Sand mastic for homes and businesses in Tollesbury
Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditionally, sand mastic is left unpainted and we’ll advise if you’re redecorating. If you have gaps between timber frames and stone or brick and mastic worn away on windows facing the weather, we can help, on timber door frames, stone surrounds and sash and case windows alike.
Around Tollesbury, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
You’re covered for a year from the day we finish. If anything isn’t right with it, call 0345 464 0079 or drop us an email.

Signs you need sand mastic in Tollesbury
Over the years, sand mastic weathers. It hardens, cracks and starts to come away from the frame or the masonry.
Keep an eye out for these signs:
- Wind and rain getting in round a sash window
- Weathered mastic on the most exposed windows
- Mastic round period door frames that has failed
- Cement or filler used on old window joints that has cracked
Homes close to Church of St Mary the Virgin include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What sand mastic looks like in Tollesbury
Tollesbury is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. 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.
Schools such as Tollesbury School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
Tollesbury is about 7 miles east of Maldon, in Essex.

What affects the quote in Tollesbury
Your quote is based on your job. We look at:
- How many areas need sealing
- Whether old sealant or filler has to be cut out
- Any working-time requirements on site
- How easy the joints are to reach
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we will explain what it covers.
What to tell us for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- If it’s domestic, commercial or a hotel
- Photos by email, if that’s easy
- Any access issues, like height or stairs
- What the problem is, such as mould, gaps, leaks or cracking
We do not publish a price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or email us.
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
We also work for property managers and facilities teams. We can quote a run of properties together, and we’re fully insured.
How the visit works
On the day, we start by going over the job with you. We protect the surfaces around the joints before any work begins. The work generally takes anything from a few hours to a full day, depending on how many windows. Somewhere like Tollesbury needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Before we arrive
- Let us know about parking restrictions
- Keep children and pets away from the work area
- Where the joints are inside, avoid wetting them before we arrive

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Avoid heavy scraping on the mastic joint
- Avoid patching sand mastic with silicone
- Leave the new mastic unpainted
- Plan mastic work ahead of painting
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
When it is not the sealant
Before booking, it’s worth knowing the limits too:
- Sash cords, weights and draught-proofing of the sashes
- Decayed frames that need repair
- Cracked or broken glass
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly.
