Replacement Windows, Done by One Local Company Start to Finish
Wood Windows Inc has replaced windows in Boise homes since 1980. The person who measures your house, the carpenters who install your windows, and the office that handles your warranty all work for the same Garden City company. Nothing gets handed off to a subcontractor you've never met.
Because we're an authorized dealer for several manufacturers, we can recommend the window that fits your house and budget instead of the one brand we happen to sell. That might be quality vinyl for a 1990s Meridian subdivision home, fiberglass for a west-facing wall that bakes every afternoon, or clad-wood to keep the character of a North End bungalow.

Signs It's Time to Replace Your Windows
- •Fogged or hazy glass between the panes — the seal has failed and the insulating gas is gone.
- •Drafts and frost on the inside of the glass during January inversions.
- •Single-pane glass or 1970s–80s aluminum frames that sweat and conduct cold.
- •West-facing rooms that overheat and fade floors and furniture every summer afternoon.
- •Sashes that stick, won't stay open, or won't lock.
- •Soft or rotted wood at the sill — water is getting into the wall.

Insert vs. Full-Frame Replacement
Insert (pocket) replacement sets a new window inside your existing frame. It costs 15–30% less and leaves interior trim and siding alone. It works well when the old frames are square, dry, and solid.
Full-frame replacement removes everything down to the rough opening, so we can inspect the framing, re-flash, and insulate the gaps properly. It's our usual recommendation for Boise homes older than about 25 years, where hidden rot and failed flashing are common.
We'll show you which your house needs during the measure. You won't get a one-size-fits-all pitch.

Window Replacement Questions, Straight Answers
How much does window replacement cost in Boise?
Most Treasure Valley homes run $650–$1,800 per window installed depending on material — quality vinyl at the lower end, clad-wood at the upper end. A typical 10-window home lands between $8,000 and $16,000. Your quote is a firm written number after a free in-home measure.
Who actually installs my windows?
Wood Windows Inc employees — licensed, experienced carpenters on our payroll. We have never used subcontractors in 46 years of business. The crew that installs your windows answers to us, and so does your warranty.
Which window brands can I choose from?
We're an authorized dealer for Andersen, Marvin, Milgard, Kolbe, All Weather Windows, and Velux. Because we carry multiple brands, our recommendation fits your house and budget — we're not locked into pitching one manufacturer.
How long does window replacement take?
Measure appointment this week, manufacturing typically 3–8 weeks depending on brand, then most full-house installs finish in one to three days. We schedule installation as soon as your windows arrive.
Should I get insert or full-frame replacement windows?
Insert (pocket) windows reuse your existing frame and cost 15–30% less, but they hide any rot and shrink the glass. Full-frame replacement strips to the rough opening so flashing and insulation are redone properly. For most Boise homes older than about 25 years we recommend full-frame; newer homes with sound frames are often good insert candidates. We'll tell you which after looking at your actual frames.
Can you replace windows in winter?
Yes. We replace one opening at a time, so your home is only open for minutes per window, and cold-weather installs are routine for Idaho crews. Winter is also when install calendars are most open.
Do you replace windows in historic North End and East End homes?
Yes — older Boise homes are some of our favorite work. We can match original sightlines with wood or clad-wood windows from Andersen, Marvin, or Kolbe, and we're familiar with the City of Boise's historic-district review process.
Do you offer financing?
Yes. Financing can spread a whole-house project into a monthly payment — ask your project consultant for current options, or see our financing page.
