Velux window replacement in Billingshurst for old roof windows that leak, mist up or stick. We swap the old window for a new one with fresh flashing, often in the same opening.
Condensation trapped between the panes, draughts around the frame, rot in a wooden frame, a window that won't open or close properly, and leaks in heavy rain all suggest the window is near the end of its life. Many roof windows fitted decades ago are now worn out.
Velux have kept many of their window sizes the same for years, so a new window often fits the existing opening without cutting the roof or the inside finish. That makes replacement a quicker, tidier job than most people expect, with very little mess inside.
A replacement is a good chance to upgrade. Newer glazing keeps heat in better, top-hung windows give a clearer view, and electric or solar windows open at the touch of a button. Built-in blinds or insect screens can be added at the same time.
We check the existing window, note the size code on its frame, and look at the flashing and the tiles around it. Your free quote covers the new window, a new flashing kit and any repairs needed to the opening.
On the day, we remove the old sash and frame from the outside, check the timbers around the opening, then fit the new frame and flashing kit and retile around it. Inside, the original lining usually stays in place, so there's very little making good.
Tell us what's happening with your roof. We aim to respond the same day, and there's no call-out charge.
We look at the roof, explain what we've found in plain terms and give you a free, no-obligation quote.
We carry out the work we quoted for, then talk you through what we've done before we leave.
The price depends on the size and type of window, the glazing and any extras such as blinds or an electric opener. Replacing in the same size opening keeps the cost down, as there's little work to the roof or the room. We give you a free quote first.
Usually, yes. A larger window means widening or lengthening the opening and trimming the rafters, so it's more work than a straight swap, and it may need building regulations approval. We'll check what your roof allows and explain the options before you decide.
On many models, yes. If the frame and flashing are sound and only the glazing has misted or cracked, a replacement sash or glazing unit can be fitted. If the frame is rotten or the window is very old, a full replacement is usually the better long-term choice.
A like-for-like replacement usually takes a few hours, and two or three windows can often be done in a day. Changing the size or type takes longer. We pick a dry day and keep the opening covered until the new window is fully sealed in.
