Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Site staff or a sealant specialist?
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Construction mastic for commercial buildings in Isle of Dogs
Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old, and on older buildings we ask for the asbestos survey before disturbing anything. New and existing joints then get the same preparation. If you’re dealing with mastic snags holding up handover and early adhesion failures on new external joints, we can help, on floor and skirting junctions, window and door perimeters and internal decorators’ caulk alike. Whoever orders the work in Isle of Dogs, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Every London site, Isle of Dogs included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.
Work we carry out in Greater London comes with a 12-month guarantee. Should something we installed fail, call 01277 525 020 or email drawings and photos and we’ll come back to it.

Cost factors for mastic packages
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Site requirements such as inductions and permits
- Joint width, depth and condition
- Whether old sealant has to be cut out first
- The product specified
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Details that help us quote
There’s no need for a formal survey. A few details are enough to get going:
- Asbestos survey details if the building is older
- Any specification or named product
- What the building is and how it’s used
- Photos of the joints, close up and from further back
To get a fixed quote, phone 01277 525 020 or email a schedule or drawings, telling us the site location and the nature of the job. You can also send details through our quote form.
When something else is needed
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Joint design decisions that belong to the architect or engineer
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
If you are not sure, just ring 01277 525 020 or use the quote form and we will give you a straight answer.

FAQs: Isle of Dogs
Can you work around term dates at a campus such as University of Greenwich - Greenwich Campus?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Can you work in a London building with booked loading and goods-lift slots?
Yes, most London buildings have access rules of some kind, and we plan around them. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for
Will you stick to the specified products?
We use the product the specification names. Any suggested alternative is put to you before anything changes.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Do you cover Isle of Dogs?
Yes. Sites across Isle of Dogs are covered.
Which sealant will you use?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Are you fully insured?
Yes. Our insurance certificate can be sent alongside the quote.
Why deal with it now?
It helps to bring the mastic subcontractor in before the package is urgent. Early involvement means gaps, products and access are sorted before the programme bites, which avoids last-minute problems. Called in at the end, the same issues surface during handover. Getting scaffold, permits or access booked in Isle of Dogs takes effort, so it makes sense to deal with every failing joint while access is in place.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

How the job changes by surface
Snagging before handover
Snags usually come from damage by following trades, missed joints or poor earlier work. We price snagging as part of the package or as a separate visit.
Window and door perimeters
A frame gap that’s too wide can’t just be filled with sealant. Gaps outside the product’s range are raised with the site team.

A 2-mile radius around Isle of Dogs takes in a good number of hotels. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included. Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Isle of Dogs. Delivery slots and scarce storage shape how and when the mastic goes in.
For contractors at a college like Bellerbys College London, which lies south of Isle of Dogs, perimeters and internal sealant are timed for the holidays. Extensions at sites like Blackheath Hospital (to the south-east of Isle of Dogs) typically sit beside working departments, and the mastic follows strict access rules. Work at a hotel such as Hotel Britannia International (to the north of Isle of Dogs) tends to be programmed around bookings, mastic included.

From enquiry to sign-off
Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.

- You receive a fixed quote covering scope, products and sequence.
- Paperwork is agreed and applicators are inducted on site.
- Sealing follows the programme as areas are released.
- Problems we find, such as oversized gaps, are raised right away.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Preparing the site
