Aftercare tips

Good habits make a big difference to how long a repair lasts:

Keep the joints dry
Keep bottles off the joints
Give the seal a regular clean
Air the room after use

Use the extractor fan, wipe the joints dry after use, and give them a regular clean with a mild cleaner to slow mould growth.

Black mould in sealant isn’t just unsightly. Resealing early keeps water out of the walls and floor.

Bath resealing in Denbigh without replacing anything

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. We work on shower trays & enclosures, basins & vanity units and baths, and common reasons people get in touch are water getting behind the bath or tray and an untidy old seal.

A one-year guarantee comes as standard, so you’re not left on your own once we’ve gone.

Denbigh questions

Can you quote from pictures?

Nearly always. If pictures don’t show enough, we will ask for another angle.

What happens next?

We come back with a fixed quote. There’s no obligation to book.

It’s been repaired before. Can you still fix it?

Typically, yes. We remove the old repair before doing a new one, so mention it when you send photos.

Is it OK to have pets in the house?

Just keep them out of the work area. We’ll let you know when it’s safe to use again.

Is there a call-out fee?

No. Our quotes include travel, with the same prices everywhere we work.

How long before I can shower?

You’ll get the curing time from us, typically around a day.

How quickly can you book me in?

It depends on the time of year and where you are. We will offer you dates when we send your quote.

Will the price change on the day?

Your quote covers the damage in the photos. Anything extra is discussed before we begin.

Should I try a DIY kit first?

We understand the appeal of fixing it yourself. The risk is that a kit repair hides the damage for a while, then fails, and then the old filler has to be removed first.

DIY kits are sold for most surfaces, and they can make a small mark look better. Where they fall down is colour and preparation: they come in a handful of shades, and if the surface is not prepared the repair will not last.

Different materials, different repairs

Shower trays

Trays are sealed with weight on them, so the joint is at its widest.

Sinks and worktops

We reseal basins, vanity tops and kitchen worktops, once the joint is completely dry.

Work for landlords and builders

Hotels, guest houses and holiday lets cannot afford rooms out of action for long, so we keep visits short and tidy. We will fit around changeovers where we can.

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

What we do, step by step

Visits start with a quick look at the job together, so there are no surprises. Next, we cover and mask everything nearby and the work begins. It normally takes around two hours, and we will tell you if anything changes.

The surrounding area is protected and the joints masked.
We remove the old sealant and every trace of residue.
The joint is cleaned, treated and dried.
We run a continuous bead of new silicone.
We smooth the bead, remove the tape and leave it to cure.

Resealing in Denbigh: why it matters

Compared with repairing water damage, resealing is cheap. It’s quick, tidy and protects your home. Every job is a little different, so we price each one individually. What’s damaged, how badly and how easy it is to reach all play a part, and doing several things on one visit costs less than separate visits.
