What Happens During a Window Installation

Tuesday 18 August 2026·By Martins Windows

New windows can transform how a home looks and feels, but the actual installation process is often less familiar than the decision to get it done. Martins Windows, based in Heaton, walks customers through what to expect from measurement to finished fit.

The Process, Step by Step

  1. Initial survey and measurement. Exact dimensions are taken for each window, along with a discussion of style, glazing, and material options.
  2. Quotation. A detailed quote is provided covering materials, installation, and any additional work like brickwork adjustments.
  3. Manufacturing. Windows are made to the exact measurements taken, which typically takes some weeks depending on the order.
  4. Removing the old windows. Existing frames are carefully removed, with the opening prepared for the new installation.
  5. Fitting the new windows. New frames are fitted, sealed, and finished to ensure proper weatherproofing and insulation.
  6. Final checks. Windows are tested for smooth operation and a proper seal before the job is signed off.

How Long Does Installation Actually Take?

Fitting itself is often completed within a day for a standard house, though the wait for windows to be manufactured beforehand is usually the longer part of the overall timeline.

What to Check Before Booking

  • Is the quote clear about materials, glazing type, and what's included?
  • Does the installer offer a guarantee on both the windows and the fitting?
  • Will old windows and waste be removed as part of the service?
  • Are they experienced with your specific property type, especially for older homes?

Why Proper Installation Matters as Much as the Windows Themselves

Even high-quality windows can underperform if not fitted correctly — poor sealing or an imprecise fit undermines insulation and can lead to draughts or moisture problems over time.

Conclusion

Knowing what the process actually involves helps set realistic expectations before work begins. Martins Windows, rated 4.6 stars from 18 Google reviews, offers window installation services to homeowners across Heaton and Newcastle.
