What affects the price in Heron Quays
These are the things that shape the price:
- The total length or number of joints
- How accessible the joints are
- Site requirements such as inductions and permits
- Whether the work must be split into stages
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
Whether it’s one area or a whole building, these details speed things up:
- Any dates the work must fit around
- Approximate linear metres or a joint schedule
- Specification clauses that apply
- The type of building and who uses it
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.
About our facade sealing in Heron Quays
External joints face UV, rain, temperature swings and building movement all year. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When the time comes, we cut the old sealant out completely and start again. We work on shopfront frames, perimeter joints where frames meet the structure and window and door perimeters, and what we’re called in for most is gaps between rainscreen or cladding panels and air leaks through failed facade joints. Whoever orders the work in Heron Quays, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Why it’s worth doing now in Heron Quays
Scaffold or access already on site makes resealing much simpler. Coordinating facade sealing with other external works avoids paying for access twice, saving a second set-up. Failed sealant in a building in Heron Quays can quickly affect neighbours, tenants or the floor below. Dealing with it early is simpler for everyone.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.

FAQs: Heron Quays
Will you plan work around the academic year at somewhere like University of Sunderland in London?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is 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. We allow for the ULEZ, which covers every borough
Do you run new sealant over the existing bead?
No. New sealant won’t hold on old sealant, so the old bead is cut away and the faces are cleaned before resealing. That is what makes the new joint last.
Can weather delay the job?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Is the work guaranteed?
Yes. The 12-month guarantee covers our preparation and application, though not damage or work by other trades.
Can you look at water coming in around a frame?
Yes. Photos help, and you can call 01277 525 020 or use the quote form to arrange a visit. Failed perimeter sealant is a common cause, but not the only one, and we will be honest about which it is.

Facade sealing in Heron Quays: the local picture
The area within 2 miles of Heron Quays holds plenty of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Heron Quays. Deliveries are booked and storage is tight, so mastic materials come in as needed.
Recladding or extending a unit at a site like Poplar Business Park, 0.6 miles north-east of Heron Quays, brings panel joints and frame perimeters into the programme. Work at a hotel such as Hotel Britannia International (less than half a mile south of Heron Quays) tends to be programmed around bookings, mastic included. Hospital estates such as The London Independent Hospital, 1.6 miles north-west of Heron Quays, 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.

Site staff or a sealant specialist?
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
Work for main contractors and building owners
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Our process
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before we move to the next. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- 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
- Flag any permit to work we will need
- Confirm the product named in the specification
- Share the asbestos register for older buildings
Getting a fixed quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

Perimeter joints at frames and structure
Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. We seal those perimeter joints.
Brick and stone facades
Stone can absorb plasticisers from the wrong sealant. We use a product suitable for the stone where the specification names one, and mask the edges carefully.
