Remedial sealant in Maple Cross
A movement joint stops working when its sealant splits or sets hard. The old sealant comes out and backing goes in to control the depth, before resealing with a flexible product suited to the movement. We are often asked to deal with products that weren’t meant for the joint and a shower that leaks however often it’s resealed, across botched or over-sealed joints, mouldy bath & shower sealant and leaking tray & enclosure joints.
For a small place like Maple Cross, remedial sealant is planned like any other job: it just means planning the journey and access beforehand. Once we’re there, the bathroom or kitchen gets the same care as anywhere else.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What affects the cost of remedial sealant
You’ll get a clear quote before we start. It’s based on:
- Any working-time requirements on site
- Whether there’s mould to deal with
- The amount of work
- How many areas need sealing
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or send us an email for an honest opinion and a quote.
What we need to know
Photos help, but a description is a good start. Please mention:
- The type of property
- How we’d reach the joints
- What’s wrong with the joints now
- Photos by email, if that’s easy
Getting a quote is simple: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job.
How it works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours, depending on how many layers have to come out, and the area is left clean. Somewhere as small as Maple Cross, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about stairs, lifts or work at height

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Look for stains below bathrooms now and then
- Don’t wait for a small gap to become a leak
- Clean sealant with mild products only
- Keep the room well ventilated
Watch the joint over the first few weeks, especially if movement was the problem. Should anything change, phone 0345 464 0079 or drop us an email.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into floors, walls or ceilings. Sorting it early limits the damage.
What we’re called out for in Maple Cross
Water from somewhere else can ruin a good seal. A slow leak behind the tiles soaks the joint from the back, and the sealant lifts or goes mouldy from underneath.
Signs it’s time to call us include:
- Beads that never stuck properly
- Dark patches showing through the sealant
- Thick, messy sealant smeared over tiles
- A second bead peeling off the first
Letting a property close to Rickmansworth station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Maple Cross homes and their sealant
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
Schools such as Maple Cross Junior Mixed Infant and Nursery School are buildings too, and washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes. In the older streets around Church of St Thomas of Canterbury, walls and floors in older homes can move, and sealant and grout show it first.
Maple Cross is about 2 miles south-west of Rickmansworth, in Hertfordshire. Wherever you are in the WD3 postcode area, we can carry out remedial sealant at your property. Maple Cross is one of 381 towns and villages in Hertfordshire we cover. We also work in London, around 20 miles away.
All of WD3 is within our area for remedial sealant, from the main roads to the quietest streets. Whether your property is on Pinchfield, Tichborne and Woodwicks or a nearby road, our applicators can take on the job.

Landmarks near Maple Cross
Around Maple Cross, our work takes us to homes and buildings near The Dumb Bell pub and Rickmansworth Aquadrome.

Why it’s worth doing now in Maple Cross
Leaks that are left keep doing damage out of sight: soaked floorboards, ceiling stains below and blown plaster. Dealing with the joint now is a small job by comparison. Older cottages and farmhouses around Maple Cross can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.

How the job changes by surface
Movement & expansion joints
Movement joints in floors, walls and façades need a flexible sealant set to the right depth. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed.
Over-sealed & botched joints
Thick, smeared sealant looks messy and hides problems. Taking it back shows what’s underneath.
