Expansion joint sealing near Hammer Bottom

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

When to call us in Hammer Bottom

Sometimes the sealant holds but the substrate breaks away. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip so edge repair has to come before resealing.

If one of these sounds familiar, it’s time for a closer look:

  • Sealant pulling off the joint face
  • Previous reseals laid over old sealant
  • Expansion joints split through the centre of the bead
  • Arrises breaking up along floor joints

Phasing is what makes joint work possible on busy sites such as Unicorn Trading Estate (1.9 miles east of Hammer Bottom): one bay, aisle or car park row at a time.

Questions to ask before you book

  • Whether their applicators hold CSCS cards
  • Will failed sealant be removed rather than covered?
  • How long is the guarantee, and what does it include?
  • Will RAMS and insurance details be available?

How to choose a sealant contractor

Expansion joint sealing for commercial buildings in Hammer Bottom

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Without a sound filler, joint edges chip and spall under load so the product has to suit both the traffic and the movement. We’ll tell you if the edges need repairing before sealing and phasing can keep areas working. The enquiries we see most involve arrises breaking up along floor joints and hardened, cracked sealant on exposed facades, across podiums and floor movement joints, cladding panel joints and blockwork control joints. Whoever orders the work in Hammer Bottom, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

Smaller community and commercial buildings around Hammer Bottom have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Hammer Bottom: questions and answers

Does your area include sites such as Kings Road Industrial Estate, near Hammer Bottom?

Yes. We cover Hammer Bottom and the area around it, including industrial estates, business parks and retail parks such as Kings Road Industrial Estate. A few photographs and the unit address let us price the work.

Is hospital work, at somewhere like Holy Cross Hospital, something you do?

Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

What hours do you work?

Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

Is movement joint sealing guaranteed?

The workmanship is guaranteed for 12 months from sign-off and we hold public liability insurance. Keeping joints clear of debris helps them last.

Are you CHAS accredited and on Constructionline?

Can you work to our specification?

Building owners, agents and FMs in Hammer Bottom

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. Several sites can go on one quote, which keeps the paperwork simple.

What we can’t put right

Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:

  • Joints too narrow for the movement, which need redesigning by the engineer
  • Proprietary pre-formed expansion joint systems
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)

Not sure which it is? You can give us a call on 01277 525 020 or send details through our quote form and we will tell you honestly.

Surfaces we seal

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

Our process

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. Jobs in and around smaller places like Hammer Bottom are normally planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Before we start on site

  • Let us know about inductions and permits
  • Tell us which areas need to stay in use
  • Send asbestos survey details if the building is pre-2000

Surface by surface

Brickwork and blockwork joints

Long brick and block elevations have movement joints at intervals. We use a sealant rated for the movement, normally low-modulus, with backing rod setting the depth.

Joints between different materials

Some mixed-material joints suit a hybrid sealant. We pick the product for the materials and the movement.

How the quote is worked out

These are the things that shape the price:

  • Specialist products, such as fire-rated or hygienic sealants
  • Access and working height
  • Distance, for remote addresses
  • Backing rod, priming and other preparation

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

What we need to price the job

The more we know, the firmer the quote. Helpful details to send:

  • The site address and postcode
  • Anything awkward about access or site hours
  • Any dates the work must fit around
  • A wide shot and a close-up of the area

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. If you have questions first, speak to us on 01277 525 020 or email the details over.
