FAQs: Frant

Can you work around term dates at a campus such as Canterbury Christ Church University - Salomons?

Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is Royal Victoria Shopping Centre, near Frant, within your area?

Yes, sites like Royal Victoria Shopping Centre are within our area, along with the rest of Frant. A few photos and the unit address let us price the work.

What will the job cost?

That depends on the job: quantities, access, the product and any phasing. Call for a quote and we’ll price it properly.

Do you install glazing systems?

No. A glazing contractor handles that. What we seal are the joints around frames and panels across the facade.

Do you seal facades in winter?

Rain and frost can pause external sealing. The programme allows for it and we tell you if the forecast changes things.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

Are you CHAS accredited?

Yes. We are CHAS accredited and a Constructionline member.

How we handle facade sealing in Frant

External joints face UV, rain, temperature swings and building movement all year, so they don’t last indefinitely. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When it fails, the whole bead is cut away and the joint rebuilt. The enquiries we see most involve sealant pulling away from frames or panels and patch repairs that keep failing, on perimeter joints where frames meet the structure, stone and brick facade joints and window and door perimeters. For commercial sealant work in Frant, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

In the countryside around places like Frant, 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.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Quoting for work in Frant

These are the things that shape the price:

  • The total length or number of joints
  • How accessible the joints are
  • Travel to remote or island sites
  • Specialist products, such as fire-rated or hygienic sealants

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Sending details for a quote

To price the job accurately, we need to understand the site. Send us:

  • The site address and postcode
  • Any specification or named product
  • Access details, including height
  • Your programme or deadline

The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or call the office on 01277 525 020 or send photos by email to discuss it first.

Commercial clients in Frant

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Surface by surface

Precast concrete panels

Precast panel joints have to absorb thermal and structural movement. A sealant of the right movement class goes in over backing rod, primed where the maker specifies.

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. We remove flaking material so the bead bonds to a firm surface, and areas needing repair are flagged.

Why act early in Frant

Each spell of rain drives water past a failed facade joint. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing early costs far less than repairing what the water reaches. Halls, stores and units around places like Frant may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

Contractors’ notes for Frant

The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack. Frant lies roughly 32 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme.

Hotel extensions and refits, at places such as The Abergavenny Arms Hotel (under half a mile north-west of Frant), usually run between busy periods, so the sealing is squeezed into short windows. New units and refits on sites such as Royal Victoria Shopping Centre, 2.7 miles to the north of Frant, need their panel and perimeter joints sealed to the specification.

Frant is about 3 miles south of Royal Tunbridge Wells, in East Sussex. We cover commercial sites throughout Frant, for single jobs and planned programmes alike. Frant is one of 308 places we cover in East Sussex for facade joints. We also cover Brighton, some 25 miles away.

When to call us in Frant

Adhesive failure, where the sealant peels away from one face, typically comes from poor preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond, and movement soon pulls it away.

Things that typically lead to an enquiry:

  • Water coming in around window frames
  • Weathered facade joints that have lost their grip
  • Failed seals around shopfront and entrance frames
  • Cladding panel joints that have opened up

For contractors at a school such as Frant Church of England Primary School, sealing has to be finished before term starts.
