Expansion joint sealing near Keeres Green

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

Expansion joint sealing in Keeres Green, done properly

For movement joints in Keeres Green, photographs and approximate lengths are the best start. We’ll come and look where photographs don’t show enough. To discuss the joints first, speak to us on 01277 525 020 or email the details over. Most enquiries involve sealant peeling off one face of the joint and debris jammed in movement joints, across car park decks and ramps, cladding panel joints and podiums and floor movement joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Keeres Green, preparation and product choice get the time they need.

Smaller community and commercial buildings around Keeres Green have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Common questions from Keeres Green clients

Does a site in Keeres Green have to shut while its joints are sealed?

Usually not: we work in sections and hand each one back once it has cured. Tell us which hours and entrances we can use and we’ll plan from there.

Is a smaller place like Keeres Green outside your area?

Not at all. Keeres Green is within our area. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Do you need to see the site first?

It depends on the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.

Who decides which product is used?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Is it fine to apply new sealant on top of old?

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

Do you take on multi-site work?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

Why act early in Keeres Green

Some quotes just add sealant over the old bead. A bead laid on top of the failed one neither grips nor flexes properly, so it fails quickly. Full removal and preparation is in every quote. For buildings around smaller places like Keeres Green, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Why us?

  • Colour agreed before work starts
  • Matching to RAL references, product permitting
  • Health and safety: CHAS accredited
  • Sealing commercial buildings since 2005

Looking after the joints

Once the work is signed off, these steps help:

  • Record the sealant used and the date in the O&M file
  • Reopen bays and walkways only after the stated cure time
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Plan racking layouts so feet don’t land on a joint

Debris does more harm to joint sealant than most people realise. Grit trodden or driven into the joint works at the surface until it tears, especially on car park decks and warehouse floors. Regular sweeping keeps joint lines clear.

External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint. Resealing promptly prevents internal damage.

Site staff or a sealant specialist?

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

From enquiry to sign-off

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work normally 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. Smaller jobs around Keeres Green can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. We start with photos, approximate lengths and any drawings, visiting where needed.
  2. Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
  3. Old sealant and debris are cut out of every joint.
  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.

How the quote is worked out

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • The product specified
  • Working within restricted access windows
  • How much existing material needs removing
  • Induction, permit and paperwork requirements

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

What we need to price the job

We can often quote from photographs and a few details. Please tell us:

  • Asbestos survey details if the building is older
  • Any dates the work must fit around
  • The product your specification calls for
  • Clear photographs of the problem areas

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call 01277 525 020 or email the details over.

  • Broken or spalled joint edges, which need repairing before any sealant goes in

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