Sand mastic in Sutton Valence
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. Typical jobs include old sand mastic that has cracked, crumbled or fallen out and open joints round the window box, across sash and case windows, timber door frames and stone surrounds.
Homes in small places like Sutton Valence often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

When to call us in Sutton Valence
Rain on the window surround works into any crack and pushes it out. Exposed elevations normally fail first.
Keep an eye out for these signs:
- Modern sealant on a period surround
- Mastic dropping out of the joint
- Gaps between timber frames and stone or brick
- Patchy fillers round a sash window
Managing a site like Sutton Valence Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
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 does not work out, we can still put it right.

Questions from Sutton Valence
Do you cover smaller places like Sutton Valence?
Yes, Sutton Valence is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is Sutton Valence in your area for sand mastic?
Yes, Sutton Valence is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or email us.
I rent my home. Can I book you?
Yes. Check with your landlord; we can send the quote to them too.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Will the old sealant be removed?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.

Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Why act early in Sutton Valence
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 Sutton Valence, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.
What you get with us
- Over 20 years’ experience
- A 12-month guarantee on all work
- Approved under the ARBOMaster scheme

Sutton Valence homes and the weather
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. Historic houses like Stoneacre (about 2.8 miles north) are a reminder that the area around Sutton Valence has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For an older house near a landmark such as Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Letting a property close to Staplehurst station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.

How it works
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a single window, longer for several.

We bring what the job needs, so it can be finished in one trip where possible.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic is not too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work
- Clear items away from the joints we are working on

Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Ask the planning authority about consent for listed or conservation-area homes
- Avoid patching sand mastic with silicone
- Avoid heavy scraping on the mastic joint
- Have rotten timber repaired before new mastic goes in
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
