Expansion joint sealing in Greywell

Long runs of brick or block have movement joints built in, and they’re easy to miss until the sealant fails. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled, primed where the manufacturer specifies. We work on brickwork movement joints, car park decks and ramps and blockwork control joints, and the usual reasons a site gets in touch are leaks through car park deck joints onto the level below and arrises breaking up along floor joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Greywell, preparation and product choice get the time they need.

Jobs around smaller places like Greywell are planned so the whole job is done in one visit, with the right materials on hand. Note joint widths and the traffic that uses them, and we’ll take it from there.

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

For managing agents and facilities managers

If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Aftercare for building managers

Regular inspection catches problems early. In particular:

  • Keep racking legs and heavy point loads off floor joints
  • Act on the first tear or lifting edge rather than waiting
  • Keep scrapers and ploughs from dragging across joint sealant
  • Reopen bays and walkways only after the stated cure time

Grit is the slow enemy of a joint seal. Grit trodden or driven into the joint works at the surface until it tears. A routine sweep is the simplest protection.

Once debris packs a failed joint, the structure has nowhere to expand. The arrises crack and break away under the load, turning a sealant job into a repair job. Keeping the seal sound avoids all of that.

From enquiry to sign-off

Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. For a building around Greywell, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  2. Joint widths and expected movement are checked against what the sealant can take and tell you if the design looks wrong for the movement.
  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. Each area is handed back after its cure time, under our 12-month guarantee.

What we need from you

  • Share your working hours and any access restrictions
  • Tell us which areas need to stay in use
  • Let building users know which areas are affected

Getting a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.

Doing it in-house

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

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

What sealant work can’t fix

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:

  • Movement on a scale no sealant is meant to absorb
  • Concrete or masonry repairs along the arrises
  • Joints too narrow for the movement, which need redesigning by the engineer

Not sure which it is? You can speak to us on 01277 525 020 or email drawings and photos and we’ll tell you honestly.

Joints and surfaces we work on

  • Podiums and floor movement joints
  • Brickwork movement joints

Questions we are asked in Greywell

Do you take on work at healthcare sites like Fleet Community Hospital?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

Do you cover business parks and estates near Greywell, such as Murrell Green Business Park?

Yes. Our area takes in Greywell and its surroundings, with estates and business parks such as Murrell Green Business Park included. To start, just give us a call on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

How do I request a quote?

You can use the quote form on this site; alternatively, ring 01277 525 020 or email a schedule or drawings. Photos, drawings or a joint schedule help us quote quickly.

Do you guarantee expansion joint work?

The 12-month guarantee applies to the workmanship. Tell us straight away if a joint we sealed gives trouble in that time.

Can a joint be sealed if the edges are broken?

Sound edges are essential. If they’re damaged, we’ll say so before any sealing so you are not paying for a bead that won’t hold.

Can you seal car park deck joints?

Yes. We use a sealant designed for wheel loads and the expected movement, and phased work can be planned so parts of the car park stay in use.

Do you need expansion joint sealing in Greywell?

When the movement exceeds the sealant’s capability, the bead tears. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. The same product in the same joint tends to fail again.

Things that normally lead to an enquiry:

  • Torn sealant in brick or block movement joints
  • Damp inside where a wall movement joint has failed
  • Water dripping through deck or ramp joints
  • Debris jammed in movement joints

Schools such as Robert May's School have movement joints in their walls and floors that are easy to overlook.

  • What site paperwork they can supply
  • How the existing material will be dealt with
  • Are they CHAS accredited or on Constructionline?
