How we handle bath resealing in Northwood
The key to a good reseal is getting all of the old silicone out. New silicone won’t bond to old, which is why many DIY jobs peel. Whether it’s silicone coming away from the tiles and water getting behind the bath or tray, we can help.
You’re covered for a year from the day of the repair. If anything is not right, ring us and we will come back.

Northwood: your questions answered

We protect the room with dust sheets and masking first, and we clean up when we have finished.

Every job gets a fixed price from your pictures. Send a close-up of the damage and a wider photo with your HA6 postcode.

Do you hold any accreditations?

How we price bath resealing
We charge the same across the UK, including Northwood. What changes the price is:
- The size and number of damaged areas
- The material and finish
- Where the damage is and how we get to it
- How hard the colour is to match
A repair usually costs much less than people expect, especially compared with replacing and refitting. Send photos and we’ll give you the exact figure.
How to get a fixed quote
Good photos mean an accurate price. Here’s what helps:
- What it’s made of, if you know
- Daylight if possible, and no flash reflection
- Any earlier repairs or coatings
- Something in shot to show the size
Send us a photo of the damage and a wider shot of the entire item, with your HA6 postcode, and we will come back with a fixed quote.
What your bath or shower is made of matters
Baths
We fill the bath before sealing, so the joint is at its widest.
Shower trays
Trays are sealed with weight on them, so the joint is at its widest.

Resealing in Northwood: why it matters
Compared with repairing water damage, resealing is cheap. It’s quick, tidy and protects your home. Instead of hourly rates, we price the entire job up front. Damage, material and access decide it, and doing several items at once reduces it.
What you get with us
- Most jobs done in one visit
- We’ll tell you if it’s not worth repairing
- Accredited with CHAS, Constructionline and SafeContractor
- Same prices wherever you are
Take a look at our prices page.
Keeping it looking good
To keep it looking its best for years:
- Store bottles on a shelf
- Clean the joints with a mild cleaner
- Reseal when black spots won’t clean off
- Open a window after bathing
Use the extractor fan, dry the joints after bathing, and clean them regularly with a mild cleaner to slow mould growth.
Don’t wait until water gets behind the bath. Split or lifting sealant is a sign it’s time.
Common problems we fix in Northwood
Sealant doesn’t last forever. Every bath or shower adds moisture and soap residue, which mould feeds on, and the joint flexes each time the bath fills.
Send us a photo if you notice any of these:
- Gaps in the seal
- Water getting behind the bath or tray
- Black mould in the sealant
- Missing sealant behind the taps

The process
Your technician turns up at the time we agreed with you, introduces themselves and looks over the damage before anything else. The floor and nearby surfaces are covered before any work starts. Most visits take around two hours, and the room is left clean and tidy.
- The old silicone is cut out completely.
- We remove the residue and clean the joint.
- Any mould is treated and the joint dried.
- The bath is filled with water, or weight put on the tray.
- We apply fresh mould-resistant silicone and tool a neat bead.
Getting ready for the visit
- Let us know which floor the room is on
- Let us know about parking or access
- Mention any earlier repairs or resurfacing
How to get a price
The quickest way to a price is to send a couple of pictures using our quote form or ring us. We will tell you honestly whether it can be repaired.
