Sand mastic in Snagshall
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. Renewing it closes the gap so the surround looks right again. If you’re dealing with tired mastic found when preparing windows for paint and mastic worn away on windows facing the weather, we can put it right.
Outdoor sealant needs dry, clean surfaces, so work on frames around Snagshall is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
You are covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

What sand mastic looks like in Snagshall
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Great Dixter (about 2.2 miles east) nearby, there’s older building stock in the area around Snagshall as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For landlords with property near Robertsbridge station, cracked sand mastic around sash windows lets in the draughts tenants complain about. If you live in an older home near The Parish Church of St James, the joint between an old wall and a newer frame is usually the first place rain gets in.

What we are called out for in Snagshall
Sand mastic slowly weathers. It dries out, cracks and loses its grip from the frame or the masonry.
The problems people normally mention when they call include:
- Patchy fillers round a sash window
- Crumbling sand mastic round a window
- Mastic round period door frames that has failed
- Gaps between timber frames and stone or brick
Managing a site like Bodiam Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Why act early in Snagshall
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. In a small place like Snagshall, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

How it works
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the work takes a few hours per window, depending on the condition of the joints for a typical job. In a small place like Snagshall, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- 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.

Landlord and commercial work in Snagshall
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
What affects the cost of sand mastic
Jobs vary more than people expect. The main factors:
- How many rooms, windows or areas are involved
- Any mould that needs treating
- Which sealant suits the joint
- The size of the job
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.
What we need to know
Photos by email are helpful but not essential. Please mention:
- What’s wrong with the joints now
- The rough size of the job
- Where the property is
- Whether it’s a home or a business
We quote each job on its own. Simply call 0345 464 0079 or email us and describe the job.
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Keep sills and gutters clear so water drains away
- Find out about consent before window work on a listed home
- Don’t paint over the new mastic
- Do not run silicone over sand mastic
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.
