How we handle facade sealing in Isle of Dogs
Facade sealants sit in the sun, rain and frost every day, so they don’t last indefinitely. Life depends on movement, weathering, product choice and the quality of the original work. When the time comes, we cut the old sealant out completely and start again. The enquiries we see most involve leaks at window and door perimeters and weathered facade joints that have lost their grip, on stone and brick facade joints, window and door perimeters and cladding panel joints. A single leaking joint is often how a building in Isle of Dogs first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Every London site, Isle of Dogs included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Alongside that, sites usually need booked deliveries and a plan for where materials go.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

What the job involves on each surface
Window and door perimeters
Frames grow and shrink with temperature, and the perimeter joint has to follow. Rod placed at the right depth lets the bead stretch as the frame moves.
Perimeter joints at frames and structure
Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. Our work is that perimeter joint, not the framing or glazing itself.
Site staff or a sealant specialist?
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. That’s why many clients bring in a specialist from the beginning.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Honest limits
We check first that sealant really is the fix. It isn’t the answer for:
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Joints whose design needs changing by the specifier
- Render or concrete edges that have broken away
If you are not sure, just speak to us on 01277 525 020 or email drawings and photos and we will give you a straight answer.

Quoting for work in Isle of Dogs
The price varies from site to site. Expect it to depend on:
- Induction, permit and paperwork requirements
- Joint width, depth and condition
- Which sealant the job calls for
- Whether old sealant has to be cut out first
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.
What to include in your enquiry
A few photographs plus some basic facts will normally do. It helps to include:
- The product your specification calls for
- The postcode of the building
- Rough lengths or quantities, or drawings if you have them
- Whether the building will be occupied during the work

Questions we’re asked in Isle of Dogs
Can you work around term dates at a campus such as University of Greenwich - Greenwich Campus?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Do you work in London buildings with loading restrictions?
Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we will plan accordingly. All of Greater London is inside the ULEZ, and our planning allows for it
Do you provide access for facade work?
We agree access with the client at the start. Let us know what access is in place or planned, and the quote will reflect it.
Is it okay to overlay old mastic?
No. A bead run over old sealant soon lifts. Our method is a full cut-out, cleaning, backing and a new bead.
Can the building stay open while you work?
In most cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.
What will the job cost?
There isn’t a price list, because every site is different. Send photographs or drawings and we will price it at a fixed figure.
Is Isle of Dogs in your area?
Yes. We take on work across Isle of Dogs.
From enquiry to sign-off
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- We look at the joints, the drawings and the access before pricing.
- The old bead is cut away completely, not overlaid.
- Both faces are cleaned and, where the product needs it, primed.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- We walk the finished joints with you before handing over.
Before we start on site
- Tell us your opening times and when work is allowed
- Flag any permit to work we will need
- Confirm the product named in the specification
Quotes
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or email drawings and photos.

Building and refurbishing in Isle of Dogs
Site traffic in Isle of Dogs falls within London’s ULEZ, like everywhere else in Greater London. Delivery slots and scarce storage shape how and when the mastic goes in. There are plenty of hotels within about 2 miles of Isle of Dogs. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight.
Hotel extensions and refits, at places such as Hotel Britannia International, 0.9 miles to the north of Isle of Dogs, typically run between busy periods, so the sealing is squeezed into short windows. Recladding or extending a unit at a site like Brookmarsh Industrial Estate (to the south of Isle of Dogs) brings panel joints and frame perimeters into the programme. Hospital estates such as Blackheath Hospital (to the south-east of Isle of Dogs) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.
