About our mastic sealing in London Fields
Owners and agents typically inherit a building’s mastic rather than choose it, and it ages quietly: window perimeters, door frames, external joints and communal junctions all rely on it. When it hardens, splits or pulls away, water and draughts follow, and occupiers start reporting it. If you have occupiers reporting cold air round windows and brittle perimeter mastic across a building, we can help, on external wall and movement joints, communal kitchens and washrooms and communal entrances and stairwells alike. Most enquiries from London Fields start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Across Greater London, London Fields included, the ULEZ applies, and parking and loading rules differ from street to street. For a block or estate, it helps to know where we can park and stage materials.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

General trades versus a specialist
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Why deal with it now?
Reacting to every complaint means sending someone out block by block. A planned programme treats each building once and is simpler to manage and budget. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

How a job runs
Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. In London Fields, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- First we look at the mastic on each building and note what needs replacing.
- We send a fixed quote that sets out the joints, the products and the programme.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Preparing the site
- Tell staff and tenants when we will be in
- Tell us what induction or permit system the site runs
- Have the specification and drawings to hand

Maintenance after handover
After handover, these steps help:
- Include mastic in your cyclical inspections
- Share the asbestos register when you send details
- Look at the sunniest and most exposed elevations first
- Group repairs into a planned programme
Log the date and extent of the resealing for each block. That makes future programmes easier to plan and shows what was done.
Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.
FAQs: London Fields
Is Bayford Street Industrial Centre, near London Fields, within your area?
Yes, sites like Bayford Street Industrial Centre are within our area, along with the rest of London Fields. A few photographs and the unit address let us price the work.
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Will you come and look before quoting?
It depends on the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
How long does a job like this take?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
Can you seal joints high up on a block?
Every block is different. We agree access with you at quote stage so there are no surprises.
Do you check for asbestos in old sealant?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.
