External mastic for homes and businesses in Bush Hill Park
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. We work on concrete & block, copings & trims and joints between brick and frames, and common reasons people get in touch are moss and dirt in joints with no sealant left and sealant that has lost its bond to the brick or render.
In London terraces and converted houses, gutters and walls are often shared with the house next door, so a leaking gutter joint or failed wall joint can affect more than one home. In a converted house in Bush Hill Park, it’s worth checking who is responsible for the outside before booking.

Common questions in Bush Hill Park
Is parking a problem for a job in Bush Hill Park?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Do you cover Bush Hill Park for external mastic?
Yes. Our work covers London and the South East, and Bush Hill Park is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.
Is the work guaranteed?
Yes: twelve months. If anything is not right with the work within the year, let us know and we’ll sort it.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
I’m a tenant. Can you help?
We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. Indoors, that usually means someone at home.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or send us an email.
What the job involves on each surface
Render joints
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out.
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two so neither cracks the other.

Common problems we fix in Bush Hill Park
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.
The problems people generally mention when they call include:
- Water getting into walls through failed joints
- Rigid filler in a joint that should flex
- Moss and dirt in joints with no sealant left
- Hard, crazed mastic that has stopped moving
Rented homes near Bush Hill Park station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
For landlords and businesses
Landlords and letting agents in Bush Hill Park can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
We also work for property managers and facilities teams. We can quote a run of properties together.

Related advice
Why it’s worth doing now in Bush Hill Park
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. In a flat in Bush Hill Park, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
