Landlord and commercial work in Broom Hill
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
How we handle external mastic in Broom Hill
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it. If you have failed seals between different materials and weeds or debris growing in open joints, we can help.
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. For a flat in Broom Hill, check the lease for who looks after the outside.
Big or small, you get the same one-year guarantee.

Your questions about external mastic in Broom Hill
Can you do external mastic in Broom Hill?
Yes. Our work covers London and the South East, and Broom Hill is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
Can parking be tricky for a visit in Broom Hill?
Parking in Broom Hill, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Can you reach joints on upper floors?
That depends on how high the joints are and the ground below. Ground-floor joints are simple; for higher ones, send details and we will confirm the access.
Should I point up the gap in my brickwork?
No. Rigid materials can’t move with the wall, so the joint stops doing its job. If it has already been filled, we can usually cut it out and reseal it.
Are you fully insured?
Yes. We are fully insured.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us and we are fully insured.
Why do you put foam in the joint first?
Backing rod goes into deeper joints as a matter of course. It sets the sealant depth and prevents three-sided bonding so the bead can stretch.
What affects the quote in Broom Hill
Call for a quick quote. What matters most is:
- Whether old sealant or filler has to be cut out
- The amount of work
- How many rooms, windows or areas are involved
- When we can work, for business premises
Doing several joints on one visit is usually more efficient than separate visits. You will get one clear quote for the whole job.
Asking for a quote
You do not need to know the technical terms. Just tell us:
- The rough size of the job
- If it’s domestic, commercial or a hotel
- The problem you’ve noticed
- Any previous sealing or DIY work
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.

How the job changes by surface
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. We reseal them with a low-modulus sealant over backing rod.
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.
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Fix overflowing gutters above sealed joints
- Leave the joints unpainted unless we have said otherwise
- Tell anyone working on the walls about the movement joints
- Clear growth from the base of walls and joints
Keep pressure washers away from the sealant. High-pressure water can lift the edges over time.
Once a joint cannot move, the wall finds another way, normally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
Leave it or put it right?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render, so the problem grows beyond the joint itself. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Broom Hill, the repair is bigger than the sealant job would have been.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
Why book with us
- Neat joints and a tidy finish
- You choose the colour before work begins
- Full insurance on every job
- A sealant colour to suit the surroundings

Broom Hill buildings and the weather
London terraces and converted houses often share gutters, downpipes and walls, so check who is responsible for the outside before booking. 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.
Schools such as Perry Hall Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you let a flat or house near Orpington station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Homes close to Church of All Saints include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

- Adding movement joints to masonry that has none
- 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
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.
