Expansion joint sealing for businesses in Matfield

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

Different surfaces, different methods

Internal floor movement joints

Wheeled traffic chips floor joint edges that aren’t supported. The right filler or sealant for the traffic and movement protects them.

Joints between different materials

Junctions between brick and render, or concrete and cladding, move independently. The product must bond to both substrates and cope with the movement.

How we handle expansion joint sealing in Matfield

We cover the full range of movement joints: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. Every one calls for a sealant picked for its movement, exposure and traffic. We work on precast concrete panel joints, blockwork control joints and brickwork movement joints, and the usual reasons a site gets in touch are arrises breaking up along floor joints and new sealant over old, now failing. Looking for mastic applicators who cover Matfield? Mastic Doctor has worked for contractors, FMs and building owners since 2005.

Smaller community and commercial buildings around Matfield have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.

Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

What happens if it’s left?

A like-for-like reseal of a joint that keeps splitting rarely lasts. A higher movement class, or a design change by the engineer, may be needed, and we’ll say so before quoting. Converted and older buildings near places like Matfield tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

Whether it’s a single area or a whole estate, the same things set the price: 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.

Floors, slabs and movement joints in Matfield

Central London is about 31 miles from Matfield. 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. Rainfall across the South East, Matfield included, is lower than in many parts of the UK. External joints still wait for dry conditions, and where de-icing salt is spread in winter, open joints let it in.

For an estate such as Tunbridge Wells Hospital at Pembury, which lies west of Matfield, the joints in ramps, decks and long building elevations all need attention over time. Schools such as Brenchley and Matfield Church of England Primary School have movement joints in their walls and floors that are easy to overlook. For an occupier at a site such as Eldon Way Industrial Estate, which lies north of Matfield, the joints at loading doors and dock levellers usually see the hardest wear.

Matfield is about 5 miles east of Royal Tunbridge Wells, in Kent. Anywhere in TN12, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 931 places in Kent, large and small. There’s a separate page for London, roughly 31 miles from Matfield.

Common questions from Matfield clients

Is a hospital such as Tunbridge Wells Hospital at Pembury somewhere you can work?

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.

Is Matfield too far out for you?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

Can staff carry on working while you are here?

In most cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

Can weather delay the job?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

What exactly is a movement joint?

The terms overlap a great deal. Both let materials grow and shrink with temperature, moisture and load, and the seal across it keeps water and debris out.

How do we ask for a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

What about RAMS and site documents?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Cost factors for movement joints

Before we quote, we look at:

  • The size and state of each joint
  • How much existing material needs removing
  • Site requirements such as inductions and permits
  • Quantities, in metres or numbers

There’s no price list, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

What to include in your enquiry

A few photographs plus some basic facts will normally do. It helps to include:

  • Clear photographs of the problem areas
  • Specification clauses that apply
  • Access details, including height
  • Approximate linear metres or a joint schedule

Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to ring 01277 525 020 or email the details over.

When it isn’t the sealant

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

  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Joints too narrow for the movement, which need redesigning by the engineer
  • Cracking or settlement that calls for an engineer’s assessment

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

Joints and surfaces we work on

  • Car park decks and ramps
  • Precast concrete panel joints
  • Brickwork movement joints
  • Blockwork control joints
  • Podiums and floor movement joints
  • Cladding panel joints

Diagnose, treat, sign off

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before the next one starts. If others near Matfield need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Finished joints are checked and backed by our 12-month guarantee.

What we need from you

  • Flag any permit to work we’ll need
  • Send any specification or drawings in advance
  • Tell us which areas need to stay in use

Getting a fixed quote

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or email a schedule or drawings.
