Floor joint sealing across Howt Green

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

When it isn’t the sealant

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Broken concrete either side of the joint
  • A failing floor coating, which is a flooring contractor’s job
  • Cracks across panels caused by settlement or overload

If in doubt, call the office on 01277 525 020 or email us and we’ll say what we think before you book.

Surfaces we seal

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

About our floor joint sealing in Howt Green

Sometimes the concrete either side of a joint has already spalled. A filler laid against broken edges has nothing sound to grip, so if the edges need repair before any filling, we will say so and leave that decision with you. If you’re dealing with soft sealant dragged out of trafficked joints and saw-cut joints left open and packed with grit, we can help, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Howt Green, that means joint design, primers and backing rod as standard.

In and around smaller places like Howt Green, 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.

The 12-month guarantee is for workmanship rather than 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.

Floors, slabs and movement joints in Howt Green

With the shore within about 2 miles, Howt Green counts as a coastal location. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, so a failed joint lets more in and the edges break up sooner. Howt Green sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, and gritting in cold spells finds its way into open joints.

Schools like Regis Manor Primary School often have long brick elevations with movement joints that age quietly. Hospital campuses such as Sittingbourne Memorial Hospital (1.9 miles south of Howt Green) grow in stages, leaving movement joints wherever new blocks meet old.

Howt Green is about 1 mile north-west of Sittingbourne, in Kent. We cover commercial sites throughout Howt Green. Across Kent, 931 places are covered, Howt Green among them. Sites around London have their own page, about 36 miles away.

What sets the cost

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • How much there is to seal
  • Any access equipment needed
  • Whether the work must be split into stages
  • Backing rod, priming and other preparation

Pricing floor joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

What to include in your enquiry

There’s no need for a formal survey. These details are enough to start:

  • Drawings or a marked-up plan, if available
  • Clear photographs of the problem areas
  • The product your specification calls for
  • The type of building and who uses it

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to speak to us on 01277 525 020 or send photos by email with what you know.

Why deal with it now?

An open joint is a modest filling job while its edges are sound. Left until they break, it needs an edge repair before any filling can start which means more downtime in that zone. Around Howt Green, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.

Why us?

  • Old sealant cut out, never sealed over
  • Workmanship guaranteed for 12 months
  • Fully insured
  • Work to your specification and the manufacturer’s guidance

Questions we are asked in Howt Green

Our building in Howt Green is near the coast: does that change the sealant?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Is hospital work, at somewhere like Sittingbourne Memorial Hospital, something you do?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

How soon can traffic go back on the floor?

Each product has its own cure time, and cold floors slow it down. Phasing is planned with that in mind.

What about RAMS and site documents?

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

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Is it fine to apply new sealant on top of old?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Diagnose, treat, sign off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. If others near Howt Green need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. First, the zones and order of work are agreed with you.
  2. Any joints with broken edges are flagged before work starts.
  3. We clear each run back to clean concrete.
  4. The chosen filler or sealant goes in flush with the slab.
  5. You get a time for each zone to reopen.

Getting the site ready

  • Arrange parking or a loading space
  • Tell us your opening times and when work is allowed
  • Confirm the product named in the specification

Doing it in-house

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Common problems we fix in Howt Green

Joints near dock doors see colder air, rain blown in and water off vehicles, as well as the tightest turning loads. They are often the first on a site to break down.

What tends to prompt an enquiry:

  • Joint fill separating from the concrete
  • Chipped and spalling edges along forklift routes
  • Dock area joints that have failed first
  • Unfilled floor joints collecting dirt and grit

Across sites such as Newington Industrial Estate, 3 miles to the west of Howt Green, floor and movement joints can be sealed in phases so units keep working.

Comparing quotes

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Who will actually carry out the work
  • Will failed sealant be removed rather than covered?
  • Is the sealant right for the movement and the substrate?
