Fixed a sagging heavy aluminium/glass door that no one else could solve for over a decade!
I suffered more than a decade with a problem with my wide heavy aluminium/glass balcony door in my flat that was sagging and scraping on the sill, and numerous tradesmen coming to assess it, none of whom were able to solve it. One even referred me to a company to replace the entire frame system for the door and surrounding windows for over £4k! Thermalseal were able to visit and identify the problem immediately. They faced several surprises that required much additional time, and they stuck at it relentlessly in the tiring heat, no extra charge. The problem is now fixed and fixed well!Job location: E15RJason P8.67 UPVC Windows Repair
