Looking after the joints

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Look over external and deck joints after a hard winter
  • Keep traffic off new joints until the cure time is up
  • Inspect movement joints alongside other routine building checks
  • Act on the first tear or lifting edge rather than waiting

Our workmanship on movement joints carries a 12-month guarantee. Keep the handover details, product and date with your O&M records so future maintenance isn’t guesswork.

An open joint fills with grit, and a joint full of grit can’t close. The arrises crack and break away under the load. A sound seal keeps the joint working.

How we handle expansion joint sealing in East Saltdean

Buildings and slabs are never completely still: they expand in the heat, shrink as they dry, and shift under load. Expansion and movement joints are built in so the structure can move without cracking, and the sealant in them keeps water and debris out. We seal and reseal movement joints in walls, panels, decks and floors for buildings in East Saltdean. Most enquiries involve new sealant over old, now failing and water getting into the wall through a failed joint, on podiums and floor movement joints, cladding panel joints and precast concrete panel joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in East Saltdean is the same: the right product in a properly prepared joint.

Around East Saltdean, most floor and movement joint jobs are single buildings or yards, so we gather photos and measurements first. That way the right materials come on the day and the job is done in one visit where possible.

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 are clear about what is covered before work starts.

Questions we’re asked in East Saltdean

Do you cover business parks and estates near East Saltdean, such as Meridian Shopping Centre?

Yes. Our area takes in East Saltdean and its surroundings, with estates and business parks such as Meridian Shopping Centre included. To start, just give us a call on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

Is East Saltdean off your patch?

Not at all. East Saltdean is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

When can you be on site?

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

What’s the difference between an expansion joint and a movement joint?

Movement joint is the broad term for any joint built in to let a structure move. On site, people tend to use them interchangeably, and the sealing method is much the same.

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Does the weather affect joint sealing?

Sealant needs a dry joint and a temperature within the product’s range. Cold, damp or frosty mornings can stop work outside.

What timescale should we allow for resealing expansion joints?

Expect a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints, with phasing where areas must stay open. Cure time before reopening is confirmed on the day.

Site staff or a sealant specialist?

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Common problems we fix in East Saltdean

The edges of the material can fail rather than the sealant. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip, so we tell you if the edges need repairing first.

Typical triggers for a call:

  • Damp inside where a wall movement joint has failed
  • Sealant pulling off the joint face
  • Hardened, cracked sealant on exposed facades
  • Spalled or broken joint edges in floors and decks

At a retail site such as Meridian Shopping Centre, 1.4 miles to the east of East Saltdean, joints in car parks, service yards and sales floors carry cars, cages and trolleys every day.

What to look for in a quote

  • Their approach to joint depth and backing
  • What level of public liability insurance do they hold?
  • Whether primer will be used where the manufacturer specifies it
  • Are they CHAS accredited or on Constructionline?

Choosing a commercial sealant contractor

Different surfaces, different methods

Car park decks and ramps

Deck and ramp joints take tyre loads, grit and de-icing salts. A trafficable sealant suited to the movement goes in, phased so parts of the car park stay open.

Internal floor movement joints

Warehouse and retail floors have saw-cut induced joints and construction joints. A semi-rigid filler is common in trafficked industrial floors.

Quoting for work in East Saltdean

There’s no standard rate for sealant work, because every site is different. What we look at:

  • How much there is to seal
  • Access and working height
  • Removal of failed or old sealant
  • Induction, permit and paperwork requirements

A quote for movement joints depends on quantities, condition and access, and any specification that applies. Call for a quote.

Details that help us quote

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

  • Whether an asbestos survey exists
  • Rough lengths or quantities, or drawings if you have them
  • Where the site is, with the postcode
  • Anything awkward about access or site hours

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or call the office on 01277 525 020 or send photos by email if you’d rather talk the job through.

Our process

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before we move to the next. If neighbouring businesses or buildings around East Saltdean need work too, visits can be combined. Tell us your site hours and we will plan around them.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. Old sealant and filler are cut out and the joint faces cleaned back to sound material, and we tell you if any edges need repairing first.
  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. Finished joints are checked and backed by our 12-month guarantee.

Before we start on site

  • Let building users know which areas are affected
  • Have the specification and drawings to hand
  • Point out any areas we must not close
