About our facade sealing in Bethersden

We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure for clients around Bethersden. Where sealant is the specified fix, we also take on coping and flashing joints. The enquiries we see most involve perimeter joints where frames meet the structure and perimeter sealant that has split or peeled away, on cladding panel joints, stone and brick facade joints and coping and flashing joints. Facilities teams, main contractors and managing agents in Bethersden tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Around smaller places like Bethersden, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant.

What the job involves on each surface

Render and coated surfaces

Paintable sealants exist for joints that will be coated. We confirm the product with you before starting.

Precast concrete panels

Joints between precast panels carry real movement. A sealant of the right movement class goes in over backing rod with primer where the product requires it.

Facade sealing in Bethersden: the local picture

Bethersden is about 45 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand. The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager.

For contractors at a school such as Bethersden Primary School, sealing has to be finished before term starts. Older buildings in the area around Bethersden, such as Godinton House (4 miles north-east of Bethersden), need care when sealed: the product has to suit soft or historic materials.

Bethersden is about 5 miles west of Ashford, in Kent. We cover Bethersden, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Bethersden is one of 931 places we cover in Kent for facade joints. Sites around Brighton have their own page, about 44 miles away.

We take on facade joints across the TN26 postcode area. For a building on The Dene, Forge Hill and Forgefield or nearby, we can quote for facade joints. We also cover Wissenden (1 mile north-west), Further Quarter (2 miles west), Chambers' Green (2 miles north), Maltman's Hill (2 miles north-west) and High Halden (3 miles south-west). Nearby towns on our patch include Maidstone (14 miles north-west), Ashford (5 miles east), Sittingbourne (15 miles north), Faversham (14 miles north-east), Hythe (15 miles east) and Davington (14 miles north-east).

Questions we are asked in Bethersden

Can the mastic package for our job in Bethersden follow the site programme?

Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Is Bethersden too far out for you?

No. Small places get the same service as large ones. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

Can you find out why a window is leaking?

Yes. We look at the perimeter sealant and tell you whether it has failed as part of pricing. If the water seems to come from a roof, sill or the glazing unit instead, we say so.

Can staff carry on working while you are here?

In the majority of cases, yes. We phase the work so most of the building stays in use.

Which sealant do you use on facades?

The product follows the joint’s movement, the surfaces and the specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

When to bring in a specialist

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Aftercare for building managers

Problems stay small when the joints are checked regularly. Specifically:

  • Share access with other external trades
  • Avoid harsh cleaners on facade sealant
  • Avoid patch repairs on failed facade joints
  • Note when each elevation was last resealed

Let the new sealant cure before washing the facade or windows near it. Pressure washers and harsh cleaners can damage a fresh bead and tell your cleaning contractor.

Building facade joints into a maintenance cycle avoids emergency repairs. Regular checks let you renew joints before water gets in, rather than waiting for a ceiling stain.

How the quote is worked out

The price varies from site to site. Expect it to depend on:

  • Induction, permit and paperwork requirements
  • Backing rod, priming and other preparation
  • How much existing material needs removing
  • Phasing around occupants

Pricing facade joints depends on how many there are, their condition and the access, plus any specification you are working to. Call for a quote.

Before you send an enquiry

The more we know, the firmer the quote. Helpful details to send:

  • Any specification or named product
  • Whether the building will be occupied during the work
  • The asbestos register, for older buildings
  • A wide shot and a close-up of the area

Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. To get it moving, call 01277 525 020 or email a schedule or drawings.

What sealant work can’t fix

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • 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 you are not sure, just call 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

Joints and surfaces we work on

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

Our process

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work usually takes anything from a single day to several weeks, depending on joint lengths, access and the weather. Rural sites near Bethersden may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. We plan access and the order of elevations with the client.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. We remove the old bead and check the edges are sound.
  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.

Before we start on site

  • Flag any permit to work we’ll need
  • Point out parking and an unloading spot
  • Tell us which areas need to stay in use

Getting a fixed quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
