Expansion joint sealing across Lumley

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Work for main contractors and building owners

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

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Expansion joint sealing for commercial buildings in Lumley

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Unsupported edges break up under wheels so the product has to suit both the traffic and the movement. We will tell you if the edges need repairing before sealing, and phased work keeps areas in use. If you are dealing with arrises breaking up along floor joints and rain penetration at brick or block movement joints, we can help. Searching for sealant specialists in Lumley? We have been sealing commercial buildings since 2005.

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

We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

What we can’t put right

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • A joint that has to be widened or re-detailed before it can work
  • Concrete or masonry repairs along the arrises
  • Proprietary pre-formed expansion joint systems

Not sure which it is? You can ring 01277 525 020 or email the details over and we will tell you honestly.

Joints and surfaces we work on

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

Aftercare for building managers

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Look over external and deck joints after a hard winter
  • Treat a small split as a warning, not a cosmetic issue
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Keep scrapers and ploughs from dragging across joint sealant

Snow ploughs and scrapers catch on joint lines. Lifting the blade at each joint avoids tearing the bead and a look at the joints after winter catches any damage.

A failed deck joint lets water straight through to the level below. That water often carries de-icing salts with it and it can affect the structure over time. Resealing early limits the damage.

Traffic, movement and joints around Lumley

Lumley is within about 1 mile of the coast. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, so it pays to keep them sealed. At about 58 miles from central London, Lumley is within reach of the capital. The South East has large numbers of industrial estates and warehouses along the motorway corridors.

Schools like St James Church of England Controlled Primary School often have long brick elevations with movement joints that age quietly. Hospitals like Spire Hospital Portsmouth (to the north-west of Lumley) have multi-storey or surface car parks whose joints carry vehicles round the clock.

Lumley is about 1 mile east of Emsworth, in West Sussex. Commercial clients in Lumley use us for work on movement joints, as part of our coverage of West Sussex. 373 places across West Sussex fall within our area, Lumley among them. For work in that direction, see our Portsmouth page, about 7 miles away.

FAQs: Lumley

Do you cover business parks and estates near Lumley, such as Central Retail Park?

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

Our building in Lumley is near the coast: does that change the sealant?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.

Can you work while the building is occupied?

Yes, with some planning. Tell us your site hours and access windows and we will plan around them.

How much does the work cost?

Every job gets its own fixed quote. To get one, ring 01277 525 020 or send photos by email.

How do we ask for a quote?

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

Do you reseal car park expansion joints?

Yes. Let us know the opening hours and which levels or bays have to stay available and we will plan around them.

Can you send site paperwork?

Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.

How a job runs

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before we move to the next. If others near Lumley need work, visits can be combined. A fixed quote is given before anything starts.

  1. Photos, joint lengths and drawings come to us, or we visit.
  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. Edges are checked, and we tell you if any need repairing before sealing.
  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.

Preparing the site

  • Explain the parking and delivery arrangements
  • Have the specification and drawings to hand
  • Move anything stored against the joints

Request a quote

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

Do you need expansion joint sealing in Lumley?

With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Bonded on three faces, it can’t stretch evenly when the joint opens.

Any of the following is a good reason to get the joints checked over:

  • Water dripping through deck or ramp joints
  • Water getting into the wall through a failed joint
  • Joints where the bead has lost adhesion
  • New sealant over old, now failing

Across sites such as Solent Retail Park, 2.4 miles west of Lumley, floor and movement joints can be sealed in phases so units keep working.

What to look for in a quote

  • Whether primer will be used where the manufacturer specifies it
  • Will RAMS and insurance details be available?
  • Whether old or failed sealant will be cut out, not overlaid
  • Which product they’ll use, and why it suits the joint

How to choose a sealant contractor

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
