What happens on the day
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and tidy away. It normally takes anything from a few hours to several days, depending on the building. Somewhere as small as Warnborough Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Mention if the joints have been sealed before
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks

Walls and rooflines in Warnborough Green
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Robert May's School, its movement joints, gutters and trims need looking after like any other building’s. For an older house near a landmark such as Church of St Mary the Virgin, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Can I do it myself?
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 does not work out, we can still put it right.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Point out the joints to other trades
- Deal with leaking gutters that soak the joints below
- Avoid pressure-washing directly into sealant joints
- Check external joints each spring
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead over time.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
What the job involves on each surface
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.
Joints between dissimilar materials
Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.
Why deal with it now?
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. Older cottages and farmhouses around Warnborough Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

What we’re called out for in Warnborough Green
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
Most people get in touch when they notice one of these:
- Cracked joints where brick meets render or frames
- Weathered mastic that no longer stretches
- Brick movement joints where the sealant has split
- Leaking joints around cladding and façade panels
Rented homes near Hook station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
What to look for in a quote
- What insurance they hold
- Whether you can choose the colour
- Whether all the old sealant comes out first
- When the joint can take water or movement
