How we handle sand mastic in Send Marsh
Across Send Marsh, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. We are often asked to deal with open joints round the window box and cracked mastic round a front door frame, on sash and case windows, tenement windows and stone surrounds.
In a village or hamlet like Send Marsh, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
All of our work is guaranteed for twelve months, in Send Marsh and everywhere else we cover.

Quotes for sand mastic in Send Marsh
There’s no set price list, because no two jobs are the same. The quote depends on:
- Any mould that needs treating
- Any working-time requirements on site
- How many areas need sealing
- Whether the work is at height
The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

How the job changes by surface
Sash and case windows
Most of our sand mastic work is on sash windows. We renew the mastic round each box.
Period and listed homes
Many older homes were built with sand mastic round the windows. If your home is listed, ask your local planning authority about consent.
Why deal with it now?
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. Where a wall is exposed, as many are in small places like Send Marsh, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or send us an email.

What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a single window, longer for several and we leave things clean and tidy. Somewhere as small as Send Marsh, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Move anything stored near the joints
- Keep pets and children clear of the area while we work
- Tell us about access, such as stairs, a lift or high-level joints

Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Renew mastic before redecorating the windows
- Check the mastic when you check the paintwork
- Take care around the mastic when scraping paint
- Avoid patching sand mastic with silicone
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What sand mastic looks like in Send Marsh
Historic houses like Clandon Park (about 2.7 miles south) are a reminder that the area around Send Marsh has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Letting a property close to Clandon station? Then older sash windows in a rental need their mastic kept sound to keep the weather out. For site and facilities teams at buildings such as Send CofE Primary School, larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near St William of York, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
