A Holmen window project we are proud of
In summer 2026 we replaced the windows and patio door on a Holmen home as part of a full exterior refresh that also included siding, fascia and gutters. Replacing everything together meant matching finishes, one coordinated schedule and a home that looks and performs better from every angle. See the before and after photos.

What to check before you call
Walk around the house on a cold day and look at each window. Does the frame feel cold to the touch? Can you feel air moving near the edges? Does the window open and lock smoothly? Look for water stains on the sill, soft or peeling wood and any cloudiness between panes. If you spot two or more of these, a replacement conversation is worth having.
Window styles to consider for your home
- Double-hung: classic look and easy operation.
- Casement: hinged for strong ventilation and a snug closed seal.
- Slider: good for wide, short openings.
- Picture and bay: more light and a bigger view where you want it.
Questions worth asking any window company
- Is the company licensed and insured?
- Which brands do you install, and what warranty do they carry?
- What is included in the estimate?
- How is the crew supervised, and how will the job site be protected?
Bring these to your consultation. We will answer each one plainly.
Comfort through every season
Windows affect more than winter heating. In summer, sun through older glass can heat up rooms, and in any season, poor seals let in noise, dust and moisture. New windows that fit well and seal tightly make rooms feel steadier, quieter and easier to heat and cool. We will talk through which rooms get the most sun and which ones feel coldest so your windows solve the problems you actually notice.
Getting ready for installation day
Clear the space around each window, take down blinds and curtains, and move small furniture away from the walls. Let us know about pets or anyone working from home so the crew can plan around you. The team will protect your floors and clean up as the work moves along.
