Mastic sealing in Old Oak Common, done properly
Managing agents and housing associations usually need paperwork before anyone starts. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are a Constructionline member and CHAS accredited, and we carry public liability insurance. The enquiries we see most involve leaks at window and door perimeters and draughts at frames across a block, on balcony and threshold joints, external wall and movement joints and communal entrances and stairwells. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Old Oak Common is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Planning mastic work on a London block means notices to residents, access to flats and agreed working areas. Work is planned with the agent so residents get notice and access is arranged in advance.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Signs you need mastic sealing in Old Oak Common
Topping up old mastic is a common shortcut. New silicone has nothing to grip on old silicone, so these repairs rarely last.
If one of these sounds familiar, it’s time for a closer look:
- Estate-wide sealant that is simply worn out
- Repeated reactive repairs to the same buildings
- Occupiers reporting cold air round windows
- Communal area joints that look neglected
Older community buildings, Church of Eritrean Orthodox Brent among them, often have frames of mixed ages whose mastic varies.
What your quote should include
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Which product they’ll use, and why it suits the joint
- Do they follow the manufacturer’s priming guidance?
- Whether their applicators hold CSCS cards
Should maintenance staff do it?
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Looking after the joints
Cleaning and maintenance staff play a part too. Pass these on to them:
- Mention RAMS, insurance or CSCS requirements up front
- Plan resealing building by building rather than complaint by complaint
- Share the asbestos register when you send details
- Reduce knocks to communal area joints
Encourage occupiers to report water or draughts at frames. Early reports catch failures before damage spreads.
Joints on a building age together so a single failure is a sign to check the rest. Doing them together saves going back again and again.
When it isn’t the sealant
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:
- Broken glass or failed sealed units
- Leaks from above rather than through a joint
- Leaks through the frame itself rather than the perimeter
Not sure which it is? You can call 01277 525 020 or send details through our quote form and we will tell you honestly.
Surfaces we seal
- Communal kitchens and washrooms
- Balcony and threshold joints

- Shopfronts below residential blocks

Can you work in a London building with booked loading and goods-lift slots?
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
Can you reseal a whole block or estate?
Yes, planned programmes suit estates and portfolios. You get a fixed quote per building or for the whole job.
Do you work with property factors and landlords?
Yes, block and estate work is a core part of what we do. We work through buildings in a planned order with dates agreed in advance.
When is resealing likely to be due?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
How do you reach windows on upper floors?
Every block is different. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.
How much does the work cost?
Every job gets its own fixed quote. For yours, call the office on 01277 525 020 or send photos by email with a description of the work.
