Expansion joint sealing for businesses in Westwell

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Should maintenance staff do it?

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

About our expansion joint sealing in Westwell

Joints in car park decks and ramps are among the hardest-working in any building. Wheel loads, grit and de-icing salts attack the seal and the concrete either side, so failed seals soon lead to leaks onto the level below and broken edges. We reseal deck and ramp joints with a trafficable sealant chosen for the movement, phasing bays so the car park can stay in use. If you have joints where the bead has lost adhesion and spalled or broken joint edges in floors and decks, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, in Westwell it comes down to the same thing: the right product in a properly prepared joint.

In and around smaller places like Westwell, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

The 12-month guarantee is for workmanship rather than 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.

How the job changes by surface

Car park decks and ramps

Water coming through deck joints is the usual first sign. We strip the old seal, prepare the edges and seal again, and we’ll tell you if any edges need repairing first.

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 and check the edges for soundness as we go.

Leave it or put it right?

Closing a car park for a reseal is rarely an option. Work can be planned so parts of the deck stay open. Tell us what has to stay open and we’ll plan around it. Halls, stores and units around places like Westwell may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Why us?

  • Colour agreed before work starts
  • Clear, fixed quotes
  • Constructionline member for supplier checks
  • Coloured sealants to suit the setting, where available

Signs you need expansion joint sealing in Westwell

Most movement joint failures come down to the joint stretching further than the sealant can take. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. The same product in the same joint tends to fail again, so we check width and movement before quoting.

It’s worth sending us details if you spot any of the following:

  • Debris jammed in movement joints
  • Previous reseals laid over old sealant
  • Leaks through car park deck joints onto the level below
  • Hardened, cracked sealant on exposed facades

Across sites such as Warren Retail Park, 2.5 miles south-east of Westwell, floor and movement joints can be sealed in phases so units keep working.

Questions to ask before you book

  • How long is the guarantee, and what does it include?
  • Whether old or failed sealant will be cut out, not overlaid
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • How they’ll work around occupants

How to choose a sealant contractor

FAQs: Westwell

Do you take on work at healthcare sites like William Harvey Hospital?

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

Can you work at a site such as Eurogate Business Park, by Westwell?

Yes. Our area takes in Westwell and its surroundings, with estates and business parks such as Eurogate Business Park included. Send details of the unit and the work through our quote form for a quick quote.

Do you reseal car park expansion joints?

Yes, we do. These joints take wheels, salt and water, so product choice matters.

Does weather matter for sealant work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

What timescale should we allow for resealing expansion joints?

The metres of joint, the access and the amount of removal decide it. Typically it takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

How much does the work cost?

Every job gets its own fixed quote. For yours, speak to us on 01277 525 020 or email a schedule or drawings with a description of the work.

Our process

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work usually takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. Smaller jobs around Westwell can be grouped with others nearby. You will have a fixed quote before work starts.

  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, and we tell you if any edges need repairing first.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  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.

Preparing the site

  • Confirm the product named in the specification
  • Tell us your opening times and when work is allowed
  • Tell staff and tenants when we’ll be in

Advice

What we can’t put right

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Crumbling edges that would give a new bead nothing sound to grip
  • Waterproofing layers buried beneath the sealant
  • Joints too narrow for the movement, which need redesigning by the engineer

If in doubt, give us a call on 01277 525 020 or email drawings and photos and we’ll say what we think.

Joints and surfaces we work on

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

Expansion joint sealing around Westwell: how the place shapes the job

Westwell sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, and gritting in cold spells finds its way into open joints. At least three named trading, business or retail sites lie within about 3 miles of Westwell. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.

Large sites such as William Harvey Hospital (4.6 miles south-east of Westwell) have car parks, service roads and long elevations with movement joints in brick and panels. Schools like The Hayesbrook School often have long brick elevations with movement joints that age quietly.
