Is The Ass Group Limited FENSA or Certass registered?
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 (DA14 4DT) directly on the FENSA or Certass website before booking, and ask to see the certificate number.
How do I get a quote from a window installer in Sidcup?
Use the "Get Free Quotes" form on this page. Your job details go to FENSA or Certass registered installers covering the DA postcode area, who contact you directly. Sidcup has 38 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.
Should I repair or replace my windows?
Repair makes sense for a failed seal (misted double glazing), a worn handle or hinge, or a damaged lock on an otherwise sound frame — usually a straightforward swap. Replacement is the better value once frames are warped, draughty, rotten (on timber) or past roughly 20 to 25 years old, or when several units across the house have failed. Ask the installer to price both where it's borderline.
How many window and glazing companies are there in Kent?
This directory holds 478 active window and glazing businesses across 41 towns in Kent, all from the Companies House register. Sidcup accounts for 38, among the county's busiest. About 26% of Kent'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.
