Serving Genesee County &
the Surrounding Communities
For over 70 years, D&W Windows and Sunrooms has been designing, manufacturing, and installing windows, sunrooms, roofing, and siding for homeowners right here in Genesee County — all from our own 65,000-square-foot facility on Court Street in Davison, near Irish Road and I-69. That factory-direct approach means every window that goes into your home was built by us, not shipped in from somewhere else and marked up along the way.
From Flint and Grand Blanc to Fenton, Montrose, Otisville, and every township in between, D&W serves homeowners across cities, villages, and townships throughout the region.

From First Call to Finished Project
No matter which Genesee County community you’re in, every D&W project follows the same straightforward process.
Step 1:
Request Your Free Estimate
Call 1-800-833-9831 or fill out our online form. A local D&W consultant will schedule an in-home visit at a time that works for you — no obligation, no pressure.
Step 2:
In-Home Consultation & Measurement
We’ll walk your project with you, take precise measurements, and go over product options, energy performance, and financing. You’ll leave with a clear, itemized quote before you decide anything.
Step 3:
Custom Manufacturing
Once you approve your order, your windows or sunroom are built to spec at our Davison facility — not trucked in from an outside supplier. That’s what factory-direct actually means: your project is built for your home, by us.
Step 4:
Professional Installation
A trained D&W installation crew handles your project from start to finish, often completing standard window replacements in as little as a day. We clean up, walk you through your new products, and go over everything that’s covered under warranty before we leave.

Do all communities in D&W’s service area get the same products and pricing?
Yes. Every community on this list has access to our full product line, including The Michigan Window™, the Super Room® sunroom, custom bath systems, roofing, and siding — all manufactured at our Davison facility. Pricing and warranty terms are consistent regardless of which city, village, or township you’re in.
How do I know if D&W services my specific address?
If your city, village, or township appears on this page, we service your area. If you’re not sure which category your community falls under, or your address is just outside the list, call us directly and we’ll confirm.
Does D&W offer free estimates everywhere on this list?
Yes, every community we serve gets a free in-home estimate. A local consultant will visit, measure, and walk you through product and financing options at no cost.
Is D&W’s warranty the same in every location?
Yes. Because D&W manufactures its own products in-house, warranty terms are identical company-wide, whether you’re in Flint, Grand Blanc, or any of the townships we serve.
