What happens if it’s left?
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot. Around Littleworth Corner, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.

What else we do in Littleworth Corner
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Record problems with dated pictures
- Follow the cure time we give you
- Put sealant faults on your snagging list early
- Don’t seal over failed sealant yourself
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it as they wear the bead.
Early snagging is easier snagging. Left alone, a small crack can become a leak.
When it is not the sealant
We’d rather tell you now than do work that won’t last, so these are the limits:
- Leaking fittings rather than failed sealant
- Baths and trays that move too much for sealant to cope with
- Cracked trays, tiles or worktops
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.
What we seal
- Show homes
- Skirting & floors

On the day, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. Most jobs take a few hours in a single home. In a small place like Littleworth Corner, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked for movement before work begins.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
