About our installation partner, Help 2 Buy Windows
4.9/5 “Excellent” on Trustpilot — the UK’s No.1 double glazing installer. Read the reviews →
Two of our sealed units had misted up. They replaced the failed units quickly instead of pushing us into a whole new set of windows. Straightforward from quote to fit.Verified customer of Help 2 Buy Windows
The measuring visit was clear and unhurried — they talked me through the sizes and frame options before quoting. Fitters left everything spotless.Verified customer of Help 2 Buy Windows

Good to know
Replacement quote questions
Do I need a different quote for each window type?
Casement, sash and bay windows are measured and priced differently, so a quote built around your actual type is far more accurate than a one-size figure. Tell us what you’re replacing and we’ll match it.
Can you just replace the misted glass?
Often, yes. If the frames are sound and only the sealed unit has failed, replacing the glass alone can be enough. A surveyor will confirm what suits your windows at the assessment.
How are replacement windows measured?
A surveyor measures the opening rather than trusting the old frame, checking each side and the sill. Our measuring guide walks through it.
What does a quote cost?
The quote and home assessment are free and no-obligation. Funding and contribution options may be available subject to eligibility and a home survey, and any prices are confirmed after measuring.
Do you cover my area?
We match enquiries to installers covering postcodes across the UK. Add your postcode and we’ll route your request to installers working nearby.
Am I tied in by requesting a quote?
No. Requesting quotes puts you under no obligation to book. Compare what comes back and only go ahead if a quote is right for you.
