Questions about Stoke Newington
Will you take on work at estates like Frogmore Industrial Estate, close to Stoke Newington?
Yes. Our area takes in Stoke Newington and its surroundings, with estates and business parks such as Frogmore Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we will plan accordingly.
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.
Do you need to see the site first?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs typically get a visit.
What if the old mastic contains asbestos?
We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
Is any job too small?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Can you take on resealing for a block portfolio?
Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.
Mastic sealing in Stoke Newington
Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Every applicator holds a CSCS card, and the work is backed by public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. Most enquiries involve the same joint failures repeated across a portfolio and movement joints with sealant missing, on window and door perimeters on blocks, shopfronts below residential blocks and external wall and movement joints. A specialist sealant contractor works differently from a general builder: on jobs in Stoke Newington, preparation and product choice get the time they need.
Across Greater London, Stoke Newington included, the ULEZ applies, and parking and loading rules differ from street to street. For block-wide work, a place to park and store materials saves time on every visit.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Common problems we fix in Stoke Newington
Sunlight and weather break mastic down over time. It stiffens, stops stretching and cracks, especially on south and west faces.
Clients typically get in touch after noticing something like this:
- Damaged joints in communal entrances and corridors
- No planned programme for sealant
- Open joints in brickwork or panels
- Draughts at frames across a block
Trustees of buildings like Old Church of St Mary can bring frame and external mastic into a planned maintenance list.

Doing it in-house
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Building owners, agents and FMs in Stoke Newington
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
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, with each stage agreed with your site contact.

Aftercare for building managers
After handover, a little attention goes a long way:
- Check the asbestos register before any old mastic is disturbed
- Protect low-level joints in entrances
- Make it easy for occupiers to report draughts
- Group repairs into a planned programme
Encourage occupiers to report water or draughts at frames. Early reports catch failures before damage spreads.
Leaks at window perimeters spoil finishes and can affect frames. Early resealing is far simpler than repairs inside.

What the job involves on each surface
Window and door perimeters on blocks
On most blocks, the frame-to-wall joint is where failure shows first. We remove the failed mastic, prepare the faces, add backing rod if the joint is deep and reseal.
Communal areas
Communal entrances, stairwells and corridors have joints at door frames, screens, skirting and floor edges. Tidy, sound joints keep them looking cared for.
