External mastic for homes and businesses in Earlswood
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing. If you’re dealing with damp patches traced to an open external joint and old sealant gone brittle and cracked, we can put it right, whatever the surface.
In and around Earlswood, older properties sit alongside newer ones, each with its own outside joints. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Your questions about external mastic in Earlswood
Do you work for landlords with property near Earlswood (Surrey) station?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Is Earlswood within the area you cover?
Yes. Earlswood is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Do you seal joints where cladding meets other materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so the joint between them must be flexible. The sealant is matched to both sides.
Is the work guaranteed?
Yes, for a year. If anything is not right with the work within the year, let us know and we’ll sort it.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Should I point up the gap in my brickwork?
No. Rigid materials cannot move with the wall and the joint fails. Where a joint has been mortared, it can often be raked out and sealed properly.
How often do external joints need resealing?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges and have them redone then.

How the job changes by surface
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
Looking after it afterwards
After the cure time, these simple habits help:
- Check external joints each spring
- Deal with leaking gutters that soak the joints below
- Get split or bare joints resealed while the damage is small
- Keep high-pressure jets off the joints
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
Walls and rooflines in Earlswood
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.
If you let a flat or house near Earlswood (Surrey) station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you look after a building such as St John's Primary School, its movement joints, gutters and trims need looking after like any other building’s.

Landlord and commercial work in Earlswood

Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll give you a quote.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Why deal with it now?
Water gets in through a failed movement joint. Resealing early keeps the job to the joint itself, rather than the wall around it. In an older home around Earlswood, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.

What sealant work cannot fix
In fairness, some problems need a different trade:
- Movement that is more than a sealant joint can take
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cutting new joints into brickwork, which is building work rather than sealant work
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before you book.
