What happens if it’s left?

Combining joint work with other maintenance reduces set-up costs. Leaking joints need sealing now, as damage continues meanwhile. Urgent joints now, the rest later, is often the sensible plan. For buildings around smaller places like Stunts Green, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

How we handle expansion joint sealing in Stunts Green

Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1 and the bead bonds to the sides, never the back. If you have debris jammed in movement joints and movement joints with split or torn sealant, we can help. Facilities teams, main contractors and managing agents in Stunts Green tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Around smaller places such as Stunts Green, 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.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Aftercare for building managers

A few simple habits keep the new joints working:

  • Leave barriers in place until fresh joint sealant has cured
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Treat a small split as a warning, not a cosmetic issue
  • Brief car park operatives to protect joint lines during winter clearance

Snow ploughs and scrapers catch on joint lines. Raising blades over joints where possible protects the seal, and it’s worth checking joints once the cold weather has passed.

Once debris packs a failed joint, the structure has nowhere to expand. The arrises crack and break away under the load and the reseal becomes an edge repair as well. Keeping the seal sound avoids all of that.

Floors, slabs and movement joints in Stunts Green

The South East is one of the drier parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, while winter salting gets into any joint left open. At about 45 miles from central London, Stunts Green is within reach of the capital. The South East has large numbers of industrial estates and warehouses along the motorway corridors.

Schools such as Herstmonceux Church of England Primary School have movement joints in their walls and floors that are easy to overlook. A healthcare site such as Amberstone Hospital (1.8 miles south-west of Stunts Green) depends on car parks, ramps and service yards whose joints take traffic all day.

Cost factors for movement joints

These are the things that shape the price:

  • The size and state of each joint
  • How much there is to seal
  • How much existing material needs removing
  • Phasing around occupants

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Details that help us quote

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

  • Whether the building will be occupied during the work
  • Your programme or deadline
  • The site address and postcode
  • A wide shot and a close-up of the area

To get a fixed quote, phone 01277 525 020 or email the details over. You can also send details through our quote form.

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

On site: what to expect

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. 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 Stunts Green, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. We assess the joints on site or from photos, noting widths and how each has failed.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

What we need from you

  • Tell us which areas need to stay in use
  • Confirm the product named in the specification
  • Share your working hours and any access restrictions

Related advice

Your questions answered

Must our site in Stunts Green stop work while the joints are done?

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

Is Stunts Green too far out for you?

No. Small places get the same service as large ones. 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 your applicators hold CSCS cards?

Yes. If you need card details for site access, let us know and we’ll send them with the quote.

Will you come and look before quoting?

It depends on the job. Simple work can often be priced from photographs, and bigger or more complex jobs usually get a visit.

When is resealing likely to be due?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Do you take on small jobs?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

What if the joint edges are damaged?

Sealant needs sound faces to bond to, so broken or crumbling edges have to be repaired first. We flag it at the quote stage where we can see it.

Surface by surface

Podium joints

On podiums, the joint can belong to a larger waterproofing detail. Where the specification calls for sealant, we reseal.

Car park decks and ramps

Water coming through deck joints is the usual first sign. The old seal comes out, the edges are prepared and the joint resealed.
