About our mastic sealing in Coombe
We diagnose before we prescribe: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in, with backing rod setting the depth where it’s needed. We work on communal entrances and stairwells, external wall and movement joints and window and door perimeters on blocks, and what we’re called in for most is failed external movement joints and draught complaints from residents or tenants. A single leaking joint is often how a building in Coombe first comes to us: we look at the rest while we’re there and tell you what we find.
London’s ULEZ covers every borough, and parking and loading rules vary street by street. For block-wide work, a place to park and store materials saves time on every visit.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Blocks and managed buildings in Coombe
For a London block, the agent or landlord normally handles notices to residents and access to flats. Our programme follows the access you agree with residents. Seven care or nursing homes sit less than 2 miles from Coombe. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings.
Trustees of buildings like Christ Church New Malden can bring frame and external mastic into a planned maintenance list. Schools and community buildings such as Coombe Hill Junior School need frame and external mastic kept sound like any building. If you manage student housing near a university such as Kingston University, which lies west of Coombe, the summer turnaround is the time for mastic.

Surface by surface
Communal areas
Joints at low level in communal areas take knocks from bins, bikes and buggies and tend to fail first.
Window and door perimeters on blocks
On most blocks, the frame-to-wall joint is where failure shows first. Old perimeter mastic is removed, the joint prepared and new sealant tooled in.
When to bring in a specialist
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
From enquiry to sign-off
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before we move to the next. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- We inspect the joints, building by building, and record what has failed and why.
- A fixed quote follows, split by block or building if that suits you.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Old sealant is stripped and each face prepared back to firm material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Preparing the site
- Send any specification or drawings in advance
- Flag any permit to work we’ll need
- Make sure the joints can be reached

Related advice
After the work
For the best life from the joints:
- Group repairs into a planned programme
- Keep a record of when each building was resealed
- Ask residents or tenants to report leaks and draughts early
- Look at the sunniest and most exposed elevations first
Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.
Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first.
Coombe: questions and answers
Can you work in a London building with booked loading and goods-lift slots?
Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for
Can you work in a care home near Coombe with residents in?
Yes. We agree rooms and times with the manager and work a few areas at a time. Tell us about any infection-control or safeguarding requirements and we’ll work to them.
Do you check for asbestos in old sealant?
We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Can weather delay the job?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
What about access for upper-floor joints?
Access is discussed and agreed before the quote is fixed. Tell us the number of storeys and whether scaffold or other access is planned, and we’ll tell you how we’d approach it.
