Expansion joint sealing for Walton-on-Thames sites

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

What we can’t put right

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

  • A joint that has to be widened or re-detailed before it can work
  • Proprietary pre-formed expansion joint systems
  • Cracking or settlement that calls for an engineer’s assessment

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.

Where we work in Walton-on-Thames

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

How we handle expansion joint sealing in Walton-on-Thames

Brickwork and blockwork walls have vertical movement joints at intervals. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal comes out, backing goes in and a sealant with the right movement class is applied. Most enquiries involve rain penetration at brick or block movement joints and sealant peeling off one face of the joint, on precast concrete panel joints, blockwork control joints and cladding panel joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Walton-on-Thames is the same: the right product in a properly prepared joint.

In a town the size of Walton-on-Thames, floor joints are mostly in industrial and trade units, supermarkets and car parks. Small units are often busy, so joints are done at times that suit the occupier.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Why act early in Walton-on-Thames

Patching the worst lengths of a joint can make sense short term. But if the rest of the run is the same age and product, it’s usually not far behind and repeated access costs add up. We can price a patch and a full reseal side by side. Many buildings in towns like Walton-on-Thames have been extended or altered, so joints between old and new are often the first to go. Renewing them before water gets in protects the fabric.

There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

Questions about Walton-on-Thames

Must our site in Walton-on-Thames stop work while the joints are done?

In most cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. We agree the sequence and timings with you before we start.

Is North Weylands Industrial Estate, near Walton-on-Thames, within your area?

Yes, sites like North Weylands Industrial Estate are within our area, along with the rest of Walton-on-Thames. Send details of the unit and the work through our quote form for a quick quote.

When can you be on site?

Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Are you fully insured?

Yes. We are fully insured, including public liability cover.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

How the quote is worked out

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • Any access equipment needed
  • Travel to remote or island sites
  • The product specified
  • How much existing material needs removing

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Details that help us quote

To price the job accurately, we need a clear picture of the site. Send us:

  • A wide shot and a close-up of the area
  • Where the site is, with the postcode
  • Specification clauses that apply
  • Any dates the work must fit around

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, phone 01277 525 020 or email a schedule or drawings.

Site staff or a sealant 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. For that reason, many FMs and contractors use a sealant specialist from the outset.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Keeping the joints sound

After handover, a little attention goes a long way:

  • Keep racking legs and heavy point loads off floor joints
  • Act on the first tear or lifting edge rather than waiting
  • Reopen bays and walkways only after the stated cure time
  • Inspect exposed joints once the cold weather has passed

Add every elevation, deck and floor joint to your inspection round. A periodic look picks up tears and lifting before water gets in and long before edges start to break. Should you spot a problem, you can call the office on 01277 525 020 or email us and send a picture.

External wall joints that fail let rain into the masonry and cavity. The first sign is often a damp patch indoors, well after the seal first opened. Resealing promptly prevents internal damage.

How a job runs

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. If you have more than one building in Walton-on-Thames, they can often be done on the same visit, with one quote covering them. Tell us when the building is open and we’ll plan to suit.

  1. We assess the joints on site or from photos, noting widths and how each has failed.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  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. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Getting the site ready

  • Tell staff and tenants when we will be in
  • Have the specification and drawings to hand
  • Arrange parking or a loading space

Getting a fixed quote

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
