Your questions answered

Can you work on a hospital site such as King's College Hospital?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

Can you work in a London building with booked loading and goods-lift slots?

Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. We allow for the ULEZ, which covers every borough

Can you send site paperwork?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

Is your workmanship covered by a guarantee?

Yes. The 12-month guarantee covers our preparation and application, though not damage or work by other trades.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

What will the job cost?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.

Do you offer coloured sealant?

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

Keeping the joints sound

Cleaning and maintenance staff play a part too. Share these points with them:

  • Record the product and colour used on each elevation
  • Check that rainwater leaves the facade the way it was designed to
  • Add perimeter sealant to planned maintenance checks
  • Avoid harsh cleaners on facade sealant

Record the sealant type and date on the building file. Future work can then match the product and colour without guesswork.

Use each reseal to correct the joint: correct depth, proper backing and a sealant that can take the movement. A well-designed joint lasts longer than a like-for-like copy of a failed one.

Surface by surface

Precast concrete panels

Concrete edges can be dusty or weak. Faces are cleaned to sound concrete, and damaged edges are reported.

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. Loose coatings are cleaned back first, and we’ll mention any edges that need repair.

Contractors’ notes for Dulwich Village

The area within 2 miles of Dulwich Village holds a good number of hotels. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included. The ULEZ covers the whole of Greater London, Dulwich Village included, so site vehicles need to meet its standards or pay the daily charge. Deliveries are booked and storage is tight, so mastic materials come in as needed.

Projects at colleges like William Booth College, 1.2 miles north of Dulwich Village, tend to run to term dates, so the mastic is planned tightly. Recladding or extending a unit at a site like Goose Green Trading Estate, 0.9 miles to the north-east of Dulwich Village, brings panel joints and frame perimeters into the programme. Projects at schools like Dulwich Hamlet Junior School work to term dates, so mastic is programmed tightly.

Why deal with it now?

Scaffold or access already on site makes resealing much simpler. Coordinating facade sealing with other external works avoids paying for access twice, which is often the biggest saving. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.

Doing it in-house

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

How a job runs

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. All of Greater London is in the ULEZ, and kerbside space in Dulwich Village can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  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.

Before we start on site

  • Move anything stored against the joints
  • Have the specification and drawings to hand
  • Share the asbestos register for older buildings
