Floor joint sealing for commercial buildings in Faversham

Before quoting, we look at what the floor is telling us: how wide the joints are, signs of ongoing movement, the wheel types crossing them and the state of the arrises. That tells us whether semi-rigid filler or flexible sealant suits each run and the answer can differ from one zone to the next. We work on construction joints, retail and showroom floors and joints along racking aisles, and the usual reasons a site gets in touch are grimy joint lines spoiling a showroom floor and brittle joint filler breaking up. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Faversham is the same: the right product in a properly prepared joint.

In a town the size of Faversham, floor joints are mostly in industrial and trade units, supermarkets and car parks. Smaller units can’t stop work for long, so we plan around the occupier’s hours.

Our workmanship is guaranteed for 12 months, in Faversham as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Diagnose, treat, sign off

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. Most work in Faversham is one building at a time: a school, a unit, an office or a block. We start with your photographs, drawings or a site visit, then send a fixed quote.

  1. A floor survey records every joint, its edges and what crosses it.
  2. The treatment and the zones are set out in a fixed quote.
  3. Old fill and packed debris come out until both faces are sound.
  4. Dust is vacuumed out and primer applied where specified.
  5. Filler or sealant is placed to depth and finished flush.
  6. We hand each phase back when it can take traffic.

Preparing the site

  • Confirm the product named in the specification
  • Flag any permit to work we’ll need
  • Point out any areas we must not close

Questions we’re asked in Faversham

Do you work in Faversham?

Yes. Faversham is in our area. Photos or drawings are enough for us to quote.

Will our site in Faversham have to close for joint sealing?

Rarely. Work is phased around your operations. The phasing plan comes with the quote.

How do you deal with asbestos in old sealant?

The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Is it fine to apply new sealant on top of old?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Why is there a gap next to the joint filler?

On newer slabs, the concrete keeps shrinking after the joints are filled and a stiff filler can separate down one side. A top-up normally puts it right.

When is resealing likely to be due?

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

Which sealant will you use?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Joints that move: notes for Faversham

Faversham is within about 3 miles of the coast. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, and edges left open tend to break up faster. Faversham is in the South East, one of the UK’s drier regions. External slab and deck joints still need a dry, clean joint to seal, while winter salting gets into any joint left open.

In and around Faversham, the right filler or sealant for each joint depends on the traffic and the movement it takes. Schools like Ethelbert Road Primary School often have long brick elevations with movement joints that age quietly.

Faversham is about 9 miles west of Canterbury, in Kent. We cover Faversham and the rest of Kent, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Faversham is one of 931 places in Kent on our list. London is covered too, some 44 miles away.

Why deal with it now?

Holding off until the whole floor can close can take a long time. Zone by zone, the worst aisles can be dealt with now and the remainder follows on a plan that suits you. A failed joint is easier to put right before damp shows inside. After a leak, there’s drying, repairs and redecoration on top.

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Why choose Mastic Doctor in Faversham

  • Products installed to the manufacturer’s instructions
  • CHAS accredited contractor
  • Old sealant cut out, never sealed over
  • Constructionline member for supplier checks

See our cost guide and our accreditations.

After the work

A few simple habits keep the new joints working:

  • Keep grit out of unfilled joints in the meantime
  • Hold traffic back until the product has cured
  • Allow for topping up joints as a new slab settles
  • Ask drivers not to drag forks or pallets

Normal floor cleaning is fine once the product has cured. Tell us about aggressive cleaning products or hot washing at quote stage so the product suits them.

Joints are easiest to look after when someone checks them regularly. A phased plan, worst routes first, spreads the work out and keeps on top of the rest.

Site staff or a sealant specialist?

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

For managing agents and facilities managers

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
