Expansion joint sealing for businesses in Sullington

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

Diagnose, treat, sign off

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. If others near Sullington need work, visits can be combined. A fixed quote is given before anything starts.

  1. We assess the joints on site or from photos, noting widths and how each has failed.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Before we start on site

  • Tell us your opening times and when work is allowed
  • Let us know about inductions and permits
  • Agree which areas must stay open

Getting a fixed quote

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, call the office on 01277 525 020 or use the quote form.

How we handle expansion joint sealing in Sullington

If you need expansion joint sealing in Sullington, start with photographs and joint lengths. We’ll come and look where photographs don’t show enough. To discuss the joints first, speak to us on 01277 525 020 or email the details over. We work on precast concrete panel joints, blockwork control joints and cladding panel joints, and what we are called in for most is damp inside where a wall movement joint has failed and chipped joint edges on forklift routes. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Sullington, preparation and product choice get the time they need.

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

Work we carry out in West Sussex comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or send photos by email and we will arrange a return visit.

Aftercare for building managers

To get the most from the new sealant:

  • Record the sealant used and the date in the O&M file
  • Plan racking layouts so feet don’t land on a joint
  • Keep stones and debris out of open joint lines
  • Brief car park operatives to protect joint lines during winter clearance

Our workmanship on movement joints carries a 12-month guarantee. Record which product went into which joints in the building file.

Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint. Catching it early keeps the water outside.

What sets the cost

Each job is priced on its own details. The things that drive the figure:

  • Backing rod, priming and other preparation
  • Access and working height
  • The total length or number of joints
  • How much existing material needs removing

The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.

What we need to price the job

However big the job, these details speed things up:

  • Approximate linear metres or a joint schedule
  • Clear photos of the problem areas
  • How the joints are reached, and at what height
  • What the building is and how it’s used

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Should maintenance staff do it?

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

What the job involves on each surface

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 with bays done in phases so the car park keeps running.

Brickwork and blockwork joints

Brick and block edges need careful preparation. We clean them back to sound material and prime where the manufacturer specifies.

Expansion joint sealing around Sullington: what changes locally

The 3 miles around Sullington take in at least three named trading estates, business parks or retail parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. Sullington is in the South East, one of the UK’s drier regions. External slab and deck joints still need a dry, clean joint to seal, and gritting in cold spells finds its way into open joints.

Business parks such as Rock Business Park (to the east of Sullington) have car parks, paved areas and long brick and panel elevations, all with movement joints. Another example is Wiston Business Park, 1.8 miles north-east of Sullington, where floors and yards would be done in stages around the occupiers. Schools like Thakeham Primary School often have long brick elevations with movement joints that age quietly.

Sullington is about 6 miles north of Worthing, in West Sussex. We send applicators to Sullington for movement joints. We work across 373 places in West Sussex, from busy centres to rural villages. For work in that direction, see our Brighton page (14 miles or so).

Work on movement joints is covered throughout RH20, whatever the building. Just outside Sullington, we also work in Storrington (1 mile north-west), Heath Common (1 mile north-east), Washington (1 mile east), Rock (1 mile east) and Cootham (2 miles north-west). Nearby towns on our patch include Horsham (12 miles north-east), Worthing (6 miles south), Bognor Regis (14 miles south-west), Burgess Hill (14 miles east), Littlehampton (8 miles south-west) and Shoreham-by-Sea (9 miles south-east).

Landmarks near Sullington

Locally, jobs take us to sites close to The Anchor Inn and Rydon Community College and the streets around them. For rail, the closest station is Amberley station, roughly 4.7 miles west of the centre. Well-known places in the area include The Storrington And District Museum (0.7 miles north-west) and Amberley Castle (4.5 miles west). For a walk, there’s Amberley Wildbrooks RSPB Reserve and Chanctonbury Hill.

Your questions answered

Do we have to stop operations in Sullington while the joints are sealed?

Rarely. Work is phased around your operations. We agree the sequence and timings with you before we start.

Do you cover business parks and estates near Sullington, such as Rock Business Park?

Yes, sites like Rock Business Park are within our area, along with the rest of Sullington. To start, just ring 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

Can you seal joints in cold or wet weather?

A wet joint can’t be sealed properly so we’d rather rearrange than seal in the rain. The work is simply moved to the next suitable day.

How long before the joints can be used?

We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Which product is best for expansion joints?

We choose a sealant with a movement capability that suits the joint. Hybrid or MS polymer products suit some mixed-material joints.

Do you offer coloured sealant?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.

Honest limits

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • A joint that has to be widened or re-detailed before it can work
  • Movement on a scale no sealant is meant to absorb

If you’re not sure, just give us a call on 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.
