Facade sealing for businesses in North Wembley

Different surfaces, different methods
Cladding panel joints
Panel joints on cladding and rainscreen systems take movement every day. We use a product rated for the movement and suited to the panel surface, as the specification sets out.
Coping and flashing joints
Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building and need a durable external sealant.
Facade sealing for commercial buildings in North Wembley
External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits, and cold, damp starts can delay work. We build that into the programme and tell you if the forecast changes the plan. Site teams most often ask us about air leaks through failed facade joints and leaks at window and door perimeters, across window and door perimeters, coping and flashing joints and shopfront frames. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in North Wembley, that means joint design, primers and backing rod as standard.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by, so tidy, well-planned work matters.
Work we carry out in Greater London comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or email a schedule or drawings and we will arrange a return visit.

How a job runs
Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. For a job in North Wembley, access comes first. Give us the hours we can be on site and we will schedule to suit.
- We plan access and the order of elevations with the client.
- 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.
Before we start on site
- Confirm the product named in the specification
- Let building users know which areas are affected
- Make sure the joints can be reached

Advice
Work for main contractors and building owners
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.
What sealant work can’t fix
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Installing or repairing glazing systems
- Water getting in through cracked render or porous masonry
- Render or concrete edges that have broken away
If you’re not sure, just phone 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.

Building and refurbishing in North Wembley
The area within 2 miles of North Wembley holds plenty of hotels. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included. As part of Greater London, North Wembley is inside the ULEZ, which applies to every van on site. Delivery slots and scarce storage shape how and when the mastic goes in.
When units on a site such as East Lane Business Park (to the north of North Wembley) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. For a contractor at a hotel such as Euro Hotel Wembley, under half a mile south-east of North Wembley, the mastic often has to be finished before a reopening date.

Quoting for work in North Wembley
Each job is priced on its own details. The main factors are:
- Whether old sealant has to be cut out first
- The size and state of each joint
- Travel to remote or island sites
- Quantities, in metres or numbers
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
What to include in your enquiry
To price the job accurately, we need a clear picture of the site. Send us:
- When you need the work done
- Anything awkward about access or site hours
- Asbestos survey details if the building is older
- Drawings or a marked-up plan, if available
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, call the office on 01277 525 020 or email us.
What we are called out for in North Wembley
Sun, rain and temperature swings wear facade sealant down over the years. UV and weather harden the sealant until it can’t stretch with the building, then it splits or peels.
It’s worth sending us details if you spot any of the following:
- Failed seals around shopfront and entrance frames
- Cold air coming in at window perimeters
- Weathered facade joints that have lost their grip
- Failed sealant on precast panel joints
Building work at universities like Westminster University (1.7 miles north-west of North Wembley) is often timed for the summer, mastic included.
What your quote should include
- Will RAMS and insurance details be available?
- Their pre-qualification and accreditations
- Will CSCS-carded applicators be on site?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
Questions we’re asked in North Wembley
Could you schedule work at a campus like Westminster University for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Do you take on jobs in North Wembley where loading and access are tightly controlled?
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. The ULEZ covers the whole of Greater London, which we allow for
Will you check whether the sealant is causing the leak?
Yes. We look at the perimeter sealant and tell you whether it has failed before quoting. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.
Do your applicators hold CSCS cards?
Yes. If you need card details for site access, let us know and we will send them with the quote.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
Do you need to see the site first?
That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
How long does a typical visit take?
That varies with the scale of the job, though a typical visit usually takes anything from a single day to several weeks, depending on joint lengths, access and the weather. For bigger or phased jobs, we’ll set out a timescale with the quote.
