How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Open a window or run the fan after bathing
- Avoid running a DIY bead over the old one
- Get a leaking seal dealt with straight away
- Put sealant faults on your snagging list early
Don’t stand on the bath edge or the lip of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
Early snagging is easier snagging. Small faults turn into leaks if left over time.
New build mastic in Lyford, done properly
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover with a sealant suited to each area. Common call-outs are for shower seals failing in the first year or two and kitchen sealant that has pulled off the wall, across windows & doors, kitchens and bathrooms & en suites.
Work in a small place like Lyford just needs the journey and access planning, and the work itself is the same as on any site.

Plot handovers
Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing to keep callbacks down.
Kitchens
Sink joints are wet all the time. We use a sealant suited to kitchens.
How the visit works
We keep the work tidy and contained to the area we’re working on. The job usually takes anything from a few hours to several days, depending on the number of plots, and we explain the cure time before we leave. For a village or hamlet like Lyford, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you’re given the cure time.
Before we arrive
- Tell us about any water getting in
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules

Common questions in Lyford
Will you come out to Lyford?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover Lyford for new build mastic?
Yes, Lyford is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
Can you do plot mastic on a new development?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. We clean and prime joints properly to keep callbacks down.
My new home is still under warranty. Should I contact you?
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.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint.
Do you work for landlords and businesses?
Yes. Domestic, commercial and hotel work are all part of what we do.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Will you just run a new bead over the existing one?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.
