New-build mastic & snagging in Down Street, East Sussex
Professional new build mastic in and around Down Street, with old sealant always removed completely.
- Gaps between new skirting and floors
- Sealant work across a run of new homes
- Smeared, uneven beads picked up at snagging
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
How we handle new build mastic in Down Street
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly instead of bonding to the dust. We’re often asked to deal with cracked caulk along new skirting and gaps behind new kitchen upstands, across windows & doors, show homes and plot handovers.
In a village or hamlet like Down Street, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

How the job changes by surface
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. We reseal it with a weatherproof, flexible sealant.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Follow the cure time we give you
- Do not seal over failed sealant yourself
- Photograph failed sealant before it’s redone
- Look at the sealant regularly in the first couple of years
Avoid standing on the rim of the bath or the edge of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you.
What we do, step by step
We keep the work tidy and contained to the area we’re working on. Expect the work to take a few hours for most snagging lists, longer for a run of plots. For a village or hamlet like Down Street, 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.
- Each joint is checked for movement before any work starts.
- 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.
Preparing for the visit
- Mention any parking rules near the property
- Keep children and pets away from the work area
- Clear the area around the work

Why act early in Down Street
Resealing everything on a snagging list in one visit is normally simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times. Older cottages and farmhouses around Down Street can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on how much there is to do, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
