Our Window Installation Process

Design & Technical Consultation

Our process begins long before a tool touches your home. We meet with you to discuss your goals — lowering your MDU or Xcel energy bills, ending the cycle of painting old wood frames, or modernizing your home’s look — and help you choose double-hung, casement, and other styles that fit your architecture. Then our technicians take a true-fit precision measurement of every opening — width, height, and depth at multiple points — so your custom-built windows arrive with a tolerance under 1/8th of an inch.

Custom Engineering & Manufacturing

Off-the-shelf windows from big-box stores are built for a national-average climate. Yours are custom-built with glass packages selected for Northern Climate Zone 5 — specialized Low-E coatings and gas fills that retain heat through a North Dakota winter and reflect the intense prairie sun in summer.

Preparation & Site Protection

On installation day, our factory-trained crew arrives in a fully equipped mobile workshop — and our first priority is your home, not your windows. We lay protective drop cloths and floor runners, set up a designated cut station and staging area outside, and keep heavy equipment and debris out of your living space. We’ll ask you to move furniture back from the windows, and we’re always happy to help with the heavy lifting.

Careful Removal & Structural Audit

Removing an old window takes finesse — rip it out and you risk the vapor barrier, exterior, and interior drywall. As we remove the old sashes and frames, we perform a structural audit looking for:

• Hidden wood rot from failed seals in the old windows
• Insect damage that may have compromised the rough opening
• Insulation gaps — empty pockets where the original builder skipped insulation

If we find these issues, we address them properly — so your new windows sit on a solid, healthy foundation.

Weather-Tight Installation

We use a full-frame or insert method depending on your home’s needs, with the same core sealing technology either way:

• Level, plumb & square: high-precision leveling so the frame is perfectly square — critical for long-term operation and seal life.
• Closed-cell thermal foam: instead of fiberglass batting (which can trap moisture and grow mold), we use low-expansion, closed-cell polyurethane foam that seals every gap, won’t bow the frame, and acts as a secondary vapor barrier.
• Integrated flashing & capping: custom-bent aluminum capping directs rain and melting snow away from your walls — a maintenance-free finish matched to your window color.

Professional Finishing & Cleanup

We’re not done until your home looks better than when we arrived. We apply color-matched, furniture-grade interior caulking for the final air seal, then perform a white-glove cleanup: vacuuming interior floors near the work zones, magnet-sweeping the lawn for stray screws, and cleaning your new glass so you can enjoy the view right away.

Final Walkthrough & Education

The lead installer walks you through every window — how the locks work, the tilt-in cleaning feature on double-hung models, how to remove the screens — so you’re fully confident using your new windows. We finish with a quality-audit sign-off against our “Window & Door Store Standard,” and only consider the project complete when you’re completely satisfied.
