- Shower seals failing in the first year or two
- Sealant that never bonded to the surface
- Skirting joints opening in the first winter
- Cracked sealant around new window and door frames
In and around Fleet Marston, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How we handle new build mastic in Fleet Marston
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a seal that’s letting water through needs doing now. Typical jobs include cracked caulk along new skirting and internal frame sealant that has split, on skirting & floors, windows & doors and show homes.
Somewhere as small as Fleet Marston, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Our work is backed for twelve months.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Follow the cure time we give you
- Raise failed sealant with the developer while you’re covered
- Photograph failed sealant before it’s redone
- Do not seal over failed sealant yourself
Follow the cure time we give you before the area gets wet. Silicone is usually left for about a day.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you.

What sealant work can’t fix
Sealant is not the answer to every problem, and we will tell you before we start. Sealant won’t put right:
- Baths and trays that move too much for sealant to cope with
- Your warranty claim itself, which is between you and the builder
- Damaged fittings that need replacing
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.

DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What affects the cost of new build mastic
We quote each job individually. This is what makes a difference:
- Which sealant suits the joint
- The number and length of the joints
- Whether old sealant or filler has to be cut out
- The number of rooms or windows
What it costs depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts.
What to tell us for a quote
To help us quote quickly, please include:
- Whether it has been sealed before
- Where the property is
- Photos by email, if that’s easy
- What the problem is, such as mould, gaps, leaks or cracking
To get a quote, call 0345 464 0079 or email us with the location and a short description of the problem. We will send you a clear quote before any work starts.
