How we handle floor joint sealing in Peaks Hill

It isn’t only heavy industry. Retail units, showrooms and trade counters have slab joints crossed by trolleys, footfall and cleaning machines, where a gappy, dirty joint looks untidy and snags castors. A flush, well-finished joint tidies the whole floor. If you’re dealing with joint fill separating from the concrete and joint edges breaking up under truck wheels, we can put it right, on construction joints, retail and showroom floors and saw-cut induced joints alike. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Peaks Hill is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. In Peaks Hill, as everywhere in London, access, loading and the ULEZ all come into the plan.

Work we carry out in Greater London comes with a 12-month guarantee. If an installation problem shows up, phone 01277 525 020 or send details through our quote form and we will arrange a return visit.

Why deal with it now?

Broken joints shake trucks, stock and operators alike. Wheels and bearings wear faster and loads can shift, adding costs nobody plans for. A filled joint takes most of that out. In a London building, a failed joint rarely affects only one party. Putting it right early is less disruptive than dealing with the consequences.

We don’t publish prices, since every building and every scope is different. Call for a quote.

Owners, agents and contractors

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Peaks Hill can sit alongside others in a wider programme.

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first.

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.

Site maintenance staff can often handle a short internal joint. 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.

From enquiry to sign-off

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before we move to the next. For a job in Peaks Hill, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we’ll schedule to suit.

  1. First comes a walk of the floor to record joint sizes, broken edges and traffic routes.
  2. The quote fixes the price, names the filler or sealant and shows how the floor will be zoned.
  3. Old filler, debris and contamination are cut or routed out back to clean concrete.
  4. Dust is sucked out of the joint and a primer used if the product data sheet asks for one.
  5. The chosen product is placed to its specified depth and trimmed level with the floor.
  6. The area is handed back once it has cured enough to take traffic.

What we need from you

  • Clear stock, furniture or equipment away from the joints
  • For older buildings, check the asbestos register before work
  • Tell us what induction or permit system the site runs

When something else is needed

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Uneven floors that need grinding or levelling
  • Worn screed or surface finishes
  • Unstable slabs moving under traffic

If you’re not sure, just speak to us on 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

What we seal

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

How the quote is worked out

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Induction, permit and paperwork requirements
  • Phasing around occupants
  • Quantities, in metres or numbers
  • Access and working height

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

What to include in your enquiry

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • Asbestos survey details if the building is older
  • Whether the building will be occupied during the work
  • The site address and postcode
  • Any specification or named product

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Joints that move: notes for Peaks Hill

Peaks Hill has at least three named business or industrial parks inside a 3-mile radius. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. Few London car parks or loading bays can be taken out of use for more than a short spell, so we seal in sections and hand areas back as each cures.

For an occupier at a site such as Lysander Road Airport Industrial Estate, 1.1 miles north of Peaks Hill, the joints at loading doors and dock levellers typically see the hardest wear. At places like Silver Wing Industrial Estate, 1.1 miles north of Peaks Hill, joints are sealed a section at a time so operations carry on. Schools like Coloma Convent Girls' School often have long brick elevations with movement joints that age quietly.

Peaks Hill is about 1 mile north-west of Purley, in Greater London.

Your questions answered

Can you take on a job at a hospital such as Purley War Memorial Hospital?

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

Do you cover business parks and estates near Peaks Hill, such as Lysander Road Airport Industrial Estate?

Yes. Our area takes in Peaks Hill and its surroundings, with estates and business parks such as Lysander Road Airport Industrial Estate included. To start, just phone 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.

Is the floor joint work guaranteed?

There is a 12-month guarantee on our workmanship and the work is covered by public liability insurance.

How do we get a quote for floor joints?

Approximate metres of joint, photos of typical and worst areas, and a floor plan let us give a quick quote. For larger floors, a site visit is often best so give us a call on 01277 525 020 or email the details over to set one up.

Will you just go over the old sealant?

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

How do you choose the sealant?

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.

Can you fill joints where the arrises have spalled?

A filler needs sound edges to grip. We’ll tell you if the joint edges need repairing first and set out how that affects the job.
