On site: what to expect
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes a few days for most blocks, with larger programmes scheduled building by building, and we clear our waste as we work. Planning a London job such as one in Brimsdown starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we’ll schedule to suit.
- We check the asbestos register for older buildings and look at the joints.
- A fixed quote covers the joints, products and order of work.
- Failed mastic is removed completely.
- Joint faces are cleaned, backed and resealed.
- Buildings are completed in turn.
What we need from you

Advice
Mastic sealing in Brimsdown
Owners and agents usually inherit a building’s mastic rather than choose it and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. Once it cracks, hardens or comes away, draughts and water find a way in along with complaints. We work on communal entrances and stairwells, window and door perimeters on blocks and external wall and movement joints, and the failures we’re asked to look at most are draughts at frames across a block and complaints coming in block by block. Whoever orders the work in Brimsdown, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
Planning mastic work on a London block means notices to residents, access to flats and agreed working areas. Work is planned with the agent so residents get notice and access is arranged in advance.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

What else we do in Brimsdown
Your questions answered
Can you work in a London building with booked loading and goods-lift slots?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it
Does your area include sites such as Brimsdown Industrial Estate, near Brimsdown?
Yes, sites like Brimsdown Industrial Estate are within our area, along with the rest of Brimsdown. To start, just ring 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Do you take on small jobs?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.
Can you quote from photographs?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Can you seal joints high up on a block?
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 will tell you how we’d approach it.
Does weather matter for sealant work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Mastic sealing in Brimsdown: the local picture
Brimsdown has five care or nursing homes no more than 2 miles away. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings. In London, mastic work on a block goes through the managing agent or landlord, with notice to residents. We plan around the notices and access you arrange.
Trustees of buildings like Ss Peter and Paul Church can bring frame and external mastic into a planned maintenance list. If you look after a block within reach of Brimsdown station, under half a mile to the south-west of Brimsdown, frame and balcony mastic can be renewed on one programme.

Communal areas
We keep entrances and stairs open throughout. We work in sections so access is never blocked.
Commercial and mixed-use buildings
Tenants in commercial buildings need to keep trading, so we plan around them.
Signs you need mastic sealing in Brimsdown
Much failed sealant was laid on dirty, dusty or damp surfaces. Without clean, sound faces and a primer where the product needs one, the bead peels off one side.
It’s worth sending us details if you spot any of the following:
- Failed external movement joints
- Damp patches beside frames
- Complaints coming in block by block
- Patchy repairs in mismatched sealant
If your remit includes a building such as Brimsdown Primary School, frame and door mastic can be programmed for the holidays.
What your quote should include
- Will RAMS and insurance details be available?
- Are they CHAS accredited or on Constructionline?
- Do they follow the manufacturer’s priming guidance?
- How the existing material will be dealt with
General trades versus a specialist
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
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 sets the cost
Before we quote, we look at:
- How much existing material needs removing
- The site’s rules and procedures
- The product specified
- Backing rod, priming and other preparation
The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.
What to include in your enquiry
For an accurate fixed quote, we need a clear picture of the site. Useful things to include:
- Access details, including height
- Your programme or deadline
- Photos of the joints, close up and from further back
- Approximate linear metres or a joint schedule
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
Why act early in Brimsdown
Replacing mastic before water gets in is a planned job. After water has got in, there may be damp, damaged plaster or decoration to put right too and occupiers notice. 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.
Pricing mastic joints depends on quantities, condition and access, and any specification that applies. Call for a quote.
