Common questions from Fawkham Green clients

Is hospital work, at somewhere like Darent Valley Hospital, something you do?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is Heaver Farm Trading Estate, near Fawkham Green, within your area?

Yes. We cover Fawkham Green and the area around it, including industrial estates, business parks and retail parks such as Heaver Farm Trading Estate. A few photos and the unit address let us price the work.

Will we need to close the floor?

We phase it. Areas are taken out of use a section at a time around the site hours and access windows you give us.

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Are you CHAS accredited?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

Are your applicators CSCS-carded?

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

Do you guarantee industrial floor joints?

There is a 12-month guarantee on our workmanship, and we hold public liability insurance.

About our floor joint sealing in Fawkham Green

Open joints take a beating from forklift and pallet-truck wheels. Every pass chips at the bare concrete edge until a crisp saw cut becomes a wide, broken groove. A properly filled joint carries the wheel over and protects both arrises, which is kinder to trucks, loads and operators. We work on saw-cut induced joints, loading bays and construction joints, and what we’re called in for most is brittle joint filler breaking up and grimy joint lines spoiling a showroom floor. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Fawkham Green is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For a site near Fawkham Green, measurements and photographs up front mean one trip where possible. Tell us the joint widths if you can, and what drives or walks over them.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

How a job runs

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. Jobs in and around smaller places like Fawkham Green are typically planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. Each area is assessed for joint width, arris damage and the wheels that cross it.
  2. The quote fixes the price, names the filler or sealant and shows how the floor will be zoned.
  3. Old filler, debris and contamination are cut or routed out back to clean concrete.
  4. We vacuum each run and prime it if the chosen product requires a primer.
  5. We fill each joint to depth and finish it flush so wheels roll straight across.
  6. Each phase reopens when the product is ready for wheels, then we start the next.

Getting the site ready

  • Warn occupants and staff about the work
  • Make sure the joints can be reached

Advice

Different surfaces, different methods

Saw-cut induced joints

Sawn joints make up most of the joint length in a typical industrial floor. Each one is cleaned out and filled to the specified depth, finishing flush with the slab.

Loading bays and dock areas

We usually work through dock areas a few bays at a time so goods in and out carry on. Your site hours and access windows set the order.

Work for main contractors and building owners

When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Site staff or a sealant specialist?

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

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Maintenance after handover

Regular inspection catches problems early. In particular:

  • Mention any aggressive cleaning regime at quote stage
  • Ask drivers not to drag forks or pallets
  • Treat loading bay joints first if they’re failing
  • Allow for topping up joints as a new slab settles

If a joint we filled starts to break up within 12 months, tell us and we will arrange a look. After that, a check before your busiest period keeps small repairs small.

Edges tend to break slowly at first, then quickly. Each chip makes the drop deeper and the next impact harder so early treatment saves a lot of trouble.

When it isn’t the sealant

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

  • A floor that rocks at the joints, which needs a structural fix
  • A failing floor coating, which is a flooring contractor’s job
  • Joint edges that have already broken away, which need repairing before filling (we’ll tell you if so)

If in doubt, give us a call on 01277 525 020 or email us and we will say what we think before you book.

Surfaces we seal

  • Forklift and pallet-truck routes
  • Saw-cut induced joints
  • Loading bays
  • Joints along racking aisles
  • Construction joints
  • Retail and showroom floors
