New Build Mastic in Ampfield
We cover Ampfield for plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly.
- Second-fix sealing on new plots
- Worktop and upstand sealant coming away
- Beads laid onto grit and dust from the build
Why act early in Ampfield
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote to plan around. Around Ampfield, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint generally makes the job bigger, not smaller. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us and we will give you an honest view and a quote.

About our new build mastic in Ampfield
Across Ampfield, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: cut out, clean, prime where needed and reseal neatly. If you have gaps opening as the house dries out and settles and gaps between new skirting and floors, we can help.
In a village or hamlet like Ampfield, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Each job carries a 12-month guarantee.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Ampfield: your questions answered
Will you come out to Ampfield?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you help a landlord with a rental near Chandlers Ford station?
Yes, we work for landlords and agents. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Ampfield, along with the rest of our area.
What does new build mastic cost?
It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or email us with a short description of the job.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
When is the best time to reseal in a new build?
It depends on whether water is getting through. A leaking shower or bath seal should be redone right away, while small cosmetic gaps can wait a while.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Movement caused by a poorly fitted tray or bath
- Cracking that points to a structural problem
- Leaking fittings rather than failed sealant
If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before booking.

- Leaking shower tray seals in a new home
- Sealant work across a run of new homes

How the job changes by surface
Skirting and floors
Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.
Plot handovers
Developers can send the plot schedule and specification. We seal bathrooms, kitchens, frames and floors to the agreed spec.
What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most snagging lists, longer for a run of plots, and the area is left clean. For a village or hamlet like Ampfield, 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 go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you’re given the cure time.
How to prepare
- Mention any leaks or damp you’ve noticed
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height
