DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Wipe joints with warm soapy water
- Act quickly if a seal starts to leak
- Follow the cure time we give you
- Raise failed sealant with the developer while you’re covered
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Report failed sealant to the builder while you are in the snagging period. Once it ends, the repair may be down to you so report it promptly.
Why deal with it now?
Resealing everything on a snagging list in one visit is generally simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times to plan around. In a small place like Cuddington, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not guesswork. That is why we ask about the job first.

Surface by surface
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out with baths filled first.
Kitchens
New-kitchen sealant is often applied in a rush. We remove it and reseal with a kitchen-suitable sealant.
When to call us in Cuddington
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
Keep an eye out for any of the following:
- New-build shower sealant that has already split
- Cracked sealant around new window and door frames
- Cracked caulk along new skirting
- Cracks appearing as a new home settles
For new homes near Haddenham & Thame Parkway station, it’s worth checking the sealant early, while snags are still fresh.

Cuddington: your questions answered
Can you help a landlord with a rental near Haddenham & Thame Parkway station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Will you come out to Cuddington?
Yes, Cuddington is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can new sealant go on top of the old bead?
No. New silicone will not bond to old silicone, so it soon lifts and traps water. We cut the old bead out completely.
How long does the job take?
That depends on the amount of work, but most jobs take anything from a few hours to several days, depending on the number of plots. We’ll tell you when we quote.
Do you guarantee your work?
Yes. Every job comes with our one-year guarantee.
Are you fully insured?
Yes, we are fully insured.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What we do, step by step
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours in a single home.
