What the job involves on each surface

Internal floor movement joints

Floor joints include saw-cut joints and construction joints. A semi-rigid filler is common in trafficked industrial floors and a flexible sealant where the joint moves more.

Concrete and precast panel joints

Concrete edges can be weak or carry release agents that stop adhesion. Proper cleaning and primer where specified give a sound bond, so the new seal holds.

Your questions answered

Is a smaller place like Chazey Heath outside your area?

Not at all. Chazey Heath 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.

Do you cover business parks and estates near Chazey Heath, such as Oxford Road Business Park?

Yes. Our area takes in Chazey Heath and its surroundings, with estates and business parks such as Oxford Road Business Park included. A few photos and the unit address let us price the work.

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day.

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Is movement joint sealing guaranteed?

The 12-month guarantee applies to the workmanship. If a joint we sealed fails inside the 12 months, let us know.

How much does the work cost?

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

When something else is needed

Honesty saves time and money. New sealant won’t cure:

  • Leaks coming from the membrane rather than the joint seal
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Movement on a scale no sealant is meant to absorb

Not sure which it is? You can call 01277 525 020 or email the details over and we’ll tell you honestly before you book.

On site: what to expect

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases, and our waste is bagged and taken away as we go. Smaller jobs around Chazey Heath can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. We look at the joints, their width and how they’ve failed.
  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, and we tell you if any edges need repairing first.
  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. We check every joint before sign-off, and the work carries our 12-month guarantee.

What we need from you

  • Have the specification and drawings to hand
  • Arrange parking or a loading space
  • Flag any permit to work we will need

When to bring in a specialist

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

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.
