For managing agents and facilities managers

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Expansion joint sealing in Balls Cross, done properly

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 is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled, primed where the manufacturer specifies. We work on cladding panel joints, podiums and floor movement joints and car park decks and ramps, and what we are called in for most is sealant pulling off the joint face and leaks through car park deck joints onto the level below. For commercial sealant work in Balls Cross, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

In and around smaller places like Balls Cross, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

When to call us in Balls Cross

When the movement exceeds the sealant’s capability, the bead tears. Cohesive failure, a split through the centre, normally means the joint or product wasn’t right for the movement. The same product in the same joint tends to fail again, so we check width and movement before quoting.

Clients typically get in touch after noticing something like this:

  • Expansion joints split through the centre of the bead
  • Previous reseals laid over old sealant
  • Brittle, chalky sealant on external joints
  • Sealant pulling off the joint face

Across sites such as Hampers Common Industrial Estate, 2.5 miles south of Balls Cross, floor and movement joints can be sealed in phases so units keep working.

Before you book anyone

  • Whether old or failed sealant will be cut out, not overlaid
  • Health and safety accreditation such as CHAS
  • The named product and why it was chosen
  • Will CSCS-carded applicators be on site?

Choosing a commercial sealant contractor

Looking after the joints

To get the most from the new sealant:

  • Keep traffic off new joints until the cure time is up
  • Keep stones and debris out of open joint lines
  • Note which joints were done, when, and with what
  • Treat a small split as a warning, not a cosmetic issue

Grit is the slow enemy of a joint seal. Stones pressed into the bead by wheels or feet can puncture it, especially on car park decks and warehouse floors. Regular sweeping keeps joint lines clear.

Unsupported floor joint edges spall under forklift and pallet-truck wheels. Damaged edges make the floor rough and wear wheels faster, and the damage spreads along the joint. Sealing early protects the edges.

Joints that move: notes for Balls Cross

The 3 miles around Balls Cross take in two named trading estates, business parks or retail parks. Their warehouses, yards and car parks are exactly where joints take the most punishment. Rainfall across the South East, Balls Cross included, is lower than in many parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and winter de-icing salt on car parks and ramps works into any open joint.

Estates like Colhook Industrial Park. (to the west of Balls Cross) combine warehouse slabs, yards and loading bays, all with joints under wheels.

Diagnose, treat, sign off

Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. If others near Balls Cross need work, visits can be combined. 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. A fixed quote follows, naming the sealant and its movement class.
  3. The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

Advice

Quoting for work in Balls Cross

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

  • Induction, permit and paperwork requirements
  • Joint width, depth and condition
  • Location, for remote and island sites
  • Which sealant the job calls for

A quote for movement joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

Before you send an enquiry

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • Rough lengths or quantities, or drawings if you have them
  • Asbestos survey details if the building is older
  • How the joints are reached, and at what height
  • The postcode of the building

The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or speak to us on 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.

What happens if it’s left?

Doing joint resealing alongside other planned works can save on access. Leaking joints need sealing now, as damage continues meanwhile. We can split the scope into urgent and planned. Older rural buildings around Balls Cross move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Why clients in Balls Cross choose us

  • Fixed quotes based on photographs, drawings or a visit
  • Specification-led, product-correct work
  • 12 months’ guarantee on every job
  • Public liability insurance in place

Common questions from Balls Cross clients

Will our site in Balls Cross have to close for joint sealing?

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

Is a smaller place like Balls Cross outside your area?

Not at all. Balls Cross is within our area. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

What guarantee do you give on joint sealing?

Our workmanship on movement joints carries a 12-month guarantee. The guarantee covers how we sealed, not damage caused afterwards.

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

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

What exactly is a movement joint?

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

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

How do we ask for a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.
