Signs you need expansion joint sealing in Highmoor

Some joints were never sealed with the right product. A stiff or general-purpose sealant across a joint with large movement won’t cope. BS EN ISO 11600 classifies building sealants by movement capability, and specifications often refer to it.

Look out for the following:

  • Torn sealant in brick or block movement joints
  • Debris jammed in movement joints
  • Sealant peeling off one face of the joint
  • Car park joints leaking onto vehicles below

Office parks like Vanalloys Business Park (1 mile south-west of Highmoor) have decks, ramps and clad elevations whose joints take movement every day.

Questions to ask before you book

  • How the joint faces will be prepared and primed
  • Will RAMS and insurance details be available?
  • Will failed sealant be removed rather than covered?
  • The named product and why it was chosen

Choosing a commercial sealant contractor

Why it’s worth doing now in Highmoor

Closing a car park for a reseal is rarely an option. Work can be planned so parts of the deck stay open without shutting the whole car park. Tell us what has to stay open and we’ll plan around it. Older rural buildings around Highmoor move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Pricing movement joints depends on how many there are, their condition and the access. Ask us for a fixed quote.

What you get with us

  • Specification-led, product-correct work
  • Clear, fixed quotes
  • Public liability insurance in place
  • Standard and matched colours in many product ranges

See our cost guide or our accreditations.

Keeping the joints sound

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Leave barriers in place until fresh joint sealant has cured
  • Raise snow-clearing blades over deck joints where possible
  • Keep stones and debris out of open joint lines
  • Report split or peeling joint sealant early

Fresh joint sealant needs its full cure time before it takes traffic or water. The time varies with product, conditions and joint depth. Barriers left in place until then protect the finish.

An open joint fills with grit, and a joint full of grit can’t close. The arrises crack and break away under the load. A sound seal keeps the joint working.

FAQs: Highmoor

Is a smaller place like Highmoor outside your area?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Must our site in Highmoor stop work while the joints are done?

Rarely. Work is phased around your operations. We agree the sequence and timings with you before we start.

Are expansion joints and movement joints the same thing?

It’s a deliberate gap that lets the structure move without cracking. Expansion joint is a name often used for the same thing.

Does the weather affect the work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

What timescale should we allow for resealing expansion joints?

Allow anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. Timings are set out in the quote along with the phasing plan.

What about RAMS and site documents?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

Can you quote from photos?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.

Quoting for work in Highmoor

Quotes vary with the job. It mainly depends on:

  • The product specified
  • Site requirements such as inductions and permits
  • Whether old sealant has to be cut out first
  • Any access equipment needed

The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

What to include in your enquiry

We can often quote from photographs and a few details. Please tell us:

  • The site address and postcode
  • How the joints are reached, and at what height
  • The type of building and who uses it
  • Drawings or a marked-up plan, if available

To get a fixed quote, call 01277 525 020 or use the quote form, telling us the site location and the nature of the job. You can also send details through our quote form.

Different surfaces, different methods

Brickwork and blockwork joints

Brick and block edges need careful preparation. We clean them back to sound material and prime where the manufacturer specifies, then seal and tool the joint.

Cladding panel joints

We confirm what access is in place before pricing. Photos taken near the joints help us price accurately.

How a job runs

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work usually 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. Rural sites near Highmoor may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. We look at the joints, their width and how they’ve failed.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Each joint is inspected and handed over with our 12-month guarantee.

What we need from you

  • Clear stock, furniture or equipment away from the joints
  • Share the asbestos register for older buildings
  • Send any specification or drawings in advance
