Need expansion joint sealing in Dunsfold?

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Cost factors for movement joints

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Removal of failed or old sealant
  • Travel to remote or island sites
  • Access and working height
  • Joint width, depth and condition

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Before you send an enquiry

We can often quote from photos and a few details. It helps to include:

  • Approximate linear metres or a joint schedule
  • Asbestos survey details if the building is older
  • Whether the building will be occupied during the work
  • Any dates the work must fit around

Let us know the site, the scope and your timescale, and we will put a fixed quote together. The easiest way is to call 01277 525 020 or email the details over.

About our expansion joint sealing in Dunsfold

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Unsupported edges break up under wheels, so the right filler or sealant for the traffic and movement matters. If the arrises are already broken, we’ll say so before sealing and phasing can keep areas working. The enquiries we see most involve new sealant over old, now failing and car park joints leaking onto vehicles below, across blockwork control joints, precast concrete panel joints and cladding panel joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Dunsfold it comes down to the same thing: the right product in a properly prepared joint.

Jobs around smaller places like Dunsfold are planned so the whole job is done in one visit. Tell us the joint widths if you can, and what drives or walks over them.

A 12-month guarantee applies to all our work in Surrey. If an installation problem shows up, phone 01277 525 020 or email drawings and photos and we will arrange a return visit.

Doing it in-house

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.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Keeping the joints sound

To get the most from the new sealant:

  • Treat a small split as a warning, not a cosmetic issue
  • Put movement joints on the planned maintenance inspection round
  • Leave barriers in place until fresh joint sealant has cured
  • Keep stones and debris out of open joint lines

Debris does more harm to joint sealant than most people realise. Grit trodden or driven into the joint works at the surface until it tears, especially on car park decks and warehouse floors. Regular sweeping keeps joint lines clear.

On a multi-storey car park, a failed joint normally shows up as a leak onto the deck underneath. Salty water dripping through stains soffits and lands on parked vehicles and it can affect the structure over time. Sealing the joint promptly stops it at source.

Common questions from Dunsfold clients

Is Dunsfold off your patch?

Not at all. Dunsfold is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Is Littlemead Industrial Estate, near Dunsfold, within your area?

Yes. Our area takes in Dunsfold and its surroundings, with estates and business parks such as Littlemead Industrial Estate included. A few photographs and the unit address let us price the work.

What guarantee do you give on joint sealing?

A 12-month guarantee covers our workmanship and we hold public liability insurance. Regular sweeping and inspection help the joints last.

What do you charge?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we will price it properly.

How do we ask for a quote?

You can use the quote form on this site; alternatively, speak to us on 01277 525 020 or email the details over. Include photos or drawings if you have them.

What about RAMS and site documents?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

What happens if old sealant might contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

Slabs, ramps and loading bays in Dunsfold

At about 33 miles from central London, Dunsfold is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital; their floors carry heavy traffic every shift. Dunsfold sits in one of the drier corners of the country, the South East. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints.

For an occupier at a site such as Littlemead Industrial Estate, 3 miles to the north-east of Dunsfold, the joints at loading doors and dock levellers normally see the hardest wear. Hospitals like Milford Hospital (to the north-west of Dunsfold) have multi-storey or surface car parks whose joints carry vehicles round the clock.

Dunsfold is about 9 miles south of Guildford, in Surrey. We cover commercial sites throughout Dunsfold, whether it’s a single job or part of a planned programme. Dunsfold is one of 379 places in Surrey on our list for movement joints. Our Brighton page has more on work in that area (27 miles or so).

Different surfaces, different methods

Joints between different materials

Junctions between brick and render, or concrete and cladding, move independently. The product must bond to both substrates and cope with the movement, with primer where specified.

Concrete and precast panel joints

Precast panels often have surface residues that sealant won’t bond to. Proper cleaning and primer where specified give a sound bond.

From enquiry to sign-off

We bring the products specified for the job, along with primers and backing rod. 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. Rural sites near Dunsfold may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. We look at the joints, their width and how they’ve failed.
  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.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Finished joints are checked and backed by our 12-month guarantee.

What we need from you

  • Have the specification and drawings to hand
  • Tell us your opening times and when work is allowed
  • Warn occupants and staff about the work
