How we handle expansion joint sealing in Somerley
Few joints take as much punishment as those in a car park. Wheel loads, grit and de-icing salts attack the seal and the concrete either side; water dripping through to the deck below is often the first sign. A sealant suited to traffic and the expected movement goes in, phasing bays so the car park can stay in use. The enquiries we see most involve leaks through car park deck joints onto the level below and sealant peeling off one face of the joint, across podiums and floor movement joints, cladding panel joints and precast concrete panel joints. Whoever orders the work in Somerley, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
In and around smaller places like Somerley, 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.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Aftercare for building managers
A few simple habits keep the new joints working:
- Clear dirt from joint lines during routine cleaning
- Report split or peeling joint sealant early
- Record the sealant used and the date in the O&M file
- Raise snow-clearing blades over deck joints where possible
Keep wheels, feet and water off new joints until the sealant has cured. The time varies with product, conditions and joint depth. Keeping the area coned off until then avoids tyre marks and damage.
External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint. Catching it early keeps the water outside.
Somerley: questions and answers
Does a coastal location like Somerley affect which sealant is used?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We check the specified product suits the exposure and pay close attention to preparation.
Is a hospital such as St Richard's Hospital somewhere you can work?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
What’s the difference between an expansion joint and a movement joint?
They’re closely related. Both let materials grow and shrink with temperature, moisture and load while the sealant stops grit and water getting in.
Is any job too small?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Do you hold CHAS accreditation?
Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
Signs you need expansion joint sealing in Somerley
The edges of the material can fail rather than the sealant. If the edge of the joint is friable, the bond fails with it, so we tell you if the edges need repairing first.
It’s worth sending us details if you spot any of the following:
- Damp inside where a wall movement joint has failed
- Expansion joints filled with dirt and stones
- Sealant pulling off the joint face
- Leaks through car park deck joints onto the level below
Schools like Birdham CE Primary School often have long brick elevations with movement joints that age quietly.
What to look for in a quote
- Will CSCS-carded applicators be on site?
- Do they follow the manufacturer’s priming guidance?
- How joint depth will be controlled
- The named product and why it was chosen
Traffic, movement and joints around Somerley
Somerley sits close to the coast, within about 2 miles. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, so a failed joint lets more in and the edges break up sooner. At about 59 miles from central London, Somerley is within reach of the capital. The South East has large numbers of industrial estates and warehouses along the motorway corridors; their floors carry heavy traffic every shift.
For an estate such as St Richard's Hospital, 5.2 miles north-east of Somerley, the joints in ramps, decks and long building elevations all need attention over time. For buildings at a park such as Enborne Business Park (2.8 miles south-east of Somerley), brick and panel movement joints are easy to forget until one leaks.
Somerley is about 4 miles north-west of Selsey, in West Sussex. Any commercial site in Somerley is covered, whether it’s a single job or part of a planned programme.

What else we do in Somerley
Should maintenance staff do it?
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
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.
How a job runs
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. If others near Somerley need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take.
- Every joint is cleared of the failed seal and any grit packed into it.
- Edges are checked, and we tell you if any need repairing before sealing.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Each area is handed back after its cure time, under our 12-month guarantee.
Preparing the site
- Send any specification or drawings in advance
- Make sure the joints can be reached
- Arrange parking or a loading space

Advice
How the quote is worked out
What shapes the price:
- The total length or number of joints
- Removal of failed or old sealant
- Access and working height
- Specialist products, such as fire-rated or hygienic sealants
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
What to include in your enquiry
Diagnosis starts before we arrive. Let us know:
- The site address and postcode
- Rough lengths or quantities, or drawings if you have them
- Any dates the work must fit around
- Anything awkward about access or site hours
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
Why deal with it now?
A like-for-like reseal of a joint that keeps splitting rarely lasts. A higher movement class, or a design change by the engineer, may be needed, and we’ll say so before quoting. Around Somerley, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we will quote for the lot.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
