Common questions from South Ambersham clients

Is South Ambersham too small for you to travel to?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Will you take on work at estates like Holmbush Industrial Estate, close to South Ambersham?

Yes. Estates, retail parks and business parks around South Ambersham, Holmbush Industrial Estate among them, are all within reach. 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 work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

Why has the filler pulled away from one side?

Separation typically comes from slab shrinkage, poor preparation or the wrong product. We diagnose the cause before suggesting a fix.

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Does the weather affect the work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Is colour matching possible?

That depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

How we handle floor joint sealing in South Ambersham

A working floor can rarely be closed for days on end, so the work is split into zones and treated one area at a time. Share your site hours and access windows and the programme is built around them, with goods still moving in the areas we aren’t in. Site teams most often ask us about old filler gone hard, cracked or loose and loading bay joints breaking down, across retail and showroom floors, joints along racking aisles and loading bays. Whether you call it commercial sealant work, mastic application or joint sealing, the work in South Ambersham is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around smaller places such as South Ambersham, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

A 12-month guarantee applies to all our work. If an installation problem shows up, speak to us on 01277 525 020 or email us and we’ll arrange a return visit.

When it isn’t the sealant

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

  • A floor that rocks at the joints, which needs a structural fix
  • Structural cracking in the slab
  • Spalled arrises, which need an edge repair first

If you are not sure, just call the office on 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.

Surfaces we seal

  • Loading bays
  • Saw-cut induced joints
  • Forklift and pallet-truck routes
  • Construction joints
  • Retail and showroom floors
  • Joints along racking aisles

Leave it or put it right?

Every jolt over a broken joint passes into the truck, the load and the driver. That means extra wear on wheels and a rougher ride for staff, adding costs nobody plans for. A properly filled joint smooths the route. 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.

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.

Maintenance after handover

Regular inspection catches problems early. Specifically:

  • Walk the main routes and inspect joint lines on a regular cycle
  • Let us know what the floor is cleaned with
  • Start with the dock areas, where joints fail soonest
  • Clear packed debris from open joints regularly

On younger slabs, a fine line can open down one side of a filled joint as the concrete keeps shrinking. That is common and is normally dealt with by topping up once the slab has settled down.

Grit in an open joint does damage every time a wheel crosses it. Getting it filled stops the damage while it is still a straightforward job.

Slabs, ramps and loading bays in South Ambersham

Less than 3 miles from South Ambersham there are two named estates and business parks. Their warehouses, yards and car parks are exactly where joints take the most punishment. South Ambersham is about 44 miles from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors.

In a school such as Midhurst Rother College, movement joints in brick, block and hall floors tend to be forgotten until they leak. 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.

Our process

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. For a building around South Ambersham, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. Each area is assessed for joint width, arris damage and the wheels that cross it.
  2. You get a fixed quote with the product and the phasing set out.
  3. Each joint is cleared of old fill and dirt and taken back to clean, sound edges.
  4. We vacuum each run and prime it if the chosen product requires a primer.
  5. Filler or sealant goes in to the right depth and is finished flush with the slab.
  6. Each phase reopens when the product is ready for wheels, then we start the next.

What we need from you

  • Send asbestos survey details if the building is pre-2000
  • Tell staff and tenants when we’ll be in
  • Agree which areas must stay open

Different surfaces, different methods

Semi-rigid joint fillers

On industrial routes, a semi-rigid filler is often the right choice. We place them to depth and trim them level with the slab.

Forklift and pallet-truck routes

Main aisles and cross routes carry the most wheel movements, so their joints wear fastest. A semi-rigid filler is common here because it supports the arrises under hard wheels.

Common problems we fix in South Ambersham

Floor joints collect dust, oil, curing compound and cleaning residue. If the faces aren’t taken back to clean concrete first, the new material simply lifts out.

Site and facilities staff are often the first to spot these:

  • Joint fill separating from the concrete
  • Grimy joint lines spoiling a showroom floor
  • Loading bay joints breaking down
  • Soft sealant dragged out of trafficked joints

Hospital campuses such as Midhurst Community Hospital (2 miles north-west of South Ambersham) grow in stages, leaving movement joints wherever new blocks meet old.
