Project Overview

A residential property in Watford required a new patio door to replace an old, draughty sliding door that had become difficult to operate and insecure. The homeowners wanted a stylish, secure, and energy-efficient solution that would provide easy garden access and enhance the property’s rear elevation. The goal was to install a white uPVC French patio door to create a classic, elegant look while improving thermal performance and security.

Our Solution

We supplied and installed a high-performance white uPVC French patio door tailored to the property’s style. The solution included:

  • White uPVC French door with two side-hung opening panels
  • A-rated double glazing with argon gas fill and low-E coating for superior thermal efficiency
  • Multi-point locking system on the active door leaf with anti-snap cylinders
  • Stainless steel friction hinges for smooth, controlled opening
  • Low-threshold cill for step-free garden access
  • Low-maintenance uPVC profiles that will not warp, yellow, or crack
  • Reinforced frames for added strength and security
  • Matching white handles and hardware for a cohesive finish
  • Concealed drop-down weather seals for superior draught protection

Installation Process

  • Conducted precise laser measurement of the existing door opening
  • Removed old sliding patio door carefully
  • Disposed of all waste materials responsibly
  • Inspected and prepared the structural opening, lintel, and sub-cill
  • Installed new uPVC French door frame using galvanised fixings and expanding foam
  • Hung both door panels on stainless steel friction hinges
  • Tested opening and closing operation and adjusted hinges as needed
  • Installed double-glazed sealed units into both door panels
  • Fitted multi-point locking mechanism and tested all locks
  • Applied internal and external silicone seals for full weatherproofing
  • Completed thorough clean of glass, frames, handles, and surrounding area
