External mastic for homes and businesses in Egham Wick
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant. We work on copings & trims, façade panels and brickwork movement joints, and common reasons people get in touch are movement joints with cracked, split or missing sealant and hard, crazed mastic that has stopped moving.
Around Egham Wick, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.

Why deal with it now?
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render around the joint, so the damage spreads beyond the joint. In a small place like Egham Wick, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.

Egham Wick buildings and the weather
Historic houses like Frogmore House (about 3.6 miles north) are a reminder that the area around Egham Wick has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Church of Saint Simon and Saint Jude, an extension built onto an older house moves differently, and the joint between them takes the strain. Letting a property close to Virginia Water station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. Managing a site like St Cuthbert's Catholic Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Should I try it myself first?
A careful DIYer can reseal a simple joint, 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.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Egham Wick: your questions answered
Can you do external mastic in Egham Wick?
Yes. We work across London and the South East, and Egham Wick is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
Will you come out to Egham Wick?
Yes, we do. 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.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Why is there a gap in my brick wall?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.
Are you insured?
Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or email us.
Will the new joint stand out?
We aim for a joint that suits the wall rather than one that jumps out. We will talk through colour options before work begins, matched as closely as the range allows.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Keep high-pressure jets off the joints
- Get split or bare joints resealed while the damage is small
- Never let anyone fill a movement joint with mortar
- Keep water from gutters off the wall
Do not let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.

- Mould in or behind the old joints
- The old material and how stubborn it is
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of joints, longer for a whole elevation and we leave things clean and tidy.

- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.

- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
