Expansion joint sealing for commercial buildings in Kingham

We’ve been sealing expansion and movement joints for over 20 years. Our applicators are CSCS-carded, we are CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. Site teams most often ask us about chipped joint edges on forklift routes and water getting into the wall through a failed joint, on precast concrete panel joints, podiums and floor movement joints and car park decks and ramps. Whether you call it commercial sealant work, mastic application or joint sealing, in Kingham it comes down to the same thing: the right product in a properly prepared joint.

Smaller community and commercial buildings around Kingham have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.

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

Building owners, agents and FMs in Kingham

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Kingham. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Common questions from Kingham clients

Is Kingham too far out for you?

No. Places such as Kingham are covered as much as the big towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Is hospital work, at somewhere like Moore Cottage Hospital, something you do?

Yes, provided the work is planned with the site’s estates team. 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. 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.

Do you take on small jobs?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

Are you insured?

Yes. We’re fully insured, and the certificate can go with your quote.

Can you work to our specification?

Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.

Can you quote from photographs?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.

Floors, slabs and movement joints in Kingham

Kingham is in the South East, one of the UK’s drier regions. Even so, yard and car park joints are only sealed when they’re dry and clean, and where de-icing salt is spread in winter, open joints let it in.

Hospitals like Moore Cottage Hospital (to the west of Kingham) have multi-storey or surface car parks whose joints carry vehicles round the clock.

Kingham is about 10 miles north of Carterton, in Oxfordshire. Anywhere in OX7, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Kingham is one of 423 places we cover in Oxfordshire for movement joints. There’s a separate page for Oxford, about 20 miles away.

Commercial sites across OX7 are covered for movement joints. We cover commercial and managed buildings on Station Road, Cozens Lane and Orchard Way. Access to Kingham is via the B4450 among other routes. If your building is just outside Kingham, we cover Bledington (1 mile south-west). Bigger towns within reach include Witney (10 miles south-east), Carterton (10 miles south), Chipping Norton (4 miles north-east), Neithrop (15 miles north-east), Ruscote (15 miles north-east) and Woodstock (13 miles east).

Aftercare for building managers

Keep the joints in good shape with a few simple steps:

  • Look over external and deck joints after a hard winter
  • Raise snow-clearing blades over deck joints where possible
  • Avoid parking heavy plant or pallets on joint lines
  • Record the sealant used and the date in the O&M file

In warehouses, forklift and pallet-truck routes take the most wear. Avoid standing heavy loads or racking legs on the joints and flag chipped arrises before they spread.

An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall and the reseal becomes an edge repair as well. A sound seal keeps the joint working.

Surface by surface

Concrete and precast panel joints

Concrete edges can be weak or carry release agents that stop adhesion. Proper cleaning and primer where specified give a sound bond and check the edges for soundness as we go.

Internal floor movement joints

Floor joints include saw-cut joints and construction joints. A semi-rigid filler is common in trafficked industrial floors and a flexible sealant where the joint moves more.

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. 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.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

How a job runs

Diagnose, treat, sign off: that’s the shape of every visit. 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. Rural sites near Kingham may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. We look at the joints, their width and how they’ve failed.
  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. We check every joint before sign-off, and the work carries our 12-month guarantee.

Before we start on site

  • Flag any permit to work we will need
  • Make sure the joints can be reached
  • Arrange parking or a loading space

When to call us in Kingham

Weathering wears down sealant on exposed elevations and decks. In time the bead chalks, stiffens and cracks.

Common reasons buildings call us in:

  • New sealant over old, now failing
  • Movement joints with split or torn sealant
  • Sealant pulling off the joint face
  • Damp inside where a wall movement joint has failed

For a school such as Kingham Primary School, playground and building joints can be done in the holidays.

Before you book anyone

  • Whether their applicators hold CSCS cards
  • Will RAMS and insurance details be available?
  • Whether old or failed sealant will be cut out, not overlaid
  • Are they CHAS accredited or on Constructionline?
