Expansion joint sealing for Flackley Ash sites

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

How the quote is worked out

What shapes the price:

  • Backing rod, priming and other preparation
  • How much existing material needs removing
  • Whether the work must be split into stages
  • How much there is to seal

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Before you send an enquiry

A few photos plus some basic facts will normally do. It helps to include:

  • The postcode of the building
  • The product your specification calls for
  • How the joints are reached, and at what height
  • Asbestos survey details if the building is older

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.

Expansion joint sealing in Flackley Ash

We have been sealing expansion and movement joints for over 20 years for contractors, facilities managers and owners. Our applicators are CSCS-carded, we’re CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. Site teams most often ask us about arrises breaking up along floor joints and sealant pulling off the joint face, on brickwork movement joints, cladding panel joints and podiums and floor movement joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Flackley Ash it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around smaller places such as Flackley Ash, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Why deal with it now?

A torn seal left alone typically gets worse. Grit and water fill the gap and the material either side breaks up, so a reseal turns into an edge repair as well. Resealing early keeps the work to sealant. Halls, stores and units around places like Flackley Ash may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Why us?

  • CHAS accredited
  • Colours chosen to suit frames, cladding or finishes where possible
  • Commercial sealant work since 2005
  • Clear, fixed quotes

How a job runs

On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself normally taking a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. Smaller jobs around Flackley Ash can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. We look at the joints, their width and how they’ve failed.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Finished joints are checked and backed by our 12-month guarantee.

What we need from you

  • Explain the parking and delivery arrangements
  • Make sure the joints can be reached
  • Share the asbestos register for older buildings

Questions we are asked in Flackley Ash

Will our site in Flackley Ash have to close for joint sealing?

Rarely. Work is phased around your operations. Tell us which hours and entrances we can use and we’ll plan from there.

Is a smaller place like Flackley Ash outside your area?

No. Places such as Flackley Ash are covered as much as the big towns. We work across Greater London and the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

What if the joint edges are damaged?

Sound edges are essential. If they’re damaged, we will say so before any sealing, so the new seal has something to grip.

Can you work while the building is occupied?

Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.

Why do our movement joints keep failing?

Most often the movement is too much for the product or the joint width. That’s why we check width, depth and movement class before quoting so the same failure isn’t repeated.

What exactly is a movement joint?

Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Many people call it an expansion joint and both need a flexible seal.

Should maintenance staff do it?

Redoing a failed joint normally 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.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Where floor joints take the most wear near Flackley Ash

Flackley Ash is in the South East, one of the UK’s drier regions. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint. Central London is about 49 miles from Flackley Ash. The South East has large numbers of industrial estates and warehouses along the motorway corridors.

In and around Flackley Ash, the right filler or sealant for each joint depends on the traffic and the movement it takes. For a school such as Peasmarsh Church of England Primary School, playground and building joints can be done in the holidays.

What we can’t put right

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:

  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Changing the joint layout or spacing of a structure

If you are not sure, just speak to us on 01277 525 020 or email us and we’ll give you a straight answer.
