Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
In hotels, rooms out of use cost money, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
Sand mastic in Shalfleet
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. We work on timber door frames, stone surrounds and tenement windows, and common reasons people get in touch are weathered mastic on the most exposed windows and modern sealant on a period surround.
Homes in small places like Shalfleet often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

How it works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to a full day, depending on how many windows and we leave things clean and tidy. Somewhere as small as Shalfleet, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive
- Clear the area around the work

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Have rotten timber repaired before new mastic goes in
- Ask the planning authority about consent for listed or conservation-area homes
- Don’t paint over the new mastic
- Keep sills and gutters clear so water drains away
Leave the new mastic unpainted, as traditional guidance advises. Ask us before any decorating around it.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
Frames and glazing around Shalfleet
Shalfleet is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Shalfleet Church of England Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Church of St. Michael the Archangel, the joint between an old wall and a newer frame is normally the first place rain gets in.

Your questions about sand mastic in Shalfleet
Can you do sand mastic in Shalfleet?
Yes. We work across London and the South East, and Shalfleet is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear price.
Does the coastal weather in Shalfleet affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or send us an email.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we’re done.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Which is right for my windows, sand mastic or modern sealant?
We’ll help you decide. Period homes often look best with sand mastic and newer frames suit modern sealant.
What else we do in Shalfleet
DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
What the job involves on each surface
Sash and case windows
Most of our sand mastic work is on sash windows. Each joint round the box is raked out and renewed.
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. We renew it the same way as on windows.
Why deal with it now?
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in, and renewing the mastic closes them. Where a wall is exposed, as many are in small places like Shalfleet, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Doing several joints on one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.
