Floor joint sealing in Keston

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

When to bring in a specialist

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

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. That’s why many clients bring in a specialist from the beginning.

Floor joint sealing for commercial buildings in Keston

Forklifts and pallet trucks are hard on open joints. Each crossing knocks the unsupported edge, and over time a neat cut turns into a ragged channel. Filling the joint properly gives the edges back their support. It also smooths the route for drivers and stock. We work on retail and showroom floors, construction joints and saw-cut induced joints, and the failures we are asked to look at most are joint fill separating from the concrete and chipped and spalling edges along forklift routes. Searching for sealant specialists in Keston? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

Most London buildings can’t shut a car park, loading bay or warehouse floor for long. Joints are done in sections, with bays coned off one after another, so the site keeps operating, at times agreed with the building manager.

A 12-month guarantee applies to all our work in Greater London. If an installation problem shows up, call 01277 525 020 or send details through our quote form and we’ll arrange a return visit.

Our process

At the end of each section, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. For a job in Keston, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.

  1. We walk the floor and mark up joint widths, edge damage and traffic routes.
  2. You receive a fixed quote showing products and phasing.
  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. Zones reopen once cured and the work moves on.

What we need from you

  • Let building users know which areas are affected
  • Flag any permit to work we will need
  • Point out any areas we must not close

Advice

FAQs: Keston

Can you work at a site such as Glebe Farm Business Park, by Keston?

Yes. Estates, retail parks and business parks around Keston, Glebe Farm Business Park among them, are all within reach. A few photographs and the unit address let us price the work.

Can you cope with the access rules in a London building?

Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. We allow for the ULEZ, which covers every borough

How many days will you need on site?

That varies with the scale of the job, but the work usually takes a day for smaller units, with bigger warehouse floors programmed over several visits. For bigger or phased jobs, we will set out a timescale with the quote.

What guarantee do you give on joint filling?

There is a 12-month guarantee on our workmanship, and we hold public liability insurance.

Is colour matching possible?

That depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.

How soon can traffic go back on the floor?

The wait is set by the product’s cure time and cooler floors take longer. Phasing is planned with that in mind.

Do you use semi-rigid filler or flexible sealant on floor joints?

It depends on the traffic and the movement. Forklift routes generally call for a semi-rigid filler that holds the arrises and joints with more movement take a flexible sealant.

Traffic, movement and joints around Keston

Basement car parks and service yards in London tend to be in use all working day, so we seal in sections and hand areas back as each cures. The 3 miles around Keston take in at least three named trading estates, business parks or retail parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.

Keston is inside London’s ULEZ, as is the rest of Greater London; tell us about loading bays, goods lifts and parking when you send details. Phasing is what makes joint work possible on busy sites such as Vulcan Way Industrial Estate (1.9 miles south-west of Keston): one bay, aisle or car park row at a time. Office parks like Glebe Farm Business Park, 0.8 miles to the south of Keston, have decks, ramps and clad elevations whose joints take movement every day.

When something else is needed

Honesty saves time and money. Fresh joints won’t solve:

  • A floor that rocks at the joints, which needs a structural fix
  • Level or flatness problems across the floor
  • A failing floor coating, which is a flooring contractor’s job

If in doubt, call 01277 525 020 or send details through our quote form and we’ll say what we think before you book.

Owners, agents and contractors

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

What sets the cost

Each job is priced on its own details. The things that drive the figure:

  • Location, for remote and island sites
  • Any access equipment needed
  • Phasing around occupants
  • Whether old sealant has to be cut out first

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

What we need to price the job

There’s no need for a formal survey. A few details are enough to get going:

  • Approximate linear metres or a joint schedule
  • The asbestos register, for older buildings
  • Access details, including height
  • A wide shot and a close-up of the area

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call 01277 525 020 or email a schedule or drawings with what you know.

Why deal with it now?

Broken joints shake trucks, stock and operators alike. Wheels and bearings wear faster and loads can shift, which nobody budgets for. A properly filled joint smooths the route. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.

What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote once you have the details.
