Expansion joint sealing in Sandling

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

On site: what to expect

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access, and we clear our waste as we work. If others near Sandling need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

What we need from you

  • Let building users know which areas are affected
  • Point out parking and an unloading spot
  • Confirm the product named in the specification

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Expansion joint sealing for commercial buildings in Sandling

Few joints take as much punishment as those in a car park. Wheel loads, grit and de-icing salts attack the seal and the concrete either side; water dripping through to the deck below is often the first sign. A sealant suited to traffic and the expected movement goes in and the work can be phased so parts of the car park stay open. We work on blockwork control joints, podiums and floor movement joints and car park decks and ramps, and what we’re called in for most is sealant pulling off the joint face and previous reseals laid over old sealant. A specialist sealant contractor works differently from a general builder: on jobs in Sandling, preparation and product choice get the time they need.

For a site near Sandling, measurements and photographs up front mean one trip where possible. Tell us the joint widths if you can, and what drives or walks over them.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

When to bring in a specialist

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

Warehouse floors and decks around Sandling

At least three named trading, business or retail sites lie within about 3 miles of Sandling. Their warehouses, yards and car parks are exactly where joints take the most punishment. At about 30 miles from central London, Sandling is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital, and their floor joints take forklift and pallet-truck traffic all day.

Schools such as Sandling Primary School have movement joints in their walls and floors that are easy to overlook. For an occupier at a site such as Viewpoint Industrial Estate (1.1 miles south-east of Sandling), the joints at loading doors and dock levellers typically see the hardest wear.

Sandling is about 1 mile north-west of Foley Park, in Kent. Any commercial site in Sandling is covered. Across Kent, 931 places are covered, including Sandling. Our London page has more on work in that area.

Different surfaces, different methods

Podium joints

Podium joints often sit within a waterproofing system. Where the specification calls for sealant, we reseal and flag it if the membrane looks like the source.

Cladding panel joints

Cladding panels move more than masonry as they heat and cool. A sealant with the right movement class is chosen.

Honest limits

Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:

  • Leaks coming from the membrane rather than the joint seal
  • Damaged metal nosings or cover plates over a joint
  • Broken or spalled joint edges, which need repairing before any sealant goes in

If in doubt, speak to us on 01277 525 020 or email drawings and photos and we will say what we think.

Joints and surfaces we work on

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

When to call us in Sandling

Repeated failure often traces back to the wrong product. A stiff or general-purpose sealant across a joint with large movement won’t cope. Movement capability is set out in BS EN ISO 11600.

Look out for the following:

  • New sealant over old, now failing
  • Spalled or broken joint edges in floors and decks
  • Leaks through car park deck joints onto the level below
  • Debris jammed in movement joints

A healthcare site such as The Somerfield Hospital, 1.5 miles to the south of Sandling, depends on car parks, ramps and service yards whose joints take traffic all day.

What to look for in a quote

  • What site paperwork they can supply
  • Will failed sealant be removed rather than covered?
  • The named product and why it was chosen
  • What the guarantee covers, and for how long

Our contractor checklist

Why act early in Sandling

Closing a car park for a reseal is rarely an option. 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. Around Sandling, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we will quote for the lot.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Why clients in Sandling choose us

  • Our applicators hold CSCS cards
  • Matching to RAL references, product permitting
  • Fully insured
  • Coloured sealants to suit the setting, where available

Common questions from Sandling clients

Do you take on work at healthcare sites like The Somerfield Hospital?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Is Sandling off your patch?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

What hours do you work?

We are in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

Are your applicators CSCS-carded?

Yes. Should the site need card details in advance, let us know and we will send them with the quote.

How do we ask for a quote?

The quote form is the simplest route, though you can also ring 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Does the weather affect the work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
