Floor joint sealing across Sherborne St John

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

What the job involves on each surface

Loading bays and dock areas

We normally work through dock areas a few bays at a time so goods in and out carry on. Your site hours and access windows set the order.

Saw-cut induced joints

Most of the joints in a warehouse floor are saw cuts. We clear them back to clean concrete and fill them to the depth the product calls for, finishing flush with the slab.

Floor joint sealing for commercial buildings in Sherborne St John

A working floor can rarely be closed for days on end, so the work is split into zones and treated one area at a time. Tell us your site hours and access windows and we will plan around them, with goods still moving in the areas we aren’t in. Site teams most often ask us about open saw cuts full of debris and trucks and loads jolting over damaged joints, on loading bays, retail and showroom floors and forklift and pallet-truck routes. A specialist sealant contractor works differently from a general builder: on jobs in Sherborne St John, preparation and product choice get the time they need.

For a site near Sherborne St John, measurements and photos up front mean one trip where possible. Tell us the joint widths if you can, and what drives or walks over them.

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

Diagnose, treat, sign off

At the end of each section, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. Rural sites near Sherborne St John may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. We look at joint widths, edge condition and the traffic on each route.
  2. You get a fixed quote with the product and the phasing set out.
  3. Old filler, debris and contamination are cut or routed out back to clean concrete.
  4. Dust is sucked out of the joint and a primer used if the product data sheet asks for one.
  5. The chosen product is placed to its specified depth and trimmed level with the floor.
  6. The area is handed back once it has cured enough to take traffic.

Getting the site ready

  • Send any specification or drawings in advance
  • Clear stock, furniture or equipment away from the joints
  • Tell us what induction or permit system the site runs

Request a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

Advice

When something else is needed

Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:

  • Joint edges that have already broken away, which need repairing before filling (we will tell you if so)
  • Level or flatness problems across the floor
  • Unstable slabs moving under traffic

If you are not sure, just speak to us on 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

Your questions answered

Is Sherborne St John too far out for you?

Not at all. Sherborne St John is within our area. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

Is Knight Trade Park, near Sherborne St John, within your area?

Yes. We cover Sherborne St John and the area around it, including industrial estates, business parks and retail parks such as Knight Trade Park. A few photos and the unit address let us price the work.

Do you hold CHAS accreditation?

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

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Will we need to close the floor?

The work is phased. Areas are taken out of use a section at a time around the site hours and access windows you give us.

Which is better for warehouse joints, filler or sealant?

The answer comes from the traffic and the joint’s movement. Trafficked joints on truck routes typically need a semi-rigid filler to support the edges and joints with more movement take a flexible sealant.

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.

What we’re called out for in Sherborne St John

Pallet-truck and forklift wheels concentrate weight on a tiny contact patch. Where a joint is open, the wheel dips and strikes the far edge, and repeated impacts break the concrete away.

It’s worth sending us details if you spot any of the following:

  • Flexible sealant torn out by wheels
  • Cracked and crumbling joint fill
  • Dock area joints that have failed first
  • Broken arrises where pallet trucks cross

Phasing is what makes joint work possible on busy sites such as Devonshire Business Park (1.6 miles south of Sherborne St John): one bay, aisle or car park row at a time.

Questions to ask before you book

  • Will CSCS-carded applicators be on site?
  • Do they follow the manufacturer’s priming guidance?
  • What the guarantee covers, and for how long
  • Proof of insurance

Our contractor checklist

Cost factors for floor joints

Quotes vary with the job. It mainly depends on:

  • Whether the work must be split into stages
  • How accessible the joints are
  • Location, for remote and island sites
  • How much existing material needs removing

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Sending details for a quote

Diagnosis starts before we arrive. Let us know:

  • Your programme or deadline
  • The product your specification calls for
  • The postcode of the building
  • The asbestos register, for older buildings

To get a fixed quote, call 01277 525 020 or send details through our quote form with the site address and an outline of the work. Our quote form is another easy route.

Site staff or a sealant specialist?

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
