External mastic in Claygate, done properly
Low-level joints can normally be done from the ground. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. We work on brickwork movement joints, façade panels and copings & trims, and the jobs we see most are panel joints letting water in and gaps where render, brick and frames meet.
Around Claygate, garages, outbuildings and extensions all add to the joints on the outside of a home. Leaks generally start at a gutter end, a garage door frame or where an extension meets the house.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

What we do, step by step
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a handful of joints, longer for a whole elevation. A visit to Claygate is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Mention any parking rules near the property
- Tell us about access, such as stairs, a lift or high-level joints
- Clear the area around the work

Advice
FAQs for Claygate
Can you do external mastic in Claygate?
Yes. Our work covers London and the South East, and Claygate is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear quote.
Is Claygate within the area you cover?
Yes. Claygate is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can landlords and businesses book you?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
How do you reach high-level joints?
It depends on the building. We work on joints that can be reached safely. Tell us about the building and we will confirm what access is needed.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or drop us an email.
Is it OK to fill a movement joint with cement?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. Use a flexible sealant with backing rod.
Is there a guarantee?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
Surface by surface
Render joints
Rendered walls have joints at beads, openings and changes of material. They’re resealed in a sealant that suits the render.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. We reseal them with a low-modulus sealant over backing rod.
Landlords, agents and businesses in Claygate
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
In hotels, rooms out of use cost money, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Check external joints each spring
- Avoid pressure-washing directly into sealant joints
- Make sure movement joints are not pointed over
- Keep soil, plants and ivy away from the joints
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
Claygate buildings and the weather
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as The Homewood (about 2.3 miles west) nearby, there’s older building stock in the area around Claygate as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
Homes close to Church of Holy Trinity include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant. Letting a property close to Claygate station? Then outside joints that have cracked can let damp into a rental, so check them between lets. For site and facilities teams at buildings such as Claygate Primary School, its movement joints, gutters and trims need looking after like any other building’s.

What sealant work can’t fix
New sealant can’t fix everything, and we’d rather say so up front. It won’t solve:
- Cracking across the wall rather than at a joint
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Failed render or damaged cladding panels
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before booking.
What we seal
- Façade panels
- Render & cladding joints
- Concrete & block
- Brickwork movement joints
- Copings & trims
- Joints between brick and frames
Why deal with it now?
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Around Claygate, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and send you a clear quote before we start.

DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
