Sand mastic in Brimpton
Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditionally, sand mastic is left unpainted, so ask us before you decorate. Common call-outs are for tired mastic found when preparing windows for paint and mastic worn away on windows facing the weather, on tenement windows, sash and case windows and period & listed homes.
Outdoor sealant needs dry, clean surfaces, so work on frames around Brimpton is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Big or small, you get the same one-year guarantee.

Questions from Brimpton
Will you come out to Brimpton?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I let a flat near Midgham station. Can you help?
Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. You can ring 0345 464 0079 or email us with the details for a clear quote.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
What should I tell you?
Tell us what needs doing and where. If we need more, we’ll ask.
Is it OK to seal over old sealant?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
How long does sand mastic take to go off?
It forms a skin fairly soon, then hardens over a longer period. The weather and joint depth both affect it.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Landlords, agents and businesses in Brimpton
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Looking after it afterwards
So the new joints stay in good condition:
- Ask us before painting near the mastic
- Check the mastic when you check the paintwork
- Keep modern sealant off the mastic
- Renew mastic before redecorating the windows
Avoid painting over the new mastic, as traditional guidance advises. Ask us before any decorating around it.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
Surface by surface
Stone surrounds
The stone is treated with care when the old mastic comes out.
Tenement and terrace windows
Upper-floor windows need access planning. Let us know the floor and we’ll confirm access.
Why act early in Brimpton
New sash windows are a major, costly change and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. Where a wall is exposed, as many are in small places like Brimpton, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Why us?
- Domestic, commercial and hotel work
- 12-month guarantee on every job
- We never seal over old sealant
- Sanitary silicone with an anti-fungal additive in wet areas

Sand mastic in Brimpton: local notes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near Church of St Peter, the joint between an old wall and a newer frame is generally the first place rain gets in. Letting a property close to Midgham station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. For site and facilities teams at buildings such as Brimpton C.E. Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

How it works
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take anything from a few hours to a full day, depending on how many windows. For a village or hamlet like Brimpton, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Mention any tricky access
- On commercial sites, let us know about site rules
