Window mastic in Boughton Malherbe, done properly
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. If the draught is through the window seals instead, we will tell you. Typical jobs include old mastic that has gone black or come away and cracked sealant at the sill ends, across composite doors, aluminium frames and timber windows & doors.
Around Boughton Malherbe, 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.
There’s a 12-month guarantee on every job, large or small.

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

The process
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours for a handful of frames, longer for a whole house, including the tidy-up. Somewhere like Boughton Malherbe needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints
- Mention any leaks or damp you’ve noticed

Windows and doors in Boughton Malherbe
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Leeds Castle (about 3.6 miles north-west) nearby, there’s older building stock in the area around Boughton Malherbe as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you live in an older home near Church of St Nicholas, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Rented homes near Lenham station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Managing a site like Platts Heath Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

What sealant work can’t fix
We will always be straight with you, so here’s what new sealant won’t do:
- Soft or decayed wood in the frame
- Damp coming through the wall itself rather than the frame joint
- Faulty window hardware
If in doubt, call 0345 464 0079 or email us and we will say what we think.
Joints and surfaces we work on
- Window sills
- Aluminium frames
- Timber windows & doors
- Patio & French doors
- uPVC windows
- Composite doors
Why deal with it now?
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. Where a wall is exposed, as many are in small places like Boughton Malherbe, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Leaving a failed joint usually makes the job bigger, not smaller. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

Surface by surface
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.
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Avoid harsh chemicals near the mastic
- Paint up to the joint, not over it
- Do not aim a pressure washer at the joints
- Keep drainage slots and sill grooves clear
Try not to touch the new joint while it cures, for as long as we advise. Keep jet washers away from the frames.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
