Commercial mastic work in Biddenden

Most of the buildings we seal stay open while we are there. Tell us your site hours and access windows and we will plan around them; phased work can also be planned so areas stay in use. It’s the same approach in offices, retail units, hotels, schools and healthcare buildings. Most enquiries involve untidy joints in a reception, shop floor or lobby and shrunken sealant along kitchen worktops and splashbacks, on kitchen worktops and splashbacks, floor and threshold joints and movement joints in walls and floors. Facilities teams, main contractors and managing agents in Biddenden tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

A lot of what we do in Biddenden is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

Work in smaller places such as Biddenden tends to come one building at a time: a pub kitchen, a hall, a small office. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

A 12-month guarantee applies to all our work in Kent. If an installation problem shows up, call the office on 01277 525 020 or email the details over and we will arrange a return visit.

What happens if it’s left?

Some low prices are low because nothing gets cut out. New sealant laid on old silicone has nothing to bond to, so it peels. Our prices always include removal of the failed bead and full joint preparation, which is where the lasting value is. Converted and older buildings near places like Biddenden tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

Pricing sealant joints depends on how many there are, their condition and the access. Ask us for a fixed quote.

Commercial sealant contractors around Biddenden: what changes locally

Biddenden is in the South East, one of the UK’s drier regions. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it. At about 41 miles from central London, Biddenden is within reach of the capital. The commuter belt holds a great many offices, retail parks and business parks. Firms with branches across the South East can use one contractor for every site.

If you run an office at a site such as Business Park, which lies south of Biddenden, the sealant at reception desks, tea points and frames ages with each fit-out. Shops and cafés around stations like Headcorn station (3.5 miles north of Biddenden) trade from early, so work is timed around them.

Biddenden is about 10 miles west of Ashford, in Kent. We cover commercial sites throughout Biddenden, whether it’s a single job or part of a planned programme. We work across 931 places in Kent, large and small. There’s a separate page for Brighton, roughly 39 miles from Biddenden.

We cover the TN27 postcode districts. If your site is on High Street, The Meadows and Cloth Hall Gardens or close by, send details and we will quote for sealant joints.

What sealant work can’t fix

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Roof leaks that only look like a joint problem
  • Broken glass or blown double-glazed units
  • A dripping trap, valve or pipe behind a fitting

If you are not sure, just give us a call on 01277 525 020 or email a schedule or drawings and we will give you a straight answer.

Surfaces we seal

  • Washrooms and tea points
  • Window and door perimeters
  • External facade joints
  • Kitchen worktops and splashbacks
  • Floor and threshold joints
  • Movement joints in walls and floors

General trades versus a specialist

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.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

FAQs: Biddenden

Can you match sealant colours for premises in Biddenden?

Yes, we can typically get close to most finishes from the product’s colour range. Available colours for the product are confirmed with the quote.

Is Biddenden too small for you to travel to?

Not at all. Biddenden is within our area. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Do you hold CHAS accreditation?

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

Does commercial sealant work come with a guarantee?

A 12-month guarantee covers the workmanship. Keeping joints clean and inspected helps them last well beyond that.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

What sets the cost

A fixed quote reflects the actual work. It allows for:

  • The product specified
  • Distance, for remote addresses
  • The size and state of each joint
  • How much existing material needs removing

What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote once you have the details.

What to include in your enquiry

Good information means a firmer quote. When you get in touch, include:

  • Whether the building will be occupied during the work
  • Where the site is, with the postcode
  • Photos of the joints, close up and from further back
  • The product your specification calls for

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.

After the work

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Keep abrasive pads and scrapers off resealed joints
  • Check joints after other trades have worked nearby
  • Log reseals in the O&M or maintenance records
  • Keep washroom and kitchen extraction working

Give fresh sealant time to cure before it’s cleaned, wetted or walked past. Cure time varies with the product, conditions and depth of the joint, and we confirm it when each area is handed back. Leaving the area closed until then keeps the bead neat.

Movement joints that fill with debris stop working. With nothing soft to close against, the materials either side take the load and start to break up. That turns a sealant job into something bigger.

Our process

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, with the work itself usually taking anything from part of a day on a short run of joints to several weeks on a large phased package. Rural sites near Biddenden may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. First, details reach us through the quote form or a site visit.
  2. The cause is diagnosed and the scope priced as a fixed quote.
  3. Work is phased around your occupiers where areas need to stay in use.
  4. Every failed bead is removed rather than covered.
  5. Each joint gets a suitable sealant, laid to depth and tooled.
  6. We check the work with you, and the 12-month guarantee starts.

Preparing the site

  • For older buildings, check the asbestos register before work
  • Let us know about inductions and permits
  • Clear stock, furniture or equipment away from the joints
