External mastic for homes and businesses in Acton
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. We work on façade panels, concrete & block and brickwork movement joints, and people most often call us about weeds or debris growing in open joints and failed sealant between panels on a façade.
Older homes in small places like Acton may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water normally gets in, and they need the right sealant at the right depth.
Our work is backed for twelve months, in Acton and everywhere else we cover.

What external mastic looks like in Acton
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 Smallhythe Place (about 1.5 miles north-west) are a reminder that the area around Acton has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
If you look after a building such as Wittersham Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing. In the older streets around Parish Church of St John the Baptist, an extension built onto an older house moves differently, and the joint between them takes the strain. For landlords with property near Appledore (Kent) station, split movement joints are easy to miss on a rental until damp shows inside.

Why act early in Acton
Running new sealant over the old bead rarely lasts. The new layer cannot bond properly to old, weathered material, so we always take the old sealant out. Around Acton, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

The process
We work through the job in order: protect, prepare, seal, tidy. Typically it takes anything from a few hours to several days, depending on the building and we leave things clean and tidy. Somewhere as small as Acton, access is often the only tricky part. 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.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed
- For indoor joints, keep the area dry beforehand if you can

How the job changes by surface
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. A primer goes on where the product requires one before sealing.
Joints between dissimilar materials
Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.
Common questions in Acton
Is Acton within the area you cover?
Yes. Acton is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.

Yes. Different materials move at different rates, so a flexible sealant is needed where they meet. We choose one that suits both surfaces.

Quotes for external mastic in Acton
Every job gets its own quote. These are the things that affect it:
- How many areas need sealing
- When we can work, for business premises
- Which sealant suits the joint
- How easy the joints are to reach
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first.
Helping us quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- If someone has resealed it before
- Whether it’s a home or a business
- Roughly how big the job is
- The address or postcode of the job
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you’ve already had a go yourself, that is fine. We cut it out and start again.
