Do you need new build mastic in Bishopstoke?
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
Any of these means the joints need attention:
- Plot mastic for developers ahead of handover
- Beads laid onto grit and dust from the build
- Cracked sealant around new window and door frames
- Gaps behind new kitchen upstands
For new homes near Eastleigh station, it’s worth checking the sealant early, while snags are still fresh.

New build mastic in Bishopstoke
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. We work on kitchens, plot handovers and show homes, and people most often call us about beads laid onto grit and dust from the build and leaking shower tray seals in a new home.
In and around Bishopstoke, floors range from older timber boards to tiles and newer finishes, each moving in its own way. Skirting and threshold joints need a sealant that suits the floor.
Our work is backed for twelve months, in Bishopstoke and everywhere else we cover.

Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
The process
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for most snagging lists, longer for a run of plots. For a job in Bishopstoke, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- Each joint is checked for movement before any work starts.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- Tell us about any water getting in
- Let us know about parking restrictions
- For indoor joints, keep the area dry beforehand if you can

Common questions in Bishopstoke
Is Bishopstoke within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Eastleigh station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Do you guarantee your work?
Yes. Every job comes with a 12-month guarantee.
How much does new build mastic cost in Bishopstoke?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before work begins.
Should I go to my builder first?
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.
Can you do plot mastic on a new development?
Yes. We take on second-fix sealant work across new plots. We clean and prime joints properly to keep callbacks down.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Honest limits
It helps to know what we can’t do too:
- Disputes or warranty claims with your builder
- Damaged fittings that need replacing
- Leaks from pipes, valves or wastes, which need a plumber
If in doubt, call 0345 464 0079 or send us an email and we will say what we think before booking.

What affects the quote in Bishopstoke
We do not publish a price list. The quote depends on:
- The number of rooms or windows
- How easy the joints are to reach
- The old material and how stubborn it is
- Which sealant suits the joint
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 play a part, and we will explain the quote if you ask.
What we need to know
When you call or email, it’s useful to know:
- The rough size of the job
- If it’s domestic, commercial or a hotel
- Whether it has been sealed before
- What the problem is, such as mould, gaps, leaks or cracking
For a quick quote, get us on the phone, or email us if that’s easier. Tell us about the joints that need doing and we will explain what’s involved and send you a clear quote.

How the job changes by surface

En suite showers are a common source of leaks into the room below. A proper reseal keeps water in the tray.
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.
