External Mastic in Woodchurch
External mastic in Woodchurch from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.

What we’re called out for in Woodchurch
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
The problems people normally mention when they call are:
- Panel joints letting water in
- Brick movement joints where the sealant has split
- Hard, crazed mastic that has stopped moving
- Moss and dirt in joints with no sealant left
Homes close to Parish Church of All Saints include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

External mastic for homes and businesses in Woodchurch
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. We are often asked to deal with joints with sealant missing in places and hard, crazed mastic that has stopped moving, on brickwork movement joints, copings & trims and joints between brick and frames.
Around Woodchurch, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.

What the job involves on each surface
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. The sealant is chosen with that in mind.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so the sealant in it must stay soft and stretchy.
What external mastic looks like in Woodchurch
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Smallhythe Place (about 4.2 miles south-west) are a reminder that the area around Woodchurch has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Letting a property close to Appledore (Kent) station? Then outside joints that have cracked can let damp into a rental, so check them between lets. If you look after a building such as Woodchurch Church of England Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Why deal with it now?
Water gets in through a failed movement joint. Dealing with it early keeps the repair to the joint, instead of the wall and finishes around it. Where a wall is exposed, as many are in small places like Woodchurch, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

How the visit works
The work is kept neat and contained to the area we’re working on. The job usually takes a few hours to a few days, depending on the length of joint and the access, and we explain the cure time before we leave. In a small place like Woodchurch, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any previous sealing or DIY attempts

Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
What do you put in the joint?

Do you have insurance?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Honest limits
We’d rather tell you now than do work that will not last, so these are the limits:
- Walls that need new movement joints cut into them
- Subsidence or other structural problems
- Damp that is not coming from the joint
