Floor joint sealing for businesses in Clayhall

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

Your questions answered

Can you work on a hospital site such as Gosport War Memorial Hospital?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is a smaller place like Clayhall outside your area?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can you phase floor joint work around operations?

In the majority of cases, just the area being treated is coned off. Each zone reopens when the product can take traffic and the next zone follows.

How long will the new sealant last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

What guarantee do you give on joint filling?

Every job has our 12-month guarantee. It covers our workmanship, not later slab movement or damage from impacts.

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. We can visit where that helps, and you can speak to us on 01277 525 020 or email the details over to arrange it.

Floor joint sealing in Clayhall

Open joints take a beating from forklift and pallet-truck wheels. Every pass chips at the bare concrete edge until a crisp saw cut becomes a wide, broken groove. A properly filled joint carries the wheel over and protects both arrises. It also smooths the route for drivers and stock. We work on retail and showroom floors, loading bays 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. A single leaking joint is often how a building in Clayhall first comes to us: we look at the rest while we’re there and tell you what we find.

In a smaller place such as Clayhall, floor and movement joints are often in agricultural and rural business units, schools and the odd small industrial yard. Their slabs and walls still need movement joints that work.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, call 01277 525 020 or send photos by email and we’ll come back to it.

Looking after the joints

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Start with the dock areas, where joints fail soonest
  • Keep trucks off new joints until we say they’re ready
  • Make joint checks part of your floor inspections
  • Plan for a top-up on newer floors

Keep traffic off fresh joints until the time we give you, and it’s worth enforcing. In a busy building, barriers keep early traffic away.

Treating joints while the arrises are sound keeps the work simple. After the edges go, repairs come into it and that takes longer and closes areas for longer.

For managing agents and facilities managers

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Clayhall can sit alongside others in a wider programme.

From enquiry to sign-off

Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. What matters most for a job in Clayhall is a clear list of what needs doing, so send photographs of each area. You will then get a fixed price for the work.

  1. We walk the floor and mark up joint widths, edge damage and traffic routes.
  2. The treatment and the zones are set out in a fixed quote.
  3. Each joint is cut or routed back to clean, sound concrete.
  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.

Getting the site ready

  • Send any specification or drawings in advance
  • Flag any permit to work we will need
  • Share your working hours and any access restrictions

Advice

Floor joint sealing in Clayhall: the local picture

Clayhall sits close to the coast, within about 1 mile. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, so a failed joint lets more in and the edges break up sooner. At about 67 miles from central London, Clayhall is within reach of the capital. The roads out of London are lined with trade parks and distribution sheds.

Another example is Cranbourne Industrial Estate, 0.6 miles north of Clayhall, where floors and yards would be done in stages around the occupiers. Centres like Tricorn Centre (2.3 miles north-east of Clayhall) have mall floors and service decks whose joints carry steady traffic.

Clayhall is about 2 miles south-east of Gosport, in Hampshire. Across the PO12 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. 723 places across Hampshire fall within our area, including Clayhall.

Doing it in-house

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

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

Signs you need floor joint sealing in Clayhall

An ageing filler or sealant can go brittle and split especially under daily scrubbing and traffic. At that point it neither holds the edges nor keeps debris out.

Any of the following is a good reason to get the joints checked over:

  • Failing joints at loading bays and dock doors
  • Cracked and crumbling joint fill
  • Flexible sealant torn out by wheels
  • Grimy joint lines spoiling a showroom floor

University campuses such as University of Portsmouth - North Zone (1.8 miles north-east of Clayhall) have car parks, paved walkways and building elevations with movement joints.

What your quote should include

  • How the existing material will be dealt with
  • Which product they’ll use, and why it suits the joint
  • What site paperwork they can supply
  • How they’ll work around occupants

How to choose a sealant contractor

Cost factors for floor joints

To price the job, we consider:

  • Which sealant the job calls for
  • Working within restricted access windows
  • How much existing material needs removing
  • Joint width, depth and condition

What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote once you have the details.

Sending details for a quote

However big the job, these details speed things up:

  • Specification clauses that apply
  • Your programme or deadline
  • The site address and postcode
  • Whether an asbestos survey exists

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.
