Need expansion joint sealing in Bedmond?

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

Aftercare for building managers

To get the most from the new sealant:

  • Check joints after long freezing spells
  • Keep product details with the building records for the next reseal
  • Clear dirt from joint lines during routine cleaning
  • Reopen bays and walkways only after the stated cure time

Every joint we seal is backed by a 12-month guarantee on workmanship. Keep the handover details, product and date with your O&M records so future maintenance isn’t guesswork.

Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint, well after the seal first opened. Catching it early keeps the water outside.

About our expansion joint sealing in Bedmond

Joints in car park decks and ramps are among the hardest-working in any building. Wheel loads, grit and de-icing salts attack the seal and the concrete either side; water dripping through to the deck below is often the first sign. A sealant suited to traffic and the expected movement goes in, phasing bays so the car park can stay in use. We work on precast concrete panel joints, brickwork movement joints and podiums and floor movement joints, and what we are called in for most is sealant pulling off the joint face and layers of sealant in a movement joint. Most enquiries from Bedmond 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.

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

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

How a job runs

Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. Rural sites near Bedmond may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. We compare each joint’s width with the movement and the sealant’s capability.
  3. Old sealant and debris are cut out of every joint.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

What we need from you

  • For older buildings, check the asbestos register before work
  • Send any specification or drawings in advance

What sets the cost

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • Whether old sealant has to be cut out first
  • The site’s rules and procedures
  • The product specified
  • Access and working height

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.

Sending details for a quote

However big the job, these details speed things up:

  • Asbestos survey details if the building is older
  • Clear photos of the problem areas
  • When you need the work done
  • Specification clauses that apply

For a fixed quote, call the office on 01277 525 020 or email a schedule or drawings with the site address and an outline of the work. You can also send details through our quote form.

FAQs: Bedmond

Can you work at a site such as Kings Park Industrial Estate, by Bedmond?

Yes. Our area takes in Bedmond and its surroundings, with estates and business parks such as Kings Park Industrial Estate included. Photos and a short description are enough for a first look.

Is Bedmond too far out for you?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

How long do sealant joints last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Is movement joint sealing guaranteed?

A 12-month guarantee covers our workmanship, and we are fully insured for public liability. Regular sweeping and inspection help the joints last.

Do the joint edges need to be sound before sealing?

The edges have to be sound. If they’re damaged, we’ll say so before any sealing so you are not paying for a bead that won’t hold.

Does weather matter for sealant work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

What we can’t put right

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Damaged metal nosings or cover plates over a joint
  • Waterproofing layers buried beneath the sealant
  • Cracking or settlement that calls for an engineer’s assessment

Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we’ll tell you honestly.

Joints and surfaces we work on

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

When to call us in Bedmond

Sometimes the sealant holds but the substrate breaks away. If the edge of the joint is friable, the bond fails with it so edge repair has to come before resealing.

Look out for the following:

  • Expansion joints split through the centre of the bead
  • Rain penetration at brick or block movement joints
  • Car park joints leaking onto vehicles below
  • Weathered movement joint sealant that no longer flexes

Phasing is what makes joint work possible on busy sites such as Hill Farm Avenue Industrial Estate (1.8 miles south of Bedmond): one bay, aisle or car park row at a time.

  • Their pre-qualification and accreditations

Our contractor checklist

Where floor joints take the most wear near Bedmond

The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and where de-icing salt is spread in winter, open joints let it in. At least three named trading, business or retail sites lie within about 3 miles of Bedmond. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.

In a school such as Bedmond Academy, movement joints in brick, block and hall floors tend to be forgotten until they leak. For an occupier at a site such as Kings Park Industrial Estate, 1.4 miles to the west of Bedmond, the joints at loading doors and dock levellers usually see the hardest wear.

Bedmond is about 3 miles south-east of Hemel Hempstead, in Hertfordshire. We send applicators to Bedmond for movement joints, handled exactly as we handle every other area. Across Hertfordshire, 371 places are covered, Bedmond among them. London is covered too, around 20 miles from Bedmond.
