About our new build mastic in St Mary Bourne
Across St Mary Bourne, we work for both new-home owners and the builders handing those homes over. Whether it’s one en suite or a run of plots, the method is the same: remove, clean, prime where needed, then a neat new bead. Common call-outs are for gaps behind new kitchen upstands and sealant work across a run of new homes, on kitchens, skirting & floors and plot handovers.
Somewhere as small as St Mary Bourne, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
Our work is backed for twelve months.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What affects the quote in St Mary Bourne
We quote each job individually. This is what makes a difference:
- How many areas need sealing
- Mould in or behind the old joints
- Any working-time requirements on site
- Whether old sealant or filler has to be cut out
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
What to tell us for a quote
When you call or email, these details help:
- Photos by email, if that’s easy
- Where the property is
- The rough size of the job
- Any access issues, like height or stairs
Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand, and we’ll take it from there.
For landlords and businesses
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.

Keep an eye out for any of the following:
- Cracked sealant around new window and door frames
- Untidy sealant flagged on a snagging list
- Kitchen sealant that has pulled off the wall
- Shower seals failing in the first year or two

How do I get a quote for new build mastic in St Mary Bourne?

Where do you work from?

Will the old sealant be removed?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Different surfaces, different methods
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Joints are prepared properly before sealing.
Leave it or put it right?
A quick bead over the top of the old sealant can look fine at first, but it will not bond to the old layer. A lasting seal starts with removing the old one completely. In a small place like St Mary Bourne, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Ask us for a quote and we will explain what it covers.
