Durham Window Pros provides professional casement and awning windows in Durham, NC for residential and commercial properties across Durham County and the northern Triangle. A casement is the tightest-sealing operable window made, and in Durham it is also the unit that rescues openings nothing else can serve. We specify more of them than the sales averages would suggest, and almost always for a structural reason rather than a stylistic one.
The sealing advantage is mechanical. A casement sash swings out and is pulled by its hardware against a continuous compression gasket on all four sides. A slider or a double-hung has to bypass itself, so it seals against brush pile and against nothing at all at the meeting rail. Air infiltration ratings for casements sit at the bottom of the scale for that reason.
That matters in a converted mill more than in a subdivision. The brick wall is thick, and the pressure difference across it on a windy day is genuinely felt at the opening. When people describe a loft as draughty, the draught is almost always a bypassing sash and a poorly finished perimeter, and moving to a compression-sealed unit fixes half of it in one step.
Then there is the egress problem, which is the real reason we keep casements in stock. An emergency escape opening needs 5.7 square feet of net clear opening, 24 inches minimum clear height and 20 inches minimum clear width, with the sill no more than 44 inches above the floor. A tall narrow mill opening cannot make that with a double-hung, because the sash only clears half the height.
A casement can. Swing the whole sash out of the way and the net clear opening is close to the full daylight dimension, less the frame. We have turned openings that no double-hung on the market could legalise into compliant bedrooms without cutting a single brick, which saves a structural review, a new lintel, a permit and several thousand dollars.
Awnings use the same hardware rotated ninety degrees: hinged along the head, swinging outward at the bottom. In this climate they earn their keep in summer: Durham gets afternoon thunderstorms that arrive fast, and an awning sheds rain away from the opening while still ventilating. We use them under fixed picture units in tall openings and in basements and stairwells.
Two honest cautions. A casement projects into the world, so it is a poor choice over a footpath, a deck walkway or anywhere a swinging sash meets a person. And the hardware does the work, so it matters: specify a multipoint lock that draws the sash at three points rather than a single throw, and a steel hinge arm rated for the sash weight you are actually hanging.
Hardware is also the repair we get called for most. Operators strip, hinge arms bind, and the sash starts to drop at the outer corner. Most of that is replaceable without touching the frame or the glass, and we carry the common operators. If your casements are sound and only cranky, that is a service call and not a replacement project.
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 casement and awning windows
The difference between casement and awning windows that lasts and casement and awning windows 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.
