Questions we are asked in Woodside

Is Woodside too small for you to travel to?

No. Places such as Woodside are covered as much as the big towns. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

What paperwork can you provide for a job in Woodside?

We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.

Do you guarantee expansion joint work?

The workmanship is guaranteed for 12 months from sign-off. Keeping joints clear of debris helps them last.

Does the weather affect the work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

What if the joint edges are damaged?

A bond is only as strong as the material behind it, so we will tell you if the edges need repairing before sealing. We flag it at the quote stage where we can see it.

Do you use silicone or polyurethane in movement joints?

Whatever suits the joint and the specification. We name the proposed product in the quote so there are no surprises.

Will you just go over the old sealant?

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

Expansion joint sealing in Woodside, done properly

A movement joint only works while its seal does. When the sealant splits or lets go, the gap fills with dirt and water. Resealing at the first signs of failure is far cheaper than repairing the material either side. The enquiries we see most involve sealant pulling off the joint face and chipped joint edges on forklift routes, on brickwork movement joints, precast concrete panel joints and podiums and floor movement joints. For commercial sealant work in Woodside, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Smaller community and commercial buildings around Woodside have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Honest limits

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Leaks coming from the membrane rather than the joint seal
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)

If you’re not sure, just ring 01277 525 020 or email drawings and photos and we will give you a straight answer.

Joints and surfaces we work on

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

Where floor joints take the most wear near Woodside

Woodside lies roughly 63 miles out from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors; their floors carry heavy traffic every shift. Rainfall across the South East, Woodside included, is lower than in many parts of the UK. External joints still wait for dry conditions, and where de-icing salt is spread in winter, open joints let it in.

In and around Woodside, the right filler or sealant for each joint depends on the traffic and the movement it takes.

Woodside is about 7 miles north of Andover, in Hampshire. Commercial clients in Woodside can call on us for movement joints, as part of our coverage of Hampshire. Woodside is one of 723 places we cover in Hampshire. Sites around Reading have their own page, about 26 miles away.

How the quote is worked out

  • Site requirements such as inductions and permits
  • Any access equipment needed
  • Quantities, in metres or numbers
  • The product specified

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

Before you send an enquiry

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

  • Anything awkward about access or site hours
  • Your programme or deadline
  • Photos of the joints, close up and from further back
  • Asbestos survey details if the building is older

Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote that you can work with. For a chat about it beforehand, call the office on 01277 525 020 or send photos by email.

Diagnose, treat, sign off

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before we move to the next. Smaller jobs around Woodside can be grouped with others nearby. A fixed quote is given before anything starts.

  1. We assess the joints on site or from photographs, noting widths and how each has failed.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  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.

Advice

Work for main contractors and building owners

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.

Should maintenance staff do it?

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

Common problems we fix in Woodside

Repeated failure often traces back to the wrong product. A stiff or general-purpose sealant across a joint with large movement won’t cope. BS EN ISO 11600 classifies building sealants by movement capability, and specifications often refer to it.

Common reasons buildings call us in:

  • Brittle, chalky sealant on external joints
  • Water dripping through deck or ramp joints
  • Chipped joint edges on forklift routes
  • Water getting into the wall through a failed joint

Schools such as Vernham Dean Gillum's Church of England Primary School have movement joints in their walls and floors that are easy to overlook.

What your quote should include

  • What level of public liability insurance do they hold?
  • How long is the guarantee, and what does it include?
  • Health and safety accreditation such as CHAS
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
