Sand mastic for homes and businesses in Shotgate
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant and we will explain which is best for yours. Common call-outs are for crumbling sand mastic round a window and draughty sash windows at the surround, on sash and case windows, period & listed homes and brick reveals.
Somewhere as small as Shotgate, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Every job comes with our 12-month guarantee, wherever you are in Essex.

Common questions in Shotgate
Is Shotgate within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you do sand mastic in Shotgate?
Yes. We work across London and the South East, and Shotgate is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Where is Mr Mastic based?
We work from Crawley. We cover Shotgate and the rest of Essex.
Is it possible to take out silicone and use sand mastic instead?
Yes, we do this often. The old silicone has to come out completely so the mastic beds in well.
Which is right for my windows, sand mastic or modern sealant?
It depends on the window. Period windows in stone or brick usually suit sand mastic and newer frames generally get a flexible sealant.
Can I choose the sealant colour?
In most cases you can choose. We will explain which colours are available.
Windows and doors in Shotgate
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Beauchamps High School, the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Battlesbridge station? Then any sash windows need sound mastic to keep draughts and rain out.

Common problems we fix in Shotgate
Decorating can disturb tired mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
Keep an eye out for any of the following:
- Gaps round a timber door in stone or brick
- A silicone bead on a sash window that spoils the look
- Gaps between timber frames and stone or brick
- Weathered mastic on the most exposed windows
Homes close to Church of St Nicholas include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Before you book anyone
- When the joint can take water or movement
- What guarantee comes with the work
- Whether they’re fully insured
- Whether you can choose the colour
DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Clear gutters so water does not pour onto the windows
- Ask the planning authority about consent for listed or conservation-area homes
- Get any rot dealt with first
- Leave the new mastic unpainted
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at before trying a quick fix.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens as more mastic falls out.
Surface by surface
Tenement and terrace windows
Where a building is shared, window work may involve neighbours, so check who is responsible first.
Brick reveals
Brick reveals round timber windows are often pointed with sand mastic. It suits older brickwork.
How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours per window, depending on the condition of the joints, and the area is left clean. In a small place like Shotgate, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Tell us about any water getting in
- Keep pets and children clear of the area while we work
- On commercial sites, let us know about site rules
