Expansion joint sealing for South Stoke sites

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

When to bring in a specialist

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

We’ve been sealing expansion and movement joints for over 20 years for contractors, facilities managers and owners. Our applicators are CSCS-carded, we are CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship.

Whether you call it commercial sealant work, mastic application or joint sealing, in South Stoke it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For a site near South Stoke, measurements and photos up front mean one trip where possible. Tell us the joint widths if you can, and what drives or walks over them.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Why it’s worth doing now in South Stoke

Combining joint work with other maintenance reduces set-up costs. But joints already letting water in shouldn’t wait for a programme because damage continues. Urgent joints now, the rest later, is often the sensible plan. Around South Stoke, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we will quote for the lot.

Pricing movement joints depends on quantities, condition and access. Call for a quote.

From enquiry to sign-off

On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work normally takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. For a building around South Stoke, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Before we start on site

  • Warn occupants and staff about the work
  • Tell us which areas need to stay in use
  • Share the asbestos register for older buildings

Different surfaces, different methods

Podium joints

Podium decks are exposed and often trafficked. A sealant suited to both traffic and exposure is used.

Internal floor movement joints

Warehouse and retail floors have saw-cut induced joints and construction joints. Trafficked floor joints often get a semi-rigid filler, with a flexible sealant where movement is larger.

Aftercare for building managers

Regular inspection catches problems early. In particular:

  • Keep product details with the building records for the next reseal
  • Leave barriers in place until fresh joint sealant has cured
  • Report split or peeling joint sealant early
  • Keep stones and debris out of open joint lines

Our workmanship on movement joints carries a 12-month guarantee. Record which product went into which joints in the building file, so the next reseal starts with the facts.

When one joint fails, others of the same age are rarely far behind. Inspecting the whole run is worth the effort, so the work can be planned rather than rushed. We can suggest an order, worst joints first.

Joints that move: notes for South Stoke

Central London is about 45 miles from South Stoke. The roads out of London are lined with trade parks and distribution sheds; their floors carry heavy traffic every shift. Rainfall across the South East, South Stoke included, is lower than in many parts of the UK. 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.

In and around South Stoke, the right filler or sealant for each joint depends on the traffic and the movement it takes. In a school such as South Stoke Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Common questions from South Stoke clients

Must our site in South Stoke stop work while the joints are done?

In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. The phasing plan comes with the quote.

What site paperwork comes with a job in South Stoke?

RAMS, insurance certificate, CSCS details: list what the site needs and we’ll confirm it with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Do you have public liability insurance?

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

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

How much does the work cost?

It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we will price it properly.

Is movement joint sealing guaranteed?

Our workmanship on movement joints carries a 12-month guarantee. Damage from later works or traffic loads outside the joint’s design isn’t a workmanship fault.
