Lower Pennington New Build Mastic
Our applicators work in Lower Pennington on plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly.
- Gaps opening as the house dries out and settles
- Kitchen sealant that has pulled off the wall
- Second-fix sealing on new plots
How it works
At the end, we look at the finished work together. The work normally takes a few hours for most snagging lists, longer for a run of plots, depending on the size of the job. For a village or hamlet like Lower Pennington, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- 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.
How to prepare
- Tell us about any water getting in
- For indoor joints, keep the area dry beforehand if you can
- Mention if the joints have been sealed before

How we handle new build mastic in Lower Pennington
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 windows & doors, plot handovers and bathrooms & en suites, and people most often call us about sealant that never bonded to the surface and leaking shower tray seals in a new home.
Older homes in small places like Lower Pennington often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Big or small, it’s backed by our one-year guarantee.

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.

Do you need new build mastic in Lower Pennington?
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
Signs it’s time to call us include:
- Second-fix sealing on new plots
- Leaking shower tray seals in a new home
- Frame joints opening as the plaster dries
- Sealant that never bonded to the surface
If you’ve bought a new home near Lymington Pier station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before you book
- What insurance they hold
- What the quote includes, VAT included or not
- How long the guarantee is
- What the cure time is
How to look after the new joints
After the cure time, these simple habits help:
- Get a leaking seal dealt with straight away
- Look at the sealant regularly in the first couple of years
- Raise failed sealant with the developer while you’re covered
- Ventilate bathrooms well, especially in the first year
Follow the cure time we give you before the area gets wet. Silicone is usually left for about a day.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
Surface by surface
Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Can I do it myself?
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 fails, we can still redo it.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What else we do in Lower Pennington
What we cannot put right
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- A tray or bath that isn’t properly supported, until it’s fixed
- Leaks from pipes, valves or wastes, which need a plumber
- Your warranty claim itself, which is between you and the builder
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly.
