Expansion joint sealing for commercial buildings in Ash

A movement joint only works while its seal does. When the sealant splits or lets go, the gap fills with dirt and water. 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 debris jammed in movement joints, we can put it right. Most enquiries from Ash start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around places the size of Ash, joints that need sealing tend to be in rural business units, farm buildings put to commercial use, schools and community buildings. Concrete floors and yards in these buildings move and crack like any others.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Why it’s worth doing now in Ash

Resealing is usually the answer, not replacing the element. Where the edges are sound, cutting out and resealing is enough. If the edges have broken up, we will tell you they need repairing first. In a smaller place such as Ash, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Why clients in Ash choose us

  • A range of standard colours, depending on the product
  • Our applicators hold CSCS cards
  • One phone line for London, the South East and Scotland
  • A Constructionline member, so easy to vet

Take a look at our cost guide and how we’re accredited.

Building owners, agents and FMs in Ash

CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.

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.

Doing it in-house

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Quoting for work in Ash

A fixed quote reflects the actual work. It takes account of:

  • Any access equipment needed
  • The size and state of each joint
  • Specialist products, such as fire-rated or hygienic sealants
  • The total length or number of joints

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Sending details for a quote

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

  • Clear photos of the problem areas
  • Any specification or named product
  • The site address and postcode
  • How the joints are reached, and at what height

Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings that you can work with. If you have questions first, ring 01277 525 020 or email drawings and photos.

On site: what to expect

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Work in places the size of Ash is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  2. We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Any broken arrises or friable edges are flagged before work goes further.
  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.

What we need from you

  • Send any specification or drawings in advance
  • Point out parking and an unloading spot
  • Point out any areas we must not close

Quotes

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Advice

FAQs: Ash

Can you take on a job at a hospital such as Guildford Hospital?

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.

Is Ash too small for you to travel to?

No. Small places get the same service as large ones. We work across Greater London and the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can the building stay open while you work?

Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.

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

It’s a deliberate gap that lets the structure move without cracking. Many people call it an expansion joint and both need a flexible seal.

When is resealing likely to be due?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

What happens if it rains on the day?

Sealant needs a dry joint and a temperature within the product’s range. Cold, damp or frosty mornings can stop work outside.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

When something else is needed

Honesty saves time and money. Fresh joints won’t solve:

  • Crumbling edges that would give a new bead nothing sound to grip
  • Movement on a scale no sealant is meant to absorb
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)

If you’re not sure, just call 01277 525 020 or use the quote form and we will give you a straight answer before you book.
