FAQs: Slindon

Does your area include sites such as Tokar Industrial Park, near Slindon?

Yes. Our area takes in Slindon and its surroundings, with estates and business parks such as Tokar Industrial Park included. To start, just call the office on 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Is Slindon too far out for you?

Not at all. Slindon is within our area. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

Which sealant will you use?

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.

Do you offer coloured sealant?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

Does the weather affect joint sealing?

Weather matters for any external joint because a damp or frozen joint won’t take a proper bond. Indoor joints can typically carry on regardless.

Can a joint be sealed if the edges are broken?

Spalled edges need repairing before a new seal will last. A bead on a broken edge soon lets go.

How we handle expansion joint sealing in Slindon

Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1 and the bead bonds to the sides, never the back. If you have damp inside where a wall movement joint has failed and movement joints with split or torn sealant, we can put it right, on blockwork control joints, podiums and floor movement joints and precast concrete panel joints alike. For commercial sealant work in Slindon, you deal with one contact from quote to sign-off, whether it’s one building or several.

In and around smaller places like Slindon, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

Commercial clients in Slindon

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.

We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.

How the job changes by surface

Joints between different materials

Different materials meeting at a joint rarely move in step. We choose a sealant that grips both faces, with primer where specified.

Brickwork and blockwork joints

A brick movement joint full of old mortar or debris can’t close. We clear the joint fully before sealing and flag any joint that seems undersized.

Slabs, ramps and loading bays in Slindon

Slindon sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, and winter de-icing salt on car parks and ramps works into any open joint. Slindon lies roughly 50 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London.

For an occupier at a site such as Tokar Industrial Park (2 miles south of Slindon), the joints at loading doors and dock levellers usually see the hardest wear. For a school such as Slindon CofE Primary School, playground and building joints can be done in the holidays. Hospitals like Arundel and District Hospital, 3 miles east of Slindon, have multi-storey or surface car parks whose joints carry vehicles round the clock.

Why it’s worth doing now in Slindon

Doing joint resealing alongside other planned works can save on access. Leaking joints need sealing now because damage continues. We can split the scope into urgent and planned. One visit to deal with every failing joint makes more sense than several trips to a place like Slindon, rather than one at a time. Photos of every joint help us quote for the whole job.

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote when you’re ready.

What you get with us

  • Workmanship guaranteed for 12 months
  • Health and safety: CHAS accredited
  • Specification-led, product-correct work
  • Failed material removed, not covered up

How a job runs

We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you. For work around Slindon, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  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. The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

Getting the site ready

Advice

What affects the price in Slindon

What shapes the price:

  • The total length or number of joints
  • Travel to remote or island sites
  • How accessible the joints are
  • How much existing material needs removing

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

What to include in your enquiry

To price the job accurately, we need to understand the site. Send us:

  • Clear photographs of the problem areas
  • Rough lengths or quantities, or drawings if you have them
  • Whether the building will be occupied during the work
  • Any specification or named product

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or call the office on 01277 525 020 or email drawings and photos if you’d rather talk the job through.

Doing it in-house

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.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
