Landlord and commercial work in Baker's Cross
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
External mastic in Baker's Cross, done properly
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, and we do not skip that step. We work on render & cladding joints, concrete & block and copings & trims, and the jobs we see most are leaking joints around cladding and façade panels and joints where the bead has come unstuck.
Around Baker's Cross, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
Each job carries a 12-month guarantee.

Baker's Cross questions
Can you do external mastic in Baker's Cross?
Yes. We work across London and the South East, and Baker's Cross is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing, and we’ll send you a clear quote.
Is there a guarantee on external mastic in Baker's Cross?
All our work, in Baker's Cross and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Can you reach joints on upper floors?
It depends on the building. We work on joints that can be reached safely. Give us some details and we will confirm the access.
What’s an expansion joint in brickwork?
Brickwork, render and cladding all move a little, and planned joints take up that movement. It’s closed with backing rod and a flexible sealant.
Can you quote for more than one area?
Yes, we can. More than one area can go on one quote.
How long should I leave it?
It depends on the product and the temperature. We tell you how long to leave it before we go.
Can you seal joints between two different materials?
Yes. Joints between dissimilar materials are a big part of external work. The sealant is chosen to bond to both sides with primer where required.
Do you work for letting agents?
Yes. We work in homes, commercial premises and hotels.
Why act early in Baker's Cross
Resealing a run of joints in one go is usually better than patching one at a time. Joints of the same age tend to fail together. In a small place like Baker's Cross, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
Why Baker's Cross clients choose us
- We agree the colour with you first
- We never seal over old sealant
- Fully insured
- Domestic, commercial and hotel work
Honest limits
We won’t take on work that will not last, so these are the limits:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Rising or penetrating damp from elsewhere in the wall
- Cracked brickwork or render that needs a builder or plasterer
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think before you book.
What we seal
- Copings & trims
- Concrete & block
- Façade panels
- Render & cladding joints
- Joints between brick and frames
- Brickwork movement joints
How the job changes by surface
Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. A primer goes on where the product requires one before sealing.
Render joints
Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.
How the visit works
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Baker's Cross needs a little journey planning: 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.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- 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
- Move anything stored near the joints
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive

Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near Church of St Dunstan, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
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 we are called out for in Baker's Cross
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
Signs it’s time to call us include:
- Damp patches traced to an open external joint
- Panel joints letting water in
- Rigid filler in a joint that should flex
- Sealant pulling away from one side of the joint
Managing a site like Cranbrook School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
