What happens on the day
Every visit runs the same way: we check the joints, protect the area around them, do the work and clear up. Most jobs take anything from a few hours to several days, depending on the number of plots. Somewhere as small as Caversfield, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.

New homes and floors in Caversfield
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Why it’s worth doing now in Caversfield
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. In a small place like Caversfield, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and agree the price before starting.

What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Broken tiles or a split tray
- Deciding who is responsible under a builder’s warranty
- Leaks from pipes, valves or wastes, which need a plumber

Caversfield: your questions answered
Will you come out to Caversfield?
Yes, Caversfield is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you cover Caversfield for new build mastic?
Yes, Caversfield is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and let us know what needs doing.
What colour sealant will you use?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before work begins.
Who should fix failed sealant in a new build?
While the snagging or warranty period runs, the builder should be your first contact. If they’re slow or the fix does not last, we can help.
Do you take on second-fix sealing for builders?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send the schedule and any specification and we’ll give you a quote.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Is the work guaranteed?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we will sort it.
Will the old sealant be removed?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Aftercare tips
Good habits help new joints last longer. A few tips:
- Follow the cure time we give you
- Check bath and shower seals every few months as the house settles
- Clean sealant with mild detergent, not abrasives
- Open a window or run the fan after bathing
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents, which can damage the surface.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you, so raise it early.
Do you need new build mastic in Caversfield?
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
These are the problems we are asked about most:
- New-build shower sealant that has already split
- Cracked sealant around new window and door frames
- Worktop and upstand sealant coming away
- Gaps opening as the house dries out and settles
If you’ve bought a new home near Bicester North station, the sealant around baths, showers and frames is worth checking in the first year or two.
