Is K Gill & Son Ltd 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 (WD24 5NJ) 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 Watford?
Use the "Get Free Quotes" form on this page. Your job details go to FENSA or Certass registered installers covering the WD postcode area, who contact you directly. Watford has 56 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.
Is new double glazing covered by a warranty?
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.
What is a FENSA or Certass certificate and why does it matter?
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.
