Replacement windows

The right window for every room.

We carry double-hung, casement, slider, awning, bay, and bow windows. Every project starts with a free in-home measurement — because no two openings are exactly the same.

Bay window with strong curb appeal

Bay & bow windows

Energy efficiency

Double- and triple-pane glass with low-E coatings and argon fill reduce heat transfer — important in Iowa's hot summers and cold winters.

Noise reduction

Laminated glass options reduce outdoor noise, which matters near busy roads, train corridors, or neighborhoods in Davenport and Burlington.

Proper measurement first

Older Iowa homes often have non-standard opening sizes. We measure before we order — every time — so windows fit right the first time.

Exterior siding

Protect the outside. Upgrade the look.

Aging wood or aluminum siding lets in moisture, drives up energy bills, and drags down curb appeal. We install vinyl and James Hardie fiber cement siding that holds up to Iowa weather for decades.

We measure before we order

Iowa homes — especially older ones in Burlington, Keokuk, and Iowa City — often have non-standard opening sizes. Measuring first prevents costly remakes and delays.

Replacing all your windows or re-siding your home is a significant project. We offer financing options so you can move forward without waiting to save the full amount.

"They measured everything before ordering and the windows fit perfectly. The crew was clean and finished on time. Worth every penny."

— Burlington homeowner, 14 windows replaced

"We went with James Hardie on the front of the house and vinyl on the sides. They explained the tradeoffs clearly and the finished project looks great."

— Iowa City homeowner, full re-side

"I called three companies. These guys gave me a written quote the same week and never called me five times afterward pushing me to sign. Easy choice."

Common questions

What homeowners ask before they call.

How much do replacement windows cost in Iowa?

Window replacement costs vary based on style, size, glass package, and installation conditions. Installed prices commonly range from $400 to $1,200 per window. A whole-home project of 8–12 windows typically runs $5,000–$12,000. Use our estimator tool on the windows page for a planning range, then request an in-home measurement for a real quote.

What is the difference between vinyl siding and James Hardie siding?

Vinyl siding is lower cost, never needs painting, and is lightweight to install. James Hardie fiber cement is heavier, more impact-resistant, holds paint longer, and is non-combustible (Class A fire rating). Hardie looks more like wood and is a strong choice for homes exposed to hail or where fire resistance matters. Both are major upgrades over aging wood or aluminum siding.

Do you serve the Quad Cities area?

Yes. We serve Davenport, Bettendorf, Rock Island, Moline, Le Claire, and surrounding Quad Cities communities. We also cover Burlington, Iowa City, Fort Madison, Keokuk, Muscatine, Mount Pleasant, Fairfield, and most of Southeast Iowa. Call us at (319) 318-0670 if you want to confirm your specific location.

How long does a replacement window project take?

Most single-day crews can install 6–10 windows. Larger whole-home projects may take two days. Lead time from signed agreement to install is typically 4–8 weeks depending on the window style and current production schedules. We give you a realistic timeline before you commit.

Do replacement windows actually lower energy bills?

Modern double- or triple-pane windows with low-E coatings and argon gas fill meaningfully reduce heat transfer — important in Iowa where summers are hot and humid and winters are harsh. The actual savings depend on your current windows, home size, and heating/cooling system, but most homeowners replacing single-pane or older double-pane windows notice a comfort difference immediately.

Can I replace just a few windows instead of the whole house?

Absolutely. Many homeowners start with the draftiest rooms, damaged windows, windows that are hard to open, or high-visibility front-facing windows. There is no requirement to replace everything at once. We'll give you a quote for any scope — one window or all of them.

What if my window openings are an unusual size?

We handle this regularly. Older homes in Burlington, Keokuk, and the Quad Cities area often have non-standard opening sizes from original construction or previous remodels. We measure every opening before ordering and can source custom-sized windows for openings that don't match standard dimensions.

Do you offer financing for windows or siding?

Yes. Replacing all your windows or re-siding a home is a significant project. We offer financing options that allow you to move forward without waiting to save the entire amount. Ask about available plans when you request your quote.
