From Vermilion to Port Clinton.
We work in all of Erie, Huron, Sandusky and Ottawa counties.
Erie County
Sandusky, our home base
From the Victorian and Italianate houses near downtown and the Old House Guild district to the post-war ranches and capes off Perkins and Columbus Avenue, Sandusky has every kind of window opening. Older homes often have out-of-square openings and old weight-and-pulley sashes. Every window we build is measured and made for its own opening, so it fits without oversized trim covering the gaps.
More about SanduskyCommon questions.
How much do replacement windows cost?
Most standard vinyl replacement windows we install run about $450 to $900 each, installed. Bay, bow and garden windows cost more because they're larger assemblies. The quick quote on this site gives you a range for your project in about a minute, and the free in-home estimate gives you an exact price.
How long does installation take?
Most homes are done in a single day. Windows are custom-made to your measurements first, which usually takes a few weeks. We'll give you a date when you order.
Do you use subcontractors?
No. Our own installers do every job, and they cover your floors and furniture before they start.
Is there still a federal tax credit for windows?
No. The federal Energy Efficient Home Improvement Credit (25C) ended for windows and doors installed after December 31, 2025. If you installed in 2025, you can still claim it on your 2025 return. Ask us about current utility programs.
