A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.

How we handle sand mastic in Shalcombe
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. If you are dealing with gaps round a timber door in stone or brick and draughts and rain around sash boxes, we can put it right.
In a village or hamlet like Shalcombe, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Every job comes with a one-year guarantee.

Sand mastic in Shalcombe: local notes
Shalcombe is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. 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.
In and around Shalcombe, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint. Homes close to St. Mary's Church include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.
Shalcombe is about 6 miles west of Newport, in the Isle of Wight. If you need sand mastic in Shalcombe, it’s easy to get a quote: please ring 0345 464 0079 or drop us an email.

Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Check with your local planning authority if your home is listed
- Keep sills and gutters clear so water drains away
- Go gently near the mastic when preparing windows
- Don’t run silicone over sand mastic
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
Why it’s worth doing now in Shalcombe
Draughts round a sash window are not always the sashes. Open mastic joints round the box can let air in, and renewing the mastic closes them. Older cottages and farmhouses around Shalcombe can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

How the visit works
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours for a single window, longer for several from start to finish. For a village or hamlet like Shalcombe, the journey is planned in advance: 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 start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Where the joints are inside, avoid wetting them before we arrive
- Let us know if you’ve seen damp or leaks

Questions from Shalcombe
Does living near the coast affect sand mastic in Shalcombe?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
Will you come out to Shalcombe?
Yes, we do. 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.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels.
Do I need permission for sand mastic on a listed building?
Yes, it’s worth checking. Your local planning authority can say if consent is needed for work on a listed home or in a conservation area.
How long does sand mastic take?
Typically it takes a few hours for a single window, longer for several. Bigger jobs take longer.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.
When will the new mastic be hard?
Not straight away. It skins first and hardens fully later, and we’ll tell you what to expect.
Can I choose the sealant colour?
We help you choose a colour that suits. The choice depends on the product the joint needs.
How the job changes by surface
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We work on single windows or whole elevations.
