Floor joint sealing near River

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Floor joint sealing in River

Concrete floors in warehouses and factories are cut into bays by saw-cut joints and construction joints, and every one of those joints is an exposed edge under hard wheels. Our job is to put the right filler or sealant into them for the loads and the movement they see, so the arrises are supported and grit stays out. Site teams most often ask us about a rough ride across broken joints and grimy joint lines spoiling a showroom floor, on retail and showroom floors, saw-cut induced joints and loading bays. Most enquiries from River start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

In and around smaller places like River, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

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.

What sealant work can’t fix

We check first that sealant really is the fix. It won’t put right:

  • Level or flatness problems across the floor
  • Cracks across panels caused by settlement or overload
  • A floor that rocks at the joints, which needs a structural fix

If you’re not sure, just speak to us on 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.

What we seal

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

Common questions from River clients

Do you cover business parks and estates near River, such as Hampers Common Industrial Estate?

Yes. We cover River and the area around it, including industrial estates, business parks and retail parks such as Hampers Common Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.

Is River too small for you to travel to?

No. Places such as River 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 will plan the job to need as few trips as possible.

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

How long does a typical visit take?

The duration is planned around your programme and the access we’re given. We will give you an estimate of time on site when we quote.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

Are you fully insured?

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

What guarantee do you give on joint filling?

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

Quoting for work in River

A fixed quote reflects the actual work. It takes account of:

  • Whether the work must be split into stages
  • Specialist products, such as fire-rated or hygienic sealants
  • The total length or number of joints
  • Any access equipment needed

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

What we need to price the job

We can often quote from photos and a few details. It helps to include:

  • What the building is and how it’s used
  • Any dates the work must fit around
  • Access details, including height
  • Approximate linear metres or a joint schedule

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

General trades versus a specialist

Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

Slabs, ramps and loading bays in River

River lies roughly 42 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London; their floors carry heavy traffic every shift. Less than 3 miles from River there are two named estates and business parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.

If you manage units on an estate such as Hampers Common Industrial Estate, 2.4 miles to the east of River, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch. Large sites such as Midhurst Community Hospital, 3.2 miles west of River, have car parks, service roads and long elevations with movement joints in brick and panels.

What we’re called out for in River

An ageing filler or sealant can go brittle and split especially under daily scrubbing and traffic. Once it has gone hard or come loose, it protects nothing.

Most enquiries start with one or more of the following:

  • Chipped and spalling edges along forklift routes
  • Loading bay joints breaking down
  • Filler that has parted from one face
  • A rough ride across broken joints

Another example is Colhook Industrial Park. (2.5 miles north-east of River), where floors and yards would be done in stages around the occupiers.

Questions to ask before you book

  • Which product they’ll use, and why it suits the joint
  • The terms of the workmanship guarantee
  • Whether old or failed sealant will be cut out, not overlaid
  • Proof of insurance

Questions to ask before you appoint anyone

Why it’s worth doing now in River

A floor coating laid over open joints soon cracks along the joint lines. The joints have to be filled or sealed as joints before or alongside any coating work. Halls, stores and units around places like River may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.
