About our external mastic in Penny Pot
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We strip the joint back and start again. We work on façade panels, concrete & block and copings & trims, and people most often call us about joints with sealant missing in places and rain getting behind render or cladding at a joint.
Around Penny Pot, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water generally gets in.
We stand behind the work with a one-year guarantee.

Why it’s worth doing now in Penny Pot
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost, so the problem grows beyond the joint itself. In a small place like Penny Pot, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Leaving a failed joint usually makes the job bigger, not smaller. If you’re unsure, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.

Common questions in Penny Pot
Will you come out to Penny Pot?
Yes, Penny Pot is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Brookwood station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
How often do external joints need resealing?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Every job carries our 12-month guarantee.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
How long will you be here?
As a guide, most jobs take a few hours for a handful of joints, longer for a whole elevation. Bigger jobs take longer.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Can you seal joints between render and window frames?
Yes. Materials like render, brick, metal and uPVC all move differently, so a flexible sealant is needed where they meet. We choose one that suits both surfaces.
Are you fully insured?
Yes. Full insurance covers our work.
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Check external joints each spring
- Keep soil, plants and ivy away from the joints
- Check the sealant is paintable before painting near it
- Show decorators and builders where the movement joints are
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
Different surfaces, different methods
Render joints
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so its sealant has to stay flexible.
What happens on the day
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the building. In a small place like Penny Pot, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Let us know if you’ve seen damp or leaks
- Mention any sign-in or site rules at work premises

Other services in Penny Pot
Outside joints around Penny Pot
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. Historic houses like Botleys Mansion (about 4.4 miles north-east) are a reminder that the area around Penny Pot has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Schools such as Holy Trinity CofE Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. Letting a property close to Brookwood station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
When to call us in Penny Pot
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it cannot stretch and tears as soon as the joint widens.
It’s worth asking for a quote if you see:
- Leaking joints around cladding and façade panels
- Joints pointed up with cement by mistake
- Water getting into walls through failed joints
- Hard, crazed mastic that has stopped moving
Homes close to Church of St Lawrence include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
