For landlords and businesses
Letting agents often send us photos straight from the inventory. That means we can quote before you even visit the property, and we can arrange access with the tenant directly if that helps.
We are used to working with agents and managing companies. Just send pictures, the address and how to get access and we will handle the rest.

How the visit works
It’s a tidy, low-fuss visit. We confirm the time with you beforehand, cover and mask the work area, then carry out the work, which generally takes around two hours. If we find something your pictures didn’t show, we’ll explain it before carrying on.
- The old silicone is cut out completely.
- Residue is removed and the joint cleaned.
- We treat mould and dry the joint thoroughly.
- The bath is filled with water, or weight put on the tray.
- New mould-resistant silicone is applied and tooled neatly.
Preparing for the visit
- Let the surface dry out before the visit
- Let us know which floor the room is on
- Keep pets and children out of the room while we work
Ask for a price
Getting a price is easy: take a close-up of the damage and a photo from further back, send them to us with your postcode, and we will reply with a fixed price. There is no charge for the quote and no obligation.
Related advice
Keeping it looking good
A little care keeps the finish looking good. Our advice:
- Store bottles on a shelf
- Let steam out after showers
- Run the extractor fan during and after showers
- Clean the joints with a mild cleaner
Use the extractor fan, dry the joints after bathing, and clean them regularly with a mild cleaner to slow mould growth.
Damp below or loose tiles need checking quickly. There may be more going on, and we will say if you need a builder or plumber.
What bath resealing costs
Quotes are free and the price is fixed. What we look at:
- How hard the colour is to match
- How easy the damage is to reach
- How many items we do on one visit
- Any earlier repairs that need removing first
Instead of hourly rates, we price the whole job up front. It depends on the damage, the material and access, and combining items on one visit brings it down.
Quotes from your photos
Phone pictures are fine, there is no need for anything special. Make sure they show:
- A photo taken from further back
- The material, if you know it
- Your postcode, so we can check dates
- Natural light rather than flash
For a price in Portesham, the easiest route is pictures: a close-up, a wider shot and your postcode. You’ll get a fixed quote with dates to choose from.
DIY kit or professional repair?
It’s natural to want to try a repair yourself. The risk is that a kit repair hides the damage for a while, then fails, and the old filler has to come out before a proper repair.
It’s tempting to reach for a kit, but many of the jobs we do start with putting right a DIY repair. Getting it right first time is normally cheaper.
FAQs for Portesham
I’m a tenant. Can you help?
Yes. Check with your landlord; we can send the quote to them too.
Is the work guaranteed?
Yes, for a year. If anything goes wrong with the repair within the year, we return to fix it.
Will it make a mess?
Dust sheets and masking go down before we start, and we clean up when we’ve finished.
Is there any odour?
Expect a mild smell while we are working.
Do you seal over the old sealant?
Never over old. The old sealant is cut out and the joint cleaned and dried.
Do you come to Portesham?
Yes. We cover the entire UK and travel to Portesham. Send pictures and we will quote, or call 0345 017 0787.
Can you repair something that is been repaired before?
Generally, yes. Let us know what was used before and we will plan for it.
Why does mould come back so fast?
Mostly moisture and poor ventilation. Mould-resistant silicone and good ventilation help.
Resealing in Portesham: why it matters
Resealing is a small job. Leaving split or mouldy sealant lets water get behind the bath or tray, which costs far more to put right. There are no surprise extras on the day. The price we quote from your photos is the price you pay, unless the damage turns out to be different, in which case we talk to you first.
