Your Guide for How to Fix a Leaking Window Sill

how to fix a leaking window sill

It seems almost ludicrous that the very things we install to stop water entering our homes can be the reason why water is getting in. The sad reality is, a lot of window sills leak, and without a bit of TLC, they could cause some major problems.

Windows sills may be one of the smallest spaces in our homes, but there are some wonderful ways to get creative with them. Seeing water leaking in and pooling around the window sill can be incredibly troubling, and for good reason – that water is not supposed to be there.

When a window system fails, leaks and draughts are very often the result. This is normally due to a break in the seal around the window.

A little break can cause a world of problems, exposing your home to water damage, sending your energy-efficiency plummeting, and potentially causing some big structural damage or aesthetic problems.

Thankfully, how to fix a leaking window sill is not as difficult as it might seem and shouldn’t take you too long. To bring your window sills back up to scratch, check out our 4-step guide!

Your 4-Step Guide to Window Sill Repair

Fixing a leaking window sill is quite straightforward, and generally involves re-caulking. Caulk is what is used to form a seal around the window in the first instance, but can thankfully be re-applied.

Step One:

The first stage of the process is to assess the damage and check on the existing caulking around your windows. While faulty caulk is commonly the cause of leaking windows, allowing condensation to easily form and moisture enter your property, it is not the only cause.

More serious problems could require enlisting a professional to help you decipher the problem by examining your windows.

The final stage of preparation is to fully dry the area. This includes the area that you have cleaned, but also any cracks or crevices where additional moisture is hiding

Step Two:

If you have noticed broken or missing caulking around the problem area, then you need to remove it before proceeding.

All the caulk should be removed from the windows and then you need to make sure the area is clean.

Step Three:

The final stage of preparation is to fully dry the area. This includes the area that you have cleaned, but also any cracks or crevices where additional moisture is hiding.

Leaving any moisture on the windows could render the finish inefficient.

Step Four:

Once the area is prepared, you can apply the caulk to the window frames. The caulk should be quite easy to use, and the process of applying it very simple.

You should make sure that the entire exterior seal of the frame is covered, and any excess caulk wiped away.

How Can I Stop the Problem of a Leaky Window Sill Permanently?

Re-caulking your windows is a great measure to take to fix a leaking window sill, but if you want a more permanent solution, then you may want to consider upgrading your windows.

Modern window units that have been properly installed, shouldn’t cause any problems with broken seals, and if you get the right system, you also shouldn’t encounter condensation problems.

Triple-glazing is becoming more and more popular in the UK for its enhanced ability to stop problems like condensation. This protection is built into the design of triple-glazing, and primarily revolves around the central pane.

The pane is designed to force warmth back into a property and stays at a relatively high temperature – one of the best ways to help homes stay warmer.

As condensation relies on warm air hitting cold surfaces, it is much less likely to form on the warmer triple-glazing unit. This makes the whole system better at conserving energy, but also increases the protection of your home.

The added strength of triple-glazing is a great burglar deterrent, provides fantastic sound insulation, and is simple to maintain.

When modern triple-glazing is combined with the strength of vinyl window frames, you can rest easy knowing that your home is better prepared to deal with the elements and keep that moisture outside where it’s supposed to be.
