Floor joint sealing for Charlton sites

Floor joint sealing in Charlton, done properly

Most industrial slabs are divided into panels by saw-cut joints and construction joints, and every one of those joints is an exposed edge under hard wheels. Our job is to put the right filler or sealant into them for the loads and the movement they see, so the arrises are supported and grit stays out. If you have grimy joint lines spoiling a showroom floor and saw-cut joints left open and packed with grit, we can put it right. A specialist sealant contractor works differently from a general builder: on jobs in Charlton, preparation and product choice get the time they need.

In and around smaller places like Charlton, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, speak to us on 01277 525 020 or email a schedule or drawings and we’ll come back to it.

What we can’t put right

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Structural cracking in the slab
  • Unstable slabs moving under traffic
  • Worn screed or surface finishes

Not sure which it is? You can ring 01277 525 020 or send photos by email and we will tell you honestly.

Surfaces we seal

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

Our process

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For work around Charlton, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. First, the zones and order of work are agreed with you.
  2. We point out joints whose edges need repairing first.
  3. We clear each run back to clean concrete.
  4. The chosen filler or sealant goes in flush with the slab.
  5. Each area is handed back when ready for traffic.

What we need from you

  • Tell staff and tenants when we will be in
  • Send your site hours and access windows
  • Send any specification or drawings in advance

Owners, agents and contractors

Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

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.

What happens if it’s left?

Not every joint needs stripping out completely. If old material is sound on one face and only a fine gap has opened, it may not all have to come out and the quote shows which approach suits each run. For buildings around smaller places like Charlton, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

What you get with us

  • CHAS accredited
  • One contact handling all your sites
  • Failed material removed, not covered up
  • Clear, fixed quotes

How the job changes by surface

Semi-rigid joint fillers

A semi-rigid fill can separate along one side while a slab is still shrinking. That is normally dealt with by topping up later, and we will explain it when we quote.

Flexible floor sealants

Movement joints, joints at walls and joints in lightly trafficked areas often take a flexible sealant. Backing rod limits how deep the bead goes and keeps it off the joint bottom.

Common problems we fix in Charlton

An ageing filler or sealant can go brittle and split, particularly where cleaning machines and traffic work it daily. Once it has gone hard or come loose, it protects nothing.

These are often picked up first by site or facilities staff:

  • Unfilled floor joints collecting dirt and grit
  • Untidy open joints in a retail unit
  • Broken arrises where pallet trucks cross
  • Brittle joint filler breaking up

A healthcare site such as Andover War Memorial Hospital (to the south-east of Charlton) depends on car parks, ramps and service yards whose joints take traffic all day.

Questions to ask before you book

  • Health and safety accreditation such as CHAS
  • How joint depth will be controlled
  • Will RAMS and insurance details be available?
  • How long is the guarantee, and what does it include?

Choosing a commercial sealant contractor

Traffic, movement and joints around Charlton

At about 64 miles from central London, Charlton is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital; their floors carry heavy traffic every shift. The South East is one of the drier parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints.

Phasing is what makes joint work possible on busy sites such as Portway Industrial Estate (0.8 miles south-west of Charlton): one bay, aisle or car park row at a time. For a centre such as Enham Arch Retail Park, 1.1 miles to the east of Charlton, the service yard and car park joints usually need attention first.

Charlton is about 1 mile north-west of Andover, in Hampshire. Any commercial site in Charlton is covered, for single jobs and planned programmes alike. We work across 723 places in Hampshire, large and small. We also cover Southampton, around 22 miles from Charlton.

Close to Charlton, our area also takes in Foxcotte (1 mile north-west), Penton Mewsey (1 mile west), Penton Corner (1 mile west), Penton Grafton (1 mile west) and Red Post Bridge (2 miles south-west).

Charlton: questions and answers

Would you work within a site like Andover War Memorial Hospital?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Does your area include sites such as Mylen Road Business Park, near Charlton?

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

Will we need to close the floor?

The work is phased. We work aisle by aisle or zone by zone so the rest of the floor stays in use around the site hours and access windows you give us.

How do we get a quote for floor joints?

A rough joint length, a few photos and a site plan let us give a quick quote. For larger floors, a site visit is often best so call 01277 525 020 or email drawings and photos to set one up.

When is resealing likely to be due?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Does weather matter for sealant work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

How long does a typical visit take?

We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
