Crockleford Heath: questions and answers

Is Crockleford Heath too far out for you?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Is hospital work, at somewhere like Colchester General Hospital, something you do?

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

Can you work on car park ramps and decks?

Yes. Let us know the opening hours and which levels or bays have to stay available.

What do you charge?

Each job is quoted on its own details. For yours, give us a call on 01277 525 020 or send photos by email with a description of the work.

Do you take on small jobs?

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

What happens if it rains on the day?

The joint has to be dry, and the air and surface temperature inside the product’s limits. Cold, damp or frosty mornings can stop work outside so external dates keep some flexibility.

Are expansion joints and movement joints the same thing?

The general name is movement joint, and expansion joint is one common type. On site, people tend to use them interchangeably and the way they’re sealed is similar.

About our expansion joint sealing in Crockleford Heath

Every structure moves a little, all the time: temperature, moisture, shrinkage and loading all make materials grow and shrink. Expansion and movement joints are built in so the structure can move without cracking, and the sealant in them keeps water and debris out. We seal and reseal movement joints in walls, panels, decks and floors on sites in Crockleford Heath. Site teams most often ask us about hardened, cracked sealant on exposed facades and new sealant over old, now failing, on car park decks and ramps, podiums and floor movement joints and blockwork control joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Crockleford Heath it comes down to the same thing: the right product in a properly prepared joint.

Smaller community and commercial buildings around Crockleford Heath 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. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Different surfaces, different methods

Joints between different materials

Hybrid or MS polymer sealants bond to many substrates. The choice depends on the substrates and how much the joint moves.

Car park decks and ramps

Deck and ramp joints take tyre loads, grit and de-icing salts. A trafficable sealant suited to the movement goes in with bays done in phases so the car park keeps running.

When to bring in a specialist

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

When something else is needed

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Leaks coming from the membrane rather than the joint seal
  • Changing the joint layout or spacing of a structure
  • Broken or spalled joint edges, which need repairing before any sealant goes in

If in doubt, phone 01277 525 020 or email a schedule or drawings and we’ll say what we think.

What we seal

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

On site: what to expect

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. Jobs in and around smaller places like Crockleford Heath are normally planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. We strip out the old seal and prepare the faces.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. Finished joints are checked and backed by our 12-month guarantee.

Preparing the site

  • Warn occupants and staff about the work
  • Let us know about inductions and permits
  • Move anything stored against the joints

Advice

Quoting for work in Crockleford Heath

To price the job, we consider:

  • How much existing material needs removing
  • The site’s rules and procedures
  • Backing rod, priming and other preparation
  • Quantities, in metres or numbers

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Before you send an enquiry

A good diagnosis starts with the right details. Tell us:

  • Photos of the joints, close up and from further back
  • Any specification or named product
  • Where the site is, with the postcode
  • The asbestos register, for older buildings

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Common problems we fix in Crockleford Heath

On trafficked joints, wheels and salts do the damage. Wheel loads stress the sealant and the arrises, while grit and salts work into any gap. A sealant that isn’t trafficable won’t last there.

Site and facilities staff are often the first to spot these:

  • Spalled or broken joint edges in floors and decks
  • Rain penetration at brick or block movement joints
  • Expansion joints split through the centre of the bead
  • Joints where the bead has lost adhesion

At places like Hunwicke Shopping Centre (1.4 miles south-west of Crockleford Heath), joints are sealed a section at a time so operations carry on.

Comparing quotes

  • Whether old or failed sealant will be cut out, not overlaid
  • Proof of insurance
  • Whether primer will be used where the manufacturer specifies it
  • How joint depth will be controlled
