How we handle facade sealing in Jarvis Brook

Weather decides a lot in facade sealing. Joints have to be dry and the air and surface temperature within the product’s range, so frosty or damp mornings can hold work back. We build that into the programme and tell you if the forecast changes the plan. Site teams most often ask us about hard, chalky sealant that no longer flexes and staining on stone next to old sealant, on shopfront frames, perimeter joints where frames meet the structure and stone and brick facade joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Jarvis Brook, preparation and product choice get the time they need.

Construction in and around smaller places such as Jarvis Brook is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

What sets the cost

Your fixed quote is built from the real scope. It allows for:

  • Working within restricted access windows
  • Site requirements such as inductions and permits
  • How much there is to seal
  • The product specified

The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Before you send an enquiry

Good information means a firmer quote. Helpful details to send:

  • How the joints are reached, and at what height
  • When you need the work done
  • Whether an asbestos survey exists
  • Any specification or named product

The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or give us a call on 01277 525 020 or email drawings and photos to discuss it first.

Maintenance after handover

Regular inspection catches problems early. In particular:

  • Add perimeter sealant to planned maintenance checks
  • Combine resealing with other works that need access
  • Clear debris that holds water against joints
  • Record the product and colour used on each elevation

Look at perimeter and panel joints as part of routine building checks. Watch for splits, gaps at the edges, hardening and discolouration; note where they appear.

Don’t wait for a full elevation to fail. Small repairs stop small leaks becoming large ones behind the facade.

From enquiry to sign-off

Working in a building that stays open takes some planning. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Jobs in and around smaller places like Jarvis Brook are normally planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full and the joint faces cleaned.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. We go over the completed work with you before leaving.

Before we start on site

  • Tell us which areas need to stay in use
  • Let us know about inductions and permits
  • Confirm the product named in the specification

Common problems we fix in Jarvis Brook

Adhesive failure, where the sealant peels away from one face, typically comes from poor preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly, and movement soon pulls it away.

Any of the following is a good reason to get the joints checked over:

  • Perimeter joints where frames meet the structure
  • Weathered facade joints that have lost their grip
  • New sealant peeling off old mastic
  • Gaps between rainscreen or cladding panels

Units on estates such as Lexden Lodge Industrial Estate (less than half a mile south-east of Jarvis Brook) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Comparing quotes

  • Will CSCS-carded applicators be on site?
  • Health and safety accreditation such as CHAS
  • Is the sealant right for the movement and the substrate?
  • Can the work be phased to keep areas open?

Our contractor checklist

For managing agents and facilities managers

We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.

Jarvis Brook: questions and answers

Is a hospital such as Crowborough War Memorial Hospital somewhere you can work?

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.

Can you work at a site such as Lexden Lodge Industrial Estate, by Jarvis Brook?

Yes. Our area takes in Jarvis Brook and its surroundings, with estates and business parks such as Lexden Lodge Industrial Estate included. A few photos and the unit address let us price the work.

Can the building stay open while you work?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

Can you handle several sites?

Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

Do you offer coloured sealant?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

Surface by surface

Perimeter joints at frames and structure

Perimeter joints at frames often show their age first. We cut them out, prepare both faces and reseal to the specification with a product suited to glazing perimeters.

Render and coated surfaces

Sealant can only hold as well as the render or paint beneath it. Loose coatings are cleaned back first, and we will mention any edges that need repair.

Facades, frames and programmes in Jarvis Brook

Jarvis Brook lies roughly 33 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme. Jarvis Brook sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager.

When a school such as Jarvis Brook Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. For a contractor working at a hospital such as Crowborough War Memorial Hospital (1.3 miles west of Jarvis Brook), perimeter and facade sealing is planned around patients and deliveries.
