FAQs: Steyning

Is a smaller place like Steyning outside your area?

No. Places such as Steyning are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Can you work at a site such as Mackley Industrial Estate, by Steyning?

Yes. Estates, retail parks and business parks around Steyning, Mackley Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.

How long before trucks can use the joints?

Cure times vary with the product and the conditions. You’ll get a reopening time for each area before we start.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

How long do sealant joints 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.

Are you CHAS accredited?

Yes. We are CHAS accredited and a Constructionline member.

Should floor joints be filled or sealed?

There isn’t one answer for a whole floor. Where hard wheels cross, a semi-rigid filler is typically right, and movement joints or perimeters need something flexible. The quote sets out what goes where.

How we handle floor joint sealing in Steyning

Before quoting, we look at what the floor is telling us: joint widths, whether the joints are still opening, what runs over them and how the edges have held up. That tells us whether semi-rigid filler or flexible sealant suits each run, area by area where it needs to be. If you’re dealing with flexible sealant torn out by wheels and saw-cut joints left open and packed with grit, we can help, on saw-cut induced joints, forklift and pallet-truck routes and construction joints alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Steyning it comes down to the same thing: the right product in a properly prepared joint.

Rural business units around smaller places such as Steyning often have new slabs laid inside older buildings. Saw-cut and construction joints in those floors need the right filler or sealant for the forklifts and trolleys that use them.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

What we are called out for in Steyning

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.

Look out for the following:

  • Open saw cuts full of debris
  • Brittle joint filler breaking up
  • Scruffy, dirty joint lines on a shop or showroom floor
  • Filler that has parted from one face

If you manage units on an estate such as Mackley Industrial Estate, 2.5 miles to the east of Steyning, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch.

Questions to ask before you book

  • How the joint faces will be prepared and primed
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Will CSCS-carded applicators be on site?
  • Their pre-qualification and accreditations

How to choose a sealant contractor

Floors, slabs and movement joints in Steyning

At about 44 miles from central London, Steyning is within reach of the capital. The roads out of London are lined with trade parks and distribution sheds. Rainfall across the South East, Steyning included, is lower than in many parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and where de-icing salt is spread in winter, open joints let it in.

A healthcare site such as Southlands Hospital (4.4 miles south-east of Steyning) depends on car parks, ramps and service yards whose joints take traffic all day. Schools such as Steyning CofE Primary School have movement joints in their walls and floors that are easy to overlook.

Steyning is about 4 miles north-west of Shoreham-by-Sea, in West Sussex. Any commercial site in Steyning is covered, for single jobs and planned programmes alike. Steyning is one of 373 places we cover in West Sussex for floor joints. There’s a separate page for Brighton, roughly 9 miles from Steyning.

Commercial sites across BN44 are covered. Buildings on High Street, Market Field and Dog Lane are within our area for floor joints. We also cover Bramber (1 mile east), Botolphs (1 mile south-east), Upper Beeding (1 mile east), Sompting (4 miles south) and Findon Valley (4 miles south-west) for floor joints. Further afield, our area takes in Horsham (12 miles north), Worthing (5 miles south-west), Haywards Heath (13 miles north-east), Burgess Hill (10 miles north-east), Littlehampton (10 miles south-west) and Shoreham-by-Sea (4 miles south-east).

What’s near Steyning

Around Steyning, our work takes us to commercial buildings near The Model Bakery The Norfolk Arms and Steyning Grammar School and the streets around them. For rail, the closest station is Lancing station, about 4.1 miles south. A little further out are Steyning Museum (less than half a mile north) and Southlands Hospital (4.4 miles south-east). The countryside around Steyning includes Woods Mill and Chanctonbury Hill.

When to bring in a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

When something else is needed

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Spalled arrises, which need an edge repair first
  • A failing floor coating, which is a flooring contractor’s job
  • Structural cracking in the slab

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

Joints and surfaces we work on

  • Forklift and pallet-truck routes

How a job runs

At the end of each section, 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. What matters most for a job in Steyning is a clear list of what needs doing, so send photos of each area. A fixed quote follows.

  1. First, the zones and order of work are agreed with you.
  2. Any joints with broken edges are flagged before work starts.
  3. Failed material and debris are removed and the joint cleaned.
  4. We fill the joints with the agreed product, finished level.
  5. You get a time for each zone to reopen.

Preparing the site

  • Let building users know which areas are affected
  • Send your site hours and access windows

Advice

Work for main contractors and building owners

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Different surfaces, different methods

Forklift and pallet-truck routes

Joints on busy routes need a fill that sits flush and resists impact. Wheel type and traffic level steer the product choice.

Retail and showroom floors

Retail joints see trolleys, footfall and scrubber-driers. The product is chosen for that traffic and the finish matters as much as the performance.
