Velux Windows in Sealant House

As certified Velux installers, we fit roof windows with absolute precision to ensure 100% weather tightness. Natural light transforms dark roof spaces into bright, breathable rooms.

When You Need Velux Windows

Your attic conversion or upstairs room feels dark and lacks natural daylight. Your existing roof windows are old, drafty, or letting water leak through the seals. You want to improve ventilation and reduce condensation in a top-floor room. You need an accredited specialist to ensure manufacturer warranties remain valid.

How We Do It

We help you select the correct window size, glazing specification, and opening style for your roof pitch. We cut precise openings through your roof tiles and underlying membranes without compromising roof strength. We install flashing kits correctly to ensure total watershed protection against heavy rainfall. We fit the internal lining, test the window mechanism, and clean up all debris before sign-off.

What to Expect

Most individual Velux window installations are completed within a single working day.
