New build mastic for homes and businesses in Lydd-on-Sea
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you are still within the builder’s snagging or warranty period, tell them first. If you have leaking shower tray seals in a new home and gaps behind new kitchen upstands, we can help, whatever the surface.
In a village or hamlet like Lydd-on-Sea, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Each job carries a 12-month guarantee, whatever its size.

Lydd-on-Sea questions
What guarantee comes with new build mastic in Lydd-on-Sea?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Is Lydd-on-Sea within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
My new home is still under warranty. Should I contact you?
If you are still within the builder’s snagging or warranty period, report it to them first. If they’re slow or the fix does not last, we can help.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
What does new build mastic cost?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before we start.
Can new sealant go on top of the old bead?
No. New silicone will not bond to old silicone, so sealing over the top fails quickly. The old sealant always comes out first.
Can you match the sealant colour to my new kitchen or bathroom?
White and clear are the most common, but other colours are available. We match the colour to the finish.
Aftercare tips
Aftercare is simple:
- Resist patching a failed seal with a tube from the DIY shop
- Get a leaking seal dealt with straight away
- Use the extractor fan every time you shower
- Keep photos and emails about snagging items
Watch the joints as the house settles. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.
Early snagging is easier snagging. Left alone, a small crack can become a leak over time.
Surface by surface
Windows and doors
Draughts around new frames are often a sealant gap. We check and reseal the frame edges.
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.
How we quote for new build mastic
The price is agreed before any work begins. It takes into account:
- The size of the job
- How much old sealant there is and how hard it is to remove
- The product the joint needs
- Access and height

What we need to know
When you call or email, it’s useful to know:
- A few photos by email, if you can
- Roughly how big the job is
- The problem you’ve noticed
- How we’d reach the joints
Getting a quote is simple: let us know the job and the location and its rough size. Photos by email help us understand the job.
What new build mastic looks like in Lydd-on-Sea
Lydd-on-Sea is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In and around Lydd-on-Sea, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

When it isn’t the sealant

The process
Every visit runs the same way: we check the joints, protect the area around them, do the work and tidy away. It normally takes a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Lydd-on-Sea, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out.
- 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 any water getting in
- Let us know about earlier repairs to the joints
- Mention any tricky access

Advice
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
