About our external mastic in Connaught Village
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. We pick a colour that sits well with the wall so the line blends in. If you are dealing with joints pointed up with cement by mistake and damp patches traced to an open external joint, we can help, whatever the surface.
London’s terraces and conversions often share walls, gutters and downpipes with their neighbours, so a leaking gutter joint or failed wall joint can affect more than one home. In a converted house in Connaught Village, it’s worth checking who is responsible for the outside before booking.
Your job is guaranteed for a year, as with all our work.

Surface by surface
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. We choose the product to suit.
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. A primer goes on where the product requires one.
What happens if it’s left?
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way, and access only has to be arranged once. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Connaught Village.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first.

External mastic in Connaught Village: local notes
In terraces and conversions, gutters and walls are often shared with the neighbours, so it’s worth agreeing who is responsible before work starts. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Connaught Village is in London, so parking needs planning: let us know about parking bays, permits or a driveway. For landlords with property near London Paddington station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you look after a building such as Hampden Gurney CofE Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Connaught Village questions
Can you help a landlord with a rental near London Paddington station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Is parking an issue for external mastic in Connaught Village?
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.
How often do external joints need resealing?
It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges, and reseal at that point.
Can you seal joints between two different materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. We pick a colour that works with both materials.
Is the work guaranteed?
Yes. All our work carries a one-year guarantee.
How do I get a quote for external mastic in Connaught Village?
Size, access and the old material all affect the cost. Ask us for a quote.
Can a movement joint be filled with mortar?
No. A mortar-filled joint can’t move, so the wall cracks somewhere else instead. Use a flexible sealant with backing rod.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit.
What happens on the day
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes a few hours for a handful of joints, longer for a whole elevation from start to finish. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Connaught Village. It helps if you can point us to a visitor permit or a bay close to the door.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any parking rules near the property
- Clear the area around the work

When it is not the sealant
It helps to know what we can’t do:

- Damp from another source, such as a leaking gutter or a bridged damp-proof course
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before booking.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Landlord and commercial work in Connaught Village
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
