We had George and Josh come and fit our door and they were excellent at the job. Made us aware of what they were doing and when they came across and issue asked us how we wanted them to proceed. They told us the pros and cons of each which gave us the knowledge of what option to pick. Highly recommend this company

Ideal Glass installed a pair of French doors for us in a garden room in December 25. Over the last 10 months the doors have naturally dropped and the hot weather may have shrunk the structure. Ideal Glass sent their Installer George to carry out a service visit. He realigned the doors successfully and serviced the key components in about 20-30 minutes. As it was within a year of installation they did this free of charge. Excellent quick and courteous service. James

Ideal Glass is FENSA registered

A FENSA certificate is not merely a luxury; it's a necessity, especially for those seeking Windows & Door Installation services in Watford. This certification ensures that you are collaborating with a reputable company that adheres to essential legal standards and offers vital protection for your home. Many people lack the time, expertise, or desire to verify these crucial aspects on their own. So, what should you know?

A FENSA certificate guarantees that the installer responsible for your windows or doors has adhered to Building Regulations. Furthermore, it signifies that your installation has been recorded with the Local Council, which is a legal obligation. Proof of compliance is particularly important when selling your property in Watford.

Moreover, any FENSA certificates issued after June 6, 2014, confirm that the installer’s warranty is backed by insurance. This is an important safety net should unexpected issues arise or if the company encounters financial difficulties.

In summary, you’re not just requesting a FENSA certificate; you’re verifying that your chosen window or door installer in Watford is professional, in compliance with Building Regulations, capable of registering your installation, and providing an insured warranty.

That’s why we emphasize that the FENSA certificate is the ultimate proof of a job well done.
