Floor joint sealing for businesses in Keycol

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Floor joint sealing in Keycol

Some joints reach us with their edges already broken. Filling against a crumbled arris won’t hold for long, so we’ll tell you if the joint edges need repairing first and leave that decision with you. Site teams most often ask us about sealant pulled out along a truck route and filler that has parted from one face, on loading bays, construction joints and retail and showroom floors. For commercial sealant work in Keycol, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Around smaller places such as Keycol, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

How the quote is worked out

Your fixed quote is built from the real scope. It allows for:

  • How accessible the joints are
  • Distance, for remote addresses
  • Site requirements such as inductions and permits
  • Quantities, in metres or numbers

The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Sending details for a quote

The more we know, the firmer the quote. Helpful details to send:

  • Approximate linear metres or a joint schedule
  • Whether an asbestos survey exists
  • Access details, including height
  • Any dates the work must fit around

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, give us a call on 01277 525 020 or email us.

General trades versus a specialist

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

On site: what to expect

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes between a day and a number of days, set by the joint lengths, the edge condition and the phasing you need, and our waste is bagged and taken away as we go. If others near Keycol need work, visits can be combined. You will have a fixed quote before work starts.

  1. Each area is assessed for joint width, arris damage and the wheels that cross it.
  2. A fixed quote follows, listing the treatment for each area and the order of work.
  3. Each joint is cleared of old fill and dirt and taken back to clean, sound edges.
  4. We vacuum each run and prime it if the chosen product requires a primer.
  5. Filler or sealant goes in to the right depth and is finished flush with the slab.
  6. Each phase reopens when the product is ready for wheels, then we start the next.

What we need from you

  • Tell staff and tenants when we’ll be in
  • Send asbestos survey details if the building is pre-2000
  • Send any specification or drawings in advance

What happens if it’s left?

Holding off until the whole floor can close can take a long time. Zone by zone, the worst aisles can be dealt with now while the rest of the floor carries on. For buildings around smaller places like Keycol, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Why appoint us

  • Fully insured, including public liability cover
  • Failed material removed, not covered up
  • Work to your specification and the manufacturer’s guidance
  • Workmanship guaranteed for 12 months

Common questions from Keycol clients

Is Keycol too far out for you?

Not at all. Keycol is within our area. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

Can being near the sea in Keycol affect the sealant we need?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We check the specified product suits the exposure and pay close attention to preparation.

Can you fill joints where the arrises have spalled?

We check the edges as part of the survey. Where they have broken away, we’ll tell you before quoting the filling, so nothing is filled that won’t hold.

Do you seal on top of existing 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.

How long does a typical visit take?

It depends on the scope, though a typical visit typically takes anything from a day for one loading bay to several days for a large floor, split into phases. Larger or phased jobs take longer, and we will give you a timescale with the quote.

How do you choose the sealant?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Is it normal for joint filler to separate?

Separation usually comes from slab shrinkage, poor preparation or the wrong product. We diagnose the cause before suggesting a fix.

What we can’t put right

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • A floor that rocks at the joints, which needs a structural fix
  • Level or flatness problems across the floor
  • Damaged or worn floor coatings and screeds

If in doubt, phone 01277 525 020 or use the quote form and we’ll say what we think.

Surfaces we seal

  • Joints along racking aisles
  • Saw-cut induced joints
  • Retail and showroom floors
  • Loading bays
  • Forklift and pallet-truck routes
  • Construction joints

Maintenance after handover

Keep the joints in good shape with a few simple steps:

  • Start with the dock areas, where joints fail soonest
  • Keep grit out of unfilled joints in the meantime
  • Ask drivers not to drag forks or pallets
  • Respect the cure time before traffic returns

Once cured, the joints get cleaned along with the slab. If you use strong chemicals or hot-water washing, mention it when we quote so the product suits them.

While the concrete edges are intact, it’s a filling job. Once they have broken away, edge repair comes first and that takes longer and closes areas for longer.

Floor joint sealing around Keycol: points for this area

With the shore within about 3 miles, Keycol counts as a coastal location. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, so a failed joint lets more in and the edges break up sooner. Keycol sits in one of the drier corners of the country, the South East. External slab and deck joints still need a dry, clean joint to seal, and where de-icing salt is spread in winter, open joints let it in.

Business parks such as Newington Enterprise Centre, 1 mile to the north-west of Keycol, have car parks, paved areas and long brick and panel elevations, all with movement joints. At places like Newington Industrial Estate (1.6 miles west of Keycol), joints are sealed a section at a time so operations carry on. Large sites such as Sittingbourne Memorial Hospital (2.2 miles south-east of Keycol) have car parks, service roads and long elevations with movement joints in brick and panels.

Keycol is about 2 miles west of Sittingbourne, in Kent. Anywhere in ME9, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Keycol is one of 931 places in Kent on our list for floor joints. There’s a separate page for London, about 35 miles away.

We cover the ME9 postcode districts for floor joints. Among the streets we cover are Rooks View, Hill Farm View and Rook Lane. Sites close to Keycol are covered too, including Bobbing (1 mile east), Chestnut Street (1 mile south), Newington (1 mile west), Danaway (1 mile south-west) and Oad Street (2 miles south). Bigger towns within reach include Maidstone (9 miles south-west), Gravesend (15 miles north-west), Whitstable (15 miles east), Faversham (9 miles east), Minster (7 miles north-east) and Kings Hill (13 miles south-west).
