Mastic sealing for commercial buildings in Brent Park
On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Entrances and stairwells are kept in use while we work. We work on balcony and threshold joints, communal kitchens and washrooms and communal entrances and stairwells, and what we’re called in for most is cracked, hardened mastic round windows on a block and mastic failing across several blocks on an estate. A single leaking joint is often how a building in Brent Park first comes to us: we look at the rest while we’re there and tell you what we find.
London has a large stock of purpose-built blocks, mansion flats and converted buildings managed by agents and housing associations. Window and door perimeters, balcony joints and communal areas all have mastic that ages together across a building, which is why block-wide programmes make sense.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Maintenance after handover
For the best life from the joints:
- Check sealant joints during planned building inspections
- List the paperwork your organisation requires when you send details
- Group repairs into a planned programme
- Prioritise elevations facing the weather
Log the date and extent of the resealing for each block. It helps plan the next round and gives you a history.
The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing and the job grows.
Why deal with it now?
Resealing ahead of leaks keeps it to a maintenance task. Once water has tracked in, the repair list grows and occupiers notice. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

When something else is needed
Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:
- Masonry that has broken away beside the joint
- Broken glass or failed sealed units
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
Not sure which it is? You can ring 01277 525 020 or send photos by email and we will tell you honestly before you book.
What we seal
- Communal kitchens and washrooms

Your questions answered
Will you take on a block within reach of Stonebridge Park station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Photos of each elevation help us quote accurately.
Do you cover business parks and estates near Brent Park, such as North Circular Business Park?
Yes. Our area takes in Brent Park and its surroundings, with estates and business parks such as North Circular Business Park included. A few photographs and the unit address let us price the work.
What if the old mastic contains asbestos?
Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Is mastic sealing guaranteed?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
What about access for upper-floor joints?
It depends on the building. We agree access with you at quote stage so the fixed quote reflects it.
Can you send RAMS and CSCS details before starting?
We are 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.

What the job involves on each surface
Commercial and mixed-use buildings
Where retail and residential share a building the programme has to suit everyone. We plan around the site hours and access windows you give us.
Planned maintenance
How long mastic lasts depends on exposure, movement and the product used. Regular inspection is the best way to plan resealing.
Commercial clients in Brent Park
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
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, and each stage is agreed with your contact.
On site: what to expect
At the end of each section, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. All of Greater London is in the ULEZ, and kerbside space in Brent Park can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- Each block or building is walked and the failed joints recorded with the likely cause.
- You get a fixed quote, priced per building where that helps your budgeting.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Explain the parking and delivery arrangements
- Flag any permit to work we’ll need
