Aftercare for building managers

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Include every elevation and deck joint in periodic inspections
  • Brief car park operatives to protect joint lines during winter clearance
  • Report split or peeling joint sealant early
  • Clear dirt from joint lines during routine cleaning

Debris does more harm to joint sealant than most people realise. Grit trodden or driven into the joint works at the surface until it tears and decks and floors suffer most. Regular sweeping keeps joint lines clear.

Unsupported floor joint edges spall under forklift and pallet-truck wheels. Broken arrises jolt trucks, loads and drivers, and the damage spreads along the joint. Sealing early protects the edges.

Send them through our quote form, and we’ll arrange a site visit if needed, then send a fixed quote that names the sealant. To discuss the joints first, call 01277 525 020 or email a schedule or drawings. If you are dealing with chipped joint edges on forklift routes and rain penetration at brick or block movement joints, we can put it right. Facilities teams, main contractors and managing agents in Challock tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Smaller community and commercial buildings around Challock have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.

Commercial clients in Challock

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.

FAQs: Challock

Is Challock off your patch?

No. Places such as Challock are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Does a site in Challock have to shut while its joints are sealed?

Normally not: we work in sections and hand each one back once it has cured. Tell us which hours and entrances we can use and we will plan from there.

What causes movement joint sealant to fail?

Most often the movement is too much for the product or the joint width. We review the joint design as well as the sealant before pricing, rather than replacing like for like.

What if the joint edges are damaged?

Sound edges are essential. Where they’ve broken up, we will tell you they need repairing first.

Who decides which product is used?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

How long do sealant joints last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Can you fit around our working hours?

The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.

Site staff or a sealant specialist?

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.

How the job changes by surface

Internal floor movement joints

Warehouse and retail floors have saw-cut induced joints and construction joints. A semi-rigid filler is common in trafficked industrial floors, with a flexible sealant where movement is larger.

Concrete and precast panel joints

Precast panels often have surface residues that sealant won’t bond to. Proper cleaning and primer where specified give a sound bond.

What we are called out for in Challock

Car park decks and floors face loads that walls never see. Wheel loads stress the sealant and the arrises. A sealant that isn’t trafficable won’t last there.

What tends to prompt an enquiry:

  • Previous reseals laid over old sealant
  • Damp inside where a wall movement joint has failed
  • Arrises breaking up along floor joints
  • Water dripping through deck or ramp joints

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

What to look for in a quote

  • Whether primer will be used where the manufacturer specifies it
  • What the guarantee covers, and for how long
  • Their public liability cover
  • Which product they’ll use, and why it suits the joint

Our contractor checklist

How a job runs

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally 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 Challock can be grouped with others nearby. A fixed quote is given before anything starts.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Getting the site ready

  • Share the asbestos register for older buildings
  • Arrange parking or a loading space
  • Confirm the product named in the specification
