How we handle window mastic in Kingston
There are two joints on most windows. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. Typical jobs include whistling draughts around closed windows and old mastic that has gone black or come away, on timber windows & doors, window sills and composite doors.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
All our work is covered by our 12-month guarantee.

What we are called out for in Kingston
Mastic ages in the weather. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.
Any of these means the joints need attention:
- Mastic that’s falling out in pieces
- Draughts coming in around windows and doors
- Water coming in at the bottom corners of a door
- Cracked or shrunken mastic around the frame
Rented homes near North Berwick station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

How the job changes by surface
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. It comes out, deep gaps get backing rod and the joint is resealed.
Landlords, agents and businesses in Kingston
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
Windows and doors in Kingston
Kingston is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
For site and facilities teams at buildings such as North Berwick High School, its window and door frames need their mastic kept sound, just like a home’s.

What affects the cost of window mastic
We don’t publish a price list. What we look at:
- The size of the job
- How many areas need sealing
- Whether the work is at height
- When we can work, for business premises
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What we need to know
To help us quote quickly, please include:
- Any access issues, like height or stairs
- The type of property
- What’s wrong with the joints now
- Pictures of the joints, sent by email
Getting a quote is simple: let us know the job and the location. A few pictures by email make the job easier to understand, and we’ll take it from there.
How to look after the new joints
To keep the joints looking good and working properly:
- Ventilate rooms so frames do not stay wet inside
- Don’t aim a pressure washer at the joints
- Keep paint off silicone joints
- Wash the frames with mild soapy water
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
Honest limits
To be straight with you, some problems need a different trade:
- Worn gaskets, brush seals or a door that has dropped
- Soft or decayed wood in the frame
- A sash or casement that won’t close properly
If you’re not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer before you book.
