Sand Mastic in Molesey

- Tired mastic found when preparing windows for paint
About our sand mastic in Molesey
A silicone bead around a sash window can look out of place and doesn’t suit the building. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. We work on sash and case windows, timber door frames and stone surrounds, and common reasons people get in touch are mastic worn away on windows facing the weather and old cement repairs round a window that have failed.
In smaller places like Molesey, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
Big or small, it’s backed by our one-year guarantee in Molesey and across Surrey.

Signs you need sand mastic in Molesey
Age is the main cause. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
These are the problems we are asked about most:
- A silicone bead on a sash window that spoils the look
- Patchy fillers round a sash window
- Mastic worn away on windows facing the weather
- Mastic dropping out of the joint
If you let a flat or house near Hampton Court station, any sash windows need sound mastic to keep draughts and rain out.

Different surfaces, different methods

Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.

Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Molesey: your questions answered
Do you cover smaller places like Molesey?
Yes, Molesey is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Hampton Court station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Is sand mastic better than silicone for my windows?
Sand mastic generally suits period timber windows best. Modern frames normally suit a flexible sealant, and we’ll explain why.
Where are you based?
Mr Mastic is based in Crawley. We cover Molesey and the rest of Surrey.
What’s sand mastic made of?
It’s sand mixed with a linseed-oil-based binder, used between timber frames and stone or brick.
How do I get a quote for sand mastic in Molesey?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Can I paint the new mastic?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures.
Windows and doors in Molesey
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Hampton Court Palace (about 0.9 miles north-east) are a reminder that the area around Molesey 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.
In the older streets around Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as The Orchard Infant School, the mastic around its windows and doors needs looking after like any other building’s.
Molesey is about 6 miles west of Wimbledon, in Surrey. Jobs in Molesey get the same care as everywhere else we work: old sealant removed completely, careful preparation and a one-year guarantee.

What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from a few hours to a full day, depending on how many windows. Parking around Molesey is generally 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.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
How to prepare
- Clear items away from the joints we are working on
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Avoid heavy scraping on the mastic joint
- Leave the new mastic unpainted
- Sort the mastic before the decorators arrive
- Ask the planning authority about consent for listed or conservation-area homes
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.
