Tonec Installations Limited

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 (L6 5DR) 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 L postcode area, who contact you directly. Liverpool has 280 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.

Not here. This is a register-based directory, not a review site. Look at independent review platforms, ask the installer for recent local references, and confirm FENSA or Certass registration before any work starts.

This directory holds 729 active window and glazing businesses across 43 towns in Merseyside, all from the Companies House register. Liverpool accounts for 280, among the county's busiest. About 41% of Merseyside'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.
