We take care not to mark the stone while raking out the old mastic.
Sash and case windows
A sash window’s box frame sits in the masonry opening. The gap round it is pointed with sand mastic.
Sand mastic in Felderland, done properly
Sand mastic doesn’t last for ever, leaving gaps round the window. We rake it out and renew it and tidies the surround. We’re often asked to deal with draughts and rain around sash boxes and gaps round a timber door in stone or brick, on stone surrounds, tenement windows and period & listed homes.
Outdoor sealant needs dry, clean surfaces, so work on frames around Felderland is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
All our work comes with our one-year guarantee.

Felderland homes and the weather
Felderland is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. With historic houses such as Goodnestone Park (about 4.7 miles west) nearby, there’s older building stock in the area around Felderland as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as Sandwich Technology School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Church of St Peter and St Paul, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

For rail, the closest station is Sandwich station, roughly 1 mile north-east of the centre.

Why it’s worth doing now in Felderland
An open joint round the frame lets weather in. Left, water can reach the timber and the wall, so dealing with it now protects both. In a small place like Felderland, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and give you a clear price before work begins.

How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a single window, longer for several, and the area is left clean. Somewhere like Felderland needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Tell us if parking is tricky
- Move anything stored near the joints
Getting a quote
We quote each job on its own, so the first step is telling us about yours. Simply ring 0345 464 0079 or drop us an email and describe the job.
Advice
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep sills and gutters clear so water drains away
- Leave the new mastic unpainted
- Do not run silicone over sand mastic
- Go gently near the mastic when preparing windows
Don’t touch or press the mastic while it hardens. It forms a skin fairly soon but needs longer to fully harden.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
How we quote for sand mastic
We do not publish a price list, because no two jobs are the same. The quote depends on:
- Any working-time requirements on site
- Mould in or behind the old joints
- The type of sealant required
- How easy the joints are to reach
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.
What to tell us for a quote
You do not need to know the technical terms. Just tell us:
- Any previous sealing or DIY work
- How many joints, rooms or windows are involved
- A few pictures by email, if you can
- What’s wrong with the joints now
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. Whenever you are ready, call 0345 464 0079 or send us an email.
Can I do it myself?
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.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Common questions in Felderland
Does the coastal weather in Felderland affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Do you work for landlords with property near Sandwich station?
Yes. We work for landlords and letting agents as well as homeowners. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
Where is Mr Mastic based?
We’re based in Crawley, and we cover South East England, London and all of Scotland.
Which is right for my windows, sand mastic or modern sealant?
Sand mastic normally suits period timber windows best. Modern frames normally suit a flexible sealant, and we’ll explain why.
What information do you need?
A short description and the location, plus pictures if you have them. We’ll ask anything else we need to know.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator.
How do I get a quote for sand mastic in Felderland?
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.
Common problems we fix in Felderland
Paint, silicone or cement used over old mastic causes problems. They do not move with the timber, and they normally need raking out.
Most people get in touch when they notice one of these:
- Draughty sash windows at the surround
- Patchy fillers round a sash window
- Gaps between timber frames and stone or brick
- A silicone bead on a sash window that spoils the look
Rented homes near Sandwich station change hands often, and any sash windows need sound mastic to keep draughts and rain out.
