Floor joint sealing near Cottonworth

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Maintenance after handover

After handover, these steps help:

  • Keep grit out of unfilled joints in the meantime
  • Ask drivers not to drag forks or pallets
  • Expect fillers on young slabs to need a top-up
  • Photograph any joint that starts to chip

Problems inside the 12-month guarantee period are ours to put right. After that, a check before your busiest period keeps small repairs small.

Joint damage starts slowly and then speeds up. Each chip makes the drop deeper and the next impact harder so early treatment saves a lot of trouble.

Floor joint sealing in Cottonworth

Before quoting, we look at what the floor is telling us: how wide the joints are, signs of ongoing movement, the wheel types crossing them and the state of the arrises. From that we choose between a semi-rigid filler and a more flexible sealant and the answer can differ from one zone to the next. We work on retail and showroom floors, saw-cut induced joints and construction joints, and what we’re called in for most is dock area joints that have failed first and joint fill separating from the concrete. A single leaking joint is often how a building in Cottonworth first comes to us: we look at the rest while we’re there and tell you what we find.

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

Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Commercial clients in Cottonworth

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.

Traffic, movement and joints around Cottonworth

The South East is one of the drier parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and gritting in cold spells finds its way into open joints. Cottonworth is about 63 miles from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors.

If you manage units on an estate such as Harewood Forest Industrial Estate, 2.9 miles north-east of Cottonworth, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch.

Signs you need floor joint sealing in Cottonworth

Oil, laitance, dust and old cleaning chemicals build up inside joints. Without cutting back to sound, clean concrete, the new material simply lifts out.

These are often picked up first by site or facilities staff:

  • Open saw cuts full of debris
  • Dock area joints that have failed first
  • Filler that has parted from one face
  • Grimy joint lines spoiling a showroom floor

Sites like Andover War Memorial Hospital, 4.4 miles to the north of Cottonworth, carry ambulances, deliveries and visitors’ cars over their road and deck joints.

What your quote should include

  • Whether old or failed sealant will be cut out, not overlaid
  • Will CSCS-carded applicators be on site?
  • The named product and why it was chosen
  • Their approach to joint depth and backing

Choosing a commercial sealant contractor

Our process

We bring the products specified for the job, along with primers and backing rod. 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. Jobs in and around smaller places like Cottonworth are typically planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  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. The chosen filler or sealant goes in flush with the slab.
  5. You get a time for each zone to reopen.

Before we start on site

  • Move anything stored against the joints
  • Tell us what induction or permit system the site runs
  • Agree which areas must stay open

Quotes

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Related advice

Cottonworth: questions and answers

Can you take on a job at a hospital such as Andover War Memorial Hospital?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is Cottonworth too small for you to travel to?

No. Places such as Cottonworth are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

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

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

What if there’s asbestos in the old mastic?

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

What site paperwork can you supply?

Each site asks for different documents, so tell us what you need and we will confirm it when we quote.

Do you repair broken joint edges?

We check the edges as part of the survey. Where they have broken away, we’ll tell you before quoting the filling, so nothing is filled that won’t hold.

Are you insured?

Yes. We’re fully insured, and the certificate can go with your quote.

What sets the cost

What shapes the price:

  • Which sealant the job calls for
  • Induction, permit and paperwork requirements
  • How much there is to seal
  • Working within restricted access windows

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.

What we need to price the job

A good diagnosis starts with the right details. Tell us:

  • Anything awkward about access or site hours
  • Whether the building will be occupied during the work
  • When you need the work done
  • The postcode of the building

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. To get it moving, give us a call on 01277 525 020 or email drawings and photos.

When to bring in a specialist

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

Redoing a failed joint usually costs more than getting it right at the outset, 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.
