About our external mastic in Mickleham
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two where a rigid filler would soon crack. If you’re dealing with rigid filler in a joint that should flex and joints with sealant missing in places, we can help, whatever the surface.
External sealant needs dry, clean surfaces, so work around Mickleham is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracked brickwork or render that needs a builder or plasterer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.
What we seal
- Render & cladding joints
- Concrete & block
- Copings & trims
- Façade panels
- Brickwork movement joints
- Joints between brick and frames
DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Quotes for external mastic in Mickleham
There’s no set price list, because jobs vary so much. What we look at:
- The number and length of the joints
- Access and height
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Whether it has been sealed before
- Where the job is, and your postcode
- Any access issues, like height or stairs
- Photos by email, if that’s easy
We don’t publish a price list. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or email us.
Do you need external mastic in Mickleham?
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
People usually contact us after spotting one of these:
- Gaps where render, brick and frames meet
- Weeds or debris growing in open joints
- Hard, crazed mastic that has stopped moving
- Joints where the bead has come unstuck
If you look after a building such as St Michael's CofE Aided Infant School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Your questions about external mastic in Mickleham
Can you help a landlord with a rental near Box Hill & Westhumble station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Will you come out to Mickleham?
Yes, Mickleham is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
What colours does the sealant come in?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best so it doesn’t stand out.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Can you seal joints between two different materials?
Yes. Joints between dissimilar materials are a big part of external work. We use a flexible sealant suited to both surfaces with primer where required.
Where are you based?
Our base is in Crawley, and we work across South East England, London and Scotland.
What information do you need?
Let us know what needs doing and where, with pictures by email if possible. If we need more, we’ll ask.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
What we do, step by step
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on the building. In a small place like Mickleham, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Tell us if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive
- Clear items away from the joints we are working on

Leave it or put it right?
Resealing a run of joints in one go is generally better than patching one at a time. Joints of the same age tend to fail together. Where a wall is exposed, as many are in small places like Mickleham, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
What you get with us
- You choose the colour before work begins
- White, clear, grey or another colour, product permitting

What external mastic looks like in Mickleham
With historic houses such as Polesden Lacey (about 2.4 miles west) nearby, there’s older building stock in the area around Mickleham as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. 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.
Homes close to Church of St Michael include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. For landlords with property near Box Hill & Westhumble station, split movement joints are easy to miss on a rental until damp shows inside.
