Window Mastic in East Malling
Problem with your window and door frames in East Malling? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Mastic that has split away from the wall
- Draughty joints inside around the window
- Sealant in the wrong colour for the frame
What happens if it’s left?
Choosing the product is half the job. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. In an older home around East Malling, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What you get with us
- White, clear, grey or coloured to suit, where the product allows
- Every job guaranteed for a year
- Full insurance on every job
- ARBOMaster approved applicator

Window mastic in East Malling
Frames and walls don’t move together. 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. Typical jobs include hard, cracked sealant around windows and cracked sealant at the sill ends, across uPVC windows, window sills and aluminium frames.
Many houses in smaller places like East Malling have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

East Malling homes and the weather
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. With historic houses such as Starkey Castle (about 4.9 miles north) nearby, there’s older building stock in the area around East Malling as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as St James the Great Academy, larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Church of St James, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

We work for landlords and agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
How to look after the new joints
After the cure time, these simple habits help:
- Wash the frames with mild soapy water
- Avoid harsh chemicals near the mastic
- Air rooms to keep condensation down around windows
- Keep drainage slots and sill grooves clear
Try not to touch the new joint while it cures, following the cure time we give you. Keep jet washers away from the frames.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and a cold room gets colder. Resealing closes it.
Common problems we fix in East Malling
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, while a joint packed solid cannot stretch. Backing rod sets the right depth.
If you can see any of these, it’s time to have the joints looked at:
- Cracked internal joints between frame and plaster
- Gaps where the sill meets the wall
- Mastic that is falling out in pieces
- Hard, cracked sealant around windows
Letting a property close to East Malling station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Also in East Malling
Different surfaces, different methods
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.
How it works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of frames, longer for a whole house. In a smaller place like East Malling, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Mention any sign-in or site rules at work premises
- Try not to wet indoor joints just before the visit
- Tell us about any previous sealing or DIY attempts
