Questions from Ashley
Will you come out to Ashley?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Mottisfont & Dunbridge station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can new sealant go on top of the old bead?
No. Fresh silicone does not stick to the old layer, so it soon lifts and traps water. We cut the old bead out completely.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
How long should I leave it?
It depends on the product and the conditions. We tell you how long to leave it before we go.
New build mastic around Ashley
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you’ve bought a new home near Mottisfont & Dunbridge station, the sealant around baths, showers and frames is worth checking in the first year or two.

Near you in Ashley
For rail, the closest station is Mottisfont & Dunbridge station, about 5 miles south-west of the centre. Other landmarks nearby include Royal Hampshire County Hospital (5.4 miles east).
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Landlord and commercial work in Ashley
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
What we do, step by step
When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take a few hours in a single home. In a small place like Ashley, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Mention any tricky access
- Mention if the joints have been sealed before
- Mention any leaks or damp you’ve noticed

What the job involves on each surface
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out and baths are filled before sealing.
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish ready for viewings. We’ll plan around viewing times.
Do you need new build mastic in Ashley?
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
The most common problems we see are:
- Beads laid onto grit and dust from the build
- Skirting joints opening in the first winter
- Untidy sealant flagged on a snagging list
- Sealant work across a run of new homes
Around Ashley, as everywhere, new build mastic is only as good as the preparation behind it.
What your quote should include
- What insurance they hold
- What happens if the job turns out different
- When the joint can take water or movement
- How much experience the applicator has
Looking after it afterwards
After the cure time, these simple habits help:
- Act quickly if a seal starts to leak
- Keep pictures and emails about snagging items
- Open a window or run the fan after bathing
- Wait for the cure time before using a resealed shower
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents.
Early snagging is easier snagging. Small faults turn into leaks if left in a busy bathroom.
When something else is needed
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Leaks from pipes, valves or wastes, which need a plumber
- Baths and trays that move too much for sealant to cope with
- Settlement cracks that need a surveyor
If in doubt, call 0345 464 0079 or email us and we will say what we think.
