Need expansion joint sealing in Upper Hardres?

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

Why it’s worth doing now in Upper Hardres

Spot repairs can be useful on a tight budget. The remaining sealant is often close to failing too. Where it helps, we quote both options. For buildings around smaller places like Upper Hardres, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote when you’re ready.

Why appoint us

  • Clear, fixed quotes
  • CSCS-carded applicators
  • Workmanship guaranteed for 12 months
  • Over 20 years of commercial sealing

Expansion joint sealing for commercial buildings in Upper Hardres

A movement joint only works while its seal does. When the sealant splits or lets go, the gap fills with dirt and water. Resealing at the first signs of failure is far cheaper than repairing the material either side. We work on podiums and floor movement joints, cladding panel joints and brickwork movement joints, and what we are called in for most is expansion joints filled with dirt and stones and brittle, chalky sealant on external joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Upper Hardres it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around smaller places such as Upper Hardres, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Keeping the joints sound

After handover, a little attention goes a long way:

  • Act on the first tear or lifting edge rather than waiting
  • Keep scrapers and ploughs from dragging across joint sealant
  • Check joints after long freezing spells
  • Plan racking layouts so feet don’t land on a joint

Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check. Should you spot a problem, you can phone 01277 525 020 or email drawings and photos and send a picture.

Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers and the broken length grows with every pass. Keeping the filler or sealant sound protects the floor.

Warehouse floors and decks around Upper Hardres

The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and winter de-icing salt on car parks and ramps works into any open joint. Upper Hardres is about 54 miles from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital.

For an estate such as Kent and Canterbury Hospital, which lies north of Upper Hardres, the joints in ramps, decks and long building elevations all need attention over time.

Upper Hardres is about 4 miles south of Canterbury, in Kent. Businesses, contractors and managing agents in Upper Hardres can call on us for movement joints, as part of our coverage of Kent. Upper Hardres is one of 931 places in Kent on our list. Our London page has more on work in that area, about 54 miles away.

What sealant work can’t fix

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Leaks coming from the membrane rather than the joint seal
  • Changing the joint layout or spacing of a structure
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)

Not sure which it is? You can speak to us on 01277 525 020 or send photos by email and we will tell you honestly.

Surfaces we seal

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

When to call us in Upper Hardres

With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Bonded on three faces, it can’t stretch evenly when the joint opens, which is why depth control matters.

Site and facilities staff are often the first to spot these:

  • Damp inside where a wall movement joint has failed
  • Joints packed with grit and debris
  • Water dripping through deck or ramp joints
  • Movement joints with split or torn sealant

A campus such as University for the Creative Arts (4.1 miles north of Upper Hardres) has long runs of movement joint in its buildings, decks and paving.

Questions about Upper Hardres

Is Upper Hardres too far out for you?

Not at all. Upper Hardres is within our area. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

Can you take on a job at a hospital such as Kent and Canterbury Hospital?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

What happens if it rains on the day?

Sealant needs a dry joint and a temperature within the product’s range. Frost, rain and condensation on steel or concrete can hold up external work.

Do you offer coloured sealant?

That depends on the product. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.

What will the job cost?

There isn’t a price list, because every site is different. Send photos or drawings and we’ll price it at a fixed figure.

Are you CHAS accredited?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

Our process

Occupied buildings need a little choreography. We sign and contain the area we’re in, keep walkways clear and move on in phases so staff and visitors can carry on around us. For a building around Upper Hardres, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. Old sealant and filler are cut out and the joint faces cleaned back to sound material, 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. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

Preparing the site

  • Confirm the product named in the specification
  • Share your working hours and any access restrictions
  • Tell us which areas need to stay in use

Quotes

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

Doing it in-house

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
