Looking after buildings in and around Hackney Wick
Blocks in London are usually run by managing agents, landlords or housing associations, with residents to notify and access to arrange. We plan around the notices and access you arrange. The 2 miles around Hackney Wick include 25 care or nursing homes. Care home owners need frame and external mastic kept sound without unsettling residents.
If you own or manage units on a site such as Hamlet Industrial Estate, which lies north-east of Hackney Wick, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Student blocks close to universities like University of Staffordshire London Campus (less than half a mile north of Hackney Wick) are easiest to work on between tenancies.

About our mastic sealing in Hackney Wick
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. Most enquiries involve draught complaints from residents or tenants and repeated reactive repairs to the same buildings, on window and door perimeters on blocks, communal entrances and stairwells and shopfronts below residential blocks. Whoever orders the work in Hackney Wick, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
London’s ULEZ covers every borough, and parking and loading rules vary street by street. For block-wide work, a place to park and store materials saves time on every visit.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Hackney Wick: questions and answers
Can you quote for a block close to Hackney Wick station?
Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.
Will you work in a care home in Hackney Wick without moving residents out?
Yes, with the manager deciding the order and timing of rooms. Tell us about any infection-control or safeguarding requirements and we’ll work to them.
How long before the joints can be used?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
What about access for upper-floor joints?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned and we’ll confirm the approach in the quote.
Do you guarantee the mastic work?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Common problems we fix in Hackney Wick
The edges of the material itself sometimes break away, such as crumbling render, brick arrises or frame edges. We’ll tell you if the joint edges need repairing before resealing.
Things that typically lead to an enquiry:
- Window mastic that has split and shrunk
- Communal area joints that look neglected
- Movement joints with sealant missing
- Draughts at frames across a block
Older community buildings, St Mary of Eton among them, often have frames of mixed ages whose mastic varies.
Questions to ask before you book
- Whether their applicators hold CSCS cards
- Which product they’ll use, and why it suits the joint
- Their approach to joint depth and backing
- What site paperwork they can supply
From enquiry to sign-off
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before the next one starts. For a job in Hackney Wick, access comes first. Give us the hours we can be on site and we will schedule to suit.
- First comes a look at the joints and, for older buildings, the asbestos records.
- The products and programme are set out in a fixed quote.
- Failed mastic is removed completely.
- Joint faces are cleaned, backed and resealed.
- We finish each building before moving to the next.
Preparing the site
- Send your site hours and access windows
- Send any specification or drawings in advance
- Make sure the joints can be reached

When to bring in a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
What we can’t put right
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:
- Frames that are rotten, warped or broken
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Masonry that has broken away beside the joint
If you are not sure, just ring 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.
Joints and surfaces we work on
- External wall and movement joints
- Communal entrances and stairwells
- Communal kitchens and washrooms
- Window and door perimeters on blocks
- Balcony and threshold joints
- Shopfronts below residential blocks
Leave it or put it right?
Looking at mastic during planned maintenance costs little. Leaving it until there’s a leak turns it into reactive work with less control over timing. 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. For a fixed figure, call for a quote.

Cost factors for mastic joints
To price the job, we consider:
- Phasing around occupants
- Access and working height
- The product specified
- Joint width, depth and condition
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
What to include in your enquiry
It doesn’t need to be a full survey. A few details are enough to get going:
- The type of building and who uses it
- Any specification or named product
- Approximate linear metres or a joint schedule
- The site address and postcode
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
