Work for main contractors and building owners
Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.
Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
Construction mastic in West Barnes, done properly
The specification and the programme set the job. If a product is named, that’s what goes in. Backing, primer and depth follow what the sealant maker sets out so the detail on the drawing is what ends up on site. We work on cladding and panel joints, brick and block movement joints and floor and skirting junctions, and the usual reasons a site gets in touch are inconsistent sealant finishes from plot to plot and perimeter gaps outside the sealant’s range. Most enquiries from West Barnes start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Construction in a London area such as West Barnes means working on constrained sites: small compounds, delivery slots and shared hoists and scaffold. Mastic is typically one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

How a job runs
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- Drawings, the sealant specification and your programme come to us for pricing.
- A fixed quote sets out the scope, the products and the sequence.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- We close out snagging and hand over with a 12-month guarantee.
Preparing the site
- Clear stock, furniture or equipment away from the joints
- Confirm the product named in the specification
- Let building users know which areas are affected

Common problems we fix in West Barnes
A joint without backing rod or bond-breaker often fails early. Bonded to the base of the joint and both sides, sealant can’t stretch evenly.
It’s worth sending us details if you spot any of the following:
- Oversized or tapered gaps around new frames
- Internal caulk splitting as the building dries out
- Failed sealant in an existing building being refurbished
- Missed perimeter joints on a new elevation
Building work at universities like Kingston University, 2.1 miles north-west of West Barnes, is often timed for the summer, mastic included.
Questions to ask before you book
- How joint depth will be controlled
- Health and safety accreditation such as CHAS
- Their plan for phasing and protecting the area
- What level of public liability insurance do they hold?
When it isn’t the sealant
Honesty saves time and money. New sealant won’t cure:
- Designing joint widths or choosing the specification (that sits with the designer)
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Frame gaps too wide for sealant, which the installer needs to correct
If you’re not sure, just give us a call on 01277 525 020 or email us and we will give you a straight answer.

What sets the cost
A fixed quote reflects the actual work. It takes account of:
- Phasing around occupants
- The size and state of each joint
- How accessible the joints are
- Quantities, in metres or numbers
A quote for mastic packages depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.
What we need to price the job
Whether it’s one area or a whole building, these details speed things up:
- The site address and postcode
- Your programme or deadline
- Clear photos of the problem areas
- Anything awkward about access or site hours
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.
Maintenance after handover
For the best life from the joints:
- Flag uneven or tapered frame gaps early
- Keep scrapers and abrasive pads off new beads
- Bring the mastic contractor in after the last trades are through
- Note which sealant went where at handover
Our 12-month guarantee covers the workmanship from sign-off. The guarantee covers how we sealed, not later damage by other trades.
Leaving the mastic snag list to the end squeezes everyone. A planned close-out through each area as it completes keeps the list short, and avoids a rush.
