Floor joint sealing across Northease

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Floor joint sealing in Northease, done properly

We diagnose the floor first rather than guessing at a product: joint widths, whether the joints are still opening, what runs over them and how the edges have held up. From that we choose between a semi-rigid filler and a more flexible sealant and the answer can differ from one zone to the next. We work on joints along racking aisles, loading bays and construction joints, and what we are called in for most is dock area joints that have failed first and filler that has parted from one face. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Northease it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Jobs around smaller places like Northease are planned so the whole job is done in one visit. Note joint widths and the traffic that uses them, and we’ll take it from there.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Work for main contractors and building owners

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Northease can sit alongside others in a wider programme.

CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Honest limits

Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:

  • Level or flatness problems across the floor
  • Damaged or worn floor coatings and screeds
  • Wide or random cracking that suggests a structural issue

Not sure which it is? You can phone 01277 525 020 or email us and we’ll tell you honestly before you book.

Joints and surfaces we work on

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

What happens if it’s left?

Waiting for a site-wide shutdown often means the joints keep getting worse. Phased in zones, the busiest routes can be treated first and the remainder follows on a plan that suits you. Converted and older buildings near places like Northease tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.

Cost factors for floor joints

What shapes the price:

  • How accessible the joints are
  • Whether the work must be split into stages
  • Specialist products, such as fire-rated or hygienic sealants
  • How much existing material needs removing

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

What we need to price the job

We can often quote from photos and a few details. Please tell us:

  • Access details, including height
  • A wide shot and a close-up of the area
  • Specification clauses that apply
  • Asbestos survey details if the building is older

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, call the office on 01277 525 020 or email a schedule or drawings.

From enquiry to sign-off

At the end of each section, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. For work around Northease, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. We walk the floor and mark up joint widths, edge damage and traffic routes.
  2. You receive a fixed quote showing products and phasing.
  3. Old fill and packed debris come out until both faces are sound.
  4. We extract the dust and prime the faces if the product needs it.
  5. Filler or sealant is placed to depth and finished flush.
  6. We hand each phase back when it can take traffic.

What we need from you

  • Share the asbestos register for older buildings
  • Point out parking and an unloading spot
  • Have the specification and drawings to hand

Related advice

What the job involves on each surface

Isolation joints at walls and columns

Joints at walls and columns are often missed when floors are sealed and fill up with dirt. We include them in the survey.

Flexible floor sealants

Polyurethane sealants suit floor joints with larger movement. They give less edge support than semi-rigid fillers, so they suit lighter traffic or movement joints.

Your questions answered

Is Northease too small for you to travel to?

No. Places such as Northease are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Does your area include sites such as Cliffe Industrial Estate, near Northease?

Yes. Estates, retail parks and business parks around Northease, Cliffe Industrial Estate among them, are all within reach. To start, just call the office on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

What site paperwork can you supply?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.

Do you use semi-rigid filler or flexible sealant on floor joints?

It depends on the traffic and the movement. Trafficked joints on truck routes normally need a semi-rigid filler to support the edges, while joints that move more take a flexible sealant.

Can weather delay the job?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Phasing is what makes joint work possible on busy sites such as Phoenix Industrial Estate (2.5 miles north of Northease): one bay, aisle or car park row at a time.
