Need expansion joint sealing in Woodside?

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Keeping the joints sound

After handover, a little attention goes a long way:

  • Brief car park operatives to protect joint lines during winter clearance
  • Leave barriers in place until fresh joint sealant has cured
  • Treat a small split as a warning, not a cosmetic issue
  • Inspect exposed joints once the cold weather has passed

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. A routine sweep is the simplest protection.

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. Keeping the filler or sealant sound protects the floor.

General trades versus a specialist

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.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

How the quote is worked out

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

  • How much existing material needs removing
  • Working within restricted access windows
  • Backing rod, priming and other preparation
  • Distance, for remote addresses

A quote for movement joints depends on how many there are, their condition and the access, plus any specification you’re working to. Ask us for a fixed quote.

Sending details for a quote

Good information means a firmer quote. Helpful details to send:

  • The site address and postcode
  • The product your specification calls for
  • Access details, including height
  • The type of building and who uses it

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

Honest limits

Being straight saves everyone time. Fresh joints won’t solve:

  • Leaks coming from the membrane rather than the joint seal
  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Cracking or settlement that calls for an engineer’s assessment

Not sure which it is? You can phone 01277 525 020 or email the details over and we’ll tell you honestly before you book.

Where we work in Woodside

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

On site: what to expect

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access, and our waste is bagged and taken away as we go. For a site in Woodside, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. You get a fixed quote with the product and its movement capability stated.
  3. Old sealant and filler are cut out and the joint faces cleaned back to sound material, flagging any broken edges that need repair before sealing.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. Each joint is inspected and handed over with our 12-month guarantee.

What we need from you

  • Send asbestos survey details if the building is pre-2000
  • Tell us your opening times and when work is allowed
  • Let us know about inductions and permits

What happens if it’s left?

On a car park, resealing joints in phases keeps the deck open. Work can be planned so parts of the deck stay open, compared with a full closure. Tell us what has to stay open and we will plan around it. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

What you get with us

  • RAL and finish matching where the product range allows
  • Products installed to the manufacturer’s instructions
  • A fixed quote before work starts
  • Fully insured

Expansion joint sealing around Woodside: how the place shapes the job

Common questions from Woodside clients

Is Woodside off your patch?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Can you work at a site such as Hill Farm Avenue Industrial Estate, by Woodside?

Yes. Estates, retail parks and business parks around Woodside, Hill Farm Avenue Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Is colour matching possible?

That depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

Are you fully insured?

Yes. We’re fully insured, and the certificate can go with your quote.

Can you fit around our working hours?

The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Can a joint be sealed if the edges are broken?

Broken arrises have to be put right before resealing, and we will point out where that’s the case. Sealing over them leads to early failure.
