Floor joint sealing across Chartway Street

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

From enquiry to sign-off

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work typically takes anything from a day for one loading bay to several days for a large floor, split into phases. Jobs in and around smaller places like Chartway Street are normally planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  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. Each joint is cleared of old fill and dirt and taken back to clean, sound edges.
  4. Dust is sucked out of the joint and a primer used if the product data sheet asks for one.
  5. We fill each joint to depth and finish it flush so wheels roll straight across.
  6. We tell you when each zone can carry trucks again and move on to the next.

What we need from you

  • Tell us what induction or permit system the site runs
  • Agree which areas must stay open
  • Have the specification and drawings to hand

Getting a fixed quote

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Cost factors for floor joints

These are the things that shape the price:

  • The site’s rules and procedures
  • Travel to remote or island sites
  • Quantities, in metres or numbers
  • Specialist products, such as fire-rated or hygienic sealants

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

What to include in your enquiry

Good information means a firmer quote. When you get in touch, include:

  • Anything awkward about access or site hours
  • The postcode of the building
  • Photos of the joints, close up and from further back
  • When you need the work done

The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or phone 01277 525 020 or email drawings and photos to discuss it first.

For managing agents and facilities managers

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Chartway Street. One quote can cover more than one site, which keeps the paperwork simple.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

When to bring in a specialist

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.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Slabs, ramps and loading bays in Chartway Street

Chartway Street is in the South East, one of the UK’s drier regions. 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. Less than 3 miles from Chartway Street there are at least three named estates and business parks. Their warehouses, yards and car parks are exactly where joints take the most punishment.

In a school such as Kingswood Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. Another example is Orchard Industrial Estate (2.6 miles west of Chartway Street), where floors and yards would be done in stages around the occupiers. Estates like Park Wood Trading Estate, 2.5 miles north-west of Chartway Street, combine warehouse slabs, yards and loading bays, all with joints under wheels.

Why act early in Chartway Street

Dirt and spillage gather in open joints, out of reach of the floor cleaner. Where the floor is on show or needs to be kept clean, that is a problem. Flush, filled joints leave nothing for cleaners to dig out. Around Chartway Street, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we’ll quote for the lot.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

What the job involves on each surface

Loading bays and dock areas

Loading bays combine the heaviest turning loads with wet tyres and cold air from open doors. Joints here typically fail first so many programmes begin here.

Saw-cut induced joints

Most of the joints in a warehouse floor are saw cuts. Each one is cleaned out and filled to the specified depth, finishing flush with the slab.

Questions about Chartway Street

Will you take on work at estates like Park Wood Trading Estate, close to Chartway Street?

Yes. Estates, retail parks and business parks around Chartway Street, Park Wood Trading Estate among them, are all within reach. Photos and a short description are enough for a first look.

Do you take on work at healthcare sites like KIMS hospital?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Who decides which product is used?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Why has the filler pulled away from one side?

It can be shrinkage, contamination on the joint faces or a product unsuited to the movement. We diagnose the cause before suggesting a fix.

Is the floor joint work guaranteed?

Every job has our 12-month guarantee. It covers our workmanship, not later slab movement or damage from impacts.

Do you seal on top of existing sealant?

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

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
