Sand mastic for homes and businesses in Malden Rushett
Sand mastic doesn’t last for ever, leaving gaps round the window. Renewing it closes the gap and tidies the surround. We work on tenement windows, timber door frames and brick reveals, and common reasons people get in touch are gaps round a timber door in stone or brick and draughty sash windows at the surround.
London has a lot of flats and conversions, where windows are often on upper floors. In a converted house or block, the lease normally says who is responsible for the windows, so it’s worth checking before booking.
All our work is covered by a one-year guarantee, wherever you are in Greater London.

Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What else we do in Malden Rushett
Your questions about sand mastic in Malden Rushett
Is parking an issue for sand mastic in Malden Rushett?
Parking in Malden Rushett, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Is Malden Rushett in your area for sand mastic?
Yes. Our work covers London and the South East, and Malden Rushett is part of that. You can call 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear price.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Is consent needed for window work on a listed home?
Yes, it’s worth checking. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all.
What’s sand mastic made of?
Sand mastic is a traditional material for pointing round windows and doors. It combines sand with a linseed-oil-based binder.
How long does sand mastic take to go off?
Not straight away. The skin forms first, and the full set comes later, and we’ll tell you what to expect.
Malden Rushett homes and the weather
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking.
Malden Rushett is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. Rented homes near Chessington South station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.
Malden Rushett is about 2 miles north of Ashtead, in Greater London. Every kind of property in Malden Rushett is covered for sand mastic. Every job comes with our 12-month guarantee. We cover 764 towns and villages across Greater London. We also work in London, around 15 miles away.

Landlord and commercial work in Malden Rushett
In hotels, rooms out of use cost money, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
Failed sealant is one of the commonest items on a check-out report. Several properties can be quoted together.
Why deal with it now?
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

Different surfaces, different methods
Period and listed homes
Period homes look their best with traditional materials.
Stone surrounds
Stone openings are rarely perfectly straight, so the joint varies in width. We shape it by hand to follow the stone.
What we cannot put right
To be straight with you, there are a few things sealant will not fix:
- Damaged stone surrounds
- Decisions on consent for listed homes
- Sash cords, weights and draught-proofing of the sashes
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Period & listed homes
- Tenement windows
- Brick reveals
- Timber door frames
- Sash and case windows
- Stone surrounds
Common problems we fix in Malden Rushett
Rain on the window surround works into any crack and loosens it further. Windows facing the weather tend to go first.
It’s worth asking for a quote if you see:
- Window mastic to renew ahead of painting
- Gaps between timber frames and stone or brick
- Wind and rain getting in round a sash window
- Weathered mastic on the most exposed windows
Fitznells Manor, about 3.1 miles east, is one of the historic houses in the wider area around Malden Rushett, and older homes nearby need a sealant that suits their walls.
Questions to ask before you book
- How the colour is chosen
- What preparation is included
- What happens if the job turns out different
- The length of the guarantee
What we do, step by step
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It usually takes anything from a few hours to a full day, depending on how many windows. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Malden Rushett. It helps if you can point us to a visitor permit or a bay close to the door.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before
