About our expansion joint sealing in Monk's Hill

Brickwork and blockwork walls have vertical movement joints at intervals. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled, primed where the manufacturer specifies. If you have arrises breaking up along floor joints and joints where the bead has lost adhesion, we can help, on car park decks and ramps, precast concrete panel joints and blockwork control joints alike. For commercial sealant work in Monk's Hill, you deal with one contact from quote to sign-off, whether it’s one building or several.

For a site near Monk's Hill, measurements and photographs up front mean one trip where possible, with the right materials on hand. Note joint widths and the traffic that uses them, and we’ll take it from there.

We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

How the job changes by surface

Joints between different materials

Some mixed-material joints suit a hybrid sealant. The choice depends on the substrates and how much the joint moves, and confirm it in the quote.

Internal floor movement joints

Floor joints include saw-cut joints and construction joints. A semi-rigid filler is common in trafficked industrial floors.

How a job runs

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints, and our waste is bagged and taken away as we go. Rural sites near Monk's Hill 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.
  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.

Preparing the site

  • Have the specification and drawings to hand
  • Tell us your opening times and when work is allowed
  • Move anything stored against the joints

FAQs: Monk's Hill

Is Monk's Hill too small for you to travel to?

No. Places such as Monk's Hill are covered as much as the big towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Will our site in Monk's Hill have to close for joint sealing?

Rarely. Work is phased around your operations. The phasing plan comes with the quote.

What happens if it rains on the day?

Weather matters for any external joint: rain, frost and condensation all stop sealant bonding. Indoor joints can typically carry on regardless.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

How long does movement joint sealing take?

It usually takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access, with phasing where areas must stay open. We’ll confirm when each area can be used again.

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

What causes movement joint sealant to fail?

The common causes are poor preparation, three-sided adhesion, the wrong movement class and weathering. We diagnose which one it is before resealing, because the fix differs.

After the work

For the best life from the joints:

  • Check joints after long freezing spells
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Keep scrapers and ploughs from dragging across joint sealant
  • Put movement joints on the planned maintenance inspection round

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 use the quote form and send a picture.

External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint by which time the joint has been open for a while. Catching it early keeps the water outside.

What sets the cost

Before we quote, we look at:

  • Site requirements such as inductions and permits
  • How accessible the joints are
  • The product specified
  • Whether old sealant has to be cut out first

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.

What we need to price the job

To price the job accurately, we need to understand the site. Send us:

  • Asbestos survey details if the building is older
  • Specification clauses that apply
  • The postcode of the building
  • A wide shot and a close-up of the area

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, speak to us on 01277 525 020 or send photos by email.

Warehouse floors and decks around Monk's Hill

Monk's Hill sits in one of the drier corners of the country, the South East. External slab and deck joints still need a dry, clean joint to seal, and where de-icing salt is spread in winter, open joints let it in. Monk's Hill is about 41 miles from central London. The roads out of London are lined with trade parks and distribution sheds.

In a school such as Smarden Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. For an estate such as Benenden Hospital, 4.4 miles to the south-west of Monk's Hill, the joints in ramps, decks and long building elevations all need attention over time.

Monk's Hill is about 9 miles west of Ashford, in Kent. We send applicators to Monk's Hill for movement joints. We work across 931 places in Kent, from busy centres to rural villages. There’s a separate page for London, about 41 miles away.

Work on movement joints is covered throughout TN27, for business premises of every kind. Among the streets we cover are The Cut and Smarden Road, and sites on any of them can send details for a fixed quote. We also cover Standen (1 mile south-west), Smarden (1 mile north-east), Lashenden (1 mile west), Smarden Bell (1 mile north) and Curteis' Corner (1 mile south-west) for movement joints. A short drive away, we cover Maidstone (11 miles north-west), Ashford (9 miles east), Sittingbourne (14 miles north), Faversham (15 miles north-east), Kings Hill (15 miles north-west) and Davington (15 miles north-east).

Local landmarks in Monk's Hill

We work on buildings around The Flying Horse pub, among other places. The nearest railway station is Headcorn station, about 2.5 miles north-west of the centre. Other landmarks nearby include Romden Castle (1.8 miles east) and Benenden Hospital (4.4 miles south-west).

Leave it or put it right?

Sealing over a failed movement joint is a common shortcut. A bead laid on top of the failed one neither grips nor flexes properly, so it fails quickly. Full removal and preparation is in every quote. Older rural buildings around Monk's Hill 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.

A quote for movement joints depends on how many there are, their condition and the access. Call for a quote.

When it isn’t the sealant

Being straight saves everyone time. New sealant won’t cure:

  • Waterproofing layers buried beneath the sealant
  • Changing the joint layout or spacing of a structure
  • Proprietary pre-formed expansion joint systems
