Questions about Smeeth

Can you supply sealant in our brand colour for a site in Smeeth?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. The quote lists the colours the product is made in.

Is Smeeth too small for you to travel to?

No. Places such as Smeeth are covered as much as the big towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

What site paperwork can you provide?

We will confirm the paperwork you need, such as RAMS, an insurance certificate or CSCS details, with the quote. We hold CHAS accreditation and Constructionline membership and carry five million pounds of public liability insurance.

Are you CHAS accredited?

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

How soon can the area be used again?

We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Does the weather affect the work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.

How we handle commercial sealant contractors in Smeeth

Having a single contact for all your sites makes sealant far simpler to manage. Single jobs, multi-site packages and planned programmes all come to us, run the same way on every site: send details, get a fixed quote, we seal, and a 12-month guarantee once it’s signed off. To get a programme moving in Smeeth, ring 01277 525 020 or email the details over with the site addresses. We work on external facade joints, movement joints in walls and floors and kitchen worktops and splashbacks, and what we are called in for most is smeared sealant across finishes from a rushed job and gaps behind commercial kitchen worktops and sinks. Searching for sealant specialists in Smeeth? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

In Smeeth, as anywhere, the first joints to go are usually the ones that work hardest: south-facing perimeters, entrance thresholds and busy washrooms.

Work in smaller places such as Smeeth 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.

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.

What we can’t put right

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

  • Broken glass or blown double-glazed units
  • Leaks from pipework, wastes or valves (that’s plumbing)
  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)

Not sure which it is? You can ring 01277 525 020 or email the details over and we will tell you honestly.

What we seal

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

Diagnose, treat, sign off

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes anything from part of a day on a short run of joints to several weeks on a large phased package, and our waste is bagged and taken away as we go. Jobs in and around smaller places like Smeeth are usually planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. Site photos, drawings or a visit tell us what’s there and how it has failed.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. Sequence, access and working times are settled before the first joint is touched.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. We hand back each area with its cure time and our 12-month guarantee.

Getting the site ready

  • Have the specification and drawings to hand
  • Let us know about inductions and permits
  • Point out parking and an unloading spot

What Smeeth’s businesses ask us to seal

The South East is one of the drier parts of the UK. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it. Smeeth lies roughly 53 miles out from central London. This part of the South East is dense with business parks and out-of-town offices. Multi-site occupiers here often want one sealant contractor across all their buildings.

For tenants and agents on sites such as Evegate Business Park, which lies south-west of Smeeth, office fit-outs, reception joints and window perimeters are the usual sealant work. A business with units at Evegate Business Park and Mersham-le-Hatch Business Village needn’t use two contractors for its sealant. Shops and cafés around stations like Westenhanger station (3.6 miles south-east of Smeeth) trade from early, so work is timed around them.

Smeeth is about 5 miles east of Ashford, in Kent. Businesses, contractors and managing agents in Smeeth can call on us for sealant joints. We work across 931 places in Kent, from busy centres to rural villages. Brighton is covered too, some 52 miles away.

Commercial sites across TN25 are covered for sealant joints. We cover commercial and managed buildings on Church Road, Caroland Close and Woolpack Hill. Just outside Smeeth, we also work in Ridgeway (1 mile west), Brabourne Lees (1 mile north-east), Lilyvale (1 mile south-east), Bircholt Forstal (1 mile north-east) and Stone Hill (1 mile south-east). A short drive away, we cover Ashford (5 miles west), Canterbury (12 miles north-east), Dover (14 miles east), Folkestone (9 miles east), Faversham (14 miles north) and Hythe (6 miles south-east).

How the quote is worked out

Each job is priced on its own details. The main factors are:

  • The size and state of each joint
  • Whether old sealant has to be cut out first
  • Working within restricted access windows
  • Induction, permit and paperwork requirements

There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

Sending details for a quote

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

  • What the building is and how it’s used
  • A wide shot and a close-up of the area
  • How the joints are reached, and at what height
  • Approximate linear metres or a joint schedule

Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to call 01277 525 020 or send details through our quote form.

For managing agents and facilities managers

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, which keeps the paperwork simple.

How the job changes by surface

Shop fronts and retail fit-outs

Most shops can’t close for a reseal. We plan around the access windows the store gives us, phasing areas so the shop floor stays usable.

Commercial kitchens and tea points

Gaps and ragged beads trap dirt that cleaning can’t reach, which matters when environmental health officers look at a kitchen. Work is timed around the hours you give us so the kitchen isn’t out of use longer than needed.

Doing it in-house

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
