Durham Window Pros provides professional bay and bow windows in Durham, NC for residential and commercial properties across Durham County and the northern Triangle. A bay or a bow is the one product on this list we frequently talk people out of, and the reason is structural rather than a matter of taste. Before you fall for a photograph, we need to know what your wall is made of.
Start with what a bay actually is. It is not a window; it is a small room that projects out of the wall. It needs a floor, a seat board, a head, an insulated roof with its own flashing, and a way of transferring its own weight plus a snow and wind load back into the structure, usually through knee braces below or support cables anchored to the head framing.
In a wood-framed house that is routine work and we do it happily. There is a header to hang from, a rim joist to bear on, and a soffit to flash into. Given a sound wall, a well-built bay adds usable floor, daylight from three directions and genuine value to a room, and the 1990s and 2000s stock across south Durham takes them well.
In a brick bearing wall it is a different job entirely. There is nothing to hang a cantilever from. You are asking a masonry wall to accept a point load it was never designed for, which means a new structural opening, an engineered lintel and a review by somebody with a stamp. That work is load-bearing, so North Carolina's permit exemption for window replacement no longer applies at any price.
We have quoted that job and it is expensive, slow and occasionally refused by the building's exterior review because a projecting bay changes the elevation of a wall that was flat for a century. On a converted warehouse or a mill building our advice is usually to stop, and to buy the daylight a different way.
The alternative we recommend is a wide picture unit with operable flankers, or a box bay: a shallow projecting unit that hangs from the frame itself and needs no floor structure, no roof and no braces. On a garden window over a kitchen sink it gives you the shelf and the light without touching the wall's load path.
When we do build a bay, the details that decide whether it survives are all above and below. The roof gets a proper pitch, a metal cap flashing let into the wall above and an ice-and-water membrane, not a bead of sealant. The seat board cavity gets insulated to the same value as the wall, because an uninsulated bay floor is the coldest surface in the house.
Bows differ from bays only in geometry: four to six lites in a shallow arc instead of three at a fixed angle, and the arc means the projection is less and the load is smaller. If your heart is set on a curve and your wall is masonry, the bow is the version we can more often make work. Ask us before you order either.
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 bay and bow windows
The difference between bay and bow windows that lasts and bay and bow 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.
