About our mastic sealing in Chelsea Harbour
Across Chelsea Harbour and the rest of Greater London, we work the same way: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. Addresses, photographs of typical joints and a rough idea of quantities let us give a quick quote or we can visit. We work on shopfronts below residential blocks, communal entrances and stairwells and balcony and threshold joints, and what we are called in for most is damp patches beside frames and no planned programme for sealant. Whether you call it commercial sealant work, mastic application or joint sealing, in Chelsea Harbour it comes down to the same thing: the right product in a properly prepared joint.
Across Greater London, Chelsea Harbour included, the ULEZ applies, and parking and loading rules differ from street to street. For a block or estate, it helps to know where we can park and stage materials.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

Why it’s worth doing now in Chelsea Harbour
Reacting to every complaint means sending someone out block by block. Planned resealing covers a whole building or estate in one go, under a single quote and a single programme. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
A quote for mastic joints depends on how many there are, their condition and the access. Call for a quote.
Why appoint us
- Commercial sealant work since 2005
- RAL and finish matching where the product range allows

Diagnose, treat, sign off
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes a few days for most blocks, with larger programmes scheduled building by building, and we clear our waste as we work. All of Greater London is in the ULEZ, and kerbside space in Chelsea Harbour can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- We inspect the joints, building by building, and record what has failed and why.
- You get a fixed quote, priced per building where that helps your budgeting.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
What we need from you
- For older buildings, check the asbestos register before work
- Tell us your opening times and when work is allowed
- Agree which areas must stay open

Advice

Looking after buildings in and around Chelsea Harbour
Blocks in London are usually run by managing agents, landlords or housing associations, with residents to notify and access to arrange. We plan around the notices and access you arrange.
For owners of several units at places like Town Mead Business Centre, which lies south of Chelsea Harbour, one programme can deal with frame and external mastic across the lot. Blocks of flats and mixed-use buildings often cluster around stations such as Imperial Wharf station (to the west of Chelsea Harbour) and their window and balcony mastic tends to age at the same rate across a building. Trustees of buildings like St Mary's Church can bring frame and external mastic into a planned maintenance list.

Should maintenance staff do it?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: 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: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
What we can’t put right
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:
- Masonry that has broken away beside the joint
- Misted or failed double-glazed units
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
If you are not sure, just call the office on 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

Common questions from Chelsea Harbour clients
Will you take on work at estates like Town Mead Business Centre, close to Chelsea Harbour?

Do you work for managing agents with blocks near Imperial Wharf station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.
Do you work in Chelsea Harbour?
Yes. We take on work across Chelsea Harbour.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
Does weather matter for sealant work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
