Mastic sealing for Donnybrook Quarter sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Our process
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes a few days for most blocks, with larger programmes scheduled building by building, and our waste is bagged and taken away as we go. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- A building-by-building inspection lists the failed joints.
- You get a fixed quote, per block or for the whole programme.
- We agree the programme and dates with you.
- Failed sealant is removed and the faces prepared.
- Joints are resealed and tooled.
- Each building is checked and signed off with the 12-month guarantee.
Getting the site ready
- Send your site hours and access windows
- Send asbestos survey details if the building is pre-2000
- Agree which areas must stay open

About our mastic sealing in Donnybrook Quarter
For blocks and buildings in Donnybrook Quarter and across Greater London, the process is the same: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photographs and approximate joint numbers are enough for a quick quote or we can visit. We work on shopfronts below residential blocks, communal kitchens and washrooms and balcony and threshold joints, and the failures we are asked to look at most are open joints in brickwork or panels and window mastic that has split and shrunk. A single leaking joint is often how a building in Donnybrook Quarter 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.
London’s ULEZ covers every borough, and parking and loading rules vary street by street. For a block or estate, it helps to know where we can park and stage materials.
A 12-month guarantee applies to all our work. If an installation problem shows up, call the office on 01277 525 020 or send photos by email and we’ll arrange a return visit.

Maintenance after handover
Cleaning and maintenance staff play a part too. Share these points with them:
- Protect low-level joints in entrances
- Ask residents or tenants to report leaks and draughts early
- Mention RAMS, insurance or CSCS requirements up front
- Keep a record of when each building was resealed
Our workmanship is covered for 12 months, so report any failure in that time. Beyond that, routine checks spot the next round of repairs.
Planned resealing is easier to budget than emergency repairs. We can quote buildings in priority order so spending is spread.
Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Do you need mastic sealing in Donnybrook Quarter?
UV and rain age external sealant. It stiffens, stops stretching and cracks most of all on the sunniest and most exposed elevations.
If one of these sounds familiar, it’s time for a closer look:
- Complaints coming in block by block
- Estate-wide sealant that is simply worn out
- Open joints in brickwork or panels
- Communal area joints that look neglected
For agents with blocks near Hackney Wick station (0.5 miles north of Donnybrook Quarter), a block-wide mastic programme deals with frames, balconies and entrances in one go.
What to look for in a quote
- Their plan for phasing and protecting the area
- Will failed sealant be removed rather than covered?
- Proof of insurance
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
What the job involves on each surface
Tenement and older buildings
Older buildings, including Scotland’s sandstone tenements, have their own joint details. We look at the substrate before choosing a sealant.
Window and door perimeters on blocks
Frames vary from uPVC to aluminium and timber, and the product is matched to the frame material and the masonry. We will confirm the colours available for the specified product.

FAQs: Donnybrook Quarter
Do you take on jobs in Donnybrook Quarter where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. Share the building’s contractor rules and we will work to them. The ULEZ covers the whole of Greater London, which we allow for
Can you quote for a block close to Hackney Wick station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.
Do you supply RAMS and insurance details?
We’re CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Can you plan resealing across several buildings?
We can. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.
What about access for upper-floor joints?
Access is discussed and agreed before the quote is fixed. Tell us the building height and any access already in place, and we’ll tell you how we’d approach it.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
