Expansion joint sealing across Medstead

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

Expansion joint sealing in Medstead

We cover the full range of movement joints: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. The product depends on the movement, the weather and anything that runs over it and we name it in the quote. We work on podiums and floor movement joints, blockwork control joints and precast concrete panel joints, and what we’re called in for most is leaks through car park deck joints onto the level below and spalled or broken joint edges in floors and decks. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Medstead, preparation and product choice get the time they need.

Rural business units around smaller places such as Medstead often have new slabs laid inside older buildings. Joints in those slabs need a product suited to whatever runs over them, from pallet trucks to foot traffic.

A 12-month guarantee applies to all our work. Should something we installed fail, speak to us on 01277 525 020 or email a schedule or drawings and we’ll come back to it.

Common problems we fix in Medstead

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 we tell you if the edges need repairing first.

Clients typically get in touch after noticing one or more of the following:

  • Arrises breaking up along floor joints
  • Expansion joints split through the centre of the bead
  • Weathered movement joint sealant that no longer flexes
  • Previous reseals laid over old sealant

Across sites such as Lower Soldridge Business Park, 0.8 miles south-west of Medstead, floor and movement joints can be sealed in phases so units keep working.

What your quote should include

  • Will CSCS-carded applicators be on site?
  • Health and safety accreditation such as CHAS
  • The terms of the workmanship guarantee
  • Their plan for phasing and protecting the area

Choosing a commercial sealant contractor

Our process

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints, and our waste is bagged and taken away as we go. If neighbouring businesses or buildings around Medstead need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. Old sealant and filler are cut out and the joint faces cleaned back to sound material, and we tell you if any edges need repairing first.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

How the job changes by surface

Internal floor movement joints

Warehouse and retail floors have saw-cut induced joints and construction joints. A semi-rigid filler is common in trafficked industrial floors.

Car park decks and ramps

Car park joints are some of the hardest-working joints in any building. We use a sealant made for wheel loads and the expected movement.

For managing agents and facilities managers

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Doing it in-house

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Maintenance after handover

A few simple habits keep the new joints working:

  • Keep scrapers and ploughs from dragging across joint sealant
  • Plan racking layouts so feet don’t land on a joint
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Inspect exposed joints once the cold weather has passed

Movement joints belong on the planned maintenance inspection list. A periodic look picks up tears and lifting before water gets in, when they’re still cheap to deal with. If anything looks wrong, ring 01277 525 020 or send photos by email with photos.

Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort so you can prioritise and budget. We can suggest an order, worst joints first.

Questions we are asked in Medstead

Is Medstead too small for you to travel to?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

Does your area include sites such as Mansfield Business Park, near Medstead?

Yes, sites like Mansfield Business Park are within our area, along with the rest of Medstead. Send details of the unit and the work through our quote form for a quick quote.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

How do we ask for a quote?

You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or send photos by email. Include photographs or drawings if you have them.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Do the joint edges need to be sound before sealing?

Broken arrises have to be put right before resealing, and we’ll point out where that’s the case. Sealing over them leads to early failure.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Where floor joints take the most wear near Medstead

Less than 3 miles from Medstead there are at least three named estates and business parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. Medstead is in the South East, one of the UK’s drier regions. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open.

Large sites such as Alton Community Hospital (3.1 miles north-east of Medstead) have car parks, service roads and long elevations with movement joints in brick and panels. In a school such as Medstead Church of England Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.
