About our external mastic in Burkham
On houses, flats and commercial buildings across Burkham, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean joint faces and the right depth. If you have leaking joints around cladding and façade panels and joints pointed up with cement by mistake, we can help, on concrete & block, façade panels and joints between brick and frames alike.
Around Burkham, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water normally gets in, and they need the right sealant at the right depth.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

Burkham buildings and the weather
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Hall Place (about 1.9 miles south) are a reminder that the area around Burkham has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.

The process
We keep the work tidy and contained to the area we are working on, so you can carry on as normal. The job normally takes a few hours for a handful of joints, longer for a whole elevation, and we explain the cure time before we leave. Somewhere as small as Burkham, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by walking round the building and agreeing the joints and the access.
- 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.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Mention any parking rules near the property
- Keep children and pets away from the work area
- Mention any sign-in or site rules at work premises

Related advice
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Wash walls gently around the sealant
- Keep soil, plants and ivy away from the joints
- Have failed joints looked at early
- Walk round the building once a year and look at the joints
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead and let water in behind.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage.

Why act early in Burkham
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. In a small place like Burkham, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.

Different surfaces, different methods
Render joints
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out and helps it last.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so its sealant has to stay flexible.
What sealant work cannot fix
To be straight with you, some problems need a different trade:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Render that is blown, hollow or coming away
- Movement that’s more than a sealant joint can take
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before booking.
Surfaces we seal
- Concrete & block
- Brickwork movement joints
- Copings & trims
- Render & cladding joints
- Joints between brick and frames
- Façade panels
Signs you need external mastic in Burkham
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
If you can see any of these, it’s time to have the joints looked at:
- Old sealant gone brittle and cracked
- Joints with sealant missing in places
- Sealant pulling away from one side of the joint
- Movement joints filled with mortar instead of sealant
Rented homes near Alton station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.
