Construction mastic for commercial buildings in London Fields
The programme rarely stands still, so the mastic package has to flex with it. The sequence is set with the site team and updated as plots or floors are handed over, so applicators arrive when areas are genuinely ready. That keeps the work right first time and saves rework. If you have bath and shower joints scraped during the final clean and old sealant on a refurbishment that needs stripping before new work, we can put it right, on sanitary and kitchen joints, brick and block movement joints and cladding and panel joints alike. Whoever orders the work in London Fields, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
Building sites in London tend to be tight: 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.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, call the office on 01277 525 020 or send photos by email and we’ll come back to it.

Facades, frames and programmes in London Fields
Site traffic in London Fields falls within London’s ULEZ, like everywhere else in Greater London. Deliveries are booked and storage is tight, so mastic materials come in as needed. A good number of hotels sit less than 2 miles from London Fields. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
University estates such as Queen Mary University of London, 1.4 miles south-east of London Fields, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. Hotel extensions and refits, at places such as Kip Hotel, 0.6 miles to the north of London Fields, typically run between busy periods, so the sealing is squeezed into short windows.

How do we ask for a quote?

What guarantee comes with a mastic package?
Each package is backed by a 12-month guarantee. We’re also fully insured for public liability.
Can you quote from photos?
It depends on the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
When can you be on site?
Give us your site hours and any access windows in your enquiry, and we’ll plan around them. Our office runs Monday to Friday, 8am until 5pm.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Cost factors for mastic packages
What shapes the price:
- Joint width, depth and condition
- Removal of failed or old sealant
- Working within restricted access windows
- Location, for remote and island sites
A quote for mastic packages depends on quantities, condition and access, plus any specification you are working to. Ask us for a fixed quote.
What we need to price the job
A few photographs plus some basic facts will normally do. Please tell us:
- Whether the building will be occupied during the work
- Any specification or named product
- Photos of the joints, close up and from further back
- Anything awkward about access or site hours
For a fixed quote, give us a call on 01277 525 020 or send photos by email, telling us the site location and the nature of the job. Our quote form is another easy route.
Why it’s worth doing now in London Fields
Sealing over damaged or contaminated new joints might save a day. Sealant can’t grip a contaminated or existing bead. Damaged joints are removed and resealed from clean faces. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

How the job changes by surface
Window and door perimeters
Internal perimeters are usually sealed with a paintable product where decorating follows. The specification decides which, and colour-matched products can be used where the frame is on show.
Bathrooms, en suites and washrooms
On multi-unit schemes, consistency matters across hundreds of bathrooms. One applicator team gives the same finish everywhere, plot by plot or floor by floor.

What else we do in London Fields
Common problems we fix in London Fields
A joint without backing rod or bond-breaker often fails early. Fixed to three faces, the sealant rips the first time the joint opens.
Most enquiries start with one or more of the following:
- Inconsistent sealant finishes from plot to plot
- Internal caulk splitting as the building dries out
- Frame perimeters left unsealed or poorly sealed
- Snag items on joints that need redoing before handover
For contractors refurbishing units at places like Bayford Street Industrial Centre, under half a mile east of London Fields, the mastic covers cladding panels, roller-door and window perimeters.
Before you book anyone
- How the joint faces will be prepared and primed
- What site paperwork they can supply
- What level of public liability insurance do they hold?
- How joint depth will be controlled
When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It won’t put right:
- Oversized gaps that need packing or adjustment by others
- Designing joint widths or choosing the specification (that sits with the designer)
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.
