Floor joint sealing for businesses in Kingston

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

Why it’s worth doing now in Kingston

An open joint is a modest filling job while its edges are sound. Left until they break, it needs an edge repair before any filling can start which means more downtime in that zone. Small buildings around Kingston suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Why appoint us

  • Fully insured, including public liability cover
  • A Constructionline member, so easy to vet
  • Failed material removed, not covered up
  • Over 20 years of commercial sealing

Floor joint sealing for commercial buildings in Kingston

Open joints take a beating from forklift and pallet-truck wheels. Each crossing knocks the unsupported edge until a crisp saw cut becomes a wide, broken groove. Filling the joint properly gives the edges back their support. It also smooths the route for drivers and stock. The enquiries we see most involve scruffy, dirty joint lines on a shop or showroom floor and brittle joint filler breaking up, on forklift and pallet-truck routes, retail and showroom floors and loading bays. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Kingston is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around places the size of Kingston, joints that need sealing tend to be in rural business units, farm buildings put to commercial use, schools and community buildings. Concrete floors and yards in these buildings move and crack like any others.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Doing it in-house

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

Owners, agents and contractors

We work for building owners and managing agents on everything from one building to a spread of sites around Kingston. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

Questions we’re asked in Kingston

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

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We check the specified product suits the exposure and pay close attention to preparation.

Will you take on work at estates like Copnor Bridge Business Centre, close to Kingston?

Yes. Our area takes in Kingston and its surroundings, with estates and business parks such as Copnor Bridge Business Centre included. Photos and a short description are enough for a first look.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

How long does a typical visit take?

We plan the time on site around your programme and access. You’ll have an expected duration with the quote.

Do you offer coloured sealant?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.

What guarantee do you give on joint filling?

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

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

What we can’t put right

We check first that sealant really is the fix. It isn’t the answer for:

  • Broken concrete either side of the joint
  • Wide or random cracking that suggests a structural issue
  • Damaged or worn floor coatings and screeds

Not sure which it is? You can ring 01277 525 020 or email us and we will tell you honestly.

Where we work in Kingston

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

How a job runs

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before we move to the next. For a site in Kingston, we plan so the whole job is done in one go where possible. Clear photos and measurements help us bring the right products.

  1. First, the zones and order of work are agreed with you.
  2. We point out joints whose edges need repairing first.
  3. Failed material and debris are removed and the joint cleaned.
  4. The chosen filler or sealant goes in flush with the slab.
  5. Each area is handed back when ready for traffic.

Getting the site ready

  • Let us know about inductions and permits
  • Arrange parking or a loading space
  • Point out any areas we must not close

Request a quote

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call the office on 01277 525 020 or send photos by email.

Where floor joints take the most wear near Kingston

Kingston sits close to the coast, within about 1 mile. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, so it pays to keep them sealed. At about 64 miles from central London, Kingston is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital, and their floor joints take forklift and pallet-truck traffic all day.

Business parks such as Copnor Bridge Business Centre (to the north of Kingston) have car parks, paved areas and long brick and panel elevations, all with movement joints. A campus such as University of Portsmouth (0.6 miles south of Kingston) has long runs of movement joint in its buildings, decks and paving. At places like The Bridge Shopping Centre, 0.6 miles to the south-west of Kingston, joints are sealed a section at a time so operations carry on.

Kingston is about 1 mile south-east of Portsmouth, in Portsmouth. Looking for floor joint sealing in Kingston? We can help, as we do across Portsmouth. Kingston is one of 19 places we cover in Portsmouth.

After the work

For the best life from the joints:

  • Stop forks and pallets being dragged across joints
  • Keep grit out of unfilled joints in the meantime
  • Mention any aggressive cleaning regime at quote stage
  • Plan for a top-up on newer floors

Ask drivers not to drag forks or pallets along the floor. Steel tines will mark a good joint over time if it keeps happening.

Edges tend to break slowly at first, then quickly. Once the first piece is out, wheels drop further and hit harder so early treatment saves a lot of trouble.
