Sand mastic in Holton St Mary
Silicone on a period window often looks wrong and doesn’t suit the building. Sand mastic is the traditional choice, and we can replace one with the other. We work on period & listed homes, stone surrounds and tenement windows, and the jobs we see most are failed mastic on an exposed elevation and gaps where the frame meets the masonry.
Homes in small places like Holton St Mary 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.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Why act early in Holton St Mary
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and finishes neatly against the masonry. Where a wall is exposed, as many are in small places like Holton St Mary, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, phone 0345 464 0079 or email us and we will give you an honest view and a quote.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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.
Sand mastic in Holton St Mary: local notes
With historic houses such as Castle House (about 2.9 miles south) nearby, there’s older building stock in the area around Holton St Mary as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. 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.
Letting a property close to Manningtree station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. In the older streets around Church of St Mary, the joint between an old wall and a newer frame is usually the first place rain gets in.

Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.

Yes. We’re approved under the ARBOMaster scheme.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
When will the new mastic be hard?
A skin forms quite soon, but full hardening takes longer. We will explain what to expect before we leave.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
