Sand mastic in Weston Green, done properly
Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties where a modern sealant bead would stand out. If you have cracked mastic round a front door frame and draughts and rain around sash boxes, we can put it right, whatever the surface.
Homes in small places like Weston Green often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Whatever the size of the job, it’s backed by our 12-month guarantee in Weston Green and across Surrey.

What affects the cost of sand mastic
We do not publish a price list. The quote depends on:
- How much old sealant there is and how hard it is to remove
- Any working-time requirements on site
- The number of rooms or windows
- How easy the joints are to reach
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What we need to know
When you call or email, these details help:
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it has been sealed before
- Pictures of the joints, sent by email
- Where the property is
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we’ll talk you through the work before giving you a price.

How it works
At the end, we look at the finished work together and tell you how long to leave it. The visit itself normally takes a few hours per window, depending on the condition of the joints, depending on how much there is to do. Somewhere as small as Weston Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- Large voids are packed out first, so the mastic isn’t too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- For business premises, tell us about site rules or sign-in
- Tell us about access, such as stairs, a lift or high-level joints

Landlord and commercial work in Weston Green
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll quote.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Why deal with it now?
New mastic over crumbling mastic will not hold. We remove the loose material first so the new mastic stays put. In a small place like Weston Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.

Do you need sand mastic in Weston Green?
Over the years, sand mastic weathers. It dries out, cracks and loses its grip from the frame or the masonry.
Any of these means the joints need attention:
- Gaps round a timber door in stone or brick
- Tired mastic found when preparing windows for paint
- Gaps where the frame meets the masonry
- Draughty sash windows at the surround
For site and facilities teams at buildings such as Esher College, its window and door frames need their mastic kept sound, just like a home’s.
What your quote should include
- The length of the guarantee
- Which sealant they’ll use, and why
- What the cure time is
- Whether all the old sealant comes out first

What sand mastic looks like in Weston Green

In older buildings, 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
