Common problems we fix in Netley
Most movement joint failures come down to the joint stretching further than the sealant can take. Cohesive failure, a split through the centre, usually means the joint or product wasn’t right for the movement. Resealing like for like often fails the same way unless width and product are reviewed.
Site and facilities staff are often the first to spot these:
- Water getting into the wall through a failed joint
- Debris jammed in movement joints
- Spalled or broken joint edges in floors and decks
- Water dripping through deck or ramp joints
Schools such as Netley Abbey Infant School have movement joints in their walls and floors that are easy to overlook.

Expansion joint sealing in Netley
We’ve been sealing expansion and movement joints for over 20 years. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. If you are dealing with spalled or broken joint edges in floors and decks and movement joints with split or torn sealant, we can put it right. A single leaking joint is often how a building in Netley first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
In a smaller place such as Netley, floor and movement joints are often in agricultural and rural business units, schools and the odd small industrial yard. Their slabs and walls still need movement joints that work.
Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

How the job changes by surface
Joints between different materials
Junctions between brick and render, or concrete and cladding, move independently. We choose a sealant that grips both faces.
Internal floor movement joints
Floor joints include saw-cut joints and construction joints. A semi-rigid filler is common in trafficked industrial floors, with a flexible sealant where movement is larger.
Why deal with it now?
Patching the worst lengths of a joint can make sense short term. The remaining sealant is often close to failing too, and a second visit means paying for access again. Where it helps, we quote both options. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.

Slabs, ramps and loading bays in Netley
With the shore within about 1 mile, Netley counts as a coastal location. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, which is why split joints are worth sealing before the edges deteriorate. Netley has at least three named business or industrial parks inside a 3-mile radius. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.
Business parks such as Ensign Way Business Park, 1.6 miles south-east of Netley, have car parks, paved areas and long brick and panel elevations, all with movement joints. Another example is Basepoint Business Centre (2.5 miles north-west of Netley), where floors and yards would be done in stages around the occupiers.
Netley is about 3 miles north-east of Hythe, in Hampshire. Anywhere in SO31, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Across Hampshire, 723 places are covered, including Netley.

Around Netley
Locally, jobs take us to sites close to Grove Park Business and Enterprise College, Westwood Woodland Park and The Hamble School, among other places. There’s a railway station in Netley itself: Netley station. Nearby you will also find Bursledon Brickworks Industrial Museum (2.5 miles east) and Coldeast (2.8 miles east). For a walk, there’s Mercury Marshes.
After the work
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Report split or peeling joint sealant early
- Look over external and deck joints after a hard winter
- Avoid parking heavy plant or pallets on joint lines
- Leave barriers in place until fresh joint sealant has cured
Our workmanship on movement joints carries a 12-month guarantee. Record which product went into which joints in the building file.
An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall. A sound seal keeps the joint working.
Questions about Netley
Can you take on a job at a hospital such as Hythe 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.
Is Netley too small for you to travel to?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
What guarantee do you give on joint sealing?
It’s backed by our 12-month guarantee. If a joint we sealed fails inside the 12 months, let us know.
Do you offer coloured sealant?
That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
What about RAMS and site documents?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
What sealant do you use in movement joints?
The specification comes first, then the joint’s movement and exposure. The quote states the sealant and its movement class, so you know what’s going in.
What if there’s asbestos in the old mastic?
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.
Our process
Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Work in places the size of Netley is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
- Every joint is cleared of the failed seal and any grit packed into it.
- Any broken arrises or friable edges are flagged before work goes further.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Getting the site ready
- Send any specification or drawings in advance
- Agree which areas must stay open
- Arrange parking or a loading space
