About our expansion joint sealing in Horton Kirby

Our movement joint work takes in walls, panels, decks and floors: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. Every one calls for a sealant picked for its movement, exposure and traffic and we name it in the quote. If you have layers of sealant in a movement joint and damp inside where a wall movement joint has failed, we can put it right, on blockwork control joints, car park decks and ramps and cladding panel joints alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Horton Kirby, preparation and product choice get the time they need.

In and around smaller places like Horton Kirby, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Expansion joint sealing in Horton Kirby: the local picture

At about 16 miles from central London, Horton Kirby is within reach of the capital. The South East has large numbers of industrial estates and warehouses along the motorway corridors, and their floor joints take forklift and pallet-truck traffic all day. The 3 miles around Horton Kirby take in at least three named trading estates, business parks or retail parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.

On industrial estates such as Mills Trading Estate, 0.7 miles north of Horton Kirby, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic. In a school such as Horton Kirby Church of England Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. University campuses such as University of Greenwich (3.5 miles north of Horton Kirby) have car parks, paved walkways and building elevations with movement joints.

Horton Kirby is about 4 miles south of Dartford, in Kent. Businesses, contractors and managing agents in Horton Kirby use us for work on movement joints, as part of our coverage of Kent.

Why act early in Horton Kirby

Resealing is usually the answer, not replacing the element. Where the edges are sound, cutting out and resealing is enough. If the edges have broken up, we’ll tell you they need repairing first. Halls, stores and units around places like Horton Kirby may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Common questions from Horton Kirby clients

Is Horton Kirby too small for you to travel to?

No. Places such as Horton Kirby are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Can you work on a hospital site such as Darenth Park Hospital?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

Are expansion joints and movement joints the same thing?

Movement joint is the broad term for any joint built in to let a structure move. On site, people tend to use them interchangeably.

Do you seal on top of existing sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

How long will the joint resealing take?

Expect anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. We’ll confirm when each area can be used again.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

Owners, agents and contractors

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.

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Keeping the joints sound

After handover, these steps help:

  • Look over external and deck joints after a hard winter
  • Leave barriers in place until fresh joint sealant has cured
  • Record the sealant used and the date in the O&M file
  • Clear dirt from joint lines during routine cleaning

Floor joints on main traffic routes need watching more closely than the rest. Keep racking feet and heavy point loads off joint lines and flag chipped arrises before they spread.

Once debris packs a failed joint, the structure has nowhere to expand. The edges then take the pressure and start to spall and the reseal becomes an edge repair as well. Keeping the seal sound avoids all of that.

What we can’t put right

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:

  • Leaks coming from the membrane rather than the joint seal
  • Joints too narrow for the movement, which need redesigning by the engineer
  • Cracking or settlement that calls for an engineer’s assessment

Not sure which it is? You can call the office on 01277 525 020 or use the quote form and we’ll tell you honestly before you book.

Surfaces we seal

  • Podiums and floor movement joints
  • Brickwork movement joints
  • Car park decks and ramps
  • Cladding panel joints
  • Blockwork control joints
  • Precast concrete panel joints

From enquiry to sign-off

We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Smaller jobs around Horton Kirby can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. You get a fixed quote with the product and its movement capability stated.
  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. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Each joint is inspected and handed over with our 12-month guarantee.

What we need from you

  • Let us know about inductions and permits
  • Share the asbestos register for older buildings
  • Warn occupants and staff about the work

When to bring in a specialist

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
