What a window and door fitter does
Window and door fitters replace and repair uPVC, aluminium and timber windows, front and back doors, patio and bi-fold doors, and sort misted double glazing, broken hinges and locks. New windows in England and Wales must meet Building Regulations for energy and safety, and a fitter registered with FENSA or Certass can self certify, so in Harrow ask for the certificate before you pay the balance.

Frequently asked questions
My double glazing has misted up. Do I need new windows?
Usually not. A misted unit means the sealed glass unit has failed and can be replaced on its own, keeping the frame. If the frames are damaged or warped, or the hinges and locks are failing, a full replacement makes more sense.
What is FENSA and why does it matter?
FENSA and Certass are schemes that let registered installers self certify that replacement windows and doors comply with Building Regulations. Without a certificate you need building control sign off, and a buyer will ask for it when you sell.
Should I choose uPVC, aluminium or timber?
uPVC is the cheapest and lowest maintenance. Aluminium gives slim frames and large glass areas. Timber suits period homes and conservation areas and needs painting. Ask what the fitter mostly installs, because that is what they do best.
How do I get a quote from window and door fitters in Harrow?
Pick a listing on this page and send a quote request saying what needs doing and when suits you. The business comes back to you with a price and a time. It is free to ask, and no payment is taken online.
Are the window and door fitters on this page vetted?
Not yet. Listings marked Claimed have been claimed by the business and are kept up to date by them; the rest come from public records such as Companies House and Google and are marked as not yet claimed. Every listing shows its real Google rating and review count where one exists. We do not check registers or insurance yet, so ask for a Gas Safe or NICEIC/NAPIT number and check it yourself.
What should I check before I hire a window and door fitter?
Ask for a written quote and what it includes, who will do the work, whether they are insured, and any registration the trade needs, such as Gas Safe for gas work or a Part P scheme for electrics. Never pay the full amount up front.
Prices and availability are confirmed by each business. No payment is taken online, you pay the tradesperson directly.
