Construction mastic for commercial buildings in Cricklewood
We work to the specification and the programme. If a product is named, that’s what goes in. Joint widths, backing, primers and tooling follow the manufacturer’s guidance, so the joints perform as the designer intended. If you’re dealing with external joints sealed in damp or cold conditions that are now failing and failed sealant in an existing building being refurbished, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Cricklewood is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around Cricklewood, as across London, much of the work is refurbishing existing buildings as well as building new ones. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by, so tidy, well-planned work matters.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Our process
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes, and our waste is bagged and taken away as we go. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- Drawings, the sealant specification and your programme come to us for pricing.
- You receive a fixed quote listing scope, products and phasing.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- We close out snagging and hand over with a 12-month guarantee.
Getting the site ready
- Send asbestos survey details if the building is pre-2000
- Warn occupants and staff about the work
- Send any specification or drawings in advance

Questions about Cricklewood
Would you work within a site like Royal Free Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Will you take on work at estates like The Quadrant Business Centre, close to Cricklewood?
Yes. Our area takes in Cricklewood and its surroundings, with estates and business parks such as The Quadrant Business Centre included. A few photographs and the unit address let us price the work.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also call 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.
Do you have public liability insurance?
Yes. We’re fully insured, and the certificate can go with your quote.
Can one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Why it’s worth doing now in Cricklewood
It helps to bring the mastic subcontractor in before the package is urgent. Early involvement means gaps, products and access are sorted before the programme bites, which avoids last-minute problems. Called in at the end, the same issues surface during handover. In Cricklewood, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

For managing agents and facilities managers
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Cricklewood can form part of a wider programme.
After the work
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Release areas for mastic once other trades have finished in them
- Brief following trades on areas that have been sealed
- Stick to the specified sealant rather than a generic substitute
- Note which sealant went where at handover
At handover, keep the product details with the O&M information. Future maintenance is easier when the products are known and avoids guesswork when joints are renewed. We can confirm the handover information you need when we quote.
Leaving the mastic snag list to the end squeezes everyone. A planned close-out through each area as it completes keeps the list short, and avoids a rush.
What affects the price in Cricklewood
What shapes the price:
- Site requirements such as inductions and permits
- The product specified
- How accessible the joints are
- Whether old sealant has to be cut out first
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.
Sending details for a quote
There’s no need for a formal survey. A few details are enough to get going:
- Approximate linear metres or a joint schedule
- Where the site is, with the postcode
- Any dates the work must fit around
- Clear photos of the problem areas
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

When to call us in Cricklewood
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We stick to the specified product, or put any alternative to you first.
Most enquiries start with one or more of the following:
- Oversized or tapered gaps around new frames
- Window and door perimeters that won’t pass inspection
- New external sealant already peeling away
- Snag items on joints that need redoing before handover
For a contractor at a hotel such as The Crown Moran Hotel, less than half a mile to the north-east of Cricklewood, the mastic often has to be finished before a reopening date.
Questions to ask before you book
- Proof of insurance

- Whether primer will be used where the manufacturer specifies it
- How the existing material will be dealt with
