Expansion joint sealing across Mowshurst

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

Diagnose, treat, sign off

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before the next one starts. If others near Mowshurst need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. You get a fixed quote with the product and its movement capability stated.
  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. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

Before we start on site

  • Make sure the joints can be reached
  • Let us know about inductions and permits
  • Share the asbestos register for older buildings

Advice

How we handle expansion joint sealing in Mowshurst

Buildings and slabs are never completely still: temperature, moisture, shrinkage and loading all make materials grow and shrink. Expansion and movement joints are built in so the structure can move without cracking, and the sealant in them keeps water and debris out. We seal and reseal movement joints in walls, panels, decks and floors for buildings in Mowshurst. Site teams most often ask us about water dripping through deck or ramp joints and expansion joints split through the centre of the bead, across brickwork movement joints, blockwork control joints and car park decks and ramps. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Mowshurst is the same: the right product in a properly prepared joint.

Halls, schools and small commercial buildings near places like Mowshurst have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Honest limits

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:

  • Movement on a scale no sealant is meant to absorb
  • Damaged metal nosings or cover plates over a joint
  • Waterproofing layers buried beneath the sealant

Not sure which it is? You can call the office on 01277 525 020 or email drawings and photos and we’ll tell you honestly.

What we seal

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

Looking after the joints

To get the most from the new sealant:

  • Include every elevation and deck joint in periodic inspections
  • Keep racking legs and heavy point loads off floor joints
  • Look over external and deck joints after a hard winter
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints

Every joint we seal is backed by a 12-month guarantee on workmanship. Keep the handover details, product and date with your O&M records, so the next reseal starts with the facts.

Joints sealed at the same time generally fail around the same time. It pays to check every joint, not just the obvious one so you can prioritise and budget. We will tell you which movement joints need doing now and which can wait.

Surface by surface

Brickwork and blockwork joints

Mortar snots and debris in the joint stop it working. We clear the joint fully before sealing and flag any joint that seems undersized.

Podium joints

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

Where floor joints take the most wear near Mowshurst

Mowshurst lies roughly 21 miles out from central London. The roads out of London are lined with trade parks and distribution sheds. Mowshurst sits in one of the drier corners of the country, the South East. 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.

In a school such as Edenbridge Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. Hospitals like Edenbridge and District War Memorial Hospital (1.4 miles south of Mowshurst) have multi-storey or surface car parks whose joints carry vehicles round the clock.

Mowshurst is about 7 miles north-east of East Grinstead, in Kent. Our applicators travel to Mowshurst for work on movement joints, handled exactly as we handle every other area. Mowshurst is one of 931 places we cover in Kent for movement joints. For work in that direction, see our London page.

How the quote is worked out

Before we quote, we look at:

  • Removal of failed or old sealant
  • Specialist products, such as fire-rated or hygienic sealants
  • Backing rod, priming and other preparation
  • Travel to remote or island sites

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Details that help us quote

For an accurate fixed quote, we need a clear picture of the site. Send us:

  • Drawings or a marked-up plan, if available
  • Any dates the work must fit around
  • The asbestos register, for older buildings
  • A wide shot and a close-up of the area

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

Mowshurst: questions and answers

Is Mowshurst too small for you to travel to?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Do we have to stop operations in Mowshurst while the joints are sealed?

Usually not: we work in sections and hand each one back once it has cured. The phasing plan comes with the quote.

Can you work while the building is occupied?

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

Are you insured?

Yes. We’re fully insured, and the certificate can go with your quote.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

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. We cut out the old seal and prepare the faces every time. Around Mowshurst, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

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