Expansion joint sealing in Goathurst Common

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Expansion joint sealing for commercial buildings in Goathurst Common

Width, depth and product all have to work together. Joint width must suit the movement and the movement class of the sealant, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1. If you have joints packed with grit and debris and weathered movement joint sealant that no longer flexes, we can help. Most enquiries from Goathurst Common start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In and around smaller places like Goathurst Common, 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.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Traffic, movement and joints around Goathurst Common

Goathurst Common is in the South East, one of the UK’s drier regions. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints. At about 20 miles from central London, Goathurst Common is within reach of the capital. Warehousing clusters around the motorways that ring and radiate from London.

Hospitals like Sevenoaks Hospital (3.5 miles north-east of Goathurst Common) have multi-storey or surface car parks whose joints carry vehicles round the clock. Schools such as Ide Hill Church of England Primary School have movement joints in their walls and floors that are easy to overlook.

Goathurst Common is about 3 miles south-west of Sevenoaks, in Kent. Across the TN14 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee.

Signs you need expansion joint sealing in Goathurst Common

Sometimes the sealant holds but the substrate breaks away. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip, so we tell you if the edges need repairing first.

Look out for the following:

  • Chipped joint edges on forklift routes
  • Previous reseals laid over old sealant
  • Movement joints with split or torn sealant
  • Sealant pulling off the joint face

On a site such as Salters Heath Business Centre (1.9 miles north-east of Goathurst Common), the movement joints are in car park slabs, paving and building elevations.

Before you book anyone

  • The named product and why it was chosen
  • How the joint faces will be prepared and primed
  • What site paperwork they can supply
  • The terms of the workmanship guarantee

Questions to ask before you appoint anyone

Different surfaces, different methods

Car park decks and ramps

Water coming through deck joints is the usual first sign. The old seal comes out, the edges are prepared and the joint resealed.

Cladding panel joints

Metal and composite panels shift considerably as temperatures change. The joints need a low-modulus sealant with enough movement capability in a colour confirmed for that product.

Why act early in Goathurst Common

Re-sealing with the same product that failed is often a false economy. A higher movement class, or a design change by the engineer, may be needed and we’ll tell you honestly. Around Goathurst Common, it’s better to renew all the failing joints at once. Send photos of each area and we’ll quote for the lot.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

From enquiry to sign-off

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. If others near Goathurst Common need work, visits can be combined. A fixed quote is given before anything starts.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

Preparing the site

  • Tell us your opening times and when work is allowed
  • Let us know about inductions and permits
  • Point out any areas we must not close

Advice

When something else is needed

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:

  • Changing the joint layout or spacing of a structure
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Movement on a scale no sealant is meant to absorb

Not sure which it is? You can speak to us on 01277 525 020 or email the details over and we’ll tell you honestly.

What we seal

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

FAQs: Goathurst Common

Can you take on a job at a hospital such as Sevenoaks Hospital?

Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

Do you cover business parks and estates near Goathurst Common, such as Salters Heath Business Centre?

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Can you fit around our working hours?

Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

What if there’s asbestos in the old mastic?

The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Which sealant will you use?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Can you quote from photographs?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.
