Remedial sealant in New Town
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint fails however neatly it’s applied. Out it comes, and in goes a sealant suited to the job.

For a small place like New Town, remedial sealant is planned like any other job: it just means planning the journey and access beforehand. Once we’re there, the bathroom or kitchen gets the same care as anywhere else.

- The number of rooms or windows

What we are called out for in New Town
All sealant wears out eventually. Over the years it shrinks, hardens and gets colonised by mould, faster where ventilation is poor. At that point it has to come out.
The problems people usually mention when they call are:
- Wide, uneven beads that look worse than the old ones
- Sealant applied over old sealant that has lifted
- Sealant that came away because the surface wasn’t prepared
- Mould trapped under a layer of silicone
Rented homes near Pangbourne station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

What else we do in New Town
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Report a tray that rocks or a worktop that lifts
- Check ceilings under showers for marks
- Never fill a movement joint with mortar or grout
- Find out why the sealant failed first
Leave the new joint to cure fully before it gets wet or moves: follow the cure time we give you.
A split movement joint lets rain into walls and floors, and the longer it’s left, the more the joint edges break down. Resealing while the edges are sound is simpler.
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
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 fails, we can still redo it.
How it works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours for most joints, depending on how much old sealant has to come out, depending on the size of the job. For a village or hamlet like New Town, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First we find out how and where the joint has failed.
- We strip the joint completely, removing any layers below.
- We clean the joint, treat any mould and let it dry.
- Moving joints get backing and a flexible sealant to suit.
- We tool the joint and tell you about anything else that needs attention.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in
- Let us know about parking restrictions
