How we handle sand mastic in Burton End
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. We’re often asked to deal with tired mastic found when preparing windows for paint and gaps where the frame meets the masonry, across sash and case windows, tenement windows and brick reveals.
Outdoor sealant needs dry, clean surfaces, so work on frames around Burton End is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Every job is covered by a 12-month guarantee, wherever you are in Essex.

Windows and doors in Burton End
With historic houses such as Barrington Hall (about 4.3 miles south) nearby, there’s older building stock in the area around Burton End as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near St Mary the Virgin's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For landlords with property near Stansted Mountfitchet station, older sash windows in a rental need their mastic kept sound to keep the weather out.

- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.

Advice
Why it’s worth doing now in Burton End
New sash windows are a major, costly change and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. In a small place like Burton End, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start.

Signs you need sand mastic in Burton End
Timber swells and shrinks with the weather. The movement cracks the mastic over time.
If you can see any of these, it’s time to have the joints looked at:
- Draughts and rain around sash boxes
- Failed mastic on an exposed elevation
- Patchy fillers round a sash window
- Old sand mastic that has cracked, crumbled or fallen out
Managing a site like Forest Hall School? Then its window and door frames need their mastic kept sound, just like a home’s.

Burton End: your questions answered
I let a flat near Stansted Mountfitchet station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Can you do sand mastic in Burton End?

Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Is sand mastic better than silicone for my windows?
For period timber windows in stone or brick, sand mastic is often the better fit. On modern frames, we’d normally use a flexible sealant.
How long does sand mastic take?
Typically it takes a few hours per window, depending on the condition of the joints. Larger jobs naturally take longer.

We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before work begins.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- Where the property is
- How many joints, rooms or windows are involved
- The type of property
- Any previous sealing or DIY work
There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear price for your job. To get started, call 0345 464 0079 or email us.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
