What happens if it’s left?
Failed mastic isn’t a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that is needed. Problems with the glass or gaskets are for a window company, and we’ll say so. Around Compton, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
Why Compton clients choose us
- A sealant colour to suit the surroundings

About our window mastic in Compton
Frames and walls don’t move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. We are often asked to deal with damp patches on the reveal after heavy rain and gaps where the sill meets the wall, across window sills, timber windows & doors and aluminium frames.
Homes in small places like Compton often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
We stand behind the work with a 12-month guarantee, so you are covered after we have gone.

What happens on the day
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from an hour or two to a full day, depending on how many frames there are. In a small place like Compton, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Mention any parking rules near the property
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children

Water at the foot of a door frame isn’t always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We check before we reseal.

What window mastic looks like in Compton
With historic houses such as Loseley Park (about 1 mile east) nearby, there’s older building stock in the area around Compton as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Farncombe station, renewing tired window mastic between tenants heads off draught and damp complaints. Homes close to Church of St Nicholas include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

When to call us in Compton
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
Most people get in touch after spotting something like this:
- Cracked sealant at the sill ends
- Water coming in at the bottom corners of a door
- Cold air getting in at the frame edge
- Gaps left after new windows were fitted
Schools such as Loseley Fields Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

What sealant work cannot fix
In fairness, some problems need a different trade:
- A frame that has rotted at the joint
- Penetrating damp from a failed cavity tray or render
- Draughts through the window seals rather than the frame
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think.
