Window & door mastic in Brattle, Kent
Mastic around window and door frames, sills and patio doors for homes and businesses in Brattle and across Kent. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.

- Mastic that has split away from the wall
How we handle window mastic in Brattle
The new joint doesn’t 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, window sills and timber windows & doors, and the jobs we see most are damp patches on the reveal after heavy rain and sealant in the wrong colour for the frame.
Around Brattle, 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.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or email us.

Brattle: your questions answered
Can you do window mastic in Brattle?

Can you help a landlord with a rental near Appledore (Kent) station?
Yes. We work for letting agents and landlords as well as householders. Just call 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
How much does window mastic cost in Brattle?
Size, access and the old material all affect the cost. Ask us for a quote.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Will there be a smell?
Some sealants have a smell while they cure. Ventilation helps.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Will resealing my frames help with draughts?
If the draught is coming in around the frame, yes. If it’s coming through the window seals, we’ll tell you.
Can you reach windows above the ground floor?
Normally, yes. We plan safe access before the job, so mention the height and anything in the way.
Honest limits
New sealant can’t fix everything, and we will tell you before any work starts. Sealant will not put right:
- Draughts through the window seals rather than the frame
- Damp coming through the wall itself rather than the frame joint
- Broken hinges, locks or handles
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.
Joints and surfaces we work on
- Patio & French doors
- uPVC windows
- Window sills
- Aluminium frames
- Timber windows & doors
- Composite doors
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Aftercare tips
After the cure time, these simple habits help:
- Avoid blasting the frames with a pressure washer
- Keep drainage slots and sill grooves clear
- Keep paint and stain on wooden frames in good order
- Keep solvents and bleach off the sealant
Keep the new mastic undisturbed while it cures, for as long as we advise. Keep jet washers away from the frames.
Leaks generally show up in wet, windy weather, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
What we do, step by step
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. It normally takes most of a day for a typical house, less for a few frames. In a small place like Brattle, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Keep pets and children clear of the area while we work
- For indoor joints, keep the area dry beforehand if you can

Advice
What happens if it’s left?
Working on frames from a ladder with a sealant gun is not easy, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. Older cottages and farmhouses around Brattle can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Why us?
- We agree the colour with you first
- We never seal over old sealant
- Sealant colour chosen to suit
- White, clear, grey or another colour, product permitting
What the job involves on each surface
Window sills
Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. They’re cut out and resealed with exterior sealant.
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.
Common problems we fix in Brattle
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
It’s worth asking for a quote if you see:
- Mastic that’s falling out in pieces
- A bead that does not match the frame
- Mastic that has split away from the wall
- Cracked sealant at the sill ends
For landlords with property near Appledore (Kent) station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Brattle homes and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Smallhythe Place (about 4.1 miles south-west) nearby, there’s older building stock in the area around Brattle 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’s traditional sand mastic.
Managing a site like Woodchurch Church of England Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. Homes close to Parish Church of All Saints include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.
