Expansion joint sealing across Childerditch

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Keeping the joints sound

Problems stay small when the joints are checked regularly. In particular:

  • Include every elevation and deck joint in periodic inspections
  • Avoid parking heavy plant or pallets on joint lines
  • Act on the first tear or lifting edge rather than waiting
  • Keep product details with the building records for the next reseal

Keep wheels, feet and water off new joints until the sealant has cured. How long that takes depends on the product, the temperature and the depth of the joint, and we confirm it for each area before we leave. Barriers left in place until then protect the finish.

Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers. Keeping the filler or sealant sound protects the floor.

About our expansion joint sealing in Childerditch

We cover the full range of movement joints: 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, and we will confirm the choice in the quote. We work on cladding panel joints, blockwork control joints and brickwork movement joints, and the usual reasons a site gets in touch are weathered movement joint sealant that no longer flexes and arrises breaking up along floor joints. A single leaking joint is often how a building in Childerditch first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Smaller community and commercial buildings around Childerditch have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.

Every job we finish is backed by a 12-month workmanship guarantee, in Childerditch as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Leave it or put it right?

Patching the worst lengths of a joint can make sense short term. But if the rest of the run is the same age and product, it’s typically not far behind and repeated access costs add up. Where it helps, we quote both options. Converted and older buildings near places like Childerditch tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Why appoint us

  • Specification-led, product-correct work
  • Colour options checked against the specified product
  • A fixed quote before work starts
  • Commercial sealant work since 2005

Take a look at how commercial sealant jobs are priced and our accreditations and insurance.

What sets the cost

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • How much existing material needs removing
  • Whether the work must be split into stages
  • The size and state of each joint
  • Induction, permit and paperwork requirements

Access can matter as much as the joints themselves: 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.

What to include in your enquiry

It doesn’t need to be a full survey. These details are enough to start:

  • Asbestos survey details if the building is older
  • The product your specification calls for
  • Where the site is, with the postcode
  • Anything awkward about access or site hours

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, ring 01277 525 020 or email a schedule or drawings.

Your questions answered

Is a smaller place like Childerditch outside your area?

No. Small places get the same service as large ones. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

Can you work on a hospital site such as Hartswood Hospital?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

Do you reseal car park expansion joints?

Yes, we do. Tyre loads, grit and de-icing salts make these some of the hardest joints to keep sealed, and we will tell you if any edges need repairing first.

Do the joint edges need to be sound before sealing?

Spalled edges need repairing before a new seal will last, and we will point out where that’s the case. Sealing over them leads to early failure.

How long does movement joint sealing take?

The metres of joint, the access and the amount of removal decide it. As a guide, it usually takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases.

Expansion joint sealing around Childerditch: what changes locally

Rainfall across the South East, Childerditch included, is lower than in many parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and winter de-icing salt on car parks and ramps works into any open joint. Childerditch is about 19 miles from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital; their floors carry heavy traffic every shift.

Schools like Woodlands School Great Warley often have long brick elevations with movement joints that age quietly. Hospital campuses such as Hartswood Hospital (to the north-west of Childerditch) grow in stages, leaving movement joints wherever new blocks meet old.

Childerditch is about 3 miles south of Brentwood, in Essex. Any commercial site in Childerditch is covered, whether it’s a single job or part of a planned programme. 644 places across Essex fall within our area, including Childerditch. London is covered too, some 19 miles away.

How the job changes by surface

Joints between different materials

Different materials meeting at a joint rarely move in step. We choose a sealant that grips both faces.

Podium joints

Podiums take foot traffic, planters and weather. We choose a product that copes with feet, wheels and weather.

Common problems we fix in Childerditch

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.

If one of these sounds familiar, it’s time for a closer look:

  • Previous reseals laid over old sealant
  • Expansion joints filled with dirt and stones
  • Brittle, chalky sealant on external joints
  • Rain penetration at brick or block movement joints

On industrial estates such as Childerditch Industrial Park, which lies south-west of Childerditch, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.

Questions to ask before you book

  • Is the sealant right for the movement and the substrate?
  • How the joint faces will be prepared and primed
  • Will RAMS and insurance details be available?
  • Their approach to joint depth and backing

  4. Edges are checked, and we tell you if any need repairing before sealing.
  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.

Preparing the site
