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

Commercial mastic work in Kempe's Corner

We have applied sealant on commercial sites for over 20 years, and the paperwork side is in order: we’re CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. Let us know which site documents you need and they’ll be confirmed with the quote. We work on washrooms and tea points, kitchen worktops and splashbacks and external facade joints, and the failures we are asked to look at most are weathered facade sealant that no longer flexes and sanitary sealant that has gone black and patchy. For commercial sealant work in Kempe's Corner, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Multi-site clients with buildings in and around Kempe's Corner can put several sites on one programme, so standards and paperwork match across every site.

Commercial sealant work around smaller places like Kempe's Corner tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Each has kitchens, washrooms and frames whose joints need renewing in time.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Our process

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes as long as the agreed scope needs, from a single visit to a programme spread over several weeks, and we clear our waste as we work. Smaller jobs around Kempe's Corner can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.

  1. First, details come to us: photographs, drawings or a schedule of the areas.
  2. Next comes a diagnosis and a fixed quote.
  3. Before anything is cut out, we agree access, timings and sequence.
  4. We strip the failed bead and prepare both faces of the joint.
  5. The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
  6. Each area is inspected, signed off and backed by our 12-month guarantee.

Preparing the site

  • Have the specification and drawings to hand
  • For older buildings, check the asbestos register before work
  • Tell staff and tenants when we will be in

Keeping the joints sound

Regular inspection catches problems early. In particular:

  • Ask fit-out and M&E contractors to report any sealant they disturb
  • Keep abrasive pads and scrapers off resealed joints
  • Keep washroom and kitchen extraction working
  • Report cracked or peeling sealant early

New joints need their full cure time before they take water, cleaning or traffic. Cure time varies with the product, conditions and depth of the joint. Leaving the area closed until then keeps the bead neat.

Once sealant fails in a movement joint, grit and debris get in. The joint can no longer close, so its edges crack or spall. At that point it’s a repair job rather than a reseal.

Working on commercial sites near Kempe's Corner

The 3 miles around Kempe's Corner take in at least three named trading estates, business parks or retail parks. Each new occupier on a park like these tends to refit, from reception to staff kitchen, often in a colour the occupier specifies. Kempe's Corner sits in one of the drier corners of the country, the South East. Drier doesn’t mean dry every day, so frontage work still has some give in the dates.

For a hotel such as Eastwell Manor Hotel (1.3 miles north-west of Kempe's Corner), the colour of a joint at the bar or the bath matters to the look of the room. For premises near Wye station (0.8 miles east of Kempe's Corner), footfall is part of the plan: work is phased so shops and offices keep trading. A business with units at Eurogate Business Park and Henwood Industrial Estate needn’t use two contractors for its sealant.

Cost factors for sealant joints

These are the things that shape the price:

  • Whether old sealant has to be cut out first
  • Whether the work must be split into stages
  • Specialist products, such as fire-rated or hygienic sealants
  • Any access equipment needed

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.

What to include in your enquiry

Whether it’s one area or a whole building, these details speed things up:

  • What the building is and how it’s used
  • Drawings or a marked-up plan, if available
  • Where the site is, with the postcode
  • Access details, including height

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. To get it moving, phone 01277 525 020 or email drawings and photos.

General trades versus a specialist

Paperwork matters too. 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.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Your questions answered

Is Kempe's Corner too far out for you?

No. Places such as Kempe's Corner are covered as much as the big towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Does a hotel in Kempe's Corner need to shut while its sealant is renewed?

In the majority of cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.

Will the building have to shut during the work?

That comes down to planning: we agree access windows, phase the work and keep enough facilities open. Tell us what has to stay open and we will plan the job around it.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.

Does the weather affect the work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Which site documents can you send us?

Let us know your requirements when you ask for a price, and we will confirm the RAMS, insurance and CSCS details with the quote. From you, we’ll need the asbestos information for older buildings and any site rules.

Do you check for asbestos before removing sealant?

In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before disturbing old sealant, and if something is suspected, work stops until it’s tested.

Why deal with it now?

Leaving a failed joint rarely saves money. Once water gets behind the seal, finishes and ceilings underneath are next, which brings decorators and flooring contractors into the repair. Resealing while only the sealant has failed keeps the job small. For buildings around smaller places like Kempe's Corner, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

What the job involves on each surface

Facade and cladding joints

On a facade, a failed joint is often only visible close up. Close-up photos or a site visit tell us what’s needed, and we will confirm the colours available for the specified product.

Movement joints in walls and floors

Floor joints that take trolleys or forklifts need a tougher filler or sealant. The choice comes down to how much the joint moves and what runs over it; if the arrises are broken, we will say so before sealing.
