Floor joint sealing across Newington Butts

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

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, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Planning a London job such as one in Newington Butts starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we will schedule to suit.

  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. We hand each phase back when it can take traffic.

Before we start on site

  • Point out parking and an unloading spot
  • Confirm the product named in the specification
  • Send asbestos survey details if the building is pre-2000

How we handle floor joint sealing in Newington Butts

It isn’t only heavy industry. Retail units, showrooms and trade counters have slab joints crossed by trolleys, footfall and cleaning machines, and an open, grimy joint line looks poor as well as catching wheels. A neat, flush fill makes the floor easier to clean and look after. If you are dealing with joint edges breaking up under truck wheels and joint fill separating from the concrete, we can help, whatever the surface. Most enquiries from Newington Butts 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.

Most London buildings can’t shut a car park, loading bay or warehouse floor for long. We work through joints a section at a time, closing small areas in turn, at times agreed with the building manager.

Our workmanship is guaranteed for 12 months, in Newington Butts as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Why it’s worth doing now in Newington Butts

Tape, or whatever sealant is in the stores cupboard, may look like a fix for a while. None of it is designed for wheel loads and traffic soon pulls it out. A product chosen for the traffic and movement does the job once. In a London building, a failed joint rarely affects only one party. Dealing with it early is simpler for everyone.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

What you get with us

  • One phone line for London, the South East and Scotland
  • Old sealant cut out, never sealed over
  • 12 months’ guarantee on every job
  • Fully insured

Different surfaces, different methods

Retail and showroom floors

Polished and coated concrete floors in shops and showrooms show every joint. A flush, neat fill in a suitable colour keeps the floor looking right, and we will confirm the colours available for the specified product.

Semi-rigid joint fillers

If a joint is still opening, a semi-rigid filler may part from one face. That is normally dealt with by topping up later and we’ll flag it at quote stage.

Site staff or a sealant specialist?

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

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.

Your questions answered

Is a hospital such as Evelina London Children's Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Can you work at a site such as Southwark Bridge Business Centre, by Newington Butts?

Yes. Our area takes in Newington Butts and its surroundings, with estates and business parks such as Southwark Bridge Business Centre included. To start, just speak to us on 01277 525 020 or email us with the unit, the joints involved and your access times.

Is the floor joint work guaranteed?

A 12-month guarantee covers the work we do. It applies to our workmanship rather than structural movement or accidental damage.

Do you repair broken joint edges?

Filling against broken edges doesn’t last. We will tell you if the joint edges need repairing first, so you can decide how to proceed.

When can forklifts run over new joint filler?

Each product has its own cure time, and cold floors slow it down. We plan the phasing so that waiting time fits your operation.

How do we get a quote for floor joints?

A rough joint length, a few photographs and a site plan are typically enough for a quick quote. For larger floors, a site visit is often best, and you can call 01277 525 020 or send photos by email to arrange it.

Is Newington Butts in your area?

Yes. We take on work across Newington Butts.

Cost factors for floor joints

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

  • Access and working height
  • Whether the work must be split into stages
  • Which sealant the job calls for
  • The total length or number of joints

What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a quote once you have the details.

Sending details for a quote

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • A wide shot and a close-up of the area
  • Any dates the work must fit around
  • Anything awkward about access or site hours
  • The site address and postcode

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, call 01277 525 020 or email the details over.

What sealant work can’t fix

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:

  • Broken concrete either side of the joint
  • A floor that rocks at the joints, which needs a structural fix
  • Worn screed or surface finishes

Not sure which it is? You can ring 01277 525 020 or email us and we’ll tell you honestly before you book.
