It’s worth asking for a quote if you see:
- Gaps opening as the house dries out and settles
- Messy sealant that spoils new finishes
- Gaps between new skirting and floors
- Kitchen sealant that has pulled off the wall
In and around Nether Worton, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

New build mastic for homes and businesses in Nether Worton
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover with a sealant suited to each area. We work on show homes, windows & doors and plot handovers, and common reasons people get in touch are plot mastic for developers ahead of handover and new-build shower sealant that has already split.
In a village or hamlet like Nether Worton, 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.
There’s a 12-month guarantee on every job, large or small.

What happens if it’s left?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it won’t bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. Older cottages and farmhouses around Nether Worton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.

Landlord and commercial work in Nether Worton
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
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.
Can I do it myself?
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. Everything old must be removed first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

How it works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take anything from a few hours to several days, depending on the number of plots. Somewhere as small as Nether Worton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work through your snagging list or plot schedule with you.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.
How to prepare
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises
- Keep children and pets away from the work area

Advice
Common questions in Nether Worton
Do you work for landlords with property near Heyford station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Is Nether Worton in your area for new build mastic?
Yes, Nether Worton is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses, and we’re fully insured.
Do you use white or clear sealant?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before we start.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Can I add another job to the visit?
Of course. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access.
