How we handle expansion joint sealing in Sompting
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 is tooled so it grips the two faces alone. We work on car park decks and ramps, podiums and floor movement joints and brickwork movement joints, and the usual reasons a site gets in touch are chipped joint edges on forklift routes and layers of sealant in a movement joint. Searching for sealant specialists in Sompting? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Small units near places like Sompting are often converted farm buildings with new concrete floors. Joints in those slabs need a product suited to whatever runs over them, from pallet trucks to foot traffic.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Why deal with it now?
On a car park, resealing joints in phases keeps the deck open. Work can be planned so parts of the deck stay open. We agree phasing with you before work starts. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.
We don’t publish prices, since every building and every scope is different. Call for a quote.

Expansion joint sealing around Sompting: how the place shapes the job
Sompting sits close to the coast, within about 2 miles. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, and edges left open tend to break up faster. Sompting lies roughly 47 miles out from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital.
For an estate such as Worthing Hospital, which lies south-west of Sompting, the joints in ramps, decks and long building elevations all need attention over time. At places like Lancing Business Park (0.7 miles south of Sompting), joints are sealed a section at a time so operations carry on.
Sompting is about 3 miles east of Worthing, in West Sussex. Across the BN15 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. 373 places across West Sussex fall within our area, including Sompting. We also cover Brighton, around 9 miles from Sompting.

For managing agents and facilities managers
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Sompting can sit alongside others in a wider programme.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
Questions we are asked in Sompting
Can you work on a hospital site such as Worthing Hospital?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Does the sea air around Sompting change the choice of sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
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.
Do you need to see the site first?
Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.
Do you take on small jobs?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
How do we ask for a quote?
The quote form is the simplest route, though you can also speak to us on 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
What affects the price in Sompting
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- The product specified
- Distance, for remote addresses
- The total length or number of joints
- How much existing material needs removing
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
What to include in your enquiry
Good information means a firmer quote. When you get in touch, include:
- The site address and postcode
- The type of building and who uses it
- Any dates the work must fit around
- The product your specification calls for
Need a figure for a tender or a budget? We’ll quote against your scope and drawings that you can work with. For a chat about it beforehand, give us a call on 01277 525 020 or email us.

Our process
Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. Several jobs near Sompting can be grouped on one trip. Tell us your site hours and we’ll plan around them.
- First, the joints are inspected for width, movement and the type of failure.
- A fixed quote follows, naming the sealant and its movement class.
- We strip out the old seal and prepare the faces.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- Finished joints are checked and backed by our 12-month guarantee.
What we need from you
- Tell staff and tenants when we’ll be in
- Share the asbestos register for older buildings
- Confirm the product named in the specification
Request a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.
Related advice
When to call us in Sompting
Sealant peeling cleanly off one side is an adhesion failure. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons, and it’s common on joints sealed in a hurry.
Most enquiries start with something like this:
- Expansion joints split through the centre of the bead
- Damp inside where a wall movement joint has failed
- Expansion joints filled with dirt and stones
- Brittle, chalky sealant on external joints
Business parks such as Rectory Farm Road Business Park, less than half a mile to the north of Sompting, have car parks, paved areas and long brick and panel elevations, all with movement joints.
Questions to ask before you book
- Health and safety accreditation such as CHAS
- Is the sealant right for the movement and the substrate?
- Whether their applicators hold CSCS cards
- Proof of insurance
Looking after the joints
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Reopen bays and walkways only after the stated cure time
- Avoid parking heavy plant or pallets on joint lines
- Record the sealant used and the date in the O&M file
- Inspect movement joints alongside other routine building checks
Every joint we seal is backed by a 12-month guarantee on workmanship. Record which product went into which joints in the building file, so the next reseal starts with the facts.
On a multi-storey car park, a failed joint typically shows up as a leak onto the deck underneath. Salty water dripping through stains soffits and lands on parked vehicles. Sealing the joint promptly stops it at source.
