Facade sealing for Breach sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Should maintenance staff do it?

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

About our facade sealing in Breach

Water ingress at window frames is a frequent reason facilities managers contact us. Very often the perimeter bead has cracked or lost its grip. If the evidence points away from the sealant, we say so before quoting. The enquiries we see most involve cladding panel joints that have opened up and perimeter sealant that has split or peeled away, across cladding panel joints, stone and brick facade joints and coping and flashing joints. Most enquiries from Breach start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Sites around smaller places like Breach can be a fair drive from suppliers, so we come with everything the package needs. Send drawings or photographs and the programme and we’ll quote to suit.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Questions about Breach

Do you take on work at healthcare sites like Medway Maritime Hospital?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Will you take on work at estates like Newington Industrial Estate, close to Breach?

Yes. Estates, retail parks and business parks around Breach, Newington Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

How many days will you need on site?

It depends on the scope, but the work normally takes anything from a single day to several weeks, depending on joint lengths, access and the weather. For bigger or phased jobs, we will set out a timescale with the quote.

What site paperwork can you supply?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

Do you have public liability insurance?

Yes. We are fully insured, including public liability cover.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.

Which sealant do you use on facades?

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.

Do you need facade sealing in Breach?

When the sealant tears down its centre, it has normally been asked to move more than it can. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.

Clients normally get in touch after noticing something like this:

  • Gaps between rainscreen or cladding panels
  • Perimeter sealant that has split or peeled away
  • Discoloured or dirty facade joints
  • Perimeter joints where frames meet the structure

Recladding or extending a unit at a site like Newington Industrial Estate (0.6 miles south of Breach) brings panel joints and frame perimeters into the programme.

What your quote should include

  • Their public liability cover
  • Will failed sealant be removed rather than covered?
  • Is the sealant right for the movement and the substrate?
  • Do they follow the manufacturer’s priming guidance?

Our contractor checklist

Honest limits

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

  • Cracked or spalling substrates that need repair before sealing
  • Arranging specialist high-level access, which is planned with the client
  • Movement beyond what any sealant can handle

If you’re not sure, just call 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

How a job runs

At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. For a building around Breach, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. Failed sealant is cut out along its full length.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  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. We walk the finished joints with you before handing over.

Preparing the site

  • Tell staff and tenants when we’ll be in
  • Tell us which areas need to stay in use
  • Flag any permit to work we will need

Advice

Facade sealing in Breach: the local picture

Breach sits close to the coast, within about 3 miles. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, so we check the specified product suits the exposure before the first bead. Rainfall across the South East, Breach included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team.

When a school such as Newington Church of England Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. Hospital estates such as Medway Maritime Hospital (to the west of Breach) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Breach is about 3 miles east of Gillingham, in Kent. Our applicators travel to Breach for work on facade joints. Breach is one of 931 places in Kent on our list for facade joints. We also cover London, around 34 miles from Breach.

Different surfaces, different methods

Brick and stone facades

Stone can absorb plasticisers from the wrong sealant. The specified stone-compatible sealant is what we use.

Render and coated surfaces

Sealant can only hold as well as the render or paint beneath it. We remove flaking material so the bead bonds to a firm surface, and we’ll mention any edges that need repair.
