Expansion joint sealing in Penton Mewsey, done properly

Internal floor joints take trolleys, pallet trucks and forklifts. Unsupported edges break up under wheels so the product has to suit both the traffic and the movement. We’ll tell you if the edges need repairing before sealing, and phased work keeps areas in use. The enquiries we see most involve previous reseals laid over old sealant and expansion joints split through the centre of the bead, across brickwork movement joints, cladding panel joints and precast concrete panel joints. For commercial sealant work in Penton Mewsey, you deal with one contact from quote to sign-off, whether it’s one building or several.

In and around smaller places like Penton Mewsey, the concrete floors we see are often in converted farm buildings, small workshops and storage units. 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 the quote explains what it covers.

How a job runs

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. If others near Penton Mewsey need work, visits can be combined. You’ll have a fixed quote before work starts.

  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 tell you if the design looks wrong for the movement.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

What we need from you

  • Clear stock, furniture or equipment away from the joints
  • Warn occupants and staff about the work
  • Tell us your opening times and when work is allowed

Signs you need expansion joint sealing in Penton Mewsey

Weathering wears down sealant on exposed elevations and decks. UV hardens the surface, and the sealant loses its ability to stretch.

Any of the following is a good reason to get the joints checked over:

  • Rain penetration at brick or block movement joints
  • Debris jammed in movement joints
  • Chipped joint edges on forklift routes
  • Torn sealant in brick or block movement joints

Hospitals like Andover War Memorial Hospital, 1.7 miles south-east of Penton Mewsey, have multi-storey or surface car parks whose joints carry vehicles round the clock.

Our contractor checklist

Should maintenance staff do it?

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 usually costs more in the end than doing them right.

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. That’s why many clients bring in a specialist from the beginning.

Looking after the joints

After handover, these steps help:

  • Keep product details with the building records for the next reseal
  • Act on the first tear or lifting edge rather than waiting
  • Include every elevation and deck joint in periodic inspections
  • Keep stones and debris out of open joint lines

On car parks, winter clearance can damage deck joint sealant. Raising blades over joints where possible protects the seal, and it’s worth checking joints once the cold weather has passed.

When one joint fails, others of the same age are rarely far behind. Inspecting the whole run is worth the effort. We’ll tell you which movement joints need doing now and which can wait.

Questions we’re asked in Penton Mewsey

Does your area include sites such as Portway Industrial Estate, near Penton Mewsey?

Yes. Our area takes in Penton Mewsey and its surroundings, with estates and business parks such as Portway Industrial Estate included. A few photographs and the unit address let us price the work.

Do you take on work at healthcare sites like Andover War Memorial Hospital?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Are you CHAS accredited?

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

Do you reseal car park expansion joints?

Yes. We use a sealant designed for wheel loads and the expected movement, and phased work can be planned so parts of the car park stay in use.

Do you seal on top of existing sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Why has the sealant in our expansion joints split?

The common causes are poor preparation, three-sided adhesion, the wrong movement class and weathering. We diagnose which one it is before resealing since each needs a different fix.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
