Floor joint sealing for commercial buildings in Clanfield

Few warehouses can shut a whole floor while joints are done, so the work is split into zones and treated one area at a time. Share your site hours and access windows and the programme is built around them, with goods still moving in the areas we aren’t in. We work on construction joints, loading bays and joints along racking aisles, and the usual reasons a site gets in touch are dock area joints that have failed first and chipped and spalling edges along forklift routes. Whether you call it commercial sealant work, mastic application or joint sealing, in Clanfield it comes down to the same thing: the right product in a properly prepared joint.

Halls, schools and small commercial buildings near places like Clanfield have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.

A 12-month guarantee applies to all our work in Hampshire. If an installation problem shows up, ring 01277 525 020 or email the details over and we’ll arrange a return visit.

Cost factors for floor joints

These are the things that shape the price:

  • How accessible the joints are
  • Site requirements such as inductions and permits
  • Whether old sealant has to be cut out first
  • The total length or number of joints

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.

What to include in your enquiry

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

  • The site address and postcode
  • Drawings or a marked-up plan, if available
  • Whether the building will be occupied during the work
  • Whether an asbestos survey exists

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, give us a call on 01277 525 020 or send photos by email.

On site: what to expect

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For a building around Clanfield, 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. First, the zones and order of work are agreed with you.
  2. Any joints with broken edges are flagged before work starts.
  3. We clear each run back to clean concrete.
  4. The chosen filler or sealant goes in flush with the slab.
  5. You get a time for each zone to reopen.

What we need from you

  • Have the specification and drawings to hand
  • Send asbestos survey details if the building is pre-2000
  • Warn occupants and staff about the work

When to call us in Clanfield

Oil, laitance, dust and old cleaning chemicals build up inside joints. If the faces aren’t taken back to clean concrete first the new filler can’t stay bonded.

Site and facilities staff are often the first to spot these:

  • Filler that has parted from one face
  • Soft sealant dragged out of trafficked joints
  • A rough ride across broken joints
  • Dock area joints that have failed first

On a site such as Enterprise Industrial Estate, which lies south of Clanfield, the movement joints are in car park slabs, paving and building elevations.

What to look for in a quote

  • Do they follow the manufacturer’s priming guidance?
  • Whether their applicators hold CSCS cards
  • What level of public liability insurance do they hold?
  • Their approach to joint depth and backing

Our contractor checklist

General trades versus a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Looking after the joints

Keep the joints in good shape with a few simple steps:

  • Make joint checks part of your floor inspections
  • Keep trucks off new joints until we say they’re ready
  • Allow for topping up joints as a new slab settles
  • Start with the dock areas, where joints fail soonest

Young concrete carries on shrinking, so some fillers part slightly from one face. It is a known trait of new floors and a later top-up deals with it in the majority of cases.

Treating joints while the arrises are sound keeps the work simple. Once they have broken away, edge repair comes first and that takes longer and closes areas for longer.

FAQs: Clanfield

Do you take on work at healthcare sites like Petersfield Community Hospital?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is Clanfield too small for you to travel to?

No. Places such as Clanfield are covered as much as the big towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

Is it normal for joint filler to separate?

Young concrete carries on shrinking for a long time and a stiff filler can separate down one side. It is usually dealt with by topping up.

Are you CHAS accredited?

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

Do you have public liability insurance?

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

When it isn’t the sealant

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • A failing floor coating, which is a flooring contractor’s job
  • A floor that rocks at the joints, which needs a structural fix
  • A floor that is out of level for the racking or trucks

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.

What we seal

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