Should I try a DIY kit first?

DIY kits are sold for most surfaces, and they can make a small mark look better. The trouble is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler frequently lifts.

If you’ve already tried a DIY fix, that’s fine. We remove the old filler and start again, so it will not stop us repairing it. Just mention it when you send photos, as it can add time.

Bath resealing in Birchgrove, done in place

A fresh seal protects your bathroom. Old, split or mouldy sealant lets water get behind the bath or tray, and resealing puts a stop to that. Whether it’s black mould in the sealant and sealant that’s split or lifting, we can help, on wet rooms, shower trays & enclosures and baths alike.

Every job is backed for twelve months, and the guarantee is the same wherever you live. If something goes wrong with the work, we come back.

Is resealing worth it?

Sealing over old silicone is a false economy. It soon peels, and mould stays trapped behind it. A proper reseal removes the old first. Every job is a little different, so each one is priced on its own. What’s damaged, how badly and how easy it is to reach all play a part, and combining jobs on one visit brings the cost down.

For landlords and businesses

We also carry out snagging repairs for builders and developers, putting right damage done during fitting. We’re CHAS, Constructionline and SafeContractor accredited.

Rental properties take more wear, and replacing items every time a tenant leaves is expensive. Repairing between tenants keeps the property presentable for less.

Your questions about bath resealing in Birchgrove

Can you repair something that is been repaired before?

Yes, regularly. Removing the old work can add time, and that’s in the quote.

Does someone need to be in?

We need someone to let us in. You don’t need to watch us work.

Do the materials smell?

It depends on the job, but frequently a little. Open windows and an extractor fan help.

What does bath resealing cost?

We give a fixed quote based on pictures of the damage. Send a close-up and a photo of the entire item with your CF14 postcode.

How long before I can shower?

You will get the curing time from us, normally around a day.

Is repairing better than replacing?

Generally, yes. Replacement brings removal, refitting and making good, which a repair avoids. We’ll be honest if it’s not worth it.

My seal keeps tearing. Why?

The bath or tray is probably flexing. Persistent splitting can mean the support needs attention.

I rent my home. Can I book you?

Of course. Ask your landlord first, and we can send them the quote if that helps.

What happens on the day

Your technician turns up when we said we would, introduces themselves and checks the damage against your pictures first. Dust sheets and masking tape go down before any work starts. The work itself takes about two hours for a bath, and we leave the room as we found it.

First we strip out every bit of the old mastic.
The joint is cleaned and any mould treated.
The joint is dried thoroughly.
For a bath, we fill it with water first so the joint is at its widest.
We apply new mould-resistant silicone and tool it to a neat finish, including around the taps.

Preparing for the visit

Let us know if it has been repaired before
Clear the area around the damage
Mention if the room is upstairs or in a flat
