Window mastic in West Wycombe, done properly
The new joint does not have to be white. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. We work on patio & French doors, composite doors and uPVC windows, and people most often call us about leaking joints at the ends of sills and cracked or shrunken mastic around the frame.
Around West Wycombe, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
You’re covered for a year from the day we finish. If anything is not right with it, ring 0345 464 0079 or email us.

When to call us in West Wycombe
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.
It’s worth asking for a quote if you see:
- Cracked sealant at the sill ends
- Damp patches on the reveal after heavy rain
- Black, perished sealant on frames
- Cold air getting in at the frame edge
For landlords with property near Saunderton station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Draughts through the window seals rather than the frame
- A sash or casement that will not close properly
- A failed sealed unit that has misted up

Frames and glazing around West Wycombe
With historic houses such as West Wycombe Park House (about 0.3 miles south) nearby, there’s older building stock in the area around West Wycombe 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. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near Congregational Church, the joint between an old wall and a newer frame is usually the first place rain gets in. Schools such as West Wycombe Combined School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Walk round the house once a year and look at the joints
- Do not aim a pressure washer at the joints
- Don’t use solvent cleaners on the joint
- Keep paint off silicone joints
Keep the new mastic undisturbed while it cures, for as long as we advise. Don’t point a pressure washer at the joints.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
What happens on the day
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a handful of frames, longer for a whole house. Somewhere like West Wycombe needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Before we arrive
- Clear items away from the joints we are working on
- Mention any sign-in or site rules at work premises
- Plan for the work area to be out of bounds to pets and children
