Need expansion joint sealing in Hinxworth?

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

What the job involves on each surface

Podium joints

Podiums take foot traffic, planters and weather. A sealant suited to both traffic and exposure is used.

Cladding panel joints

Cladding panels move more than masonry as they heat and cool. A sealant with the right movement class is chosen, and we will confirm the colours available for the specified product.

Expansion joint sealing for commercial buildings in Hinxworth

Buildings and slabs are never completely still: temperature, moisture, shrinkage and loading all make materials grow and shrink. Movement joints are where that movement is absorbed and the seal across each one keeps out water and grit. We seal and reseal movement joints in walls, panels, decks and floors. We work on blockwork control joints, cladding panel joints and brickwork movement joints, and the failures we’re asked to look at most are rain penetration at brick or block movement joints and weathered movement joint sealant that no longer flexes. For commercial sealant work in Hinxworth, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

For a site near Hinxworth, measurements and photos up front mean one trip where possible, with the right materials on hand. Note joint widths and the traffic that uses them, and we will take it from there.

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.

Quoting for work in Hinxworth

The price varies from site to site. Expect it to depend on:

  • Location, for remote and island sites
  • Which sealant the job calls for
  • Quantities, in metres or numbers
  • Working within restricted access windows

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote when you are ready.

Details that help us quote

Good information means a firmer quote. Helpful details to send:

  • Access details, including height
  • Any dates the work must fit around
  • Where the site is, with the postcode
  • Photos of the joints, close up and from further back

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, give us a call on 01277 525 020 or send photos by email.

On site: what to expect

Before we leave any area, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. Smaller jobs around Hinxworth can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. We look at the joints, their width and how they’ve failed.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. We strip out the old seal and prepare the faces.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  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.

Preparing the site

  • For older buildings, check the asbestos register before work
  • Share your working hours and any access restrictions
  • Clear stock, furniture or equipment away from the joints

When to bring in a specialist

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

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 normally costs more in the end than doing them right.

Common problems we fix in Hinxworth

On trafficked joints, wheels and salts do the damage. Tyres and wheels press on the edges and the sealant, while grit and salts work into any gap. A sealant that isn’t trafficable won’t last there.

Most enquiries start with something like this:

  • Water getting into the wall through a failed joint
  • Movement joints with split or torn sealant
  • Expansion joints filled with dirt and stones
  • Hardened, cracked sealant on exposed facades

Phasing is what makes joint work possible on busy sites such as A1 Retail Park (2.5 miles north-west of Hinxworth): one bay, aisle or car park row at a time.

Questions to ask before you book

  • Whether their applicators hold CSCS cards
  • Which product they’ll use, and why it suits the joint
  • Health and safety accreditation such as CHAS
  • The terms of the workmanship guarantee

Questions to ask before you appoint anyone

Hinxworth: questions and answers

Can you work at a site such as Stratton Business Park, by Hinxworth?

Yes. We cover Hinxworth and the area around it, including industrial estates, business parks and retail parks such as Stratton Business Park. Photos and a short description are enough for a first look.

Is Hinxworth too small for you to travel to?

Not at all. Hinxworth is within our area. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Who decides which product is used?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Are expansion joints and movement joints the same thing?

Movement joint is the broad term for any joint built in to let a structure move. On site, people tend to use them interchangeably.

What guarantee do you give on joint sealing?

A 12-month guarantee covers our workmanship. Keeping joints clear of debris helps them last.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

Why has the sealant in our expansion joints split?

Most often the movement is too much for the product or the joint width. That’s why we check width, depth and movement class before quoting.

Traffic, movement and joints around Hinxworth

Two named trading, business or retail sites lie within about 3 miles of Hinxworth. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. Hinxworth sits in one of the drier corners of the country, the South East. Even so, yard and car park joints are only sealed when they’re dry and clean, and where de-icing salt is spread in winter, open joints let it in.

Office parks like Stratton Business Park, 2.2 miles to the north-west of Hinxworth, have decks, ramps and clad elevations whose joints take movement every day.
