How we handle sand mastic in Barcombe
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. We rake it out and renew it and tidies the surround. If you are dealing with silicone on a period window that looks wrong and old sand mastic that has cracked, crumbled or fallen out, we can help, on period & listed homes, stone surrounds and tenement windows alike.
Mastic can only go onto a dry, clean joint, so window work in Barcombe is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
You get a 12-month guarantee, the same in Barcombe as everywhere else we work.

How we quote for sand mastic
Call for a quick quote. What matters most is:
- Whether there’s mould to deal with
- The size of the job
- Whether old sealant or filler has to be cut out
- How many areas need sealing
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before work begins, so you know where you stand.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- The problem you’ve noticed
- Access, such as stairs, a lift or height
- Any previous sealing or DIY work
- Pictures of the joints, sent by email
Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we’ll explain what’s involved and give you a clear price.
What happens if it’s left?
Cement-based fillers and modern sealants do not 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 Barcombe, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
What you get with us
- Quality sealants from Arbo and Everbuild
- We leave the area clean and tidy
- 20+ years of sealant experience
- A 12-month guarantee on all work

Frames and glazing around Barcombe
With historic houses such as Glyndebourne (about 3.2 miles south-east) nearby, there’s older building stock in the area around Barcombe as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Barcombe Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Cooksbridge station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Signs you need sand mastic in Barcombe
Shallow joints are a common cause. A thin layer does not hold well, which is why we pack deep voids first and get the depth right.
People usually contact us after spotting something like this:
- Wind and rain getting in round a sash window
- Crumbling sand mastic round a window
- Gaps where the frame meets the masonry
- Cracked mastic round a front door frame
In the older streets around The Parish Church of St Mary, the joint between an old wall and a newer frame is normally the first place rain gets in.

Barcombe questions
Do you cover smaller places like Barcombe?
Yes. Barcombe is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do sand mastic in Barcombe?
Yes. We work across London and the South East, and Barcombe is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear price.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures.
How long will you be here?
It depends on the size of the job, but most jobs take a few hours per window, depending on the condition of the joints. We’ll tell you when we quote.
Can you replace silicone on a period window with sand mastic?
In most cases. The silicone is cut out and the joint cleaned, then point it with sand mastic.
Do you guarantee sand mastic work?
All our work has a one-year guarantee, and we’re fully insured.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or send us an email.
Can new sealant go over the old?
No, it won’t last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
When it is not the sealant
In fairness, there are a few things sealant will not fix:
- Crumbling stone or brickwork round the window
- Timber that has rotted
- Planning or listed building consent (your local planning authority decides)
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before you book.
