How much does window replacement in St. Paul cost in 2026?
Modern Exterior Systems (Modex) installs ProVia, Kolbe, and Pella windows across St. Paul. A lot of this city was built before 1940 — the wood double-hungs in Summit Hill, Crocus Hill, Mac-Groveland, and Highland Park are beautiful and almost always single-pane, drafty, and a few coats of paint away from sealed shut. Most full-house St. Paul window replacements run $25,000 to $180,000+ on an average 18-window home in 2026, depending on line and glass package. ProVia Endure at the value tier ($1,400–$2,500/window). Kolbe Heritage for true historic restoration, when the sightlines have to match the original ($2,500–$6,000/window installed). Pella spans every tier from 250 Series through Reserve.

Approach
Three premium window brands, deliberately chosen
Modex installs ProVia, Kolbe, and Pella windows because they deliver triple-pane Low-E performance, frame durability through Minnesota winters, and warranty depth that protects your investment for decades. We do not install commodity brands or offer bait-and-switch pricing—every window we quote meets the same performance standard.
Performance
Triple-pane Low-E glass handles Minnesota winters
At -20°F, double-pane windows lose significant heat. Triple-pane Low-E with argon or krypton fill is the baseline on every Modex full-house quote. This glass standard applies across ProVia, Kolbe, and Pella—no exceptions for budget projects.

Brands
ProVia, Kolbe, and Pella at a glance
Three brands, three buyers. What each one is best at and where it lands on price.
Is there a federal tax credit for windows in 2026?
No. The federal 25C tax credit — 30% (up to $600 per year) on ENERGY STAR windows — expired December 31, 2025, and there's no federal replacement for 2026. Minnesota has no separate state window credit either. Projects placed in service on or before December 31, 2025 may still qualify on your 2025 return — check with your tax preparer. For 2026 installs, the savings come from the windows: triple-pane Low-E from ProVia, Kolbe, and Pella cuts Twin Cities heating bills 10–15%.

Why choose
Three reasons Modex stands apart
Premium brands. Replacements that look like they belong. Warranties that outlast the trim.
Reason
Three premium brands, no commodity swap
Modex installs ProVia, Kolbe, and Pella because they deliver triple-pane Low-E performance and frame durability through Minnesota winters. We do not stock or quote commodity-tier vinyl. Every quote — Aspect to Heritage to Reserve — meets the same install and warranty standard.
Replacements that look like they belong
On older homes — 1920s craftsman bungalows in Linden Hills, Tudor restorations in Edina Country Club, lake-corridor customs in Wayzata — plain replacement windows make a house look wrong. We measure the original divided-light pattern and order new windows that match it, so the replacements read as original architecture, not as a budget swap.
Lifetime workmanship on a 5–10 year industry standard
Most window installers warranty workmanship for 5 to 10 years. Modex backs every residential window install for as long as you own the home. Material warranties from ProVia, Kolbe, and Pella are registered in your name and transferable per the manufacturer's terms if you sell.
Free estimate
Modex walks through your home, measures every opening, and discusses brand fit. No pressure, no sales pitch. See /our-process for the full timeline.
Custom quote
We build a detailed quote with brand, product line, glass options, and honest line-by-line pricing. No hidden fees.
Professional install
Modex crews handle removal, frame prep, installation, and cleanup. Most full-house jobs complete in 5–7 business days.
Recent installs
Kolbe Heritage on a Country Club Tudor restoration, ProVia Endure on a Bearpath walkout, Pella Reserve on a Wayzata lake home—each selected for neighborhood character and performance demands.
