Facade sealing near Flishinghurst

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

Diagnose, treat, sign off

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work normally takes anything from a single day to several weeks, depending on joint lengths, access and the weather. Jobs in and around smaller places like Flishinghurst are usually planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full and the joint faces cleaned.
  4. Primer is applied where the maker specifies it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. We go over the completed work with you before leaving.

Before we start on site

  • Tell us your opening times and when work is allowed
  • Confirm the product named in the specification
  • Clear stock, furniture or equipment away from the joints

Facade sealing for commercial buildings in Flishinghurst

Every facade quote starts with how the joints will be reached. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site. We work on stone and brick facade joints, window and door perimeters and cladding panel joints, and what we are called in for most is weathered joints at frame-to-structure perimeters and facade joints cracked through the middle. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Flishinghurst, that means joint design, primers and backing rod as standard.

In the countryside around places like Flishinghurst, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

A 12-month guarantee applies to all our work in Kent. If an installation problem shows up, give us a call on 01277 525 020 or use the quote form and we’ll arrange a return visit.

Different surfaces, different methods

Brick and stone facades

Stone can absorb plasticisers from the wrong sealant. We use a product suitable for the stone where the specification names one.

Render and coated surfaces

Where the joint will be painted over, a paintable hybrid or PU sealant may suit. The choice depends on the specification and finish.

Contractors’ notes for Flishinghurst

Flishinghurst is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager. Flishinghurst lies roughly 37 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.

For a contractor at a hotel such as Kennel Holt Country House Hotel, 0.7 miles to the east of Flishinghurst, the mastic often has to be finished before a reopening date. With historic properties like Scotney Castle (to the west of Flishinghurst) in the area, refurbishment work often meets old masonry that needs compatible sealants.

Flishinghurst is about 11 miles east of Royal Tunbridge Wells, in Kent. Any commercial site in Flishinghurst is covered, whether it’s a single job or part of a planned programme. 931 places across Kent fall within our area, Flishinghurst among them.

Looking after the joints

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

  • Note when each elevation was last resealed
  • Avoid harsh cleaners on facade sealant
  • Plan facade sealing alongside redecoration
  • Check the asbestos register before old mastic is disturbed

Look at perimeter and panel joints as part of routine building checks. Watch for splits, gaps at the edges, hardening and discolouration; record the locations.

Tie resealing in with redecoration, cladding repairs or other access. Sharing the access keeps the cost down and cuts time on site.

What sealant work can’t fix

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Damaged frames that need replacing
  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Providing access systems for the work

Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we will tell you honestly before you book.

Surfaces we seal

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

Signs you need facade sealing in Flishinghurst

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.

Most enquiries start with something like this:

  • Staining on stone next to old sealant
  • Perimeter sealant that has split or peeled away
  • Patch repairs that keep failing
  • Cladding panel joints that have opened up

Projects at schools like Colliers Green Church of England Primary School work to term dates, so mastic is programmed tightly.

Before you book anyone

  • Is the sealant right for the movement and the substrate?
  • What site paperwork they can supply
  • Whether their applicators hold CSCS cards
  • Do they follow the manufacturer’s priming guidance?

Questions about Flishinghurst

Can you take on a job at a hospital such as Benenden Hospital?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is a smaller place like Flishinghurst outside your area?

No. Places such as Flishinghurst are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Can you look at water coming in around a frame?

Yes. Photos are often enough to start, followed by a visit if needed. Failed perimeter sealant is a common cause, but not the only one, and we’ll tell you which.

Is it okay to overlay old mastic?

No. New sealant won’t hold on old sealant, so the old bead is cut away and the faces are cleaned before resealing. That is what makes the new joint last.

Which sealant do you use on facades?

The product follows the joint’s movement, the surfaces and the specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them and we follow the specified product.

Do you replace failed glazing units?

No. We don’t install glazing systems, windows or glass. We seal the joints around them, such as perimeter joints where frames meet the structure.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited and a Constructionline member.

What affects the price in Flishinghurst

We price every job individually. The main factors are:

  • Site requirements such as inductions and permits
  • How much existing material needs removing
  • Backing rod, priming and other preparation
  • Travel to remote or island sites

Pricing facade joints depends on quantities, condition and access, plus any specification you are working to. Call for a quote.

Sending details for a quote

For an accurate fixed quote, we need to understand the site. Send us:

  • Whether the building will be occupied during the work
  • Approximate linear metres or a joint schedule
  • Where the site is, with the postcode
  • How the joints are reached, and at what height

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to speak to us on 01277 525 020 or email drawings and photos with what you know.
