Expansion joint sealing for Ridley sites

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

Expansion joint sealing for commercial buildings in Ridley

For movement joints in Ridley, photographs and approximate lengths are the best start. Send them through our quote form, and we’ll arrange a site visit if needed before issuing a fixed quote. To discuss the joints first, phone 01277 525 020 or use the quote form. If you have movement joints with split or torn sealant and brittle, chalky sealant on external joints, we can put it right, on brickwork movement joints, cladding panel joints and car park decks and ramps alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Ridley, that means joint design, primers and backing rod as standard.

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

We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Leave it or put it right?

Patching the worst lengths of a joint can make sense short term. But if the rest of the run is the same age and product, it’s typically not far behind. We can price a patch and a full reseal side by side. Around Ridley, it’s better to renew all the failing joints at once. Send photos of each area and we’ll quote for the lot.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Why us?

  • Matching to RAL references, product permitting
  • Joints cleaned back to sound surfaces
  • Our applicators hold CSCS cards
  • Colour agreed before work starts

How a job runs

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. Rural sites near Ridley may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. We start with photos, approximate lengths and any drawings, visiting where needed.
  2. We compare each joint’s width with the movement and the sealant’s capability.
  3. Old sealant and debris are cut out of every joint.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Getting the site ready

  • Move anything stored against the joints
  • Tell us your opening times and when work is allowed
  • Send asbestos survey details if the building is pre-2000

Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Advice

When it isn’t the sealant

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:

  • Waterproofing layers buried beneath the sealant
  • Joints too narrow for the movement, which need redesigning by the engineer
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)

If you are not sure, just call 01277 525 020 or use the quote form and we will give you a straight answer before you book.

Joints and surfaces we work on

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

Work for main contractors and building owners

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

When to bring in a specialist

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Questions about Ridley

Is a smaller place like Ridley outside your area?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

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

Rarely. Work is phased around your operations. Tell us which hours and entrances we can use and we will plan from there.

Are you fully insured?

Yes. We’re fully insured, including public liability cover.

What if the joint edges are damaged?

Sound edges are essential. Where they’ve broken up, we will tell you they need repairing first, so the new seal has something to grip.

Is it fine to apply new sealant on top of old?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Are expansion joints and movement joints the same thing?

The general name is movement joint, and expansion joint is one common type. In everyday use the two names are often swapped, and the sealing method is much the same.

Does the weather affect the work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Joints that move: notes for Ridley

Less than 3 miles from Ridley there are at least three named estates and business parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. Rainfall across the South East, Ridley included, is lower than in many parts of the UK. External joints still wait for dry conditions, and winter de-icing salt on car parks and ramps works into any open joint.

Warehouse floors on estates like Bowes Industrial Centre, 1.3 miles east of Ridley, carry pallet trucks and forklifts over every saw-cut joint. Schools like Meopham School often have long brick elevations with movement joints that age quietly. Across sites such as Heaver Farm Trading Estate (1.4 miles west of Ridley), floor and movement joints can be sealed in phases so units keep working.

Ridley is about 6 miles south of Northfleet, in Kent. Any commercial site in Ridley is covered, whether it’s a single job or part of a planned programme. 931 places across Kent fall within our area, Ridley among them. London is covered too, around 21 miles from Ridley.

We cover the TN15 postcode districts for movement joints. If your building is just outside Ridley, we cover New Street (1 mile east), Hodsoll Street (1 mile south), South Street (1 mile east), New Ash Green (1 mile north-west) and Culverstone Green (2 miles south-east). Further afield, our area takes in Maidstone (11 miles south-east), Dartford (8 miles north-west), Sevenoaks (8 miles south-west), Royal Tunbridge Wells (15 miles south), Gravesend (6 miles north-east) and Tonbridge (11 miles south).

What the job involves on each surface

Internal floor movement joints

Warehouse and retail floors have saw-cut induced joints and construction joints. A semi-rigid filler is common in trafficked industrial floors and a flexible sealant where the joint moves more.

Brickwork and blockwork joints

Long brick and block elevations have movement joints at intervals. We use a sealant rated for the movement, typically low-modulus laid over backing rod at the correct depth.
