How we handle expansion joint sealing in Runcton
Mastic Doctor has sealed movement joints since 2005, for main contractors, FMs, managing agents and building owners. Our applicators are CSCS-carded, we’re CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. We work on blockwork control joints, car park decks and ramps and cladding panel joints, and what we are called in for most is damp inside where a wall movement joint has failed and car park joints leaking onto vehicles below. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Runcton it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around smaller places such as Runcton, 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.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Traffic, movement and joints around Runcton
Runcton is within about 3 miles of the coast. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, so a failed joint lets more in and the edges break up sooner. At about 55 miles from central London, Runcton is within reach of the capital. The South East has large numbers of industrial estates and warehouses along the motorway corridors.
Warehouse floors on estates like Quarry Lane Industrial Estate, 1.2 miles to the north-west of Runcton, carry pallet trucks and forklifts over every saw-cut joint. Schools like North Mundham Primary School often have long brick elevations with movement joints that age quietly.
Runcton is about 2 miles south-east of Chichester, in West Sussex. We cover Runcton, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across West Sussex, 373 places are covered, including Runcton. Sites around Portsmouth have their own page, about 14 miles away.

When to call us in Runcton
Repeated failure often traces back to the wrong product. A stiff or general-purpose sealant across a joint with large movement won’t cope. Movement capability is set out in BS EN ISO 11600, and specifications often refer to it.
Clients usually get in touch after noticing one or more of the following:
- Expansion joints split through the centre of the bead
- Expansion joints filled with dirt and stones
- Rain penetration at brick or block movement joints
- New sealant over old, now failing
A campus such as University of Chichester (to the east of Runcton) has long runs of movement joint in its buildings, decks and paving.

From enquiry to sign-off
Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before the next one starts. For a building around Runcton, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- We assess the joints on site or from photos, noting widths and how each has failed.
- You receive a fixed quote stating the product and the movement it is rated for.
- Where areas have to stay open, we agree a phased sequence before starting.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Before we start on site
- Point out any areas we must not close
- Share the asbestos register for older buildings
- Clear stock, furniture or equipment away from the joints

Advice
Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
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.
Questions we are asked in Runcton
Does your area include sites such as Quarry Lane Industrial Estate, near Runcton?
Yes. Estates, retail parks and business parks around Runcton, Quarry Lane Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Is Runcton off your patch?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.
How long will the new sealant last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Can you send site paperwork?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
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.
Is any job too small?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Leave it or put it right?
Patching the worst lengths of a joint can make sense short term. But if the rest of the run is the same age and product, it’s usually not far behind, and a second visit means paying for access again. We can price a patch and a full reseal side by side. Around Runcton, it’s better to renew all the failing joints at once. Send photographs of each area and we will quote for the lot.
What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a quote when you are ready.
