New build mastic for homes and businesses in Norcot
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. We work on skirting & floors, windows & doors and plot handovers, and common reasons people get in touch are beads laid onto grit and dust from the build and gaps behind new kitchen upstands.
Where new homes go up in smaller places like Norcot, it’s often a small development or a single plot. Each still needs its sealant and floor joints finished properly from day one.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Do you need new build mastic in Norcot?
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
Common reasons people contact us are:
- Beads laid onto grit and dust from the build
- Gaps between new skirting and floors
- Shower seals failing in the first year or two
- Sealant work across a run of new homes
Around Norcot, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before you book
- Whether they’re fully insured
- The length of the guarantee
- Which colour the sealant will be
- What preparation is included
How it works
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for most snagging lists, longer for a run of plots. A visit to Norcot is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Before we arrive
- Tell us if parking is tricky
- For business premises, tell us about site rules or sign-in
- Keep pets and children clear of the area while we work

New build mastic in Norcot: local notes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Get a leaking seal dealt with right away
- Photograph failed sealant before it’s redone
- Keep water off fresh sealant until it has cured
- Check bath and shower seals every few months as the house settles
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries and can be resealed later.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant.
For landlords and businesses
Letting agents and landlords in Norcot can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will quote.
What happens if it’s left?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. Around Norcot, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.

What the job involves on each surface
Plot handovers
Plot mastic is carried out to the developer’s schedule. Each joint is cleaned and primed where needed to keep callbacks down.
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. They get a flexible, water-resistant sealant.
