Expansion joint sealing in Oakley, done properly

Long runs of brick or block have movement joints built in, and they’re easy to miss until the sealant fails. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal comes out, backing goes in and a sealant with the right movement class is applied, primed where the manufacturer specifies. We work on cladding panel joints, car park decks and ramps and brickwork movement joints, and the usual reasons a site gets in touch are sealant pulling off the joint face and layers of sealant in a movement joint. A single leaking joint is often how a building in Oakley first comes to us: we look at the rest while we’re there and tell you what we find.

Around Oakley, most floor and movement joint jobs are single buildings or yards, so we gather photos and measurements first. That way the right materials come on the day and the job is done in one visit where possible.

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.

Signs you need expansion joint sealing in Oakley

Sometimes the sealant holds but the substrate breaks away. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip.

Common reasons buildings call us in:

  • Previous reseals laid over old sealant
  • Car park joints leaking onto vehicles below
  • Brittle, chalky sealant on external joints
  • Arrises breaking up along floor joints

Schools like Mill Lane Community Primary School often have long brick elevations with movement joints that age quietly.

  • Do they follow the manufacturer’s priming guidance?
  • Will RAMS and insurance details be available?
  • Health and safety accreditation such as CHAS
  • What level of public liability insurance do they hold?

Questions we’re asked in Oakley

Can you work at a site such as Junction 5 Bates Industrial Estate, by Oakley?

Yes. Our area takes in Oakley and its surroundings, with estates and business parks such as Junction 5 Bates Industrial Estate included. To start, just ring 01277 525 020 or email us with the unit, the joints involved and your access times.

Would you work within a site like Thame Community Hospital?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Do the joint edges need to be sound before sealing?

Broken arrises have to be put right before resealing, and we will point out where that’s the case. A bead on a broken edge soon lets go.

What causes movement joint sealant to fail?

It depends on how the sealant has let go: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Broken edges are a third possibility.

Is movement joint sealing guaranteed?

Our workmanship on movement joints carries a 12-month guarantee. The guarantee covers how we sealed, not damage caused afterwards.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

When it isn’t the sealant

We check first that sealant really is the fix. It isn’t the answer for:

  • Crumbling edges that would give a new bead nothing sound to grip
  • Cracking or settlement that calls for an engineer’s assessment
  • Proprietary pre-formed expansion joint systems

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

Surfaces we seal

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

Where floor joints take the most wear near Oakley

Oakley is about 38 miles from central London. The roads out of London are lined with trade parks and distribution sheds, and their floor joints take forklift and pallet-truck traffic all day. Oakley 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 gritting in cold spells finds its way into open joints.

On industrial estates such as Junction 5 Bates Industrial Estate, 2.9 miles to the south of Oakley, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic. Hospitals like Thame Community Hospital, 3.8 miles north-west of Oakley, have multi-storey or surface car parks whose joints carry vehicles round the clock.

Oakley is about 4 miles south-east of Thame, in Oxfordshire. We cover Oakley and the rest of Oxfordshire, with the same fixed quotes and 12-month guarantee as everywhere else. Oakley is one of 423 places in Oxfordshire on our list for movement joints. Sites around Oxford have their own page, roughly 14 miles from Oakley.

How the quote is worked out

A fixed quote reflects the actual work. It takes account of:

  • Removal of failed or old sealant
  • Which sealant the job calls for
  • Location, for remote and island sites
  • Induction, permit and paperwork requirements

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Details that help us quote

The more we know, the firmer the quote. When you get in touch, include:

  • Any specification or named product
  • Where the site is, with the postcode
  • Drawings or a marked-up plan, if available
  • When you need the work done

Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings that you can work with. If you have questions first, ring 01277 525 020 or send photos by email.

From enquiry to sign-off

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before the next one starts. For a job in Oakley, the main thing is a clear picture of the work. A fixed quote follows.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. Joint widths and expected movement are checked against what the sealant can take, 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. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Before we start on site

  • Share your working hours and any access restrictions
  • Tell staff and tenants when we’ll be in
  • For older buildings, check the asbestos register before work

Advice

Surface by surface

Concrete and precast panel joints

Concrete edges can be weak or carry release agents that stop adhesion. We prepare the faces thoroughly and prime where the maker calls for it and check the edges for soundness as we go.

Internal floor movement joints

Forklift and pallet-truck wheels break unsupported joint edges. The right filler or sealant for the traffic and movement protects them flagging broken arrises before sealing.
