New build and refits around Neasden
The area within 2 miles of Neasden holds plenty of hotels. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight. Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Neasden. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.
Recladding or extending a unit at a site like Falcon Park Industrial Estate (under half a mile west of Neasden) brings panel joints and frame perimeters into the programme. When a college such as College of North West London, less than half a mile to the south of Neasden, builds or refurbishes, the mastic package typically has to fit around students and staff.

Facade sealing in Neasden
Access is part of every facade job, and we plan it with you before quoting. Let us know what access exists or is planned, and any site rules we need to work around, and we’ll fit the work around it. We work on cladding panel joints, coping and flashing joints and perimeter joints where frames meet the structure, and the failures we are asked to look at most are draughts around frames and panels and cladding panel joints that have opened up. A single leaking joint is often how a building in Neasden first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Construction in a London area such as Neasden means working on constrained sites: limited storage, booked deliveries and access shared with other trades. We fit around the programme, sealing each elevation or floor as other trades hand over.
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 are upfront about that.

Signs you need facade sealing in Neasden
When sealant lets go of a frame or panel, the cause is often the preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly.
What tends to prompt an enquiry:
- Gaps between rainscreen or cladding panels
- Hard, chalky sealant that no longer flexes
- Weathered joints at frame-to-structure perimeters
- New sealant peeling off old mastic
Extensions at sites like Central Middlesex Hospital (to the south-west of Neasden) normally sit beside working departments, and the mastic follows strict access rules.

- Their plan for phasing and protecting the area
- How the joint faces will be prepared and primed
- Whether old or failed sealant will be cut out, not overlaid
When to bring in a specialist
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
How the quote is worked out
Before we quote, we look at:
- Distance, for remote addresses
- Phasing around occupants
- The product specified
- How much there is to seal
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.
Before you send an enquiry
We can often quote from photographs and a few details. Please tell us:
- When you need the work done
- Where the site is, with the postcode
- Approximate linear metres or a joint schedule
- Whether an asbestos survey exists
Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, give us a call on 01277 525 020 or send details through our quote form.
Work for main contractors and building owners
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Neasden can form part of a wider programme.
Diagnose, treat, sign off
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before we move to the next. Planning a London job such as one in Neasden starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we will schedule to suit.
- Access, site rules and timing are settled with the client up front.
- Weather and temperature are checked against the product’s limits.
- Each joint is cut out and the edges inspected.
- Joints are cleaned, primed if required and fitted with backing rod.
- Sealant is gunned in and tooled hard onto both faces.
- We hand over with our 12-month workmanship guarantee.
What we need from you
- Move anything stored against the joints
- Send any specification or drawings in advance
- Tell us what induction or permit system the site runs

What we can’t put right
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Joints too narrow for the movement they take, which need redesign
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Specialist high-level access methods
If you’re not sure, just call 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.
