Expansion joint sealing in Furnace Wood, done properly

Joint design counts for as much as the sealant itself. The joint has to be wide enough for the expected movement and the sealant’s movement capability. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises, and the bead is tooled so it grips the two faces alone. We work on podiums and floor movement joints, precast concrete panel joints and cladding panel joints, and what we are called in for most is water dripping through deck or ramp joints and spalled or broken joint edges in floors and decks. Facilities teams, main contractors and managing agents in Furnace Wood tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Around smaller places such as Furnace Wood, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Site staff or a sealant specialist?

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.

General builders and handymen seal joints, but it isn’t their main trade. 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.

From enquiry to sign-off

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work typically takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. Smaller jobs around Furnace Wood can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. We look at the joints, their width and how they’ve failed.
  2. You get a fixed quote with the product and its movement capability stated.
  3. We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Finished joints are checked and backed by our 12-month guarantee.

Getting the site ready

  • Clear stock, furniture or equipment away from the joints
  • Tell staff and tenants when we’ll be in
  • Point out parking and an unloading spot

Getting a fixed quote

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, speak to us on 01277 525 020 or email the details over.

Honest limits

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:

  • Leaks coming from the membrane rather than the joint seal
  • A joint that has to be widened or re-detailed before it can work
  • Damaged metal nosings or cover plates over a joint

If you are not sure, just speak to us on 01277 525 020 or use the quote form and we will give you a straight answer.

Joints and surfaces we work on

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

Cost factors for movement joints

The price varies from site to site. It mainly depends on:

  • Which sealant the job calls for
  • The size and state of each joint
  • Site requirements such as inductions and permits
  • Whether old sealant has to be cut out first

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 will have a fixed figure to work with.

What to include in your enquiry

To price the job accurately, we need to understand the site. Useful things to include:

  • The type of building and who uses it
  • Drawings or a marked-up plan, if available
  • The product your specification calls for
  • Access details, including height

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.

Why act early in Furnace Wood

Closing a car park for a reseal is rarely an option. Work can be planned so parts of the deck stay open. Tell us what has to stay open and we will plan around it. Halls, stores and units around places like Furnace Wood may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Questions about Furnace Wood

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

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Do you cover business parks and estates near Furnace Wood, such as Silverwood Industrial Estate?

Yes, sites like Silverwood Industrial Estate are within our area, along with the rest of Furnace Wood. Send details of the unit and the work through our quote form for a quick quote.

Does the weather affect the work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

What about RAMS and site documents?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

Do you take on small jobs?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Can a joint be sealed if the edges are broken?

Sealant needs sound faces to bond to, so we will tell you if the edges need repairing before sealing. We flag it at the quote stage where we can see it.

Can staff carry on working while you’re here?

Usually, yes. We phase the work so most of the building stays in use.

Common problems we fix in Furnace Wood

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

Look out for the following:

  • Spalled or broken joint edges in floors and decks
  • Weathered movement joint sealant that no longer flexes
  • Joints where the bead has lost adhesion
  • New sealant over old, now failing

Another example is Birches Industrial Estate, which lies east of Furnace Wood, where floors and yards would be done in stages around the occupiers.

What your quote should include

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Whether old or failed sealant will be cut out, not overlaid
  • Their plan for phasing and protecting the area
  • What site paperwork they can supply
