Mastic sealing for commercial buildings in Lea Bridge
We diagnose before we prescribe: which joints have failed, why, and whether sealant is the right answer. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed, with backing rod setting the depth where it’s needed. If you have brittle perimeter mastic across a building and leaks at window and door perimeters, we can help. Looking for mastic applicators who cover Lea Bridge? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
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.
Our workmanship is guaranteed for 12 months, in Lea Bridge as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

How a job runs
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. For a job in Lea Bridge, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. 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.
- A fixed quote covers the joints, products and order of work.
- Failed mastic is removed completely.
- The joints are prepared and resealed with the right product.
- Buildings are completed in turn.
Before we start on site
- Move anything stored against the joints
- Warn occupants and staff about the work
- Confirm the product named in the specification

Leave it or put it right?
Open external joints let water into walls and around frames. Damp patches, stained plaster and decorating claims can follow and those cost far more to put right. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Why clients in Lea Bridge choose us

Common reasons buildings call us in:

- No planned programme for sealant
- Open joints in brickwork or panels

What the job involves on each surface

We typically work through a block’s windows in a planned order. Access is agreed with you before the quote is fixed.
Common questions from Lea Bridge clients
Will you take on a block within reach of Clapton station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.
Can you work at a site such as Eastgate Business Park, by Lea Bridge?
Yes, sites like Eastgate Business Park are within our area, along with the rest of Lea Bridge. A few photos and the unit address let us price the work.
Do you seal on top of existing sealant?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Do you check for asbestos in old sealant?
We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and we will price the work to it.
Can you take on resealing for a block portfolio?
Yes, that’s exactly who this service is for. Buildings are scheduled in turn so you can plan around it.
After the work
Regular inspection catches problems early. Specifically:
- Check the asbestos register before any old mastic is disturbed
- List the paperwork your organisation requires when you send details
- Group repairs into a planned programme
- Look at the sunniest and most exposed elevations first
If paintable sealant was used, decoration can follow once it has cured. Non-paintable silicone shouldn’t be painted over unless told otherwise.
Joints on a building age together so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
