About our facade sealing in Capel-le-Ferne

A good facade joint depends on design as much as product. Joint width needs to match how far the joint moves and how far the sealant can stretch, while rod fixes the depth and stops the bead sticking to the rear, often at around 2:1 width to depth, as the manufacturer advises. The enquiries we see most involve facade joints cracked through the middle and draughts around frames and panels, on coping and flashing joints, cladding panel joints and perimeter joints where frames meet the structure. A specialist sealant contractor works differently from a general builder: in Capel-le-Ferne, that means joint design, primers and backing rod as standard.

Around smaller places like Capel-le-Ferne, building work typically 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.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Questions about Capel-le-Ferne

Our building in Capel-le-Ferne is near the coast: does that change the sealant?

It can. Coastal exposure works external joints harder than inland weather. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Is hospital work, at somewhere like Royal Victoria Hospital, something you do?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Does weather matter for sealant work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Do you run new sealant over the existing bead?

No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely. That is what makes the new joint last.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

Do you use silicone for external joints?

Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Some joints call for hybrid, PU or polysulphide instead, as the specification or substrate requires.

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

New build and refits around Capel-le-Ferne

Capel-le-Ferne sits close to the coast, within about 1 mile. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, so joint design, primers and product choice deserve extra care. Rainfall across the South East, Capel-le-Ferne included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.

New units and refits on sites such as Highfield Industrial Estate (to the south-west of Capel-le-Ferne) need their panel and perimeter joints sealed to the specification. On a campus such as University Centre Folkestone, 2 miles south-west of Capel-le-Ferne, new teaching buildings and residences are usually built and refurbished around the academic year. When a college such as Folkestone College (2.5 miles south-west of Capel-le-Ferne) builds or refurbishes, the mastic package normally has to fit around students and staff.

Keeping the joints sound

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Investigate damp beside windows promptly
  • Inspect facade joints on a regular cycle
  • Keep pressure washers away from fresh sealant
  • Insist on a full cut-out when joints are renewed

Anything drilled through a facade joint breaks the seal. Ask the installer to reseal it properly with a compatible product.

Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail.

What affects the price in Capel-le-Ferne

A fixed quote reflects the actual work. It takes account of:

  • Site requirements such as inductions and permits
  • Distance, for remote addresses
  • Specialist products, such as fire-rated or hygienic sealants
  • Working within restricted access windows

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

What we need to price the job

A good diagnosis starts with the right details. Tell us:

  • The postcode of the building
  • How the joints are reached, and at what height
  • Photos of the joints, close up and from further back
  • Your programme or deadline

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

When it isn’t the sealant

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

  • Render or concrete edges that have broken away
  • Replacing glass or failed glazing units
  • Joints whose design needs changing by the specifier

If in doubt, call the office on 01277 525 020 or send photos by email and we will say what we think.

Where we work in Capel-le-Ferne

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

Should maintenance staff do it?

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Commercial clients in Capel-le-Ferne

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

We work for building owners and managing agents on everything from one building to a spread of sites around Capel-le-Ferne. Several sites can go on one quote, so there’s one set of paperwork to deal with.
