Fensa-Registered
Our reliable and certified team is FENSA-registered. For those who don't know, FENSA stands for Fenestration Self-Assessment and is a government-authorised scheme that monitors building regulation compliance for replacement windows and doors. In friendly terms, a FENSA certificate assures you that the window/door installer who fitted your windows/doors has complied with Building Regulations and registered the installation(s) with the Local Council; both are legal requirements! If you ever decide to sell your home or business premises, proof of them is essential.
High-Security
Windows and doors provide the ultimate gateway for opportunist thieves to enter a property; don't make yourself a target with rickety frames and weak security locks. Upgrade your windows and doors or request repairs to ensure they are functioning at their best. Our double-glazed windows and robust doors add an extra layer of security to your home or workplace with top-notch British-standard locking systems that effectively deter opportunists from breaking in. We deliver peace of mind to home and business owners across Southeast England. Sleep at night knowing your loved ones and assets are safe!
Insurance-Backed Guarantee
At Instant Windows & Doors, we use the best energy-rated systems available on the market and include a 10- year insurance-backed guarantee with every window and door installation. It is also worth mentioning that our windows and doors are backed by the Home Improvement Protection Scheme for your safety and investment security.
