Floor joint sealing in Crosswater, done properly

Across Crosswater and the rest of Surrey, it runs the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Approximate joint lengths, a few photographs and a floor plan are enough for a quick quote, or we can arrange a site visit. We work on loading bays, joints along racking aisles and forklift and pallet-truck routes, and the usual reasons a site gets in touch are cracked and crumbling joint fill and scruffy, dirty joint lines on a shop or showroom floor. Whoever orders the work in Crosswater, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

Around smaller places such as Crosswater, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Site staff or a sealant specialist?

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

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.

FAQs: Crosswater

Is Crosswater too far out for you?

No. Small places get the same service as large ones. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Can you take on a job at a hospital such as Chase Community Hospital?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

How do you choose the sealant?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

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.

How many days will you need on site?

That varies with the scale of the job, but the work normally 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 will set out a timescale with the quote.

Does the weather affect the work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

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

The answer comes from the traffic and the joint’s 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.

When to call us in Crosswater

A soft, flexible sealant on a forklift route can’t hold the arrises up, so the concrete still breaks beside it. The opposite mistake happens as well: a stiff filler in a joint that keeps moving splits or comes away from the sides.

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

  • Dock area joints that have failed first
  • Broken arrises where pallet trucks cross
  • Saw-cut joints left open and packed with grit
  • Untidy open joints in a retail unit

For a school such as St John's CofE Aided Infant School, playground and building joints can be done in the holidays.

Questions to ask before you appoint anyone

Slabs, ramps and loading bays in Crosswater

Crosswater is about 38 miles from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors, and their floor joints take forklift and pallet-truck traffic all day. Rainfall across the South East, Crosswater included, is lower than in many 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.

For estates staff at a university like University for the Creative Arts, 4.7 miles north of Crosswater, building and paving joints are part of the planned maintenance list. Sites like Chase Community Hospital, 4.7 miles to the south-west of Crosswater, carry ambulances, deliveries and visitors’ cars over their road and deck joints.

How the quote is worked out

The price varies from site to site. Expect it to depend on:

  • Phasing around occupants
  • Travel to remote or island sites
  • How much existing material needs removing
  • The site’s rules and procedures

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Sending details for a quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • The asbestos register, for older buildings
  • Anything awkward about access or site hours
  • Any dates the work must fit around
  • The postcode of the building

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to ring 01277 525 020 or email a schedule or drawings with what you know.

Honest limits

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • A floor that rocks at the joints, which needs a structural fix
  • Structural cracking in the slab
  • Joint edges that have already broken away, which need repairing before filling (we will tell you if so)

If you’re not sure, just phone 01277 525 020 or send photos by email and we will give you a straight answer before you book.

Joints and surfaces we work on

  • Joints along racking aisles
  • Retail and showroom floors
  • Construction joints
  • Loading bays
  • Forklift and pallet-truck routes
  • Saw-cut induced joints

On site: what to expect

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself normally taking a day or more, depending on the metres of joint and how many zones the floor is split into. For work around Crosswater, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. First, the zones and order of work are agreed with you.
  2. We point out joints whose edges need repairing first.
  3. Failed material and debris are removed and the joint cleaned.
  4. The chosen filler or sealant goes in flush with the slab.
  5. You get a time for each zone to reopen.

Preparing the site

  • Share your working hours and any access restrictions
  • Flag any permit to work we will need
  • Point out parking and an unloading spot

Getting a fixed quote

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
