Expansion joint sealing for businesses in Glassenbury

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Expansion joint sealing in Glassenbury

Long runs of brick or block have movement joints built in. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal comes out, backing goes in and a sealant with the right movement class is applied, primed where the manufacturer specifies. If you have movement joints with split or torn sealant and joints where the bead has lost adhesion, we can put it right, on car park decks and ramps, cladding panel joints and precast concrete panel joints alike. Facilities teams, main contractors and managing agents in Glassenbury tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Around smaller places such as Glassenbury, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

A 12-month guarantee applies to all our work. Should something we installed fail, call 01277 525 020 or email drawings and photos and we’ll come back to it.

Aftercare for building managers

Once the work is signed off, a little attention goes a long way:

  • Put movement joints on the planned maintenance inspection round
  • Brief car park operatives to protect joint lines during winter clearance
  • Keep traffic off new joints until the cure time is up
  • Treat a small split as a warning, not a cosmetic issue

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. Inspecting the whole run is worth the effort. We will tell you which movement joints need doing now and which can wait.

General trades versus a specialist

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

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, which is what makes a joint last.

Common questions from Glassenbury clients

Would you work within a site like Benenden Hospital?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is Glassenbury too small for you to travel to?

Not at all. Glassenbury is within our area. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

What’s the quickest route to a quote?

You can use the quote form on this site; alternatively, call the office on 01277 525 020 or send photos by email. Include photos or drawings if you have them.

Can a joint be sealed if the edges are broken?

A bond is only as strong as the material behind it, so we will tell you if the edges need repairing before sealing. Where it’s visible beforehand, we will say so when we quote.

Can you send site paperwork?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

Do you need to see the site first?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.

Are expansion joints and movement joints the same thing?

The terms overlap a great deal. A movement joint allows for expansion, contraction, shrinkage and loading, and the seal across it keeps water and debris out.

What sets the cost

A fixed quote reflects the actual work. It allows for:

  • Phasing around occupants
  • Access and working height
  • Backing rod, priming and other preparation
  • Quantities, in metres or numbers

A quote for movement joints depends on quantities, condition and access, and any specification that applies. Call for a quote.

Sending details for a quote

A good diagnosis starts with the right details. Let us know:

  • The site address and postcode
  • What the building is and how it’s used
  • Approximate linear metres or a joint schedule
  • Clear photos of the problem areas

Need a figure for a tender or a budget? We’ll quote against your scope and drawings that you can work with. If you have questions first, speak to us on 01277 525 020 or send photos by email.

Signs you need expansion joint sealing in Glassenbury

When a bead pulls away from one face, it has lost adhesion. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes, and it’s common on joints sealed in a hurry.

It’s worth sending us details if you spot any of the following:

  • Chipped joint edges on forklift routes
  • Rain penetration at brick or block movement joints
  • Car park joints leaking onto vehicles below
  • Weathered movement joint sealant that no longer flexes

For buildings at a park such as Hartley Dyke Business Centre, which lies south-east of Glassenbury, brick and panel movement joints are easy to forget until one leaks.

  • How the existing material will be dealt with
  • Whether their applicators hold CSCS cards
  • Are they CHAS accredited or on Constructionline?

Questions to ask before you appoint anyone

When something else is needed

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

  • Joints too narrow for the movement, which need redesigning by the engineer
  • Waterproofing layers buried beneath the sealant
  • Movement on a scale no sealant is meant to absorb

If in doubt, call 01277 525 020 or email drawings and photos and we’ll say what we think.

Where we work in Glassenbury

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

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For work around Glassenbury, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  2. We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Getting the site ready

  • Make sure the joints can be reached
  • Let building users know which areas are affected
  • Share your working hours and any access restrictions

Slabs, ramps and loading bays in Glassenbury

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, while winter salting gets into any joint left open. Glassenbury has two named business or industrial parks inside a 3-mile radius. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

Phasing is what makes joint work possible on busy sites such as Hawkhurst Station Business Park (2.8 miles south of Glassenbury): one bay, aisle or car park row at a time. Hospitals like Benenden Hospital (to the east of Glassenbury) have multi-storey or surface car parks whose joints carry vehicles round the clock.
