Floor joint sealing for businesses in Upper Swanmore

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

Our process

Site rules come first: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact. For a building around Upper Swanmore, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. A floor survey records every joint, its edges and what crosses it.
  2. The treatment and the zones are set out in a fixed quote.
  3. Each joint is cut or routed back to clean, sound concrete.
  4. Dust is vacuumed out and primer applied where specified.
  5. Filler or sealant is placed to depth and finished flush.
  6. We hand each phase back when it can take traffic.

What we need from you

  • Share the asbestos register for older buildings
  • Confirm the product named in the specification
  • Flag any permit to work we will need

Ask for a quote

Every quote starts with the facts: 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.

How we handle floor joint sealing in Upper Swanmore

Few warehouses can shut a whole floor while joints are done, so we phase the work aisle by aisle or bay by bay. Share your site hours and access windows and the programme is built around them so the rest of the operation keeps going. We work on loading bays, construction joints and retail and showroom floors, and the failures we are asked to look at most are joint fill separating from the concrete and untidy open joints in a retail unit. One point of contact handles commercial sealant work in Upper Swanmore from the first photographs to the final walk-round, whether it’s one building or several.

For a site near Upper Swanmore, measurements and photographs up front mean one trip where possible, with the right materials on hand. Note joint widths and the traffic that uses them, and we’ll take it from there.

The 12-month guarantee is for workmanship rather than 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.

Owners, agents and contractors

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

How the job changes by surface

Retail and showroom floors

We plan shop-floor work so trading can continue. Tell us your site hours and access windows and we’ll plan around them.

Construction joints

Day joints sit where one section of slab was cast against another. They can move more than saw cuts, and that shapes the product choice.

When something else is needed

We check first that sealant really is the fix. It isn’t the answer for:

  • Damaged or worn floor coatings and screeds
  • Joint edges that have already broken away, which need repairing before filling (we’ll tell you if so)
  • Wide or random cracking that suggests a structural issue

If you are not sure, just give us a call on 01277 525 020 or use the quote form and we’ll give you a straight answer.

What we seal

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

FAQs: Upper Swanmore

Do you take on work at healthcare sites like Knowle Hospital?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is Upper Swanmore off your patch?

Not at all. Upper Swanmore is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Which sealant will you use?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Do you guarantee industrial floor joints?

A 12-month guarantee covers the work we do. It covers our workmanship, not later slab movement or damage from impacts.

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and we’ll price the work to it.

How long does a job like this take?

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

When to call us in Upper Swanmore

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.

Look out for the following:

  • Sealant pulled out along a truck route
  • Drivers complaining about joints on a route
  • Dock area joints that have failed first
  • Grimy joint lines spoiling a showroom floor

Another example is Waltham Business Park, 1.3 miles to the south-west of Upper Swanmore, where floors and yards would be done in stages around the occupiers.

What to look for in a quote

  • How the existing material will be dealt with
  • What site paperwork they can supply
  • Which product they’ll use, and why it suits the joint
  • Their public liability cover

Joints that move: notes for Upper Swanmore

Upper Swanmore is in the South East, one of the UK’s drier regions. External slab and deck joints still need a dry, clean joint to seal, and gritting in cold spells finds its way into open joints. Upper Swanmore is about 60 miles from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital, and their floor joints take forklift and pallet-truck traffic all day.

Schools such as Swanmore Church of England Aided Primary School have movement joints in their walls and floors that are easy to overlook. Parks like Swanmore Business Park (to the south-west of Upper Swanmore) combine paved areas, car parks and building elevations, each with joints that move.

Upper Swanmore is about 6 miles north-east of Hedge End, in Hampshire. Commercial clients in Upper Swanmore use us for work on floor joints. Our Hampshire coverage takes in 723 places, large and small. Our Southampton page has more on work in that area, about 10 miles away.

After the work

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Stop forks and pallets being dragged across joints
  • Keep trucks off new joints until we say they’re ready
  • Clear packed debris from open joints regularly
  • Expect fillers on young slabs to need a top-up

Normal floor cleaning is fine once the product has cured. If you use strong chemicals or hot-water washing, mention it when we quote so the product suits them.

A broken joint on a main route is crossed by every truck on that route. Sorting it early looks after your equipment as well as the slab.
