. The energy code in force is still the 2018 edition, built on the 2015 International Codes and listed as currently effective by the State Fire Marshal's office, and compliance is read from the certified whole-unit rating. Thermally broken aluminum often meets it.
A great many houses here hold their windows in brick veneer, and pulling an aluminum frame out means disturbing the opening, the head detail and the sealant joint around it. That is why a sound, square aluminum master is often a better insert host than a demolition candidate, which our retrofit page argues properly.
Here is the local consequence. State law exempts window and door replacement from a permit at or under forty thousand dollars of project cost, so on most houses no inspector looks at the work and no label gets checked. The certified sticker and the order file are the only record you will ever hold.
Aluminum still wins some openings. The ground floor of a commercial building takes a center-set aluminum system because nothing else holds that span, and on a house a wide fixed lite or a dark finish on a long unit is a real case for metal. Thermally broken storefront costs more and is the right buy in an occupied building here.
When not to buy: a wide 1960s slider that is square and still draining usually needs rollers, a track and weatherstrip rather than a new frame. And if you are replacing residential windows in existing openings, specify a broken frame or a different material; unbroken aluminum is not worth buying at a discount. Ask for the section drawing before the deposit.
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 aluminum window replacement
The difference between aluminum window replacement that lasts and aluminum window replacement 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.
