Bathroom Resealing in Northbrook
Professional bathroom resealing in and around Northbrook, with old sealant always removed completely and a 12-month guarantee.
- A reseal done over the top of the old bead
- Water getting behind the bath panel
- Black spots spreading through the bead
Why act early in Northbrook
Fresh sealant smartens a bathroom or kitchen with very little disruption, which helps when a home is being let or put on the market. A smeared, uneven DIY bead does the opposite. Older cottages and farmhouses around Northbrook can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first.

About our bathroom resealing in Northbrook
The secret of a lasting bead is the preparation. Every bit of old silicone comes out, down to the thin film left on the tiles, after which the joint is degreased and any mould treated. Only once it’s dry does the new bead go on. Common call-outs are for water getting behind the kitchen upstand and leaks into the floor or ceiling below, across baths, kitchen worktops & upstands and sinks & splashbacks.
Somewhere as small as Northbrook, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

The process
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take around two hours for one bath or shower, longer for a whole bathroom. In a small place like Northbrook, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First the area is protected and every bit of old sealant removed.
- Next, the joint is cleaned and any mould is treated.
- Once it’s dry, any bath is filled so the bead is laid with it at its heaviest.
- New anti-fungal silicone goes on in a colour to suit and is tooled to a clean finish.
- We clear away and tell you when it can get wet, generally after around 24 hours.
Preparing for the visit
- Keep children and pets away from the work area
- For indoor joints, keep the area dry beforehand if you can
- Let us know about earlier repairs to the joints

Advice
Signs you need bathroom resealing in Northbrook
No sealant lasts indefinitely. Daily water, heat and cleaning products take their toll over the years, so its life depends on how the room is used, cleaned and aired.
It’s worth asking for a quote if you see:
- Leaking joints on a shower screen
- Gaps where the bath or tray has moved
- Cracked, shrunken or lifting silicone
- Lumpy, uneven sealant from a DIY attempt
Rented homes near Micheldever station change hands often, and mouldy sealant is one of the first things a new tenant notices, so it’s worth renewing between lets.
What your quote should include
- How long to leave it before use
- How the surfaces are prepared before sealing
- Whether they’re fully insured
- What product goes in the joint
Quotes for bathroom resealing in Northbrook
Some jobs are bigger than they look, and some smaller. The main factors:
- How easy the joints are to reach
- Working hours on commercial sites
- The number of rooms or windows
- Whether old sealant or filler has to be cut out
Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear price for the lot.
Asking for a quote
To help us quote quickly, please include:
- If someone has resealed it before

It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. Whenever you’re ready, call 0345 464 0079 or send us an email.

FAQs for Northbrook
Is Northbrook within the area you cover?
Yes. Northbrook is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Are you insured?
Yes. We’re fully insured.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Northbrook.
Is it OK to put new sealant on top of the old bead?
No. New silicone won’t bond to old silicone, so it lifts and traps water and mould underneath. We always take the old sealant out completely.
Do you do kitchens as well as bathrooms?
Yes. Next to the sink we use a food-safe product where it’s needed.
When can I use the bath or shower again?
After around 24 hours in most cases. We will tell you the cure time for the product we used.
Can mouldy silicone be sorted out?
Yes, by replacing the sealant. Cleaning products may lighten it, but the lasting fix is new anti-fungal silicone on a clean, treated joint. Airing the room well helps stop it returning.
Landlord and commercial work in Northbrook
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
How the job changes by surface
Shower trays & enclosures
There are usually two jobs in a shower: the tray-to-wall joint and the enclosure joints. Both take water every day, so each is cut out and renewed with anti-fungal sanitary silicone.
Wet rooms
Wet room floors move slightly as they’re used, so the internal corners need silicone rather than grout. Where grout in a corner has cracked, we can replace it with sealant.
Bathroom resealing around Northbrook
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
For site and facilities teams at buildings such as Micheldever CofE Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes. For an older house near a landmark such as Church of St Mary, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
