About our new build mastic in Sarisbury
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. If you are dealing with worktop and upstand sealant coming away and shower seals failing in the first year or two, we can put it right, whatever the surface.
For a new home in or near Sarisbury, it’s worth checking the sealant early. Common snags include open skirting joints, lifting shower seals and gaps around frames.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

Quotes for new build mastic in Sarisbury
You will get a clear quote before work begins. It’s based on:
- How many areas need sealing
- How much there is to do
- When we can work, for business premises
- Mould in or behind the old joints
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Helping us quote
What to tell us when you ask for a quote:
- Where the job is, and your postcode
- Any previous sealing or DIY work
- What’s wrong with the joints now
- How we’d reach the joints
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
When it is not the sealant
We won’t take on work that will not last, so these are the limits:
- A tray or bath that is not properly supported, until it’s fixed
- Leaking fittings rather than failed sealant
- Broken tiles or a split tray
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.
What we seal
- Plot handovers
- Bathrooms & en suites
- Kitchens

How it works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes a few hours in a single home, including the tidy-up. Parking around Sarisbury is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises
- Let us know about earlier repairs to the joints

Advice
For landlords and businesses
We work for letting agents and landlords as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
When to call us in Sarisbury
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.
Keep an eye out for any of the following:
- Cracks appearing as a new home settles
- Untidy sealant flagged on a snagging list
- Gaps behind new kitchen upstands
- Skirting joints opening in the first winter
For new homes near Swanwick station, it’s worth checking the sealant early, while snags are still fresh.

How the job changes by surface
Show homes
We seal show-home bathrooms, kitchens and frames ready for viewings. Tell us when the home is open so we can plan around it.
Skirting and floors
Wet-area floor joints need a flexible seal. We seal them with a sealant suited to wet areas.
DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Joints and finishes in Sarisbury homes
Sarisbury is within about 2 miles of the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. 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.
Around Sarisbury, as everywhere, new build mastic is only as good as the preparation behind it.
