External mastic in Frogham, done properly
Low-level joints can usually be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what’s needed to reach them safely. If you have weeds or debris growing in open joints and water getting into walls through failed joints, we can put it right.
Around Frogham, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water usually gets in, and they need the right sealant at the right depth.
You are covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or email us.

What else we do in Frogham
Common problems we fix in Frogham
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
Most people get in touch when they notice one of these:
- Old sealant gone brittle and cracked
- Brick movement joints where the sealant has split
- Cracked joints where brick meets render or frames
- Movement joints filled with mortar instead of sealant
If you let a flat or house near Snowdown station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Outside joints around Frogham
Historic houses like Goodnestone Park (about 2.4 miles north) are a reminder that the area around Frogham has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as Nonington Church of England Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Homes close to Church of St Nicholas include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

FAQs for Frogham
Will you come out to Frogham?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Snowdown station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
Can you do several jobs on one visit?
Yes. More than one area can be quoted together.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.
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.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or send us an email.
What is a movement joint?
Brickwork, render and cladding all move a little, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
Where is Mr Mastic based?
We work from Crawley. We cover Frogham and the rest of Kent, along with the rest of our area.
DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
If you do try it yourself, take your time over the 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.
What sealant work cannot fix
We’d rather tell you now than do work that will not last, so these are the limits:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracked brickwork or render that needs a builder or plasterer
- Loose or hollow render, which needs re-rendering
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before you book.
Surfaces we seal
- Copings & trims
- Brickwork movement joints
- Concrete & block
- Façade panels
- Render & cladding joints
- Joints between brick and frames
Why deal with it now?
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together and it means sorting access once. Around Frogham, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.
Why us?
- White, clear, grey or another colour, product permitting
- We leave the area clean and tidy
- Colour picked to suit the job
- Any old sealant cut out fully, not covered over
Read our cost guide or what customers say.
Looking after it afterwards
To keep the joints looking good and working properly:
- Point out the joints to other trades
- Act on the first splits you see
- Do not let climbing plants root in the sealant
- Keep water from gutters off the wall
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
How the visit works
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. The job normally takes a few hours to a few days, depending on the length of joint and the access, and we explain the cure time before we leave. Somewhere like Frogham needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, the joints are inspected and the access agreed.
- 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.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Let us know about earlier repairs to the joints
- For business premises, tell us about site rules or sign-in
- Tell us if parking is tricky
