Bathroom Resealing in Northaw Valley
Problem with your baths, showers and worktops in Northaw Valley? We cut out the old, prepare the joints and apply the right sealant.
- Shrunken sealant along the back of a worktop
- Smears of silicone across the tiles
- New sealant laid over old sealant that is now lifting
How we handle bathroom resealing in Northaw Valley
Showers work their sealant harder than baths. Trays, enclosures, screen profiles and wet room floors all need a flexible, waterproof seal. They’re resealed with anti-fungal sanitary silicone, tooled smooth so water runs off instead of sitting in a ridge. Common call-outs are for black mould in the silicone that won’t clean off and splits where the tray meets the wall, across shower trays & enclosures, kitchen worktops & upstands and wet rooms.
In a village or hamlet like Northaw Valley, homes are often older cottages and farmhouses alongside a few newer houses. Movement in older walls and floors tends to show first as cracked grout or split sealant.
You are covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

What we’re called out for in Northaw Valley
Silicone needs a clean, dry surface without any grease to stick to. Soap residue, oils and leftover silicone film all get in the way, and a joint that looked fine soon begins to come away.
The most common problems we see are:
- A joint torn by a bath that flexes
- Black spots spreading through the bead
- Cracked, shrunken or lifting silicone
- Leaking joints on a shower screen
If you live in an older home near Parish Church of St Thomas A Becket, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
Questions to ask before booking
- Who does the work, and how experienced they are
- Whether you can choose the colour
- What preparation is included
- Whether they’re fully insured
Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.

Bathrooms and kitchens in Northaw Valley
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
For landlords with property near Crews Hill station, fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay. Schools such as St. John's Senior School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

What does bathroom resealing cost?

Can new silicone go straight over the old?

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.
How long does it take to reseal a bath or shower?
It depends on how many joints there are and how much old sealant has to come out. Allow a couple of hours for a typical bath or shower.

Yes. Every job carries our one-year guarantee, and we’re fully insured.
What affects the cost of bathroom resealing
Some jobs are bigger than they look, and some smaller. The main factors:
- The amount of work
- Whether old sealant or filler has to be cut out
- The product the joint needs
- Any mould that needs treating
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What we need to know
There’s no need for technical detail. Just tell us:
- Whether it has been sealed before
- What’s wrong with the joints now
- Roughly how big the job is
- Any access issues, like height or stairs
If you’re in Northaw Valley and need bathroom resealing, phone 0345 464 0079 or email us. A short description of the job and where it is helps us quote, and you will get a clear quote before work begins.
Why it’s worth doing now in Northaw Valley
Most of the work in a good reseal happens before any silicone goes on: removing all the old sealant, degreasing the joint, treating mould and drying it properly. Skip those steps and even the best silicone fails early. Older cottages and farmhouses around Northaw Valley can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.
