When it is not the sealant
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Loose or hollow render, which needs re-rendering
- Rising or penetrating damp from elsewhere in the wall
- Cracked brickwork or render that needs a builder or plasterer

External mastic for homes and businesses in Poffley End
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We take the old material out and do it properly. Typical jobs include damp patches traced to an open external joint and sealant that has lost its bond to the brick or render, across render & cladding joints, concrete & block and joints between brick and frames.
Outside joints can only be sealed when they’re dry, so work in Poffley End is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
Big or small, you get the same one-year guarantee.

Outside joints around Poffley End
Historic houses like Minster Lovell Hall (about 2.2 miles west) are a reminder that the area around Poffley End 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. 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.
Letting a property close to Finstock station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you live in an older home near Church of St John the Evangelist, older walls, gutters and the joints where extensions meet them need a flexible sealant. If you look after a building such as Hailey Church of England Primary School, its movement joints, gutters and trims need looking after like any other building’s.

What the job involves on each surface
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
Cladding and façade panels
Cladding and façade panels are normally separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.

How do I get a quote for external mastic in Poffley End?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
Why act early in Poffley End
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. Older cottages and farmhouses around Poffley End can have timber 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. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The process
Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to several days, depending on the building. In a small place like Poffley End, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Mention any sign-in or site rules at work premises
- Let us know about earlier repairs to the joints
- Move anything stored near the joints

Related advice
Keeping the joints in good condition
After the cure time, these simple habits help:
- Keep soil, plants and ivy away from the joints
- Make sure movement joints are not pointed over
- Point out the joints to other trades
- Have failed joints looked at early
Only paint over the joint if we have confirmed the sealant can take paint. Paint can crack on a flexible joint, and paint can crack as the joint moves.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
