New build mastic in Marlow
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. If you’re still within the builder’s snagging or warranty period, tell them first. If you have plot mastic for developers ahead of handover and worktop and upstand sealant coming away, we can put it right, on plot handovers, bathrooms & en suites and show homes alike.
Homes around Marlow move a little with the seasons, and skirting and floor joints show it first. A flexible sealant, rather than rigid filler, keeps those joints closed.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or drop us an email.

What new build mastic looks like in Marlow
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

What happens if it’s left?
The builder is generally the first port of call while the snagging or warranty period runs. If it keeps failing or is not dealt with, we can reseal it properly. In a family home in Marlow, a failed seal around a bath or a frame lets water into places you can’t see, like the floor under a bath, the back of a panel or the inside of a wall. Left alone, that means rot, damp and a bigger repair.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.

Common problems we fix in Marlow
A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open.
Signs it’s time to call us include:
- Sealant that never bonded to the surface
- Kitchen sealant that has pulled off the wall
- Messy sealant that spoils new finishes
- Cracked sealant around new window and door frames
For new homes near Marlow station, it’s worth checking the sealant early, while snags are still fresh.

Work for landlords, hotels and businesses
We also work for property managers and facilities teams in Marlow and across Buckinghamshire. We can quote a run of properties together.
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Looking after it afterwards
So the new joints stay in good condition:
- Don’t wait for the house to settle if water is getting through
- Raise failed sealant with the developer while you’re covered
- Photograph failed sealant before it’s redone
- Follow the cure time we give you
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it as they wear the bead.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you, so raise it early.

What happens on the day
On the day, we start by going over the job with you. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. In Marlow, parking is rarely complicated, though it helps to know about driveways or restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
How to prepare
- Mention any parking rules near the property
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work
