New build mastic for homes and businesses in Fox
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. Typical jobs include gaps behind new kitchen upstands and smeared, uneven beads picked up at snagging, on show homes, bathrooms & en suites and skirting & floors.
Somewhere as small as Fox, 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.
Each job carries a 12-month guarantee, whatever its size.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Signs you need new build mastic in Fox
Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly, and the problem shows up after you move in.
The problems people normally mention when they call are:
- Gaps behind new kitchen upstands
- Sealant that never bonded to the surface
- Leaking shower tray seals in a new home
- Cracked sealant around new window and door frames
For new homes near Grateley station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before booking
- What the cure time is
- The length of the guarantee
- What product goes in the joint
- Whether you can choose the colour
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Watch for new gaps as the house dries out
- Photograph failed sealant before it’s redone
- Avoid scourers and strong chemicals on sealant
- Raise failed sealant with the developer while you’re covered
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it as they wear the bead.
Don’t let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you.
What happens on the day
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours in a single home. For a village or hamlet like Fox, 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.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you’re given the cure time.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Clear the area around the work
- For business premises, tell us about site rules or sign-in

What affects the quote in Fox
There’s no set price list. What we look at:
- Whether there’s mould to deal with
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
- How many rooms, windows or areas are involved
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.
What to tell us for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Where the job is, and your postcode
- If someone has resealed it before
- Whether it’s a home or a business
- Any access issues, like height or stairs

What happens if it’s left?
A tube of sealant from the DIY shop won’t fix the cause: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. In a small place like Fox, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or drop us an email and we’ll talk you through it.
