Questions we are asked in Southington

Is Southington off your patch?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Can you work at a site such as Ardglen Industrial Estate, by Southington?

Yes. We cover Southington and the area around it, including industrial estates, business parks and retail parks such as Ardglen Industrial Estate. Photos and a short description are enough for a first look.

How long does a job like this take?

It depends on the scope, but the work normally takes between a day and a number of days, set by the joint lengths, the edge condition and the phasing you need. For bigger or phased jobs, we’ll set out a timescale with the quote.

Why is there a gap next to the joint filler?

Young concrete carries on shrinking for a long time, so a semi-rigid filler can part from one face. It is typically dealt with by topping up.

Which sealant will you use?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

What information helps you price floor joint sealing?

Use our quote form, or email photos and a plan and tell us what runs on the floor. A fixed quote follows that shows the products and zones.

Are you CHAS accredited?

Yes. We are CHAS accredited and a Constructionline member.

Floor joint sealing in Southington

Few warehouses can shut a whole floor while joints are done, so the work is split into zones and treated one area at a time. Share your site hours and access windows and the programme is built around them, with goods still moving in the areas we aren’t in. We work on loading bays, construction joints and retail and showroom floors, and the usual reasons a site gets in touch are a gap opening alongside old joint filler and cracked and crumbling joint fill. Most enquiries from Southington start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Halls, schools and small commercial buildings near places like Southington have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Cost factors for floor joints

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • Quantities, in metres or numbers
  • Working within restricted access windows
  • The site’s rules and procedures
  • Location, for remote and island sites

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

What we need to price the job

Diagnosis starts before we arrive. Tell us:

  • Specification clauses that apply
  • How the joints are reached, and at what height
  • The asbestos register, for older buildings
  • Drawings or a marked-up plan, if available

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.

Common problems we fix in Southington

Oil, laitance, dust and old cleaning chemicals build up inside joints. If the faces aren’t taken back to clean concrete first, the new material simply lifts out.

It’s worth sending us details if you spot any of the following:

  • Old filler gone hard, cracked or loose
  • Drivers complaining about joints on a route
  • Untidy open joints in a retail unit
  • Sealant pulled out along a truck route

Estates like Ardglen Industrial Estate (3 miles west of Southington) combine warehouse slabs, yards and loading bays, all with joints under wheels.

Comparing quotes

  • How they handle RAMS and site documents
  • Whether primer will be used where the manufacturer specifies it
  • Will failed sealant be removed rather than covered?
  • Are they CHAS accredited or on Constructionline?

Questions to ask before you appoint anyone

Diagnose, treat, sign off

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs in and around smaller places like Southington are usually planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. We look at joint widths, edge condition and the traffic on each route.
  2. A fixed quote follows, listing the treatment for each area and the order of work.
  3. Each joint is cleared of old fill and dirt and taken back to clean, sound edges.
  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. We tell you when each zone can carry trucks again and move on to the next.

What we need from you

  • Share the asbestos register for older buildings
  • Point out any areas we must not close
  • Confirm the product named in the specification

Should maintenance staff do it?

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

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.

What the job involves on each surface

Saw-cut induced joints

Open saw cuts collect grit and break at the arris. Filling them early keeps them tidy and protects the edges.

Flexible floor sealants

Where joints move more, a flexible polyurethane floor sealant is often used. They don’t hold the arrises up as firmly as a semi-rigid fill, so they suit lighter traffic or movement joints.

Where floor joints take the most wear near Southington

Southington sits in one of the drier corners of the country, the South East. Even so, yard and car park joints are only sealed when they’re dry and clean, and where de-icing salt is spread in winter, open joints let it in. At about 54 miles from central London, Southington is within reach of the capital. The South East has large numbers of industrial estates and warehouses along the motorway corridors.

Schools like Overton Church of England Primary School often have long brick elevations with movement joints that age quietly.
