Expansion joint sealing for businesses in Shalden Green

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

How we handle expansion joint sealing in Shalden Green

The seal is what lets a movement joint do its job. Once it fails, water, grit and debris get in. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. If you are dealing with brittle, chalky sealant on external joints and arrises breaking up along floor joints, we can help. A specialist sealant contractor works differently from a general builder: on jobs in Shalden Green, preparation and product choice get the time they need.

Jobs around smaller places like Shalden Green are planned so the whole job is done in one visit. Tell us the joint widths if you can, and what drives or walks over them.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

How the quote is worked out

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • Specialist products, such as fire-rated or hygienic sealants
  • Any access equipment needed
  • The site’s rules and procedures
  • Joint width, depth and condition

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.

Before you send an enquiry

The more we know, the firmer the quote. When you get in touch, include:

  • Any specification or named product
  • What the building is and how it’s used
  • Clear photographs of the problem areas
  • The postcode of the building

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

When something else is needed

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Crumbling edges that would give a new bead nothing sound to grip
  • Waterproofing layers buried beneath the sealant
  • Changing the joint layout or spacing of a structure

If in doubt, call the office on 01277 525 020 or email the details over and we will say what we think before you book.

Do you need expansion joint sealing in Shalden Green?

Three-sided adhesion is a common cause of early failure. Sealant fixed to the base and sides can’t flex, so it tears, which is why depth control matters.

Any of the following is a good reason to get the joints checked over:

  • Joints packed with grit and debris
  • Water dripping through deck or ramp joints
  • Weathered movement joint sealant that no longer flexes
  • Damp inside where a wall movement joint has failed

A healthcare site such as Alton Community Hospital (to the south of Shalden Green) depends on car parks, ramps and service yards whose joints take traffic all day.

  • Proof of insurance
  • The named product and why it was chosen

Our contractor checklist

Doing it in-house

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Common questions from Shalden Green clients

Can you work on a hospital site such as Alton Community Hospital?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

Does your area include sites such as Kerridge Industrial Estate, near Shalden Green?

Yes, sites like Kerridge Industrial Estate are within our area, along with the rest of Shalden Green. Send details of the unit and the work through our quote form for a quick quote.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Are expansion joints and movement joints the same thing?

Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Many people call it an expansion joint, and either way it needs a sound seal.

What guarantee do you give on joint sealing?

Each job is backed by a 12-month guarantee on the workmanship. Damage from later works or traffic loads outside the joint’s design isn’t a workmanship fault.

Can you seal car park deck joints?

Yes. Tyre loads, grit and de-icing salts make these some of the hardest joints to keep sealed.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Expansion joint sealing around Shalden Green: points for this area

Shalden Green lies roughly 45 miles out from central London. The roads out of London are lined with trade parks and distribution sheds, and their floor joints take forklift and pallet-truck traffic all day. Shalden Green is in the South East, one of the UK’s drier regions. Even so, yard and car park joints are only sealed when they’re dry and clean, while winter salting gets into any joint left open.

For an occupier at a site such as Kerridge Industrial Estate, 2.8 miles south-east of Shalden Green, the joints at loading doors and dock levellers normally see the hardest wear.

Our process

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. For work around Shalden Green, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. We look at the joints, their width and how they’ve failed.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. Old sealant and filler are cut out and the joint faces cleaned back to sound material.
  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. Each joint is inspected and handed over with our 12-month guarantee.

What we need from you

  • Point out any areas we must not close
  • For older buildings, check the asbestos register before work
  • Let us know about inductions and permits

Why it’s worth doing now in Shalden Green

A torn seal left alone typically gets worse. Grit and water fill the gap and the material either side breaks up. Resealing early keeps the work to sealant. Halls, stores and units around places like Shalden Green may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.
