New-build mastic & snagging in Farlington, Portsmouth
New-build sealant joints in Farlington need attention? We cut out the old, prepare the joints and apply the right sealant.
- Shower seals failing in the first year or two
- Skirting joints opening in the first winter
- Plot mastic for developers ahead of handover
New build mastic in Farlington, done properly
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover. Typical jobs include skirting joints opening in the first winter and sealant applied over dusty or wet surfaces, across bathrooms & en suites, windows & doors and skirting & floors.
Where new homes go up in smaller places like Farlington, it’s often a small development or a single plot. The sealant around baths, showers, frames and skirtings needs to be right from the start.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Why it’s worth doing now in Farlington
The builder is usually the first port of call while the snagging or warranty period runs. If it keeps failing or isn’t dealt with, we can reseal it properly. Homes in smaller places like Farlington can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
Why us?
- 20+ years of sealant experience

What affects the cost of new build mastic
For a quick quote, just ask. The main things that affect it are:
- The number and length of the joints

- How many rooms, windows or areas are involved
We don’t 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 email us.

How the visit works
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for most snagging lists, longer for a run of plots. In a smaller place like Farlington, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Preparing for the visit
- On commercial sites, let us know about site rules
- Clear the area around the work
- Tell us if parking is tricky

Advice
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Joints and finishes in Farlington homes
Farlington is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In and around Farlington, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

When to call us in Farlington
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and can tear.
These are the problems we’re asked about most:
- Plot mastic for developers ahead of handover
- Frame joints opening as the plaster dries
- Beads laid onto grit and dust from the build
- Gaps behind new kitchen upstands
If you’ve bought a new home near Cosham station, the sealant around baths, showers and frames is worth checking in the first year or two.

Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Record problems with dated pictures
- Keep water off fresh sealant until it has cured
- Check bath and shower seals every few months as the house settles
- Wipe joints with warm soapy water
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day.
Report failed sealant to the builder while you are in the snagging period. Once it ends, the repair may be down to you.

How long does the job take?
It depends on the size of the job, but as a guide it takes a few hours for most snagging lists, longer for a run of plots. We will give you a better idea when we quote.
