Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Thatcham station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you look after a building such as Cheam School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

External mastic for homes and businesses in Plastow Green
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a matching colour. If you’re dealing with sealant pulling away from one side of the joint and gaps where render, brick and frames meet, we can put it right, whatever the surface.
Somewhere as small as Plastow Green, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.

Should I try it myself first?
If you’ve already had a go yourself, that is fine. We cut it out and start again.
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.
How the visit works
The work is kept neat and contained to the joints we are treating, so you can get on with your day. The job generally takes anything from a few hours to several days, depending on the building, and we tell you how long to leave it before we go. For a village or hamlet like Plastow Green, 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.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before
- Mention any leaks or damp you’ve noticed

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Keep high-pressure jets off the joints
- Clear growth from the base of walls and joints
- Check external joints each spring
- Act on the first splits you see
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges and let water in behind.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
What we cannot put right
Some problems need a builder, plumber or other trade rather than us:
- Cracking across the wall rather than at a joint
- Movement that’s more than a sealant joint can take
- Rising or penetrating damp from elsewhere in the wall
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before you book.

Signs you need external mastic in Plastow Green
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
These are the problems we are asked about most:
- Leaking joints around cladding and façade panels
- Damp patches traced to an open external joint
- Brick movement joints where the sealant has split
- Weathered mastic that no longer stretches
In the older streets around Church of St Paul, older walls, gutters and the joints where extensions meet them need a flexible sealant.
What to look for in a quote
- How the surfaces are prepared before sealing
- Are they insured?
- Who does the work, and how experienced they are
- Whether all the old sealant comes out first

FAQs for Plastow Green
Do you work for landlords with property near Thatcham station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.

What is backing rod for?
The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides, which would stop it stretching.
Can I add another job to the visit?
Yes. Just list everything you need and you’ll get one quote.
Why is there a gap in my brick wall?
Brickwork, render and cladding all move a little, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Can you match the colour of my brickwork?
The aim is a neat, even joint in a colour that suits the wall. We’ll talk through colour options before work begins, matched as closely as the range allows.
Do you have insurance?
Yes. We’re fully insured.
