Floor joint sealing in Dean

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Honest limits

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:

  • A failing floor coating, which is a flooring contractor’s job
  • Broken concrete either side of the joint
  • A floor that rocks at the joints, which needs a structural fix

If you are not sure, just call 01277 525 020 or send photos by email and we will give you a straight answer.

Joints and surfaces we work on

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

About our floor joint sealing in Dean

Some joints reach us with their edges already broken. Filling against a crumbled arris won’t hold for long, so if the edges need repair before any filling, we’ll say so and explain how it affects the programme. If you’re dealing with unfilled floor joints collecting dirt and grit and flexible sealant torn out by wheels, we can help, on loading bays, forklift and pallet-truck routes and saw-cut induced joints alike. For commercial sealant work in Dean, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Halls, schools and small commercial buildings near places like Dean have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.

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

Leave it or put it right?

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. Older rural buildings around Dean move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

What you get with us

  • Health and safety: CHAS accredited
  • Our applicators hold CSCS cards
  • Workmanship guaranteed for 12 months
  • Fully insured, including public liability cover

Floor joint sealing around Dean: what changes locally

Less than 3 miles from Dean there are two named estates and business parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. The South East is one of the drier parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and where de-icing salt is spread in winter, open joints let it in.

Across sites such as Waltham Business Park, which lies south of Dean, floor and movement joints can be sealed in phases so units keep working. For a school such as Bishops Waltham Infant School, playground and building joints can be done in the holidays.

Quoting for work in Dean

We price every job individually. The main factors are:

  • Site requirements such as inductions and permits
  • Access and working height
  • The size and state of each joint
  • Quantities, in metres or numbers

Pricing floor joints depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.

Sending details for a quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • Access details, including height
  • Specification clauses that apply
  • Photos of the joints, close up and from further back
  • Rough lengths or quantities, or drawings if you have them

To get a fixed quote, give us a call on 01277 525 020 or email drawings and photos. Our quote form is another easy route.

Diagnose, treat, sign off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For work around Dean, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. We agree the traffic routes and phasing with your site team.
  2. We point out joints whose edges need repairing first.
  3. We clear each run back to clean concrete.
  4. We fill the joints with the agreed product, finished level.
  5. You get a time for each zone to reopen.

Before we start on site

  • Have the specification and drawings to hand
  • Tell us your opening times and when work is allowed
  • Explain the parking and delivery arrangements

Getting a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.

FAQs: Dean

Is Swanmore Business Park, near Dean, within your area?

Yes, sites like Swanmore Business Park are within our area, along with the rest of Dean. Photos and a short description are enough for a first look.

Must our site in Dean stop work while the joints are done?

Usually not: we work in sections and hand each one back once it has cured. The phasing plan comes with the quote.

How many days will you need on site?

The duration is planned around your programme and the access we are given. You will have an expected duration with the quote.

How long will the new sealant last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Why is there a gap next to the joint filler?

Separation typically comes from slab shrinkage, poor preparation or the wrong product. We look at which it is before recommending anything.

Is Dean in your area?

Yes. Dean falls within our area, and the simplest way to start is to phone 01277 525 020 or email us.

Is colour matching possible?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.

Different surfaces, different methods

Isolation joints at walls and columns

Where racking or plant sits near column joints, access is agreed before we start so nothing has to move unexpectedly.

Retail and showroom floors

We plan shop-floor work so trading can continue. Give us your opening pattern and access windows and the phasing follows.

Common problems we fix in Dean

Small, hard wheels put a lot of load through a very small area. Where a joint is open, the wheel dips and strikes the far edge, and repeated impacts break the concrete away.

Things that usually lead to an enquiry:

  • Dock area joints that have failed first
  • Broken arrises where pallet trucks cross
  • Drivers complaining about joints on a route
  • Scruffy, dirty joint lines on a shop or showroom floor

Business parks such as Swanmore Business Park (to the south of Dean) have car parks, paved areas and long brick and panel elevations, all with movement joints.

Before you book anyone

  • Are they CHAS accredited or on Constructionline?
  • How the existing material will be dealt with
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • How the joint faces will be prepared and primed
