Why act early in Willesden Green
A bead run over old mastic can look like a repair. It won’t grip the old sealant and soon comes away. Full removal and proper preparation is what lasts. In Willesden Green, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
We don’t publish prices, since every building and every scope is different. Call for a quote.

What sets the cost
To price the job, we consider:
- Backing rod, priming and other preparation
- Travel to remote or island sites
- How accessible the joints are
- Removal of failed or old sealant
Pricing mastic joints depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.
What we need to price the job
Diagnosis starts before we arrive. Let us know:
- What the building is and how it’s used
- The site address and postcode
- Any dates the work must fit around
- Clear photographs of the problem areas
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, ring 01277 525 020 or email the details over.
Aftercare for building managers
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Look at the sunniest and most exposed elevations first
- Ask residents or tenants to report leaks and draughts early
- Track which buildings were done and when
- Group repairs into a planned programme
Protect entrance and corridor joints from knocks where possible. Knocks cause many early failures in communal areas.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order so spending is spread.
FAQs: Willesden Green
Can you work in a London building with booked loading and goods-lift slots?
Yes, most London buildings have access rules of some kind, and we plan around them. Share the building’s contractor rules and we will work to them.
Can you work at a site such as Cumberland Business Park, by Willesden Green?
Yes. Estates, retail parks and business parks around Willesden Green, Cumberland Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Do you cover Willesden Green?
Yes. We cover Willesden Green, within our coverage of Greater London, South East England and Scotland. For a quote, ring 01277 525 020 or email the details over.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and we will price the work to it.
Is mastic sealing guaranteed?
Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Do you work for managing agents and housing associations?
Yes, that’s exactly who this service is for. Buildings are scheduled in turn so you can plan around it.
What we can’t put right
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Masonry that has broken away beside the joint
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Roof leaks, gutters or failed flashings that aren’t sealant joints
If you’re not sure, just call 01277 525 020 or use the quote form and we will give you a straight answer before you book.

Building owners, agents and FMs in Willesden Green
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Our process
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For a job in Willesden Green, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- First we look at the mastic on each building and note what needs replacing.
- You get a fixed quote, priced per building where that helps your budgeting.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Before we start on site
- Share the asbestos register for older buildings
- Explain the parking and delivery arrangements
- Let building users know which areas are affected
