Facade sealing in Cheriton

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Why deal with it now?

If access is already up for other work, resealing at the same time makes sense. Combine it with planned external works and you only arrange access once, which is often the biggest saving. In a smaller place such as Cheriton, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Why us?

  • A fixed quote before work starts
  • Specification-led, product-correct work
  • CSCS-carded applicators
  • RAL and finish matching where the product range allows

Facade sealing in Cheriton, done properly

Facade joints are the line of defence between the weather and the building fabric. Once a perimeter seal fails, water tracks in around frames and panels. We remove failed sealant and install a new bead chosen for the joint and how far it moves. Most enquiries involve perimeter sealant that has split or peeled away and discoloured or dirty facade joints, across cladding panel joints, shopfront frames and stone and brick facade joints. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Cheriton is the same: the right product in a properly prepared joint.

On a small site around Cheriton, the mastic is best done in the fewest visits we can manage. Tell us when scaffold comes down and when decoration finishes, and we’ll plan around those stages.

Every job we finish is backed by a 12-month workmanship guarantee, in Cheriton as everywhere else we work. If our installation lets you down in that time, we return and fix it.

When to call us in Cheriton

When sealant lets go of a frame or panel, the cause is often the preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond, and movement soon pulls it away.

It’s worth sending us details if you spot any of the following:

  • Hard, chalky sealant that no longer flexes
  • Unsightly perimeter sealant on a visible elevation
  • Damp patches beside frames after rain
  • Patch repairs that keep failing

Hotel extensions and refits, at places such as The Royal Norfolk Hotel, 1 mile to the south of Cheriton, normally run between busy periods, so the sealing is squeezed into short windows.

  • Do they follow the manufacturer’s priming guidance?
  • Their approach to joint depth and backing

Contractors’ notes for Cheriton

Cheriton lies within about 1 mile of the sea. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, and the sealant, primer and backing need choosing with that in mind. A 2-mile radius around Cheriton takes in a good number of hotels. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.

For contractors at a college like Folkestone College, which lies east of Cheriton, perimeters and internal sealant are timed for the holidays. Recladding or extending a unit at a site like Golden Valley Shopping Centre (under half a mile south of Cheriton) brings panel joints and frame perimeters into the programme.

Cheriton is about 1 mile west of Folkestone, in Kent. Across the CT19 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Our Kent coverage takes in 931 places, large and small. For work in that direction, see our Brighton page (58 miles or so).

Commercial sites across CT19, CT20 and CT50 are covered. Buildings on Oaks Road, Firs Lane and Star Lane are within our area for facade joints. Access to Cheriton is via the M20 among other routes, so getting applicators and materials to site is simple.

Doing it in-house

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Honest limits

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:

  • Installing or repairing glazing systems
  • Damaged frames that need replacing
  • Leaks from roofs, gutters or failed flashings rather than sealant joints

If you’re not sure, just ring 01277 525 020 or email us and we will give you a straight answer.

Where we work in Cheriton

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

Questions about Cheriton

Do you take on work at healthcare sites like Royal Victoria Hospital?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is Golden Valley Shopping Centre, near Cheriton, within your area?

Yes. Estates, retail parks and business parks around Cheriton, Golden Valley Shopping Centre among them, are all within reach. Photos and a short description are enough for a first look.

Do you guarantee your work?

Yes. It runs for twelve months and covers how we prepared and sealed the joints, but not damage, misuse or other trades’ work.

Do you replace windows or glass?

No. That work needs a glazing specialist. What we seal are the joints around frames and panels on commercial buildings.

Is it okay to overlay old mastic?

No. A bead run over old sealant soon lifts. We remove the failed sealant, clean the faces, set the depth and reseal.

What about RAMS and site documents?

Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.

Can weather delay the job?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

How a job runs

We follow your site rules from the start: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. If neighbouring businesses or buildings around Cheriton need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.

  1. First we review photographs, 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.

What we need from you

  • Flag any permit to work we’ll need
  • Have the specification and drawings to hand
  • Explain the parking and delivery arrangements

Ask for a quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

After the work

A few simple habits keep the new joints working:

  • Confirm the survey covers external sealants in older buildings
  • Check that rainwater leaves the facade the way it was designed to
  • Investigate damp beside windows promptly
  • Share access with other external trades

Blocked sills and gutters push water at the joints. Sealant copes better when water runs off the facade as designed instead of soaking the joints.

Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos, and work stops until it’s tested if it’s suspected.
