Need facade sealing in Camberwell?

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

How the quote is worked out

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

  • The total length or number of joints
  • How accessible the joints are
  • Site requirements such as inductions and permits
  • Whether the work must be split into stages

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

Sending details for a quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • Rough lengths or quantities, or drawings if you have them
  • The postcode of the building
  • Asbestos survey details if the building is older
  • Any dates the work must fit around

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

About our facade sealing in Camberwell

External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits, so frosty or damp mornings can hold work back. We plan for that and keep you updated. Site teams most often ask us about hard, chalky sealant that no longer flexes and failed seals around shopfront and entrance frames, across shopfront frames, window and door perimeters and coping and flashing joints. Looking for mastic applicators who cover Camberwell? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

Every London site, Camberwell included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Camberwell: questions and answers

Do you work in London buildings with loading restrictions?

Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we will work to them. The ULEZ covers the whole of Greater London, which we allow for

Is a hospital such as Maudsley Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is colour matching possible?

That depends on the product specified. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.

Can you work on upper floors?

Access is planned with you before we quote. Tell us about access: existing scaffold, what you are arranging and any site restrictions, and the quote will reflect it.

Can one quote cover more than one building?

Yes. Several buildings can share a single quote, with one point of contact.

How long does a typical visit take?

We plan the time on site around your programme and access. You’ll have an expected duration with the quote.

Do you hold CHAS accreditation?

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

After the work

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Insist on a full cut-out when joints are renewed
  • Plan facade sealing alongside redecoration
  • Avoid harsh cleaners on facade sealant
  • Check that rainwater leaves the facade the way it was designed to

Following storms, look inside for damp or staining near frames. An early report usually means a small reseal rather than a bigger repair.

Deal with sections that fail early as soon as they show. A few metres resealed promptly can stop water damage spreading inside the building.

What we’re called out for in Camberwell

When sealant lets go of a frame or panel, the cause is often the preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond.

Site and facilities staff are often the first to spot these:

  • Weathered joints at frame-to-structure perimeters
  • Failed sealant on precast panel joints
  • Old perimeter mastic that has dried out
  • Staining on stone next to old sealant

Units on estates such as Valmar Trading Estate, less than half a mile south-west of Camberwell, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

What to look for in a quote

  • Their pre-qualification and accreditations
  • How they handle RAMS and site documents
  • Who will actually carry out the work
  • What level of public liability insurance do they hold?

Questions to ask before you appoint anyone

New build and refits around Camberwell

Site traffic in Camberwell falls within London’s ULEZ, like everywhere else in Greater London. Add booked deliveries and tight storage, and the mastic package needs planning with the site team. There are a good number of hotels within about 2 miles of Camberwell. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight.

For a contractor working at a hospital such as Maudsley Hospital (under half a mile south of Camberwell), perimeter and facade sealing is planned around patients and deliveries. When a college such as Southwark College (to the north-east of Camberwell) builds or refurbishes, the mastic package normally has to fit around students and staff.

Camberwell is about 2 miles south of London, in Greater London. We cover Camberwell, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Camberwell is one of 764 places in Greater London on our list for facade joints.

What the job involves on each surface

Coping and flashing joints

Sometimes the coping or flashing itself has failed. Where the issue isn’t the sealant, we say so.

Cladding panel joints

Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish.

Doing it in-house

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

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.

Our process

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For a job in Camberwell, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.

  1. Access, site rules and timing are settled with the client up front.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. We hand over with our 12-month workmanship guarantee.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Tell us your opening times and when work is allowed
  • Let building users know which areas are affected
