About our expansion joint sealing in Rickmansworth
For movement joints in Rickmansworth, photographs and approximate lengths are the best start. We’ll come and look where photographs don’t show enough. You can also give us a call on 01277 525 020 or email a schedule or drawings to talk the joints through. If you have leaks through car park deck joints onto the level below and water getting into the wall through a failed joint, we can put it right. A single leaking joint is often how a building in Rickmansworth 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.
Movement joints on schools, offices and shops in towns like Rickmansworth are easy to overlook until water gets in. A split or hardened joint lets rain into the wall, and it can no longer take up the movement.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Traffic, movement and joints around Rickmansworth
The 3 miles around Rickmansworth 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. Rickmansworth is in the South East, one of the UK’s drier regions. Outside joints in yards and car parks still have to be dry before sealing, and where de-icing salt is spread in winter, open joints let it in.
Hospital campuses such as Harefield Hospital (2.4 miles south of Rickmansworth) grow in stages, leaving movement joints wherever new blocks meet old. Schools such as Saint Joan of Arc Catholic School have movement joints in their walls and floors that are easy to overlook.

On site: what to expect
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Town-centre premises in Rickmansworth may have limited parking, so tell us what’s nearby. Industrial and business units typically have yard or car park space.
- First the joints are inspected, widths measured and the type of failure noted.
- You receive a fixed quote stating the product and the movement it is rated for.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Getting the site ready
- Warn occupants and staff about the work
- Share the asbestos register for older buildings
- Let us know about inductions and permits

Cost factors for movement joints
These are the things that shape the price:
- Site requirements such as inductions and permits
- Removal of failed or old sealant
- Backing rod, priming and other preparation
- Specialist products, such as fire-rated or hygienic sealants
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Sending details for a quote
It doesn’t need to be a full survey. A few details are enough to get going:
- Access details, including height
- Specification clauses that apply
- Your programme or deadline
- What the building is and how it’s used
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to ring 01277 525 020 or email a schedule or drawings with what you know.
What we are called out for in Rickmansworth
When the movement exceeds the sealant’s capability, the bead tears. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. Resealing like for like often fails the same way unless width and product are reviewed.
What tends to prompt an enquiry:
- Spalled or broken joint edges in floors and decks
- Damp inside where a wall movement joint has failed
- Sealant pulling off the joint face
- Brittle, chalky sealant on external joints
Warehouse floors on estates like Peerglow Industrial Estate, 1 mile to the east of Rickmansworth, carry pallet trucks and forklifts over every saw-cut joint.

What happens if it’s left?
Combining joint work with other maintenance reduces set-up costs. Leaking joints need sealing now, as damage continues meanwhile. We can split the scope into urgent and planned. In Rickmansworth, as anywhere, the simplest time to fix a failed joint is before it leaks. Once water gets in, there’s drying out and making good as well.

Aftercare for building managers
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Keep scrapers and ploughs from dragging across joint sealant
- Keep traffic off new joints until the cure time is up
- Avoid parking heavy plant or pallets on joint lines
- Put movement joints on the planned maintenance inspection round
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. The first sign is often a damp patch indoors by which time the joint has been open for a while. Catching it early keeps the water outside.
FAQs: Rickmansworth
Can you work on a hospital site such as Harefield Hospital?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Will our site in Rickmansworth have to close for joint sealing?
Usually not: we work in sections and hand each one back once it has cured. Tell us which hours and entrances we can use and we’ll plan from there.
What if the joint edges are damaged?
Spalled edges need repairing before a new seal will last, and we’ll point out where that’s the case. Sealing over them leads to early failure.
Which sealant will you use?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Are you CHAS accredited?
Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
When can you be on site?
Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
Do you reseal car park expansion joints?
Yes. These joints take wheels, salt and water, so product choice matters, and we’ll tell you if any edges need repairing first.
