External mastic for homes and businesses in Thursley
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. We’re often asked to deal with brick movement joints where the sealant has split and gaps where render, brick and frames meet, across brickwork movement joints, façade panels and concrete & block.
In a village or hamlet like Thursley, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
Whatever the size of the job, it’s backed by our one-year guarantee in Thursley and across Surrey.

What happens if it’s left?
A failed movement joint lets water into the wall, behind render and cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. Around Thursley, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.

External mastic in Thursley: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Church of St Michael and All Angels, an extension built onto an older house moves differently, and the joint between them takes the strain.

Surface by surface
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. Where one has been mortared, we cut it out and reseal it with sealant where it can be done safely.
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap.
How the visit works
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a few hours to a few days, depending on the length of joint and the access, depending on the amount of work. In a small place like Thursley, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Tell us if parking is tricky
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints

FAQs for Thursley
Can you do external mastic in Thursley?
Yes. Our work covers London and the South East, and Thursley is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear quote.
Is Thursley within the area you cover?
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.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses and we’re fully insured.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
What does external mastic cost?
It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or email us with a short description of the job.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What we’re called out for in Thursley
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.
The problems people normally mention when they call include:
- Brick movement joints where the sealant has split
- Joints where the bead has come unstuck
- Cracked joints where brick meets render or frames
- Moss and dirt in joints with no sealant left
Rented homes near Witley station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
What your quote should include
- Which sealant they’ll use, and why
- Whether they seal over old material or remove it
- Who does the work, and how experienced they are
- Which colour the sealant will be
