Facade sealing across Petham

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

What the job involves on each surface

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. These joints take full exposure to weather.

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.

Facade sealing in Petham, done properly

Sealant around windows, doors and cladding panels stops rain reaching the wall behind. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We remove failed sealant and install a new bead chosen for the joint and how far it moves. If you are dealing with gaps between rainscreen or cladding panels and unsightly perimeter sealant on a visible elevation, we can help, on perimeter joints where frames meet the structure, cladding panel joints and coping and flashing joints alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Petham, that means joint design, primers and backing rod as standard.

Conversions of older rural buildings near smaller places such as Petham 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.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Signs you need facade sealing in Petham

Overlaying old sealant is a common shortcut that fails quickly. Fresh silicone won’t stick to cured silicone.

Look out for the following:

  • Leaks at window and door perimeters
  • Weathered joints at frame-to-structure perimeters
  • Weathered facade joints that have lost their grip
  • Gaps between rainscreen or cladding panels

Recladding or extending a unit at a site like Stour Valley Business Park, 2.7 miles to the north of Petham, brings panel joints and frame perimeters into the programme.

What to look for in a quote

  • How the existing material will be dealt with
  • How joint depth will be controlled
  • How they handle RAMS and site documents
  • How long is the guarantee, and what does it include?

Choosing a commercial sealant contractor

What we can’t put right

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Render or concrete edges that have broken away
  • Replacing glass or failed glazing units

If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we’ll say what we think.

Where we work in Petham

  • Shopfront frames
  • Cladding panel joints

Questions about Petham

Is Petham too small for you to travel to?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Is a hospital such as Kent and Canterbury Hospital somewhere you can work?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

Will your applicators have CSCS cards?

Yes. If you need card details for site access, tell us and we will confirm them with the quote.

Can one quote cover more than one building?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.

Do you provide access for facade work?

We agree access with the client at the start. Tell us about access: existing scaffold, what you are arranging and any site restrictions, and we’ll price the work around it.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

General trades versus a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

On site: what to expect

Working in a building that stays open takes some planning. We sign and contain the area we’re in, keep walkways clear and work section by section so the rest of the building stays in use. Rural sites near Petham may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.
  3. Each joint is cut out and the edges inspected.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. We hand over with our 12-month workmanship guarantee.

What we need from you

  • Let building users know which areas are affected
  • Tell us your opening times and when work is allowed
  • Point out parking and an unloading spot

Facade sealing in Petham: the local picture

At about 53 miles from central London, Petham is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the 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 we time external mastic for dry faces and agree it with the site team.

When a school such as Petham Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. Building work at universities like University of the Creative Arts, 4 miles to the north-east of Petham, is often timed for the summer, mastic included.

Petham is about 4 miles south of Canterbury, in Kent. Businesses, contractors and managing agents in Petham can call on us for facade joints. We work across 931 places in Kent, large and small. There’s a separate page for London, about 53 miles away.
