How the job changes by surface

Car park decks and ramps

Failed deck joints often show as leaks on the level below. The old seal comes out, the edges are prepared and the joint resealed flagging broken edges along the way.

Podium joints

On podiums, the joint can belong to a larger waterproofing detail. We reseal the joint where sealant is the specified fix, and tell you if the problem looks like the waterproofing below.

About our expansion joint sealing in Steeple Claydon

Internal floor joints take trolleys, pallet trucks and forklifts. Without a sound filler, joint edges chip and spall under load, so the right filler or sealant for the traffic and movement matters. If the arrises are already broken, we will say so before sealing and phasing can keep areas working. We work on blockwork control joints, brickwork movement joints and precast concrete panel joints, and the usual reasons a site gets in touch are car park joints leaking onto vehicles below and damp inside where a wall movement joint has failed. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Steeple Claydon is the same: the right product in a properly prepared joint.

Rural business units around smaller places such as Steeple Claydon often have new slabs laid inside older buildings. Joints in those slabs need a product suited to whatever runs over them, from pallet trucks to foot traffic.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

What happens if it’s left?

Some quotes just add sealant over the old bead. A bead over the old seal can’t bond or flex and soon lets go. We cut out the old seal and prepare the faces every time. In a smaller place such as Steeple Claydon, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Why appoint us

  • Products installed to the manufacturer’s instructions
  • A Constructionline member, so easy to vet
  • 12 months’ guarantee on every job

Questions we’re asked in Steeple Claydon

Is Steeple Claydon too small for you to travel to?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

Can you work on a hospital site such as Buckingham Community Hospital?

Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.

Are you CHAS accredited?

Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Is movement joint sealing guaranteed?

It’s backed by our 12-month guarantee. If a joint we sealed fails inside the 12 months, let us know.

Can you seal joints in cold or wet weather?

Sealant needs a dry joint and a temperature within the product’s range. Cold, damp or frosty mornings can stop work outside so external dates keep some flexibility.

How a job runs

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on 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. For a site in Steeple Claydon, we plan so the whole job is done in one go where possible. Clear photos and measurements help us bring the right products.

  1. We assess the joints on site or from photographs, noting widths and how each has failed.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Getting the site ready

  • Let building users know which areas are affected
  • Move anything stored against the joints
  • For older buildings, check the asbestos register before work

Quotes

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

What we’re called out for in Steeple Claydon

Some joints were never sealed with the right product. Products not classed for the movement fail early. Movement capability is set out in BS EN ISO 11600.

Common reasons buildings call us in:

  • Chipped joint edges on forklift routes
  • New sealant over old, now failing
  • Leaks through car park deck joints onto the level below
  • Sealant peeling off one face of the joint

Hospital campuses such as Buckingham Community Hospital, 4.5 miles to the north of Steeple Claydon, grow in stages, leaving movement joints wherever new blocks meet old.

Before you book anyone

  • What the guarantee covers, and for how long
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Whether their applicators hold CSCS cards
  • How the existing material will be dealt with

Our contractor checklist

Expansion joint sealing in Steeple Claydon: the local picture

At about 49 miles from central London, Steeple Claydon is within reach of the capital. The South East has large numbers of industrial estates and warehouses along the motorway corridors; their floors carry heavy traffic every shift. Steeple Claydon sits in one of the drier corners of the country, the South East. 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.

If you manage units on an estate such as Three Bridge Mill Industrial Park (1.6 miles west of Steeple Claydon), the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch. For estates staff at a university like University of Buckingham, 3.9 miles north of Steeple Claydon, building and paving joints are part of the planned maintenance list.

Steeple Claydon is about 4 miles south of Buckingham, in Buckinghamshire. Looking for expansion joint sealing in Steeple Claydon? We can help. Across Buckinghamshire, 308 places are covered, including Steeple Claydon. For work in that direction, see our Oxford page (17 miles or so).

Aftercare for building managers

For the best life from the joints:

  • Keep traffic off new joints until the cure time is up
  • Avoid parking heavy plant or pallets on joint lines
  • Inspect movement joints alongside other routine building checks
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints

Floor joints on main traffic routes need watching more closely than the rest. Avoid standing heavy loads or racking legs on the joints.

A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles, which is bad news for the concrete and the people parking below. Sealing the joint promptly stops it at source.
