A campus such as University for the Creative Arts (to the south-east of Dora's Green) has long runs of movement joint in its buildings, decks and paving. At a retail site such as Farnham Retail Park, 2.4 miles east of Dora's Green, trolleys, cages and cars run over floor and slab joints all day.

Expansion joint sealing for commercial buildings in Dora's Green

Our movement joint work takes in walls, panels, decks and floors: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. The product depends on the movement, the weather and anything that runs over it, and we will confirm the choice in the quote. Site teams most often ask us about joints packed with grit and debris and water getting into the wall through a failed joint, across podiums and floor movement joints, car park decks and ramps and cladding panel joints. A specialist sealant contractor works differently from a general builder: in Dora's Green, that means joint design, primers and backing rod as standard.

For a site near Dora's Green, measurements and photos up front mean one trip where possible, with the right materials on hand. Note joint widths and the traffic that uses them, and we’ll take it from there.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Work for main contractors and building owners

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Common problems we fix in Dora's Green

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.

Typical triggers for a call:

  • Rain penetration at brick or block movement joints
  • Previous reseals laid over old sealant
  • Brittle, chalky sealant on external joints
  • Movement joints with split or torn sealant

At places like Farnham Business Park, 2 miles to the south-east of Dora's Green, joints are sealed a section at a time so operations carry on.

Before you book anyone

  • Whether their applicators hold CSCS cards
  • Health and safety accreditation such as CHAS
  • How joint depth will be controlled
  • Can the work be phased to keep areas open?

Choosing a commercial sealant contractor

On site: what to expect

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases, and our waste is bagged and taken away as we go. For a building around Dora's Green, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  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. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

What we need from you

  • Share the asbestos register for older buildings
  • Arrange parking or a loading space
  • Let us know about inductions and permits

Questions we’re asked in Dora's Green

Is Coxbridge Business Park, near Dora's Green, within your area?

Yes, sites like Coxbridge Business Park are within our area, along with the rest of Dora's Green. Send details of the unit and the work through our quote form for a quick quote.

Is Dora's Green too small for you to travel to?

Not at all. Dora's Green is within our area. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Do you take on small jobs?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

How long does movement joint sealing take?

Allow a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. We confirm the timescale with the quote.

Are expansion joints and movement joints the same thing?

The terms overlap a great deal. A movement joint allows for expansion, contraction, shrinkage and loading while the sealant stops grit and water getting in.

How do we ask for a quote?

You can use the quote form on this site; alternatively, phone 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.

Does the weather affect joint sealing?

Sealant needs a dry joint and a temperature within the product’s range. Frost, rain and condensation on steel or concrete can hold up external work, so we plan with the forecast in mind.

Why act early in Dora's Green

Closing a car park for a reseal is rarely an option. Phased work by bay or zone lets the rest stay in use, compared with a full closure. We agree phasing with you before work starts. Converted and older buildings near places like Dora's Green tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

What you get with us

  • Constructionline member
  • Fully insured, including public liability cover
  • A range of standard colours, depending on the product
  • A fixed quote before work starts

How the quote is worked out

We price every job individually. The things that drive the figure:

  • Induction, permit and paperwork requirements
  • Distance, for remote addresses
  • Quantities, in metres or numbers
  • Working within restricted access windows

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

Details that help us quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • Anything awkward about access or site hours
  • Where the site is, with the postcode
  • Rough lengths or quantities, or drawings if you have them
  • What the building is and how it’s used

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or speak to us on 01277 525 020 or email us to discuss it first.

When it isn’t the sealant

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

  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Waterproofing layers buried beneath the sealant
  • A joint that has to be widened or re-detailed before it can work

If in doubt, call 01277 525 020 or email the details over and we will say what we think before you book.

What we seal
