About our new build mastic in Sibford Ferris
Snagging sealant properly means taking the failed bead out completely. New silicone won’t bond to old silicone, so the joint is cut out, cleaned, dried and resealed. We work on plot handovers, skirting & floors and windows & doors, and people most often call us about worktop and upstand sealant coming away and joints pulling apart as timber shrinks.
For a small place like Sibford Ferris, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
Whatever the size of the job, it’s backed by our 12-month guarantee in Sibford Ferris and across Oxfordshire.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

How the job changes by surface
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk.
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We take it out and reseal neatly, colour-matched where it shows.
Why act early in Sibford Ferris
Small cosmetic gaps can wait for the house to settle, but water getting through cannot. If you’re unsure which you have, ring 0345 464 0079 or drop us an email with pictures and we will give you a straight answer. Around Sibford Ferris, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit usually makes better use of the time than several visits. We will give you a clear quote for the lot.

Is there a guarantee on new build mastic in Sibford Ferris?
All our work, in Sibford Ferris and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Do you have insurance?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
How long does new build mastic take?
A typical job takes a few hours for most snagging lists, longer for a run of plots, including the preparation. We will confirm how long when we quote.
Is there any odour?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
My new home is still under warranty. Should I contact you?
Your builder, if you are still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it and our work is guaranteed for a year.

Looking after it afterwards
Looking after new joints is easy:
- Keep pictures and emails about snagging items
- Keep water off fresh sealant until it has cured
- Put sealant faults on your snagging list early
- Clean sealant with mild detergent, not abrasives
Keep pictures of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
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.
When to call us in Sibford Ferris
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly and cracks appear in the sealant.
People normally contact us after spotting something like this:
- Beads laid onto grit and dust from the build
- Smeared, uneven beads picked up at snagging
- Frame joints opening as the plaster dries
- Worktop and upstand sealant coming away
Whether the job is in Sibford Ferris itself or nearby, the right material for each joint matters as much as a neat finish.
