New windows are one of biggest investments you'll ever make on your home. Yet we frequently find windows that are not installed correctly and leak constantly.
We test all the windows and doors in your home to check if they're been installed correctly and that the factory fitted seals are working effectively.
Sometimes windows can be misaligned when they're installed, or lack the correct products to form a good seal with the rest of the building. Our pressurised smoke test can find every leak and help you diagnose any problems with your window installer.
Window reveals can also be a major source of leaks.
You will benefit from our construction design experience to pin-point the source of the problem to find the right solution
Saving energy!
The air leaks around windows and doors could account for 4% of the overall energy losses of the house.
Upgrading from old double glazed windows to new double glazed windows may only save 2 or 3% of your home, so airtight installation pays for itself
