Franklin Window Replacement provides professional bay and bow windows in Franklin, TN for residential and commercial properties across Williamson County. A bay or a bow is less a window than a small piece of building pushed out past the wall plane. Nearly everything that goes wrong with one goes wrong because somebody treated it as a window purchase rather than a construction detail.
The distinction between the two is geometry. A bay is three units set at angles, usually thirty or forty-five degrees, with a wider fixed center and two operating flankers. A bow is four or more equal units stepped around a shallow curve, which reads softer from the street and takes a wider opening to look right.
Both need to carry their own weight and yours. The seat board, the head board and the framing behind them are structure, and the assembly is typically supported either by knee braces below or by cables from the header above. On a second-story projection or a deep unit with a stone seat, the support has to be engineered rather than assumed, and we will say so before quoting.
The roof over the projection is where mixed-humid weather does its work. A bay roof is a small, low-slope surface with three or four transitions and a headwall against the house, and it sits under whatever the main roof sheds onto it. It wants a proper membrane under the finish, step flashing up the sidewalls, and a counterflashed or well-lapped headwall junction. Almost every rotten bay we open failed there first.
The cavity under the seat board is the second failure point and an easy one to fix at the right moment. It is a projecting floor exposed to outside air on three sides plus underneath, and builders routinely put two inches of batt in it and call it done. During installation it should be air-sealed and packed properly, because it is the coldest surface in the room in January and the first place condensation shows.
Glass choice deserves the orientation argument. A bay usually goes on the front or the back of the house, and if that face is west, you have just added a substantial area of afternoon glass to the room. Since the residential energy table here sets no solar heat gain ceiling, nobody will stop you, which is exactly why the decision has to be made on purpose rather than by default.
There is a version of this project we recommend against. Replacing an existing bay in kind, on a wall where the projection is failing because it never had adequate flashing or support, costs a great deal and reproduces the original problem. Sometimes the right answer is a large fixed unit with flanking casements in the flat wall, and the room ends up brighter and drier for less money.
When the detail is right these are the best rooms in the house. Deep sill, real daylight from three directions, and a seat that ends up holding books, plants and at least one cat. We build the framing, flash the roof, insulate the cavity and set the glass as one job, because splitting those across trades is how bays fail.
Our insured team brings the right materials and equipment to every job — soft-coat low-E coating on surface two, stainless steel warm-edge spacer, argon-filled dual-lite sealed unit, pultruded fiberglass sash profile, fusion-welded sash corner joinery, polyamide thermal break strut — and backs the work with a written workmanship warranty. We serve Franklin and nearby communities including Brentwood, Spring Hill, Nolensville, Thompson's Station.

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 soft-coat low-E coating on surface two, stainless steel warm-edge spacer, argon-filled dual-lite sealed unit, pultruded fiberglass sash profile, 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 Franklin 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 Williamson County means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Franklin Chooses Franklin Window Replacement
- ✓We write the solar heat gain coefficient wall by wall instead of house-wide, because the county code sets no ceiling on it and a west elevation and a shaded south elevation want opposite answers.
- ✓Insert and full-frame approaches are priced side by side on the same estimate, so you can see what keeping your existing frame saves and what it costs you in daylight opening.
- ✓Every sill gets probed with an awl before we recommend an insert, because burying a new unit inside a soft frame hides the problem for about five years and then costs twice.
- ✓Pans go under every opening the framing allows, sloped outward with dammed ends and a raised back edge, because flashing decides whether a mixed-humid wall stays dry long after label numbers stop mattering.
