New build mastic in Oxhey
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over using the right product for each joint. We work on plot handovers, skirting & floors and bathrooms & en suites, and the jobs we see most are sealant that never bonded to the surface and kitchen sealant that has pulled off the wall.
If you’ve bought a new home in or near Oxhey, the first year or two is a good time to check the sealant. Common snags include open skirting joints, lifting shower seals and gaps around frames.
You get a 12-month guarantee, the same in Oxhey as everywhere else we work.

Landlord and commercial work in Oxhey
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Don’t seal over failed sealant yourself
- Wipe joints with warm soapy water
- Report sealant problems to your builder during the snagging period
- Get a leaking seal dealt with straight away
Do not stand on the bath edge or the lip of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and the new finishes intact.
What affects the quote in Oxhey
We do not publish a price list. The quote depends on:
- When we can work, for business premises
- The size of the job
- Access and height
- The old material and how stubborn it is
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.
Asking for a quote
What to tell us when you ask for a quote:
- Where the job is, and your postcode
- How we’d reach the joints
- The rough size of the job
- Any previous sealing or DIY work
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. Whenever you are ready, ring 0345 464 0079 or send us an email.
What else we do in Oxhey
Why act early in Oxhey
DIY kits do not solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. Around Oxhey, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Why book with us
- Homes, businesses and hotels
- We never seal over old sealant
- You choose the colour before work begins
- Anti-fungal sanitary silicone in wet areas
Common problems we fix in Oxhey
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly.
Most people get in touch after spotting something like this:
- Gaps behind new kitchen upstands
- Beads laid onto grit and dust from the build
- Sealant work across a run of new homes
- Cracked caulk along new skirting
Around Oxhey, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before booking
- Whether you can choose the colour
- Whether the sealant suits the joint
- Is the old sealant removed completely?
- Are they insured?
Different surfaces, different methods
Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there, food-safe where it’s needed.
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.
Joints and finishes in Oxhey homes
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For new homes near Bushey station, it’s worth checking the sealant early, while snags are still fresh.
