Columbia TN Window Pros provides professional bay & bow windows in Columbia, TN for residential and commercial properties across Maury County and the Duck River valley. A bay or a bow is not really a window. It is a small piece of structure that projects out of your wall, carries its own load, has its own roof, and therefore has its own ways of leaking. Price it and inspect it as construction.
The projection has to be supported. Most bays are carried on a combination of knee braces below and cable supports from the head into the framing above, and the cables need tensioning at installation and occasionally after. A bay that has dropped at the outer corner and now binds its sash almost always has a support problem rather than a window problem.
The roof over it is where Maury County's severe weathering rating shows up first. That little roof is small, it is often low pitch, it collects debris from whatever is planted near the house, and it flashes into a wall at a head height nobody looks at. We build it with a proper cricket where the pitch demands it and step flashing into the wall, not a bead of sealant.
The seat and the head cavity have to be insulated and air sealed like exterior assemblies, because that is exactly what they are. An uninsulated bay seat is a cold plate under a window, and in a humid Middle Tennessee winter it is the surface in the room most likely to condense. Rigid foam under the seat board and a sealed perimeter fixes it permanently.
Bows differ from bays in geometry rather than concept. A bow uses four to six equal units at shallow angles to make a curve; a bay uses a wide center with two flanking units at thirty or forty-five degrees. The bow reads softer and costs more per unit of opening. Neither is technically superior and both are structure before they are windows.
Configuration is where we push people. A bay with a fixed center and two operable casements or double-hungs at the flanks ventilates properly and keeps the big glass in the cheapest, best-sealing unit there is, which is a fixed lite. An all-fixed bay looks the same on day one and is a mistake by August.
Egress deserves a check on any bay in a bedroom. The flanking units are narrower than they look and the clear opening on an angled flank can fall short of what an escape opening needs. We run those numbers at measure, in writing, before the order goes in. Finding out after delivery that a flank is an inch short is an expensive way to learn arithmetic.
Replacing an existing bay in kind is usually straightforward. Adding one where there was a flat wall is a structural alteration that touches the header, the roof and the exterior finish, and it needs a permit and a plan. We are happy to do it and we will not pretend it is a one-day window swap.
Our licensed and insured team brings the right materials and equipment to every job — co-extruded rigid PVC frame, AAMA 2605 fluoropolymer finish, NAFS design pressure rating, self-adhered flashing at the sill corners, desiccant-filled spacer channel, silicone-foam glazing tape — and backs the work with a written workmanship warranty. We serve Columbia and nearby communities including Spring Hill, Mount Pleasant, Lewisburg, Chapel Hill.

Materials, equipment and how we do bay & bow windows
The difference between bay & bow windows that lasts and bay & 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 co-extruded rigid PVC frame, AAMA 2605 fluoropolymer finish, NAFS design pressure rating, self-adhered flashing at the sill corners, 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 Columbia 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 Maury County and the Duck River valley means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Columbia Chooses Columbia TN Window Pros
- ✓Maury County publishes its own design criteria sheet, and it grades this ground severe for weathering, moderate to severe for decay and moderate to heavy for termites. We treat those three lines as the specification, not as trivia, and every material recommendation on this site starts from them.
- ✓We flash the sill on every opening, including the ones nobody will ever inspect. A sloped pan with a back dam and turned-up ends costs us an hour and it is the single detail that decides whether the framing under your new window is sound in fifteen years.
- ✓We give you the certification number for the glass package before you sign, not after. If a competing quote will not produce one, you are being asked to buy a number that nobody has verified.
- ✓Tennessee does not require a state license below $25,000 and Maury County did not adopt the Home Improvement license, which means the legal floor for residential window work here is very low. We say so out loud rather than hiding behind a badge.
