Facade sealing for businesses in Charlton-in-Dover

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

After the work

Keep the joints in good shape with a few simple steps:

  • Walk the elevations once or twice a year
  • Avoid harsh cleaners on facade sealant
  • Report water ingress at frames as soon as it shows
  • Never let anyone seal over old sealant

Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration.

Get the joint design right when resealing: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.

Facade sealing in Charlton-in-Dover

Facade sealants sit in the sun, rain and frost every day, so they don’t last indefinitely. Life depends on movement, weathering, product choice and the quality of the original work. When the time comes, we cut the old sealant out completely and start again. If you have perimeter sealant that has split or peeled away and cold air coming in at window perimeters, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Charlton-in-Dover it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Building work in places the size of Charlton-in-Dover is normally small-scale: a handful of new houses, barn conversions, a school or hall extension. Even a small site needs its perimeter and facade joints sized, backed and sealed properly.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant.

Work for main contractors and building owners

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

Signs you need facade sealing in Charlton-in-Dover

Sometimes the substrate is the problem: crumbling render, spalling concrete or flaking paint take the sealant with them. When the joint edges need repair first, we say so.

Site and facilities staff are often the first to spot these:

  • Draughts around frames and panels
  • Unsightly perimeter sealant on a visible elevation
  • Hard, chalky sealant that no longer flexes
  • Water coming in around window frames

On a healthcare site such as Buckland Hospital, 0.7 miles west of Charlton-in-Dover, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

What your quote should include

  • How they’ll work around occupants
  • Health and safety accreditation such as CHAS
  • How long is the guarantee, and what does it include?
  • What site paperwork they can supply

Choosing a commercial sealant contractor

New build and refits around Charlton-in-Dover

The sea is no more than about 1 mile from Charlton-in-Dover. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so joint design, primers and product choice deserve extra care. Charlton-in-Dover 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, so external mastic is timed for workable conditions and agreed with the site manager.

For contractors refurbishing units at places like White Cliffs Business Park (1.3 miles north of Charlton-in-Dover), the mastic covers cladding panels, roller-door and window perimeters. When a college such as East Kent College, 0.5 miles south-east of Charlton-in-Dover, builds or refurbishes, the mastic package normally has to fit around students and staff.

Doing it in-house

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Putting right a botched joint often costs more than sealing it well at the start, 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.

From enquiry to sign-off

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and our waste is bagged and taken away as we go. For a site in Charlton-in-Dover, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.

  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. 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.

Before we start on site

  • Tell us what induction or permit system the site runs
  • Share your working hours and any access restrictions
  • Let building users know which areas are affected

FAQs: Charlton-in-Dover

Do you take on work at healthcare sites like Buckland Hospital?

Do you guarantee your work?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

How long does a job like this take?

That varies with the scale of the job, though a typical visit usually takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Do you take on multi-site work?

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.
