External mastic for homes and businesses in Beacon's Bottom
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what access is needed. We are often asked to deal with damp patches traced to an open external joint and moss and dirt in joints with no sealant left, across render & cladding joints, copings & trims and concrete & block.
Somewhere as small as Beacon's Bottom, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or send us an email.

Honest limits
A few problems are outside what sealant work can do:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracking across the wall rather than at a joint
If in doubt, ring 0345 464 0079 or email us and we will say what we think.

What else we do in Beacon's Bottom
What we’re called out for in Beacon's Bottom
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
Keep an eye out for these signs:
- Moss and dirt in joints with no sealant left
- Gaps where render, brick and frames meet
- Joints where the bead has come unstuck
- Old sealant gone brittle and cracked
Rented homes near Saunderton station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

Common questions in Beacon's Bottom
Do you cover smaller places like Beacon's Bottom?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Yes, we work for landlords and agents. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
What do you need from me for a quote?
A short description and the location. If we need more, we’ll ask.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and we clear up when we’re done.
Can I add another job to the visit?
Yes. Just list everything you need and you will get one quote.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used before we leave.
How to look after the new joints
Looking after new joints is easy:
- Check the sealant is paintable before painting near it
- Make sure movement joints aren’t pointed over
- Don’t let climbing plants root in the sealant
- Fix overflowing gutters above sealed joints
Only paint over the joint if we have confirmed the sealant can take paint. Paint can crack on a flexible joint.
Act while the splits are small. At that stage it’s a simple cut out and reseal.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
