New Build Mastic in North Newington
Our applicators work in North Newington on plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly.
- Sealant applied over dusty or wet surfaces
- Shower seals failing in the first year or two
- Sealant work across a run of new homes
About our new build mastic in North Newington
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 sealant actually sticks instead of bonding to the dust. We work on bathrooms & en suites, plot handovers and show homes, and people most often call us about second-fix sealing on new plots and messy sealant that spoils new finishes.
Around North Newington, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What we are called out for in North Newington
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly.
Any of these means the joints need attention:
- Gaps between new skirting and floors
- Leaking shower tray seals in a new home
- Kitchen sealant that has pulled off the wall
- Sealant that never bonded to the surface
In and around North Newington, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Sealant isn’t the answer to every problem, and we’ll tell you before any work starts. Sealant will not put right:
- Cracking that points to a structural problem
- Cracked trays, tiles or worktops
- Leaks from pipes, valves or wastes, which need a plumber

How the visit works
When we arrive, we look over the joints with you first, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. The work normally takes a few hours in a single home. Somewhere like North Newington needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided 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.
- 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.
- We tool every joint neatly and tell you when each area can be used.
Getting ready for the visit
- Mention if the joints have been sealed before
- Let us know if you’ve seen damp or leaks
- For indoor joints, keep the area dry beforehand if you can

What the job involves on each surface
Plot handovers
Taking time over preparation reduces return visits. We clean out building dust before sealing and prime where the product needs it.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Landlord and commercial work in North Newington
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will quote.
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
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.
