Expansion joint sealing for commercial buildings in Westwood

Joints in car park decks and ramps are among the hardest-working in any building. Tyres load the edges, and de-icing salts and water work into any gap; water dripping through to the deck below is often the first sign. We reseal deck and ramp joints with a trafficable sealant chosen for the movement and the work can be phased so parts of the car park stay open. Site teams most often ask us about rain penetration at brick or block movement joints and layers of sealant in a movement joint, on cladding panel joints, blockwork control joints and car park decks and ramps. Facilities teams, main contractors and managing agents in Westwood tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Halls, schools and small commercial buildings near places like Westwood have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

Where floor joints take the most wear near Westwood

Westwood sits in one of the drier corners of the country, the South East. External joints still wait for dry conditions, and gritting in cold spells finds its way into open joints. Less than 3 miles from Westwood there are at least three named estates and business parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

Sites like Darent Valley Hospital, 2.4 miles to the north-west of Westwood, carry ambulances, deliveries and visitors’ cars over their road and deck joints. Across sites such as Bluewater Shopping Centre (2.3 miles north-west of Westwood), floor and movement joints can be sealed in phases so units keep working. Campuses like University of Greenwich (to the north-west of Westwood) mix old and new buildings, with movement joints wherever they meet.

Westwood is about 3 miles south of Swanscombe, in Kent. Our applicators travel to Westwood for work on movement joints. 931 places across Kent fall within our area, including Westwood. We also cover London, some 18 miles away.

Anyone looking for expansion joint sealing in DA13 and DA2 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. If your site is on Westwood Road and Highcross Road or close by, send details and we will quote for movement joints. We also cover Grubb Street (1 mile south-west), Green Street Green (1 mile west), Bean (1 mile north-west), St Margarets (2 miles west) and Darenth (2 miles west) for movement joints. Nearby towns on our patch include Maidstone (14 miles south-east), Dartford (4 miles north-west), Sevenoaks (10 miles south-west), Gravesend (4 miles east), Tonbridge (15 miles south) and Northfleet (3 miles north-east).

On site: what to expect

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, then reopened once the sealant allows before we move to the next. Rural sites near Westwood may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  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. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Finished joints are checked and backed by our 12-month guarantee.

Before we start on site

  • Arrange parking or a loading space
  • Share the asbestos register for older buildings
  • Move anything stored against the joints

Advice

Questions we’re asked in Westwood

Is Westwood off your patch?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Is a hospital such as Darent Valley Hospital somewhere you can work?

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.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Which sealant will you use?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

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

They’re closely related. A movement joint allows for expansion, contraction, shrinkage and loading, and the seal across it keeps water and debris out.

Can staff carry on working while you’re here?

Usually, yes. We phase the work so most of the building stays in use, with each area protected and signed.

What affects the price in Westwood

Quotes vary with the job. It mainly depends on:

  • Joint width, depth and condition
  • Quantities, in metres or numbers
  • Whether the work must be split into stages
  • Distance, for remote addresses

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

What we need to price the job

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • Whether an asbestos survey exists
  • The site address and postcode
  • Any specification or named product
  • Whether the building will be occupied during the work

Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. For a chat about it beforehand, call the office on 01277 525 020 or email a schedule or drawings.

What happens if it’s left?

Some quotes just add sealant over the old bead. A bead laid on top of the failed one neither grips nor flexes properly and soon lets go. Full removal and preparation is in every quote. Around Westwood, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we will quote for the lot.

The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.

Different surfaces, different methods

Concrete and precast panel joints

Joints between precast panels open and close with temperature and loading. The sealant needs the right movement capability and a controlled depth.

Podium joints

Podiums take foot traffic, planters and weather. We choose a product that copes with feet, wheels and weather.

When something else is needed

Honesty saves time and money. New sealant won’t cure:

  • Changing the joint layout or spacing of a structure
  • Cracking or settlement that calls for an engineer’s assessment
  • Crumbling edges that would give a new bead nothing sound to grip

Not sure which it is? You can call the office on 01277 525 020 or send details through our quote form and we’ll tell you honestly.

Joints and surfaces we work on

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

Building owners, agents and FMs in Westwood

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Westwood can sit alongside others in a wider programme across Kent.
