Common problems we fix in Potter's Green
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
These are the problems we are asked about most:
- Damp patches on the reveal after heavy rain
- Old mastic that has gone black or come away
- Mastic that has split away from the wall
- White mastic on grey or black frames
Rented homes near Buxted station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

What the job involves on each surface
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. It comes out, deep gaps get backing rod and the joint is resealed.
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We seal the frame and let you know about anything else.
How the visit works
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes most of a day for a typical house, less for a few frames. Somewhere as small as Potter's Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- 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.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Move anything stored near the joints
- Keep children and pets away from the work area

Will there be a smell?
There can be a smell while the sealant cures. Ventilation helps.
Can you seal the gap between the frame and the plaster indoors?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.

Can I add another job to the visit?
Of course. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.

Yes. White, brown, anthracite grey, black and clear sealants are all available.

What affects the quote in Potter's Green
You’ll get a clear quote before work begins. It takes into account:
- Whether the work is at height
- The size of the job
- The old material and how stubborn it is
- The number of rooms or windows
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What to tell us for a quote
Before you ask for a quote, have a think about:
- Photos by email, if that is easy
- If someone has resealed it before
- Whether it’s a home or a business
- The address or postcode of the job
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
Work for landlords, hotels and businesses
We also work for property managers and facilities teams. We can quote a run of properties together.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Keep paint off silicone joints
- Avoid blasting the frames with a pressure washer
- Wash the frames with mild soapy water
- Clear any debris from frame drain holes
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak.
Leaks normally 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.
Window mastic in Potter's Green: local notes
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Buxted CofE Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near Church of St Mary the Virgin, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
