Construction mastic in Seven Dials
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. Sealing too early only means coming back once others have damaged it. If you have old sealant on a refurbishment that needs stripping before new work and sealant knocked or painted over by other trades, we can help, on window and door perimeters, floor and skirting junctions and internal decorators’ caulk alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Seven Dials it comes down to the same thing: the right product in a properly prepared joint.
On a small site around Seven Dials, the mastic is best done in the fewest visits we can manage. Tell us when scaffold comes down and when decoration finishes, and we will plan around those stages.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Why deal with it now?
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. Small buildings around Seven Dials suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Advice
What affects the price in Seven Dials
Each job is priced on its own details. The main factors are:
- Phasing around occupants
- Location, for remote and island sites
- Specialist products, such as fire-rated or hygienic sealants
- Quantities, in metres or numbers
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
Before you send an enquiry
Diagnosis starts before we arrive. Let us know:
- What the building is and how it’s used
- The postcode of the building
- Approximate linear metres or a joint schedule
- How the joints are reached, and at what height
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.

Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

It can be part of the package where specified. Tell us what records you need and we’ll confirm with the quote.

What the job involves on each surface
Internal decorators’ caulk
Caulking is often done in a hurry by whoever’s on site. Done properly, it saves decorators time and gives a clean line and reduces snags.
Kitchens and utility areas
Commercial kitchens often need hygienic or food-safe sealants. We follow the specification and seal to a smooth, cleanable finish.
What we can’t put right
Being straight saves everyone time. Fresh joints won’t solve:
- Damage to finishes by other trades after we’ve sealed
- Specifying the product where the designer hasn’t
- Frames fitted out of tolerance
If you are not sure, just call 01277 525 020 or email us and we will give you a straight answer.

New build and refits around Seven Dials
With the shore within about 1 mile, Seven Dials counts as a coastal location. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. At about 46 miles from central London, Seven Dials is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes.
Recladding or extending a unit at a site like Centenary Industrial Estate, 0.9 miles north-east of Seven Dials, brings panel joints and frame perimeters into the programme. For a contractor at a hotel such as Abbey Hotel, less than half a mile south-west of Seven Dials, the mastic often has to be finished before a reopening date. New wings at hospitals like The Montefiore Hospital (under half a mile west of Seven Dials) bring long runs of window and panel joints to seal.

General trades versus a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
