Your questions about bath resealing in Lambton
Does someone need to be in?
Yes. The technician needs access to the room for the visit, at a time that suits you.
Will the price change on the day?
The price is fixed for what the photos show. If there’s more, we will tell you before starting.
Can you repair something that’s been repaired before?
Most of the time. Let us know what was used before.
Is it worth repairing rather than replacing?
Normally, when the rest is in good condition. A repair avoids removal and making good. We’ll tell you honestly if replacement makes more sense.
Is it safe with children and pets around?
Yes, as long as they stay out of the room we’re working in. We’ll tell you when the room can be used again.
Can new silicone go over old?
No, we never seal over old silicone. It’s removed, cleaned off and the joint dried first.
How do I stop mould in sealant?
Mostly moisture and poor ventilation. We use mould-resistant silicone, and ventilation helps it last.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are frequently glad to have it sorted.
Bath resealing in Lambton without replacing anything
Preparation is everything in a reseal: every bit of old silicone out, mould treated, the joint clean and dry. Then the fresh sealant goes on, in a neat, continuous bead. We regularly repair wet rooms, shower trays & enclosures and basins & vanity units, and the jobs we see most are damp near the bath and old sealant that looks dirty.
All our work is covered by a one-year guarantee.

Resealing in Lambton: why it matters
Putting new silicone over old doesn’t last. It peels within weeks, and traps mould underneath. We remove the old sealant completely. Set against the cost of replacement, a repair is typically a fraction of the price, because there’s no removal, plumbing or making good. The quote lists exactly what you are paying for.

Aftercare tips
Simple care helps the repair last. Our advice:
- Reseal at the first sign of lifting
- Don’t stand toiletries on the seal
- Dry the seal after bathing
- Clean the sealant gently and regularly
Keep the room well ventilated, and wipe the joints after use.
Black mould in sealant isn’t just unsightly. An early reseal keeps water where it belongs.
DIY kit or professional repair?
Kits are cheap and easy to find, but many of the jobs we do start with putting right a DIY repair. Doing it properly first is typically the cheaper route.
We understand the appeal of fixing it 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.

We carry out planned and one-off repairs for housing associations and facilities teams in Sunderland and across the UK. A repair avoids taking out and refitting, which is easier on the people living there.
