Why is my Velux window leaking when it rains?

Leaks are usually caused by a buildup of moss or debris in the external flashing, or by rubber gaskets that have perished over time. We can usually fix these issues without replacing the entire window.

Can you fix a leak without replacing the whole Velux window?

Yes. Most leaks can be solved by replacing the seals, clearing the flashing kits, or reglazing the glass. This is a faster and much more cost-effective solution than a full window replacement.

Is water dripping from my Velux handle a serious problem?

Yes, water dripping from the handle or ventilation flap indicates a failure in the window's waterproofing. It should be repaired quickly to prevent internal damp and plaster damage.

Is Your Velux Window Leaking?

A leaking roof window is more than just an inconvenience; if left untreated, it can lead to damp walls, ruined plasterwork, and even structural rot. At PMV Blinds & Maintenance, we specialise in identifying and fixing leaks in older Velux models that other companies might tell you need a full (and expensive) replacement.

Common Signs Your Velux Needs a Leak Repair:

Water Dripping from the frame: Often caused by perished seals and lack of servicing.
Damp Patches on Plaster: Brown staining around the window "reveal" usually indicates a failure in the external flashing or glazing seal.
Misting Between the Panes: This isn't just a cosmetic issue—it means your seal has "blown," and the window is no longer watertight or energy efficient.

Why is my Velux window leaking?

In our experience servicing Velux's across London, Hertfordshire, Bedfordshire, Essex, Oxfordshire and Cambridgeshire most leaks are caused by one of three things:

Blocked Flashing: Debris like moss and leaves builds up over years, forcing rainwater under your tiles instead of around the window.
Perished Gaskets: The UK weather causes rubber seals to crack over time. We can replace these with high-quality, long-lasting seals.
Aged Glazing Units: If the glass unit itself has failed, we offer a specialised Velux reglazing service to restore the window's integrity without removing the frame.

Is your Velux window experiencing leaks? We specialize in the repair of Velux windows and addressing leak issues.

Leaks in Velux windows can arise from various factors, with the most prevalent being the deterioration of seals over time.

Poor Velux installation

Improper installation of a Velux can lead to leaks, particularly when fitted at an angle below 15 degrees, as well as issues with flashings and felt We are available to assess and offer effective solutions to rectify these problems for you.

Velux condensation

Condensation is a common issue associated with Velux windows, which may be mistakenly perceived as a leak. In reality, this condensation results from internal dampness and becomes particularly noticeable during rainy weather. The vibrations caused by rainfall can cause condensation droplets to bead up and appear as if they are leaking.
