Sand mastic for homes and businesses in Great Maplestead
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. Common call-outs are for modern sealant on a period surround and draughty sash windows at the surround, across period & listed homes, timber door frames and tenement windows.
In a village or hamlet like Great Maplestead, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Each job carries a 12-month guarantee, large or small.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Clear gutters so water does not pour onto the windows
- Avoid patching sand mastic with silicone
- Do not paint over the new mastic
- Avoid heavy scraping on the mastic joint
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.
How it works
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours for a single window, longer for several, depending on the size of the job.

Frames and glazing around Great Maplestead
Historic houses like Hedingham Castle (about 1.6 miles north-west) are a reminder that the area around Great Maplestead has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Church of St Giles, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you look after a building such as St Giles' Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Questions from Great Maplestead
Is sand mastic in Great Maplestead guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Is Great Maplestead within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What’s sand mastic made of?
It’s the traditional filler for the joint round timber windows and doors. It combines sand with a linseed-oil-based binder.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Can landlords and businesses book you?
Yes, we do. We work in homes, commercial premises and hotels, and we’re fully insured.
Do you offer different sealant colours?
In most cases you can choose. We will explain which colours are available.
Should I use sand mastic or silicone?
That depends on your windows. Period windows in stone or brick normally suit sand mastic, while modern frames normally get a flexible sealant.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or drop us an email.

Asking for a quote
There’s no need for technical detail. It helps if you can tell us:

- Whether it has been sealed before

What else we do in Great Maplestead
Why act early in Great Maplestead
Not every filler suits an old window surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. Around Great Maplestead, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or email us and we’ll talk you through it.

Can I do it myself?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
