How we handle window mastic in Woodhatch
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. We work on patio & French doors, uPVC windows and timber windows & doors, and the jobs we see most are mastic that’s falling out in pieces and whistling draughts around closed windows.
Around Woodhatch, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Why deal with it now?
Draughts and leaks do not always mean new windows. Where the frames are sound, new mastic usually deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we will tell you. In a small place like Woodhatch, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, ring 0345 464 0079 or email us for an honest opinion and a quote.

What else we do in Woodhatch
Different surfaces, different methods
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. Each is cleaned, backed where deep and resealed.
Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What happens on the day
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes anything from an hour or two to a full day, depending on how many frames there are, including the tidy-up. Somewhere like Woodhatch needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Mention any parking rules near the property
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises

Looking after it afterwards
After the cure time, these simple habits help:
- Repaint timber before it’s bare
- Make sure the drainage slots are not blocked
- Look round the frames every year or so
- Use gentle cleaners on frames and sealant
Check the drainage slots in the frames aren’t blocked, so water can run away instead of sitting against the joint.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
