About our facade sealing in West Silvertown

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 will fit the work around it. Site teams most often ask us about hard, chalky sealant that no longer flexes and failed sealant on precast panel joints, across cladding panel joints, perimeter joints where frames meet the structure and coping and flashing joints. For commercial sealant work in West Silvertown, 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.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

How the quote is worked out

The price varies from site to site. It mainly depends on:

  • Quantities, in metres or numbers
  • How much existing material needs removing
  • Induction, permit and paperwork requirements
  • Working within restricted access windows

Pricing facade joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

Before you send an enquiry

The more we know, the firmer the quote. When you get in touch, include:

  • Rough lengths or quantities, or drawings if you have them
  • Where the site is, with the postcode
  • What the building is and how it’s used
  • Clear photos of the problem areas

The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or phone 01277 525 020 or email the details over to discuss it first.

After the work

For the best life from the joints:

  • Check that rainwater leaves the facade the way it was designed to
  • Note when each elevation was last resealed
  • Share access with other external trades
  • Walk the elevations once or twice a year

Anything drilled through a facade joint breaks the seal. Make sure the joint is resealed afterwards with a compatible product.

Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail, rather than waiting for a ceiling stain.

Signs you need facade sealing in West Silvertown

Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.

Clients normally get in touch after noticing one or more of the following:

  • Air leaks through failed facade joints
  • Sealant pulling away from frames or panels
  • Unsightly perimeter sealant on a visible elevation
  • Cladding panel joints that have opened up

When units on a site such as Greenshields Industrial Estate, under half a mile to the south-west of West Silvertown, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Before you book anyone

  • What level of public liability insurance do they hold?
  • Their pre-qualification and accreditations
  • What the guarantee covers, and for how long

Choosing a commercial sealant contractor

General trades versus a specialist

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Facade sealing in West Silvertown: the local picture

As part of Greater London, West Silvertown is inside the ULEZ, which applies to every van on site. Delivery slots and scarce storage shape how and when the mastic goes in. West Silvertown has a good number of hotels close by, all within 2 miles. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.

On a healthcare site such as Newham University Hospital, 1.4 miles north of West Silvertown, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. For contractors on a campus like Ravensbourne University London, 0.8 miles to the west of West Silvertown, facade and perimeter sealing has to fit around students and term dates.

When it isn’t the sealant

Honesty saves time and money. New sealant won’t cure:

  • Joints whose design needs changing by the specifier
  • Installing or repairing glazing systems
  • Cracked or spalling substrates that need repair before sealing

If in doubt, ring 01277 525 020 or send photos by email and we’ll say what we think before you book.

Surfaces we seal

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

Our process

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. Product choice follows the joint’s movement and substrate.
  3. Failed beads are removed in full and both faces cleaned back.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

What we need from you

  • Have the specification and drawings to hand
  • Send asbestos survey details if the building is pre-2000
  • Send your site hours and access windows
