Your questions answered

Do you take on work at healthcare sites like Princess Royal Hospital?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Is a smaller place like Furner's Green outside your area?

No. Places such as Furner's Green are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Are you CHAS accredited?

Yes. We are CHAS accredited and a Constructionline member.

Do you reseal car park expansion joints?

Yes, we do. Tyre loads, grit and de-icing salts make these some of the hardest joints to keep sealed, and we will tell you if any edges need repairing first.

Can you work while the building is occupied?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

What sealant do you use in movement joints?

The specification comes first, then the joint’s movement and exposure. We name the proposed product in the quote, so you know what’s going in.

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Expansion joint sealing in Furner's Green

Brickwork and blockwork walls have vertical movement joints at intervals that most people only notice when the sealant has gone. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal comes out, backing goes in and a sealant with the right movement class is applied. If you are dealing with water getting into the wall through a failed joint and joints packed with grit and debris, we can help, whatever the surface. For commercial sealant work in Furner's Green, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

In and around smaller places like Furner's Green, 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.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

What sets the cost

Before we quote, we look at:

  • Whether old sealant has to be cut out first
  • Location, for remote and island sites
  • Joint width, depth and condition
  • The product specified

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

What to include in your enquiry

Diagnosis starts before we arrive. Tell us:

  • Whether the building will be occupied during the work
  • Photos of the joints, close up and from further back
  • Anything awkward about access or site hours
  • The product your specification calls for

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.

Common problems we fix in Furner's Green

Sun, rain and frost age external movement joints. In time the bead chalks, stiffens and cracks and opens at the next temperature swing.

If one of these sounds familiar, it’s time for a closer look:

  • Weathered movement joint sealant that no longer flexes
  • Joints packed with grit and debris
  • Joints where the bead has lost adhesion
  • New sealant over old, now failing

Business parks such as Horsted Keynes Business Park, 2.9 miles to the north-west of Furner's Green, have car parks, paved areas and long brick and panel elevations, all with movement joints.

Before you book anyone

  • What the guarantee covers, and for how long
  • Their public liability cover
  • Whether their applicators hold CSCS cards
  • Are they CHAS accredited or on Constructionline?

Questions to ask before you appoint anyone

Surface by surface

Cladding panel joints

We confirm what access is in place before pricing. Close-up photos help us judge the joints.

Podium joints

On podiums, the joint can belong to a larger waterproofing detail. Where the specification calls for sealant, we reseal, and tell you if the problem looks like the waterproofing below.

Why deal with it now?

Some quotes just add sealant over the old bead. A bead laid on top of the failed one neither grips nor flexes properly. We cut out the old seal and prepare the faces every time. Converted and older buildings near places like Furner's Green tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Doing it in-house

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Joints that move: notes for Furner's Green

Diagnose, treat, sign off

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work normally takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. If others near Furner's Green need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

  1. We assess the joints on site or from photos, noting widths and how each has failed.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Before we start on site

  • Clear stock, furniture or equipment away from the joints
  • Share the asbestos register for older buildings
  • Warn occupants and staff about the work
