Floor joint sealing near Langley Green

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Our process

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Several jobs near Langley Green can be grouped on one trip. Tell us your site hours and we will plan around them.

  1. A floor survey records every joint, its edges and what crosses it.
  2. You receive a fixed quote showing products and phasing.
  3. Old fill and packed debris come out until both faces are sound.
  4. Dust is vacuumed out and primer applied where specified.
  5. The joint is filled to its specified depth and trimmed level.
  6. Zones reopen once cured and the work moves on.

What we need from you

  • Let building users know which areas are affected
  • Move anything stored against the joints
  • Have the specification and drawings to hand

Advice

About our floor joint sealing in Langley Green

Across Langley Green and the rest of West Sussex, it runs the same way: you send details, we send a fixed quote, the joints are done and the 12-month guarantee follows. Approximate joint lengths, a few photos and a floor plan are enough for a quick quote and a visit can be arranged where that is easier. The enquiries we see most involve open saw cuts full of debris and failing joints at loading bays and dock doors, on loading bays, joints along racking aisles and forklift and pallet-truck routes. For commercial sealant work in Langley Green, you deal with one contact from quote to sign-off, whether it’s one building or several.

Small units near places like Langley Green are often converted farm buildings with new concrete floors. Saw-cut and construction joints in those floors need the right filler or sealant for the forklifts and trolleys that use them.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Slabs, ramps and loading bays in Langley Green

Langley Green sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, and winter de-icing salt on car parks and ramps works into any open joint. Crawley, one of the planned towns of the twentieth century, takes in or adjoins Langley Green. Industrial estates in planned towns were built in phases, so whole rows of units can need their floor joints done at once.

For a school such as Langley Green Primary, playground and building joints can be done in the holidays. Large sites such as Langley Green Hospital (psychiatric) (to the east of Langley Green) have car parks, service roads and long elevations with movement joints in brick and panels. Another example is County Oak Retail Park, which lies north-east of Langley Green, where floors and yards would be done in stages around the occupiers.

Langley Green is about 1 mile north of Crawley, in West Sussex. Any commercial site in Langley Green is covered, whether it’s a single job or part of a planned programme. Langley Green is one of 373 places in West Sussex on our list for floor joints. For work in that direction, see our Brighton page.

Work on floor joints is covered throughout RH11 and RH10. Buildings on London Road, Cherry Lane and Dobson Road are within our area. We also cover West Green (1 mile south), Crawley (1 mile south), Three Bridges (2 miles south-east), Southgate (2 miles south) and Forge Wood (2 miles east). Nearby towns on our patch include Horsham (7 miles south-west), Haywards Heath (10 miles south-east), Burgess Hill (12 miles south), East Grinstead (8 miles east), Broadfield (3 miles south) and Billingshurst (14 miles south-west).

Questions we are asked in Langley Green

Do you cover business parks and estates near Langley Green, such as Basepoint Business Centre?

Yes. We cover Langley Green and the area around it, including industrial estates, business parks and retail parks such as Basepoint Business Centre. Photos and a short description are enough for a first look.

Can you take on a job at a hospital such as Langley Green Hospital (psychiatric)?

Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Do you repair broken joint edges?

Filling against broken edges doesn’t last. We will tell you if the joint edges need repairing first and set out how that affects the job.

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

It depends on the traffic and the movement. Trafficked joints on truck routes normally need a semi-rigid filler to support the edges and joints with more movement take a flexible sealant.

Commercial clients in Langley Green

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Langley Green can form part of a wider programme across West Sussex.

Doing it in-house

General builders and handymen seal joints, but it isn’t their main trade. 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 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.

How the quote is worked out

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

  • How much there is to seal
  • Access and working height
  • The product specified
  • Phasing around occupants

What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a fixed quote when you are ready.

Details that help us quote

For an accurate fixed quote, we need a clear picture of the site. Send us:

  • What the building is and how it’s used
  • The site address and postcode
  • Anything awkward about access or site hours
  • Clear photos of the problem areas

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, call 01277 525 020 or use the quote form.

After the work

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Tell us about strong cleaning chemicals before we quote
  • Sweep debris out of open joints until they can be filled
  • Treat loading bay joints first if they’re failing
  • Record damaged joints with a photo and a location

If a joint we filled starts to break up within 12 months, tell us and we will arrange a look. Beyond that, an inspection once or twice a year catches failing joints early.

A broken joint on a main route is crossed by every truck on that route. Sorting it early looks after your equipment as well as the slab.

Leave it or put it right?

While the arrises are intact, filling a joint is straightforward. Wait until the edges have spalled and the concrete needs repairing before the joint can be filled which means more downtime in that zone. In a smaller place such as Langley Green, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
