Ajs Construction (scotland) 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 (PA1 1JS) 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 PA postcode area, who contact you directly. Paisley has 59 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 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.

It's proof the window or door installation meets Building Regulations (thermal performance, safety glazing, ventilation) without a separate council building control sign-off. Without one, selling the property can mean paying for retrospective building control inspection or indemnity insurance, so keep the certificate with your house documents.

This directory holds 903 active window and glazing businesses across 48 towns in Glasgow, all from the Companies House register. Paisley accounts for 59, among the county's busiest. About 45% of Glasgow'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.
