Leave it or put it right?
The builder is normally the first port of call while the snagging or warranty period runs. If it keeps failing or isn’t dealt with, we can reseal it properly. Around Shilton, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.

New build mastic in Shilton, done properly
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so the joint is cut out, cleaned, dried and resealed. We work on skirting & floors, plot handovers and windows & doors, and people most often call us about gaps opening as the house dries out and settles and cracked sealant around new window and door frames.
Older homes in small places like Shilton often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Big or small, you get the same 12-month guarantee in Shilton and across Oxfordshire.

Work for landlords, hotels and businesses
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

Related advice
Signs you need new build mastic in Shilton
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart, and sealant that cannot keep up splits.
It’s worth asking for a quote if you see:
- Joints pulling apart as timber shrinks
- Internal frame sealant that has split
- Worktop and upstand sealant coming away
- Beads laid onto grit and dust from the build
In and around Shilton, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Before booking anyone
- Are they insured?
- Whether VAT is included
- Who turns up on the day
- Is the old sealant removed completely?
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
When something else is needed
It helps to know what we cannot do too:
- Broken tiles or a split tray
- Leaks from pipes, valves or wastes, which need a plumber
- Cracking that points to a structural problem
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before you book.
Surfaces we seal
- Show homes
- Windows & doors
- Bathrooms & en suites
- Plot handovers
- Skirting & floors
- Kitchens
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Keep photos and emails about snagging items
- Clean sealant with mild detergent, not abrasives
- Open a window or run the fan after bathing
- Act quickly if a seal starts to leak
Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
