Expansion joint sealing in Caulcott, done properly

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. The product depends on the movement, the weather and anything that runs over it. If you’re dealing with joints packed with grit and debris and brittle, chalky sealant on external joints, we can help, on brickwork movement joints, cladding panel joints and podiums and floor movement joints alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Caulcott is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Halls, schools and small commercial buildings near places like Caulcott have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

How the job changes by surface

Joints between different materials

Junctions between brick and render, or concrete and cladding, move independently. The product must bond to both substrates and cope with the movement priming where the maker calls for it.

Podium joints

Podium joints often sit within a waterproofing system. Where the specification calls for sealant, we reseal and flag it if the membrane looks like the source.

Work for main contractors and building owners

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

FAQs: Caulcott

Does your area include sites such as Hatch End Old Industrial Estate, near Caulcott?

Yes. Our area takes in Caulcott and its surroundings, with estates and business parks such as Hatch End Old Industrial Estate included. Photos and a short description are enough for a first look.

Do you take on work at healthcare sites like Bicester Community Hospital?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Will you come and look before quoting?

That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs normally get a visit.

What’s the quickest route to a quote?

You can use the quote form on this site; alternatively, ring 01277 525 020 or email a schedule or drawings. Include photographs or drawings if you have them.

Will you quote for a small job?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Do the joint edges need to be sound before sealing?

Sound edges are essential. Where they’ve broken up, we’ll tell you they need repairing first so you’re not paying for a bead that won’t hold.

What hours do you work?

The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.

What we are called out for in Caulcott

Sealant peeling cleanly off one side is an adhesion failure. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes, and it’s common on joints sealed in a hurry.

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

  • Leaks through car park deck joints onto the level below
  • Expansion joints split through the centre of the bead
  • Arrises breaking up along floor joints
  • Rain penetration at brick or block movement joints

Hospital campuses such as Bicester Community Hospital, 4.6 miles to the east of Caulcott, grow in stages, leaving movement joints wherever new blocks meet old.

Before you book anyone

  • The named product and why it was chosen
  • What the guarantee covers, and for how long
  • How they handle RAMS and site documents
  • Are they CHAS accredited or on Constructionline?

Questions to ask before you appoint anyone

Why it’s worth doing now in Caulcott

Patching the worst lengths of a joint can make sense short term. The remaining sealant is often close to failing too. We can price a patch and a full reseal side by side. Converted and older buildings near places like Caulcott tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

Why us?

  • Failed material removed, not covered up
  • Matching to RAL references, product permitting
  • Clear, fixed quotes
  • Products installed to the manufacturer’s instructions

On site: what to expect

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing, and our waste is bagged and taken away as we go. For a building around Caulcott, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

What we need from you

  • Share your working hours and any access restrictions
  • Agree which areas must stay open
  • Send asbestos survey details if the building is pre-2000

What we can’t put right

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:

  • Joints too narrow for the movement, which need redesigning by the engineer
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Crumbling edges that would give a new bead nothing sound to grip

If you are not sure, just ring 01277 525 020 or email us and we’ll give you a straight answer before you book.

Joints and surfaces we work on

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

Traffic, movement and joints around Caulcott

On industrial estates such as Hatch End Old Industrial Estate, which lies north-west of Caulcott, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.
