Expansion joint sealing for commercial buildings in South Ambersham

The seal is what lets a movement joint do its job. Once it fails, water, grit and debris get in. Resealing at the first signs of failure is far cheaper than repairing the material either side. We work on podiums and floor movement joints, blockwork control joints and car park decks and ramps, and the failures we’re asked to look at most are joints where the bead has lost adhesion and spalled or broken joint edges in floors and decks. Whoever orders the work in South Ambersham, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Smaller community and commercial buildings around South Ambersham have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.

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 the job involves on each surface

Internal floor movement joints

Floor joints include saw-cut joints and construction joints. Trafficked floor joints often get a semi-rigid filler, with a flexible sealant where movement is larger.

Car park decks and ramps

Car park joints are some of the hardest-working joints in any building. A trafficable sealant suited to the movement goes in.

FAQs: South Ambersham

Can you work at a site such as Holmbush Industrial Estate, by South Ambersham?

Yes, sites like Holmbush Industrial Estate are within our area, along with the rest of South Ambersham. A few photographs and the unit address let us price the work.

Is South Ambersham off your patch?

Not at all. South Ambersham is within our area. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

What causes movement joint sealant to fail?

Adhesion failure, cohesive failure, edge breakdown and UV ageing account for most cases. Working out the cause comes first since each needs a different fix.

Who decides which product is used?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.

What sets the cost

Your fixed quote is built from the real scope. It allows for:

  • Site requirements such as inductions and permits
  • How accessible the joints are
  • Whether old sealant has to be cut out first
  • Phasing around occupants

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.

Sending details for a quote

The more we know, the firmer the quote. Helpful details to send:

  • Your programme or deadline
  • How the joints are reached, and at what height
  • Rough lengths or quantities, or drawings if you have them
  • The type of building and who uses it

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

Expansion joint sealing in South Ambersham: the local picture

South Ambersham is about 44 miles from central London. The roads out of London are lined with trade parks and distribution sheds. Two named trading, business or retail sites lie within about 3 miles of South Ambersham. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.

Phasing is what makes joint work possible on busy sites such as Midhurst Business Centre (2.4 miles west of South Ambersham): one bay, aisle or car park row at a time. Hospitals like Midhurst Community Hospital (to the north-west of South Ambersham) have multi-storey or surface car parks whose joints carry vehicles round the clock. For a school such as Midhurst Rother College, playground and building joints can be done in the holidays.

South Ambersham is about 10 miles north of Chichester, in West Sussex. We send applicators to South Ambersham for movement joints. Across West Sussex, 373 places are covered, including South Ambersham. Portsmouth is covered too, some 20 miles away.

Work for main contractors and building owners

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

When something else is needed

Being straight saves everyone time. Fresh joints won’t solve:

  • Proprietary pre-formed expansion joint systems
  • Joints too narrow for the movement, which need redesigning by the engineer
  • Broken or spalled joint edges, which need repairing before any sealant goes in

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

Where we work in South Ambersham

  • Cladding panel joints
  • Brickwork movement joints
  • Car park decks and ramps
  • Blockwork control joints

What happens if it’s left?

Leaving a failed movement joint rarely stays a small problem. Grit and water fill the gap and the material either side breaks up. Acting at the first split keeps the cost down. Converted and older buildings near places like South Ambersham tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For a building around South Ambersham, 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. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. We strip out the old seal and prepare the faces, 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. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

Getting the site ready

  • Clear stock, furniture or equipment away from the joints
  • Send any specification or drawings in advance
  • Point out parking and an unloading spot
