About our mastic sealing in Burnt Oak
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. We work on window and door perimeters on blocks, shopfronts below residential blocks and communal entrances and stairwells, and what we’re called in for most is cracked, hardened mastic round windows on a block and draughts at frames across a block. Whether you call it commercial sealant work, mastic application or joint sealing, in Burnt Oak it comes down to the same thing: the right product in a properly prepared joint.
For managing agents in Burnt Oak, resident access, notice periods and the building’s rules shape the job. Work is planned with the agent so residents get notice and access is arranged in advance.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

What affects the price in Burnt Oak
What shapes the price:
- The site’s rules and procedures
- Whether the work must be split into stages
- The product specified
- How accessible the joints are
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Sending details for a quote
The more we know, the firmer the quote. Helpful details to send:
- Asbestos survey details if the building is older
- Clear photographs of the problem areas
- Approximate linear metres or a joint schedule
- The postcode of the building
To get a fixed quote, speak to us on 01277 525 020 or send photos by email with the site address and an outline of the work. Our quote form is another easy route.
Looking after the joints
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- List the paperwork your organisation requires when you send details
- Prioritise elevations facing the weather
- Encourage occupiers to report problems at frames
- Keep a record of when each building was resealed
Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.
Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.
Common questions from Burnt Oak clients
Will you take on work at estates like Mill Hill Industrial Estate, close to Burnt Oak?
Yes. Estates, retail parks and business parks around Burnt Oak, Mill Hill Industrial Estate among them, are all within reach. To start, just give us a call on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Can you cope with the access rules in a London building?
Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough
What do you charge?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we’ll price it properly.
When is resealing likely to be due?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
How do you handle work on occupied blocks?
We plan around people living or working in the building. We agree the programme so you can notify occupiers, and entrances stay in use.
Do you supply RAMS and insurance details?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.
Can you take on resealing for a block portfolio?
Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn so you can plan around it.
What happens if it’s left?
Sealing over failed mastic looks tidy for a while. It doesn’t bond and usually fails within a short time. Cutting out and resealing properly does it once. In Burnt Oak, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.

- Window mastic that has split and shrunk
- Worn sealant at communal door frames
Landlords with units on estates such as Mill Hill Industrial Estate (0.6 miles east of Burnt Oak) can bring frame, door and external mastic across several units into one programme.
