New build mastic in Filching
Snagging sealant properly means taking the failed bead out completely. Fresh silicone can’t bond to the old layer, so the joint is cut out, cleaned, dried and resealed. We work on kitchens, windows & doors and skirting & floors, and common reasons people get in touch are sealant applied over dusty or wet surfaces and untidy sealant flagged on a snagging list.
For a small place like Filching, the journey and access are planned in advance, and the work itself is the same as on any site.
A one-year guarantee comes as standard.

Different surfaces, different methods
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.
What happens on the day
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Filching, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.

My new home is still under warranty. Should I contact you?
Start with your builder while their snagging or warranty period runs. After that, or if their repair keeps failing, we can do it.
What colour sealant will you use?
That depends on what the joint meets: white or clear for most sanitary joints, colours for worktops, floors and frames. We’ll agree it with you first.
Can I send you my snagging list?
Yes. We often work straight from a snagging list. We agree the sealant items with you before work begins.
Aftercare tips
To keep the joints looking good and working properly:
- Record problems with dated pictures
- Put sealant faults on your snagging list early
- Check bath and shower seals every few months as the house settles
- Wait for the cure time before using a resealed shower
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant and protects the rest of the house.

When to call us in Filching
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly.
Common reasons people contact us are:
- Gaps behind new kitchen upstands
- Shower seals failing in the first year or two
- Beads laid onto grit and dust from the build
- Cracked caulk along new skirting
In and around Filching, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before booking
- How long the guarantee is
- Whether they’re fully insured
- How much experience the applicator has
- What the quote includes, VAT included or not
Why deal with it now?
A tube of sealant from the DIY shop will not fix the cause: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. Around Filching, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
