This directory does not confirm registration. Window and door installers self-certify their work against Building Regulations through a Competent Person Scheme — mainly FENSA or Certass — so check the company name or postcode (SL1 4XE) directly on the FENSA or Certass website before booking, and ask to see the certificate number.

Use the "Get Free Quotes" form on this page. Your job details go to FENSA or Certass registered installers covering the SL postcode area, who contact you directly. Slough has 45 registered window and glazing businesses in this directory, though the installers who quote are not necessarily among them. It is free and there is no obligation.

Not much, but not none. Wipe the frames a few times a year, lubricate hinges and locks annually, and keep the drainage channels along the bottom of the frame clear so water can't pool and find its way inside. There is no statutory annual service like a boiler needs.

uPVC frames typically carry a 10 year manufacturer or insurance-backed guarantee, and sealed glazed units are usually guaranteed separately for 5 to 10 years against misting. Register the guarantee after installation and keep the FENSA or Certass certificate — a buyer's solicitor will ask for it if you sell the property.

This directory holds 265 active window and glazing businesses across 35 towns in Berkshire, all from the Companies House register. Slough accounts for 45, among the county's busiest. About 31% of Berkshire's registered window and glazing firms were incorporated in the last three years, so weigh incorporation date and FENSA/Certass registration, not just company age.
