Expansion joint sealing for Three Oaks sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Questions we are asked in Three Oaks

Is Three Oaks off your patch?

No. Small places get the same service as large ones. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Does your area include sites such as Ivyhouse Industrial Estate, near Three Oaks?

Yes. Estates, retail parks and business parks around Three Oaks, Ivyhouse Industrial Estate among them, are all within reach. A few photographs and the unit address let us price the work.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Will you come and look before quoting?

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

What exactly is a movement joint?

Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Expansion joint is a name often used for the same thing.

What will the job cost?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote.

What timescale should we allow for resealing expansion joints?

The metres of joint, the access and the amount of removal decide it. As a guide, it 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.

Expansion joint sealing for commercial buildings in Three Oaks

Few joints take as much punishment as those in a car park. Wheel loads, grit and de-icing salts attack the seal and the concrete either side; water dripping through to the deck below is often the first sign. We reseal deck and ramp joints with a trafficable sealant chosen for the movement and the work can be phased so parts of the car park stay open. The enquiries we see most involve expansion joints filled with dirt and stones and leaks through car park deck joints onto the level below, across precast concrete panel joints, podiums and floor movement joints and brickwork movement joints. For commercial sealant work in Three Oaks, you deal with one contact from quote to sign-off, whether it’s one building or several.

In and around smaller places like Three Oaks, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Traffic, movement and joints around Three Oaks

With the shore within about 3 miles, Three Oaks counts as a coastal location. Open joints in coastal car parks and yards let in salt-laden water as well as grit, so a failed joint lets more in and the edges break up sooner. Central London is about 51 miles from Three Oaks. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital.

In a school such as Buckswood School, movement joints in brick, block and hall floors tend to be forgotten until they leak. Hospital campuses such as Conquest Hospital, 2.5 miles to the south-west of Three Oaks, grow in stages, leaving movement joints wherever new blocks meet old.

When to bring in a specialist

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

What sets the cost

What shapes the price:

  • Access and working height
  • Quantities, in metres or numbers
  • Backing rod, priming and other preparation
  • Working within restricted access windows

A quote for movement joints depends on quantities, condition and access. Call for a quote.

Sending details for a quote

For an accurate fixed quote, we need a clear picture of the site. Send us:

  • The asbestos register, for older buildings
  • Whether the building will be occupied during the work
  • A wide shot and a close-up of the area
  • Specification clauses that apply

The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or phone 01277 525 020 or send photos by email if you’d rather talk the job through.

Our process

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For work around Three Oaks, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  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
  • Send any specification or drawings in advance
  • Point out parking and an unloading spot

Honest limits

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Movement on a scale no sealant is meant to absorb
  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • A joint that has to be widened or re-detailed before it can work

Not sure which it is? You can call the office on 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

Joints and surfaces we work on

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

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. We cut out the old seal and prepare the faces every time. Converted and older buildings near places like Three Oaks tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Why us?

  • 12 months’ guarantee on every job
  • Over 20 years of commercial sealing
  • RAL and finish matching where the product range allows
  • Fully insured, including public liability cover

Common problems we fix in Three Oaks

Three-sided adhesion is a common cause of early failure. Bonded on three faces, it can’t stretch evenly when the joint opens so backing is set before sealing.

What tends to prompt an enquiry:

  • Sealant pulling off the joint face
  • Weathered movement joint sealant that no longer flexes
  • Expansion joints filled with dirt and stones
  • Leaks through car park deck joints onto the level below

At places like Wheel Farm Business Park, which lies west of Three Oaks, joints are sealed a section at a time so operations carry on.

What your quote should include

  • Which product they’ll use, and why it suits the joint
  • Will CSCS-carded applicators be on site?
  • What level of public liability insurance do they hold?
  • Their plan for phasing and protecting the area
