Sand mastic for homes and businesses in St Michaels
Sand mastic doesn’t last for ever and gaps open up round the frame. Renewing it closes the gap and tidies the surround. We work on stone surrounds, tenement windows and timber door frames, and people most often call us about open joints round the window box and mastic worn away on windows facing the weather.
Outdoor sealant needs dry, clean surfaces, so work on frames around St Michaels is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
There’s a 12-month guarantee on every job, large or small.

Sand mastic in St Michaels: local notes
Historic houses like Smallhythe Place (about 3.3 miles south) are a reminder that the area around St Michaels has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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 St Michael's Church of England Primary School, 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 Michael, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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, and the work is guaranteed for a year.
Questions from St Michaels
What guarantee comes with sand mastic in St Michaels?
All our work, in St Michaels and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Will you come out to St Michaels?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Can you quote for more than one area?
Yes. More than one area can go on one quote.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Is it possible to paint over sand mastic?
It’s traditionally left unpainted, which is what traditional guidance recommends. Ask us before decorating.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
Why it’s worth doing now in St Michaels
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new mastic stays put. In a small place like St Michaels, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

What affects the quote in St Michaels
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Which sealant suits the joint
- How many areas need sealing
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
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.
Helping us quote
What to tell us when you ask for a quote:
- The rough size of the job
- Pictures of the joints, sent by email
- Where the job is, and your postcode
- Any access issues, like height or stairs
Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we’ll explain what’s involved and give you a clear price.
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Avoid heavy scraping on the mastic joint
- Ask a joiner to look at soft timber first
- Look over the window mastic once a year
- Ask the planning authority about consent for listed or conservation-area homes
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
How it works
When we arrive, we start by going over the job with you. We protect the surfaces around the joints before we start. The work normally takes a few hours for a single window, longer for several. In a small place like St Michaels, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Getting ready for the visit
- Mention any tricky access
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property

Advice
What the job involves on each surface
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. The gap round it is pointed with sand mastic.
