FAQs: Sharpthorne

Is a smaller place like Sharpthorne outside your area?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Is hospital work, at somewhere like Queen Victoria Hospital, something you do?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

How many days will you need on site?

It depends on the scope, but the work typically takes a day or more, depending on the metres of joint and how many zones the floor is split into. For bigger or phased jobs, we’ll set out a timescale with the quote.

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

It depends on the traffic and the movement. Forklift routes generally call for a semi-rigid filler that holds the arrises, while joints that move more take a flexible sealant.

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Can you fill joints where the arrises have spalled?

We check the edges as part of the survey. Damaged edges are flagged up front, so nothing is filled that won’t hold.

How do we get a quote for floor joints?

Approximate metres of joint, photographs of typical and worst areas, and a floor plan are normally enough for a quick quote. For larger floors, a site visit is often best, and you can give us a call on 01277 525 020 or email a schedule or drawings to arrange it.

About our floor joint sealing in Sharpthorne

Sometimes the concrete either side of a joint has already spalled. A filler laid against broken edges has nothing sound to grip, so we’ll tell you if the joint edges need repairing first and explain how it affects the programme. We work on forklift and pallet-truck routes, construction joints and joints along racking aisles, and what we’re called in for most is brittle joint filler breaking up and untidy open joints in a retail unit. Whoever orders the work in Sharpthorne, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

In and around smaller places like Sharpthorne, 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.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Why act early in Sharpthorne

Duct tape or a general builders’ sealant can seem to buy some time. None of it is designed for wheel loads, and it typically ends up dragged across the floor. The right filler or sealant saves doing it twice. Halls, stores and units around places like Sharpthorne may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Why us?

  • Clear, fixed quotes
  • Failed material removed, not covered up

Floor joint sealing in Sharpthorne: the local picture

Sharpthorne is in the South East, one of the UK’s drier regions. Even so, yard and car park joints are only sealed when they’re dry and clean, and winter de-icing salt on car parks and ramps works into any open joint. Less than 3 miles from Sharpthorne there are at least three named estates and business parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

Phasing is what makes joint work possible on busy sites such as Horsted Keynes Business Park (2 miles south of Sharpthorne): one bay, aisle or car park row at a time. Schools like West Hoathly CofE Primary School often have long brick elevations with movement joints that age quietly.

Sharpthorne is about 4 miles south of East Grinstead, in West Sussex. Looking for floor joint sealing in Sharpthorne? We can help, as we do across West Sussex. Our West Sussex coverage takes in 373 places, large and small. Our Brighton page has more on work in that area (17 miles or so).

What the job involves on each surface

Construction joints

Day joints sit where one section of slab was cast against another. They often see more movement than sawn joints and that shapes the choice of filler or sealant.

Saw-cut induced joints

Induced joints are sawn into a new slab to control where it cracks. They start narrow and widen as the concrete dries so trafficked runs need a filler that holds the arrises.

Doing it in-house

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

What sets the cost

These are the things that shape the price:

  • Working within restricted access windows
  • The product specified
  • How accessible the joints are
  • Joint width, depth and condition

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Details that help us quote

The more we know, the firmer the quote. Helpful details to send:

  • Whether an asbestos survey exists
  • Photos of the joints, close up and from further back
  • Approximate linear metres or a joint schedule
  • Specification clauses that apply

Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings you can plan around. For a chat about it beforehand, give us a call on 01277 525 020 or email drawings and photos.

Diagnose, treat, sign off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Sharpthorne may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  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. We fill the joints with the agreed product, finished level.
  5. You get a time for each zone to reopen.

Preparing the site

  • Tell us your opening times and when work is allowed
  • Clear stock, furniture or equipment away from the joints
  • Arrange parking or a loading space

Common problems we fix in Sharpthorne

Left open, joints fill with grit, wrap and wood fragments. That debris is hard and levers at the edges as wheels pass, speeding up the damage.

Any of the following is a good reason to get the joints checked over:

  • Grimy joint lines spoiling a showroom floor
  • Brittle joint filler breaking up
  • Filler that has parted from one face
  • Loading bay joints breaking down

On a site such as Hangdown Mead Business Park, less than half a mile south-east of Sharpthorne, the movement joints are in car park slabs, paving and building elevations.
