How we handle external mastic in Friday Street
Joints in render and cladding are easy to overlook until a damp patch appears. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a matching colour. If you are dealing with rain getting behind render or cladding at a joint and joints where the bead has come unstuck, we can put it right, on façade panels, concrete & block and copings & trims alike.
Somewhere as small as Friday Street, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

What we’re called out for in Friday Street
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
Any of these means the joints need attention:
- Leaking joints around cladding and façade panels
- Cracked joints where brick meets render or frames
- Rain getting behind render or cladding at a joint
- Sealant pulling away from one side of the joint
Managing a site like Belmont Prep School? Then its movement joints, gutters and trims need looking after like any other building’s.

Friday Street questions
Can you do external mastic in Friday Street?
Yes. Our work covers London and the South East, and Friday Street is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
I let a flat near Gomshall station. Can you help?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
Are you fully insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
Where do you work from?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
How do I get a quote for external mastic in Friday Street?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
What happens if it’s left?
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and doesn’t last so it’s worth doing right. Older cottages and farmhouses around Friday Street can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and send you a clear quote before we start.

What we can’t put right
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Subsidence or other structural problems
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Walls that need new movement joints cut into them
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly before booking.
What we seal
- Render & cladding joints
- Concrete & block
- Façade panels
- Joints between brick and frames
- Copings & trims
- Brickwork movement joints
What we do, step by step
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. For a village or hamlet like Friday Street, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Keep children and pets away from the work area
- Clear the area around the work
- Tell us about any water getting in

Landlords, agents and businesses in Friday Street
We work for letting agents and landlords as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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.

What external mastic looks like in Friday Street
Rainfall in the South East is lower than in much 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 Polesden Lacey (about 4.2 miles north) nearby, there’s older building stock in the area around Friday Street 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.
For an older house near a landmark such as Church of St James, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Letting a property close to Gomshall station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.
