How we handle expansion joint sealing in Sheldwich

Mastic Doctor has sealed movement joints since 2005 for contractors, facilities managers and owners. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. If you are dealing with hardened, cracked sealant on exposed facades and sealant peeling off one face of the joint, we can help, on brickwork movement joints, precast concrete panel joints and blockwork control joints alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Sheldwich, that means joint design, primers and backing rod as standard.

Around smaller places such as Sheldwich, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Slabs, ramps and loading bays in Sheldwich

Sheldwich lies roughly 45 miles out from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors, and their floor joints take forklift and pallet-truck traffic all day. Sheldwich sits in one of the drier corners of the country, the South East. External joints still wait for dry conditions, while winter salting gets into any joint left open.

For a school such as Sheldwich Primary School, playground and building joints can be done in the holidays.

What the job involves on each surface

Concrete and precast panel joints

Joints between precast panels open and close with temperature and loading. The sealant needs the right movement capability and a controlled depth.

Joints between different materials

Some mixed-material joints suit a hybrid sealant. We pick the product for the materials and the movement.

FAQs: Sheldwich

What paperwork can you provide for a job in Sheldwich?

Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

Is Sheldwich too small for you to travel to?

Not at all. Sheldwich is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

How long does movement joint sealing take?

Allow a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. We confirm the timescale with the quote along with the phasing plan.

Why has the sealant in our expansion joints split?

The way it has failed usually tells us why: tearing down the centre means too much movement, and lifting off one side means poor adhesion. Broken edges are a third possibility.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

Can you quote from photographs?

It depends on the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.

How soon can the area be used again?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

Common problems we fix in Sheldwich

With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Bonded on three faces, it can’t stretch evenly when the joint opens.

What tends to prompt an enquiry:

  • Arrises breaking up along floor joints
  • Expansion joints filled with dirt and stones
  • Hardened, cracked sealant on exposed facades
  • Water dripping through deck or ramp joints

In and around Sheldwich, the right filler or sealant for each joint depends on the traffic and the movement it takes.

What to look for in a quote

  • The named product and why it was chosen
  • The terms of the workmanship guarantee
  • Whether primer will be used where the manufacturer specifies it
  • Will failed sealant be removed rather than covered?

How to choose a sealant contractor

Maintenance after handover

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Report split or peeling joint sealant early
  • Inspect exposed joints once the cold weather has passed
  • Keep traffic off new joints until the cure time is up
  • Raise snow-clearing blades over deck joints where possible

Grit is the slow enemy of a joint seal. Grit trodden or driven into the joint works at the surface until it tears and decks and floors suffer most. A routine sweep is the simplest protection.

On a multi-storey car park, a failed joint normally shows up as a leak onto the deck underneath. Salty water dripping through stains soffits and lands on parked vehicles. Sealing the joint promptly stops it at source.

How a job runs

Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Rural sites near Sheldwich may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. We look at the joints, their width and how they’ve failed.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. Old sealant and filler are cut out and the joint faces cleaned back to sound material, flagging any broken edges that need repair before sealing.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

Before we start on site

  • Send asbestos survey details if the building is pre-2000
  • Confirm the product named in the specification
  • Agree which areas must stay open

Getting a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Site staff or a sealant specialist?

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

Honest limits

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

  • A joint that has to be widened or re-detailed before it can work
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Damaged metal nosings or cover plates over a joint

If in doubt, ring 01277 525 020 or email us and we will say what we think.

Surfaces we seal

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