Friern Barnet questions
Are you a vetted contractor?
Yes, including CHAS, Constructionline and SafeContractor. The full list is on our accreditations page.
Do you work in Friern Barnet?
We do. Repair technicians travel to Friern Barnet from across the region, and the price is the same as everywhere else.
How long will it take?
Most reseals take about two hours. Leave it to cure before use.
Can you repair something that is been repaired before?
Yes, regularly. Removing the old work can add time, and that is in the quote.
Do you work for landlords and businesses?
Yes, often. We quote for multiple addresses and fit around tenancy changeovers.
How soon can you come?
It depends on the time of year and where you are. We’ll offer you dates when we send your quote.
How long before I can shower?
You’ll get the curing time from us, typically around a day.
Do you seal over the old sealant?
Never over old. The old sealant is cut out and the joint cleaned and dried.
Different materials, different repairs
Baths
We fill the bath before sealing, so the joint is at its widest.
Sinks and worktops
We reseal basins, vanity tops and kitchen worktops, once the joint is completely dry.
How to look after the repair
A little care keeps the finish looking good. Our advice:
- Don’t stand toiletries on the seal
- Clean the joints with a mild cleaner
- Wipe the joints dry after use
- Ventilate the bathroom well
Good ventilation is the best protection, and dry the joints after bathing to keep mould away.
Reseal before water gets in. Split or lifting sealant is a sign it’s time.
Should I try a DIY kit first?
What a professional repair adds is preparation, colour matching and finishing. We clean and key the area properly, mix the colour to your surface and finish it to the same sheen, then guarantee it for a year.
Kits are cheap and easy to find, but the repairs we redo most frequently are DIY ones that have discoloured or lifted. Doing it properly first is generally the cheaper route.
The process
The work is clean and fairly quiet, so you can carry on at home. Protection goes down first, then the work takes about two hours for a bath. At the end we talk you through the curing time and the aftercare.
- The surrounding area is protected and the joints masked.
- Old sealant and residue are removed.
- The joint is cleaned, treated and dried.
- Fresh silicone is applied in a continuous bead.
- The bead is smoothed, the tape removed and the seal left to cure.
Before we arrive
- Let us know if it has been repaired before
- Mention any parking restrictions or tricky access
- Make sure the room can be ventilated

Prices and what affects them
Every quote is fixed and free. What we look at:
- Whether old repairs or coatings need taking off
- How hard the colour is to match
- How many areas need work
- How easy the damage is to reach
Instead of hourly rates, we fix the price before we start. Damage, material and access decide it.
Getting a price from pictures
We price nearly every job from photos. This is what we need:
- A photo taken from further back
- A clear, close picture of the problem area
- A coin or ruler next to the damage for scale
- Whether it’s been repaired or coated before
For most jobs, pictures are all we need to give you a price. Tell us what happened and where you are, and we’ll send back a fixed quote and some dates.
For landlords and businesses
If you manage property in Friern Barnet, we can repair and quote for several addresses together. Just send photos for each address and we’ll price them together.
Rental properties take more wear, and replacing items every time a tenant leaves is expensive. Repairing between tenants keeps the property presentable for less.
