Lamarsh New Build Mastic
Plot mastic for developers and snagging failed sealant in new homes for homeowners, landlords and businesses in Lamarsh. Fully insured, ARBOMaster approved and guaranteed for a year.
- Beads laid onto grit and dust from the build
- Internal frame sealant that has split
- Shower seals failing in the first year or two
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Raise failed sealant with the developer while you’re covered
- Don’t wait for the house to settle if water is getting through
- Look at the sealant regularly in the first couple of years
- Avoid scourers and strong chemicals on sealant
Do not stand on the bath edge or the lip of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
About our new build mastic in Lamarsh
Dust is the enemy of 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. Typical jobs include gaps opening as the house dries out and settles and leaking shower tray seals in a new home, on show homes, windows & doors and kitchens.
Older homes in small places like Lamarsh often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
All of our work is guaranteed for twelve months, in Lamarsh and everywhere else we cover.

When to call us in Lamarsh
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly and cracked sealant shows up.
People normally contact us when they notice one of these:
- Cracks appearing as a new home settles
- Cracked caulk along new skirting
- Plot mastic for developers ahead of handover
- Kitchen sealant that has pulled off the wall
For new homes near Bures station, it’s worth checking the sealant early, while snags are still fresh.
What your quote should include
- How long the guarantee is

- What happens if the job turns out different
- What the cure time is
What affects the cost of new build mastic
We quote each job individually. These are the things that affect it:
- The number and length of the joints
- How many rooms, windows or areas are involved
- Which sealant suits the joint
- Mould in or behind the old joints
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
What to tell us for a quote
You do not need to know the technical terms. It helps if you can tell us:
- Pictures of the joints, sent by email
- Where the job is, and your postcode
- How we’d reach the joints
- Roughly how big the job is
We do not publish a price list. Instead, we give you a clear price for your job. To arrange one, phone 0345 464 0079 or drop us an email.
How the visit works
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Lamarsh, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can

Asking for a quote is easy: let us know the job and the location and its rough size. Photos by email help us understand the job.
Advice
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

When it is not the sealant
