Facade sealing near Bellingham

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

When it isn’t the sealant

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Damaged frames that need replacing
  • Work on the window or framing system itself
  • Joints too narrow for the movement they take, which need redesign

If you’re not sure, just speak to us on 01277 525 020 or use the quote form and we’ll give you a straight answer.

Joints and surfaces we work on

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

Facade sealing for commercial buildings in Bellingham

Weather decides a lot in facade sealing. Joints have to be dry and the air and surface temperature within the product’s range. We plan for that and keep you updated. Site teams most often ask us about perimeter sealant that has split or peeled away and gaps between rainscreen or cladding panels, on coping and flashing joints, cladding panel joints and window and door perimeters. Whoever orders the work in Bellingham, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Bellingham must meet its standards or pay the daily charge. Alongside that, sites normally need booked deliveries and a plan for where materials go.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant.

Your questions answered

Is hospital work, at somewhere like University Hospital Lewisham, something you do?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Is Bell Green Retail Park, near Bellingham, within your area?

Yes. Our area takes in Bellingham and its surroundings, with estates and business parks such as Bell Green Retail Park included. A few photos and the unit address let us price the work.

Do you use silicone for external joints?

Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, as the specification or substrate requires.

Does weather matter for sealant work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Is Bellingham in your area?

Yes. We cover Bellingham, and the simplest way to start is to call 01277 525 020 or send photos by email.

Do you provide access for facade work?

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 you quote from photos?

Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

Our process

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. 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. First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Getting the site ready

  • Let building users know which areas are affected
  • Arrange parking or a loading space
  • Point out any areas we must not close

How the job changes by surface

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.

Precast concrete panels

Precast arrises sometimes crumble or carry old residue. We clean back to sound material and flag edges that need repair.

Keeping the joints sound

Keep the joints in good shape with a few simple steps:

  • Record the product and colour used on each elevation
  • Keep sills, gutters and drainage paths clear
  • Avoid patch repairs on failed facade joints
  • Avoid harsh cleaners on facade sealant

Hold back any cleaning crew until the joints have had their stated cure time. Keep high-pressure jets and strong chemicals away from new sealant, so brief your window cleaners.

Building facade joints into a maintenance cycle avoids emergency repairs. Inspect regularly and reseal sections as they start to fail.

Sites and facades in and around Bellingham

The ULEZ covers the whole of Greater London, Bellingham included, so site vehicles need to meet its standards or pay the daily charge. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. Bellingham has several hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.

University estates such as University of Greenwich - Greenwich Campus, 3.6 miles north of Bellingham, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. For contractors at a college like Capel Manor College, which lies south-west of Bellingham, perimeters and internal sealant are timed for the holidays. New units and refits on sites such as Bell Green Retail Park (under half a mile west of Bellingham) need their panel and perimeter joints sealed to the specification.

How the quote is worked out

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

  • Quantities, in metres or numbers
  • Which sealant the job calls for
  • Whether the work must be split into stages
  • Backing rod, priming and other preparation

There’s no price list, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

What we need to price the job

Diagnosis starts before we arrive. Tell us:

  • The product your specification calls for
  • What the building is and how it’s used
  • The site address and postcode
  • The asbestos register, for older buildings

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to call the office on 01277 525 020 or send details through our quote form.
