New build mastic in Whitsbury, done properly
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. We are often asked to deal with frame joints opening as the plaster dries and sealant that never bonded to the surface, on bathrooms & en suites, skirting & floors and plot handovers.
Older homes in small places like Whitsbury often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
There’s a 12-month guarantee on every job.

Do you need new build mastic in Whitsbury?
Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used.
Most people get in touch after spotting one of these:
- Frame joints opening as the plaster dries
- Untidy sealant flagged on a snagging list
- Gaps between new skirting and floors
- Sealant that never bonded to the surface
Around Whitsbury, as everywhere, new build mastic is only as good as the preparation behind it.

What else we do in Whitsbury
What affects the quote in Whitsbury
The price is agreed before any work begins. It takes into account:
- Which sealant suits the joint
- How many areas need sealing
- Access and height
- When we can work, for business premises
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Ask us for a quote and we will explain what it covers.
What we need to know
To make quoting easier, let us know:
- How we’d reach the joints
- Roughly how big the job is
- Where the job is, and your postcode
- Any previous sealing or DIY work
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is.
DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Common questions in Whitsbury
Can you do new build mastic in Whitsbury?
Yes. We work across London and the South East, and Whitsbury is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
Will you come out to Whitsbury?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can I send you my snagging list?
Yes. We often work straight from a snagging list. We agree the sealant items with you before any work starts.
When is the sealant fully cured?
It depends on the product and the temperature. Before we leave, we’ll tell you the cure time.
Is there any odour?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Is the work guaranteed?
Yes, always. Each job is guaranteed for twelve months, large or small.
Surface by surface
Kitchens
Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. A fresh flexible bead closes them.
Skirting and floors
Gaps under skirting are one of the most common new-build snags. We seal it with a flexible sealant that copes with the movement.
New homes and floors in Whitsbury
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Whether the job is in Whitsbury itself or nearby, the right material for each joint matters as much as a neat finish.

What happens on the day
Before we leave, we go over the finished joints with you. The work normally takes a few hours for most snagging lists, longer for a run of plots, depending on the size of the job. In a small place like Whitsbury, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- Mention any tricky access
- Tell us about any water getting in
- Plan for the work area to be out of bounds to pets and children
