Dayton
Specialty & Shaped Windows for Dayton homes
Dayton, Kentucky, sits right on the Ohio River in 41074, and its historic streets hold some of the region's best Victorian, Italianate, and shotgun homes, many with tall round-top windows, arched transoms, and the occasional oval. Those shapes are a huge part of the character, and they are also the hardest to replace because every curve is specific to the opening. Old single-pane glass in a rotting frame is common up and down these blocks.
We template each shape on site so the replacement stays true to the house. Bulldog builds arch, round-top, oval, and half-round units in triple-pane Low-E glass with argon fill inside a fusion-welded vinyl frame, and we match the color and grid to keep the period profile. These are built fixed for the tightest seal, and because each is custom-templated it costs more than a stock rectangle. Our lifetime product and labor warranty covers the whole install.
Specialty Windows
Custom Shapes, Templated to Fit
Some openings aren’t rectangles. Specialty and shaped windows are custom-built to match — an arch over the front door, a half-round in the gable, a trapezoid following the roofline. They’re usually fixed for a clean look and full efficiency, and we template each one to your exact opening.
Want the bigger picture? Pair it with replacement windows or a new entry door, and ask about rolling it into one 0%-for-24-months project. For efficiency ratings, the Energy Star program is a good reference.

Common questions
Specialty & Shaped Windows FAQs
I own a Victorian in Dayton and want to keep the round-top windows original but stop the drafts. Can you do that?
Yes. We template the round-top exactly so the shape and proportions stay period-correct, then build it in triple-pane Low-E glass with a fusion-welded vinyl frame. You keep the Victorian character and get modern efficiency, which matters on the river where wind off the water drives the drafts.
Can you match my existing arched windows?
In most cases, yes. We template the opening and build a shaped unit to match the radius and proportions of what’s there.
Do shaped windows open?
Most are fixed, which keeps the look clean and the seal tight. Certain shapes can be built to operate — we’ll tell you what’s possible for your opening.
Are specialty windows more expensive?
Custom shapes cost more than a standard rectangle because each is templated and built to order. We give you an exact number at the free consultation.
