How we handle facade sealing in Higham

We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure for clients around Higham. Coping and flashing joints are included where sealant is the specified fix. We work on shopfront frames, stone and brick facade joints and window and door perimeters, and what we are called in for most is old perimeter mastic that has dried out and patch repairs that keep failing. Whether you call it commercial sealant work, mastic application or joint sealing, in Higham it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Conversions of older rural buildings near smaller places such as Higham bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is usually what’s needed.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Contractors’ notes for Higham

Higham lies roughly 24 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme. The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack.

University estates such as University for the Creative Arts - Rochester, 3.5 miles to the south-east of Higham, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. When units on a site such as Nuralite Industrial Estate, 1.6 miles north of Higham, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Higham is about 2 miles north-west of Rochester, in Kent. Looking for facade sealing in Higham? We can help, as we do across Kent. Higham is one of 931 places we cover in Kent for facade joints. London is covered too, some 24 miles away.

Higham: questions and answers

Will you plan work around the academic year at somewhere like University for the Creative Arts - Rochester?

Yes. We plan campus work around teaching, exams and residence turnarounds. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Can you work on a hospital site such as French Hospital?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Do you seal facades in winter?

Wet joints or temperatures outside the product’s range mean waiting. The programme allows for it and we tell you if the forecast changes things.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.

Can you quote from photos?

It depends on the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs typically get a visit.

Do you offer coloured sealant?

It depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

Should we check old sealant for asbestos?

It’s worth checking in any building from before 2000. The duty to manage asbestos sits with the dutyholder, and we’ll ask to see it. If asbestos is suspected, work stops until it is tested.

Different surfaces, different methods

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. We remove flaking material so the bead bonds to a firm surface, and areas needing repair are flagged.

Cladding panel joints

Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish, as the specification sets out.

How a job runs

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. For a building around Higham, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. We plan access and the order of elevations with the client.
  2. Weather and temperature are checked against the product’s limits.
  3. Each joint is cut out and the edges inspected.
  4. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

Getting the site ready

  • Move anything stored against the joints
  • Let building users know which areas are affected

What we are called out for in Higham

Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.

Typical triggers for a call:

  • Perimeter sealant that has split or peeled away
  • Cladding panel joints that have opened up
  • Staining on stone next to old sealant
  • Draughts around frames and panels

Extensions at sites like French Hospital, 2.8 miles to the south-east of Higham, usually sit beside working departments, and the mastic follows strict access rules.

What to look for in a quote

  • Do they follow the manufacturer’s priming guidance?
  • The named product and why it was chosen
  • What the guarantee covers, and for how long
  • Their plan for phasing and protecting the area

Choosing a commercial sealant contractor

Honest limits

Being straight saves everyone time. Fresh joints won’t solve:

  • Damaged frames that need replacing
  • Work on the window or framing system itself
  • Arranging specialist high-level access, which is planned with the client

If you are not sure, just call the office on 01277 525 020 or send photos by email and we will give you a straight answer before you book.

Surfaces we seal

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

Cost factors for facade joints

Quotes vary with the job. It mainly depends on:

  • Specialist products, such as fire-rated or hygienic sealants
  • Joint width, depth and condition
  • Travel to remote or island sites
  • How accessible the joints are

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Before you send an enquiry

Good information means a firmer quote. When you get in touch, include:

  • What the building is and how it’s used
  • Access details, including height
  • Whether an asbestos survey exists
  • The postcode of the building

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.
