Sand mastic in Fetcham
We work across Fetcham renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. We work on sash and case windows, tenement windows and brick reveals, and common reasons people get in touch are draughts and rain around sash boxes and weathered mastic on the most exposed windows.
In smaller places like Fetcham, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. Each frame material needs the right sealant against the right wall.
A 12-month guarantee comes as standard, so you’re covered after we have gone.

Sand mastic in Fetcham: 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. Historic houses like Polesden Lacey (about 2.4 miles south) are a reminder that the area around Fetcham has older buildings as well as new. 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.
For landlords with property near Leatherhead station, older sash windows in a rental need their mastic kept sound to keep the weather out. If you live in an older home near Church of St. Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you look after a building such as Oakfield Junior School, its window and door frames need their mastic kept sound, just like a home’s.

How we quote for sand mastic
Every job gets its own quote. This is what makes a difference:
- Whether the work is at height
- Whether old sealant or filler has to be cut out
- The type of sealant required
- The number and length of the joints
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.
Helping us quote
Before you ask for a quote, have a think about:
- If it’s domestic, commercial or a hotel
- What’s wrong with the joints now
- Where the job is, and your postcode
- How we’d reach the joints
Getting a quote is simple: let us know what needs doing and where. A few pictures by email make the job easier to understand.
Leave it or put it right?
Not every filler suits an old window surround. Sand mastic is the like-for-like choice and that can be important for listed homes. In a smaller place like Fetcham, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
The process
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes anything from a few hours to a full day, depending on how many windows. Parking around Fetcham is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit
- Mention any sign-in or site rules at work premises

Fetcham: your questions answered
Is Fetcham in your area for sand mastic?
Yes. Our work covers London and the South East, and Fetcham is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we will send you a clear quote.
I let a flat near Leatherhead station. Can you help?

Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Can sand mastic be painted?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
How long does sand mastic take to go off?
A skin forms quite soon, but full hardening takes longer. We will tell you what to expect for your job.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
