How we handle floor joint sealing in Sand Hill

Not every floor joint we treat is in a warehouse. Retail units, showrooms and trade counters have slab joints crossed by trolleys, footfall and cleaning machines, where a gappy, dirty joint looks untidy and snags castors. A neat, flush fill makes the floor easier to clean and look after. If you have unfilled floor joints collecting dirt and grit and joint edges breaking up under truck wheels, we can put it right. One point of contact handles commercial sealant work in Sand Hill from the first photographs to the final walk-round, whether it’s one building or several.

Smaller community and commercial buildings around Sand Hill have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Traffic, movement and joints around Sand Hill

Sand Hill lies roughly 40 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London, and their floor joints take forklift and pallet-truck traffic all day. 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 where de-icing salt is spread in winter, open joints let it in.

Hospital campuses such as Braintree Community Hospital, 4.7 miles south of Sand Hill, grow in stages, leaving movement joints wherever new blocks meet old.

Sand Hill is about 5 miles north-west of Braintree, in Essex. Commercial clients in Sand Hill can call on us for floor joints, as part of our coverage of Essex. We work across 644 places in Essex, large and small. Our London page has more on work in that area.

Doing it in-house

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.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

What sealant work can’t fix

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Spalled arrises, which need an edge repair first
  • A floor that rocks at the joints, which needs a structural fix
  • Structural cracking in the slab

If you’re not sure, just call the office on 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.

Your questions answered

Is Sand Hill too far out for you?

No. Places such as Sand Hill are covered as much as the big towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Do we have to stop operations in Sand Hill while the joints are sealed?

Typically not: we work in sections and hand each one back once it has cured. We agree the sequence and timings with you before we start.

How long does a job like this take?

We plan the time on site around your programme and access. You’ll have an expected duration with the quote.

Why is there a gap next to the joint filler?

Separation usually comes from slab shrinkage, poor preparation or the wrong product. We look at which it is before recommending anything.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.

What about RAMS and site documents?

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

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

On site: what to expect

Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Smaller jobs around Sand Hill can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. We walk the floor and mark up joint widths, edge damage and traffic routes.
  2. You receive a fixed quote showing products and phasing.
  3. Old fill and packed debris come out until both faces are sound.
  4. We extract the dust and prime the faces if the product needs it.
  5. Filler or sealant is placed to depth and finished flush.
  6. Zones reopen once cured and the work moves on.

Before we start on site

  • Have the specification and drawings to hand
  • Point out parking and an unloading spot
  • Make sure the joints can be reached

Loading bays and dock areas

Bays can be treated one or two at a time so deliveries keep moving. Tell us your site hours and access windows and we’ll plan around them.

Semi-rigid joint fillers

For trafficked warehouse joints, semi-rigid fillers are common. They are installed to the depth the manufacturer specifies and finished flush.

Leave it or put it right?

A floor coating laid over open joints soon cracks along the joint lines. The joints have to be filled or sealed as joints, whether or not the floor is coated. Around Sand Hill, it’s better to renew all the failing joints at once. Send photographs of each area and we will quote for the lot.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

What you get with us

  • Joints cleaned back to sound surfaces
  • Sealing commercial buildings since 2005
  • Workmanship guaranteed for 12 months
  • Public liability insurance in place

When to call us in Sand Hill

Older fills harden, shrink and crack with age especially under daily scrubbing and traffic. At that point it neither holds the edges nor keeps debris out.

Clients usually get in touch after noticing something like this:

  • Brittle joint filler breaking up
  • Joint fill separating from the concrete
  • Open saw cuts full of debris
  • Grimy joint lines spoiling a showroom floor

Around Sand Hill, each joint gets a filler or sealant matched to what crosses it and how much it moves.

What to look for in a quote

  • Their approach to joint depth and backing
  • Proof of insurance
  • Which product they’ll use, and why it suits the joint
  • Can the work be phased to keep areas open?
