Need floor joint sealing in Ashton?

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

What we’re called out for in Ashton

Left open, joints fill with grit, wrap and wood fragments. Packed debris acts like a wedge every time a wheel crosses so the arrises break sooner.

These are often picked up first by site or facilities staff:

  • Chipped and spalling edges along forklift routes
  • Open saw cuts full of debris
  • Loading bay joints breaking down
  • Untidy open joints in a retail unit

Schools such as Bishops Waltham Infant School have movement joints in their walls and floors that are easy to overlook.

Before you book anyone

  • Proof of insurance
  • How they handle RAMS and site documents
  • The named product and why it was chosen
  • Health and safety accreditation such as CHAS

Questions to ask before you appoint anyone

Floor joint sealing in Ashton, done properly

We diagnose the floor first rather than guessing at a product: how wide the joints are, signs of ongoing movement, the wheel types crossing them and the state of the arrises. From that we choose between a semi-rigid filler and a more flexible sealant, area by area where it needs to be. Most enquiries involve a gap opening alongside old joint filler and saw-cut joints left open and packed with grit, on joints along racking aisles, loading bays and retail and showroom floors. Whoever orders the work in Ashton, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Halls, schools and small commercial buildings near places like Ashton have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Work for main contractors and building owners

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

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Ashton can sit alongside others in a wider programme across Hampshire.

From enquiry to sign-off

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes a day for smaller units, with bigger warehouse floors programmed over several visits, and our waste is bagged and taken away as we go. Rural sites near Ashton may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. First, the zones and order of work are agreed with you.
  2. Any joints with broken edges are flagged before work starts.
  3. Failed material and debris are removed and the joint cleaned.
  4. We fill the joints with the agreed product, finished level.
  5. You get a time for each zone to reopen.

Getting the site ready

  • Tell us which areas need to stay in use
  • Point out parking and an unloading spot
  • Confirm the product named in the specification

Getting a fixed 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 email drawings and photos.

What the job involves on each surface

Forklift and pallet-truck routes

Open route joints are hard on equipment and drivers. A filled joint lets wheels roll across and saves the edges.

Retail and showroom floors

Retail work is phased around trading. Give us your opening pattern and access windows and the phasing follows.

Questions we’re asked in Ashton

Can you take on a job at a hospital such as Moorgreen Hospital?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Is a smaller place like Ashton outside your area?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

When is resealing likely to be due?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Is it normal for joint filler to separate?

Young concrete carries on shrinking for a long time, so a semi-rigid filler can part from one face. It is usually dealt with by topping up.

Can you send site paperwork?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Who decides which product is used?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Leave it or put it right?

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. Halls, stores and units around places like Ashton may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

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

Looking after the joints

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Photograph any joint that starts to chip
  • Plan for a top-up on newer floors
  • Treat loading bay joints first if they’re failing
  • Check joint lines on busy aisles regularly

A routine walk of the busiest aisles shows how the joints are holding up. Look for separation down one side, new chips in the arris and debris gathering, and photograph anything that changes.

Regular inspection catches failing fills before the edges go. We can quote a programme that starts with the busiest areas so nothing is left to fail.
