Facade sealing for Tokyngton sites

About our facade sealing in Tokyngton

Sealant around windows, doors and cladding panels stops rain reaching the wall behind. Once a perimeter seal fails, water tracks in around frames and panels. We remove failed sealant and install a new bead chosen for the joint and how far it moves. Site teams most often ask us about previous reseals run over old sealant and old perimeter mastic that has dried out, on perimeter joints where frames meet the structure, window and door perimeters and coping and flashing joints. For commercial sealant work in Tokyngton, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building, so tidy, well-planned work matters.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or email a schedule or drawings and we’ll come back to it.

For managing agents and facilities managers

When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Common questions from Tokyngton clients

Will you take on work at estates like Wembley Stadium Industrial Estate, close to Tokyngton?

Yes. We cover Tokyngton and the area around it, including industrial estates, business parks and retail parks such as Wembley Stadium Industrial Estate. A few photographs and the unit address let us price the work.

Can you work around term dates at a campus such as University of West London?

Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is the work guaranteed?

Yes. Our workmanship is backed for 12 months.

Can you fit around our working hours?

Give us your site hours and any access windows in your enquiry, and we’ll plan around them. Our office runs Monday to Friday, 8am until 5pm.

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

Can you look at water coming in around a frame?

Yes. Photos help, and you can speak to us on 01277 525 020 or send details through our quote form to arrange a visit. Many frame leaks are sealant failures, though not all.

Why deal with it now?

Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Leaks travel along the structure. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.

A quote for facade joints depends on quantities, condition and access, plus any specification you are working to. Call for a quote.

Why appoint us

  • Joints cleaned back to sound surfaces
  • Public liability insurance in place
  • CHAS accredited contractor
  • Standard and matched colours in many product ranges

Building and refurbishing in Tokyngton

As part of Greater London, Tokyngton is inside the ULEZ, which applies to every van on site. Deliveries are booked and storage is tight, so mastic materials come in as needed. There are a good number of hotels within about 2 miles of Tokyngton. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.

When units on a site such as Wembley Stadium Industrial Estate, 0.8 miles to the north of Tokyngton, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. For a contractor working at a hospital such as Central Middlesex Hospital, which lies south of Tokyngton, perimeter and facade sealing is planned around patients and deliveries. On a campus such as University of West London, which lies south-west of Tokyngton, new teaching buildings and residences are typically built and refurbished around the academic year.

Tokyngton is about 1 mile south-east of Wembley, in Greater London. Any commercial site in Tokyngton is covered. Our Greater London coverage takes in 764 places, large and small. There’s a separate page for London, roughly 9 miles from Tokyngton.

When it isn’t the sealant

We check first that sealant really is the fix. It won’t put right:

  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Installing or repairing glazing systems
  • Cracked or spalling substrates that need repair before sealing

Not sure which it is? You can call the office on 01277 525 020 or send details through our quote form and we’ll tell you honestly.

Joints and surfaces we work on

  • Window and door perimeters
  • Coping and flashing joints
  • Perimeter joints where frames meet the structure
  • Cladding panel joints
  • Stone and brick facade joints
  • Shopfront frames

Doing it in-house

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

How the job changes by surface

Precast concrete panels

Joints between precast panels carry real movement. A sealant of the right movement class goes in over backing rod, primed where the maker specifies.

Render and coated surfaces

Paintable sealants exist for joints that will be coated. We confirm the product with you before starting.

On site: what to expect

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. In Tokyngton, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.

  1. We plan access and the order of elevations with the client.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. Each joint is cut out and the edges inspected.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. Once signed off, the work carries our 12-month guarantee.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Point out any areas we must not close
  • Move anything stored against the joints
