Floor joint sealing for businesses in Compton

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

For managing agents and facilities managers

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Compton. One quote can cover more than one site, so there’s one set of paperwork to deal with.

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first.

How we handle floor joint sealing in Compton

Forklifts and pallet trucks are hard on open joints. Every pass chips at the bare concrete edge until a crisp saw cut becomes a wide, broken groove. A properly filled joint carries the wheel over and protects both arrises. It also smooths the route for drivers and stock. If you have broken arrises where pallet trucks cross and failing joints at loading bays and dock doors, we can put it right. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Compton, that means joint design, primers and backing rod as standard.

In and around smaller places like Compton, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Site staff or a sealant 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 normally costs more in the end than doing them right.

Your questions answered

Is Compton too far out for you?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Can you work on a hospital site such as Wessex Hospital?

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

Can the sealant be colour-matched?

That depends on the product. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.

How long will the new sealant last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Do you hold CHAS accreditation?

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

How long before trucks can use the joints?

Each product has its own cure time and cooler floors take longer. We plan the phasing so that waiting time fits your operation.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Diagnose, treat, sign off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. If others near Compton need work, visits can be combined. You will have a fixed quote before work starts.

  1. We walk the floor and mark up joint widths, edge damage and traffic routes.
  2. The treatment and the zones are set out in a fixed quote.
  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. The joint is filled to its specified depth and trimmed level.
  6. Zones reopen once cured and the work moves on.

Quoting for work in Compton

Quotes vary with the job. Expect it to depend on:

  • Site requirements such as inductions and permits
  • Travel to remote or island sites
  • The product specified
  • The size and state of each joint

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.

Sending details for a quote

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

  • Where the site is, with the postcode
  • Approximate linear metres or a joint schedule
  • Anything awkward about access or site hours
  • The type of building and who uses it

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.

What the job involves on each surface

Semi-rigid joint fillers

A semi-rigid fill can separate along one side while a slab is still shrinking. A later top-up usually puts that right and we’ll flag it at quote stage.

Saw-cut induced joints

A sawn joint left open soon packs with debris and chips at the edges. Filled in good time, they stay narrow and neat.

Traffic, movement and joints around Compton

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. At about 63 miles from central London, Compton is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital; their floors carry heavy traffic every shift.

Phasing is what makes joint work possible on busy sites such as Wessex Business Park (2.4 miles south-east of Compton): one bay, aisle or car park row at a time. For buildings at a park such as Hazeley Enterprise Park (1.4 miles east of Compton), brick and panel movement joints are easy to forget until one leaks. For estates staff at a university like University of Winchester, 2.7 miles north of Compton, building and paving joints are part of the planned maintenance list.

Compton is about 3 miles south of Winchester, in Hampshire. Anywhere in SO21, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 723 places in Hampshire. Southampton is covered too, some 8 miles away.

We take on floor joints across the SO21 postcode area, whatever the building. Streets here include Field Way, Clease Way and Cliff Way. Just outside Compton, we also work in South Down (1 mile south), Shawford (1 mile east), Otterbourne (1 mile south), Twyford (1 mile east) and Oliver's Battery (2 miles north). Nearby towns on our patch include Winchester (3 miles north), Eastleigh (4 miles south), Fareham (13 miles south-east), Andover (14 miles north-west), Totton (10 miles south-west) and Chandler's Ford (3 miles south-west).

Near you in Compton

We work on buildings around The Bridge Inn, Thornden School and St. Cross Park. The closest station to Compton is Shawford station, roughly 0.5 miles east of the centre. Other landmarks nearby include Balfour Museum of Hampshire Red Cross History (2.4 miles north) and Royal Hampshire County Hospital (2.8 miles north). Green spaces nearby include Shawford Down and Twyford Down.

Maintenance after handover

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Expect fillers on young slabs to need a top-up
  • Treat loading bay joints first if they’re failing
  • Keep photos of joints that look like they’re failing
  • Sweep debris out of open joints until they can be filled

Once cured, the joints get cleaned along with the slab. Tell us about aggressive cleaning products or hot washing at quote stage so we choose something that tolerates them.

While the concrete edges are intact, it’s a filling job. Once they have broken away, edge repair comes first, with more downtime and more disruption.
