Common questions from Handcross clients

Do you take on work at healthcare sites like Crawley Hospital?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is Handcross too far out for you?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

What happens if the joint edges are damaged?

Filling against broken edges doesn’t last. If the arrises have spalled, we’ll say they need repair before filling, so you can decide how to proceed.

Will we need to close the floor?

In the majority of cases, just the area being treated is coned off. Traffic returns to each zone once it has cured, then we move to the next.

Are you CHAS accredited?

Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

What guarantee do you give on joint filling?

Our workmanship carries a 12-month guarantee and the work is covered by public liability insurance.

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

We decide joint by joint. Hard wheels need edge support, which points to a semi-rigid filler, and movement joints or perimeters need something flexible. The quote sets out what goes where.

Floor joint sealing in Handcross, done properly

Across Handcross and the rest of West Sussex, it runs the same way: send details, get a fixed quote, we seal, and the work is guaranteed. A rough length of joint, photographs of the worst areas and a site plan let us give a quick quote and a visit can be arranged where that is easier. We work on construction joints, joints along racking aisles and saw-cut induced joints, and what we are called in for most is loading bay joints breaking down and a gap opening alongside old joint filler. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Handcross, that means joint design, primers and backing rod as standard.

In and around smaller places like Handcross, 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.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Diagnose, treat, sign off

Before we leave any area, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. If others near Handcross need work, visits can be combined. You will have a fixed quote before work starts.

  1. We agree the traffic routes and phasing with your site team.
  2. We point out joints whose edges need repairing first.
  3. Failed material and debris are removed and the joint cleaned.
  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

  • Share your working hours and any access restrictions
  • Clear stock, furniture or equipment away from the joints
  • Agree which areas must stay open

Surface by surface

Retail and showroom floors

In retail, joints take trolleys, castors and cleaning machines rather than forklifts. We pick a filler or sealant to suit and the finish matters as much as the performance.

Semi-rigid joint fillers

For trafficked warehouse joints, semi-rigid fillers are common. We place them to depth and trim them level with the slab.

How the quote is worked out

We price every job individually. The things that drive the figure:

  • Location, for remote and island sites
  • How much existing material needs removing
  • Site requirements such as inductions and permits
  • Joint width, depth and condition

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

What we need to price the job

A few photos plus some basic facts will normally do. Please tell us:

  • Whether the building will be occupied during the work
  • The site address and postcode
  • How the joints are reached, and at what height
  • Any dates the work must fit around

A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or call 01277 525 020 or email the details over if you’d rather talk the job through.

Aftercare for building managers

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Remind operators to lift rather than drag
  • Photograph any joint that starts to chip
  • Check joint lines on busy aisles regularly
  • Put loading bays at the top of the list

We will give you a time before trucks can run over the new joints, and it’s worth enforcing. In a busy building, barriers keep early traffic away.

While the concrete edges are intact, it’s a filling job. Once they have broken away, edge repair comes first, with more downtime and more disruption.

Slabs, ramps and loading bays in Handcross

Handcross is about 31 miles from central London. Warehousing clusters around the motorways that ring and radiate from London, and their floor joints take forklift and pallet-truck traffic all day. Rainfall across the South East, Handcross included, is lower than in many parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open.

Schools such as Handcross Primary School have movement joints in their walls and floors that are easy to overlook. Large sites such as Crawley Hospital (4.3 miles north of Handcross) have car parks, service roads and long elevations with movement joints in brick and panels. On a site such as Tilgate Forest Business Centre (2.7 miles north of Handcross), the movement joints are in car park slabs, paving and building elevations.

Handcross is about 4 miles south of Crawley, in West Sussex. We send applicators to Handcross for floor joints. 373 places across West Sussex fall within our area, including Handcross. We also cover Brighton, some 16 miles away.

Sites close to Handcross are covered too, including Slaugham (1 mile south), Plummers Plain (2 miles south-west), Colgate (3 miles north-west), Broadfield (3 miles north) and Lower Beeding (3 miles south-west). Bigger towns within reach include Crawley (4 miles north), Horsham (5 miles west), Haywards Heath (6 miles south-east), Burgess Hill (7 miles south-east), East Grinstead (10 miles north-east) and Shoreham-by-Sea (15 miles south).

Site staff or a sealant specialist?

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

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.

What we can’t put right

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

  • Cracks across panels caused by settlement or overload
  • Level or flatness problems across the floor
  • Unstable slabs moving under traffic

If in doubt, call the office on 01277 525 020 or send details through our quote form and we’ll say what we think.
