What the job involves on each surface
Skirting and floors
Wet-area floor joints need a flexible seal. We seal them with a sealant suited to wet areas.
Kitchens
Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. We reseal them with a flexible sealant.
New build mastic in South Newington
Across South Newington, 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: cut out, clean, prime where needed and reseal neatly. If you have sealant that never bonded to the surface and shower seals failing in the first year or two, we can put it right.
Somewhere as small as South Newington, 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.
Whatever the size of the job, you get the same one-year guarantee in South Newington and across Oxfordshire.

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Photograph failed sealant before it’s redone
- Look at the sealant regularly in the first couple of years
- Keep water off fresh sealant until it has cured
- Do not wait for the house to settle if water is getting through
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak.
How the visit works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours for most snagging lists, longer for a run of plots. In a small place like South Newington, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely down to clean surfaces.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky
- For indoor joints, keep the area dry beforehand if you can

What we cannot put right
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Broken tiles or a split tray
- Structural cracks in walls or ceilings
- Movement caused by a poorly fitted tray or bath
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before you book.
Surfaces we seal
- Plot handovers
- Windows & doors
- Bathrooms & en suites
- Kitchens
- Skirting & floors
- Show homes
Common problems we fix in South Newington
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint.
These are the problems we are asked about most:
- Second-fix sealing on new plots
- Skirting joints opening in the first winter
- Kitchen sealant that has pulled off the wall
- Sealant applied over dusty or wet surfaces
In and around South Newington, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Why act early in South Newington
Small cosmetic gaps can wait for the house to settle, but water getting through can’t. Not sure whether yours can wait? You can ring 0345 464 0079 or send us an email with a few pictures and we will give you a straight answer. Around South Newington, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Is it normal for sealant to crack in a new home?
New homes dry out and move in their first couple of years, and sealant is often rushed onto dusty, unprimed surfaces. Either can make it fail early.
