New build mastic in Goodworth Clatford, done properly
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first. We work on bathrooms & en suites, windows & doors and plot handovers, and common reasons people get in touch are cracks appearing as a new home settles and untidy sealant flagged on a snagging list.
Older homes in small places like Goodworth Clatford often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

Do you need new build mastic in Goodworth Clatford?
A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open.
These are the problems we are asked about most:
- Plot mastic for developers ahead of handover
- Sealant that never bonded to the surface
- Cracks appearing as a new home settles
- Cracked caulk along new skirting
Around Goodworth Clatford, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before booking
- Is the old sealant removed completely?
- Whether VAT is included
- What preparation is included
- What product goes in the joint
DIY sealant or a professional job?
If you’re set on DIY, put the effort into 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.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

What the job involves on each surface
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Show homes
In a show home, the sealant is on display. Every bead is neat and coloured to suit the room.
How it works
There is not much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes a few hours in a single home, including the tidy-up. For a village or hamlet like Goodworth Clatford, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely, with no layer left behind.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Mention any parking rules near the property
- Let us know about earlier repairs to the joints

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Look at the sealant regularly in the first couple of years
- Keep photos and emails about snagging items
- Don’t seal over failed sealant yourself
- Use the extractor fan every time you shower
Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.

Your questions about new build mastic in Goodworth Clatford
Is Goodworth Clatford in your area for new build mastic?
Yes, Goodworth Clatford is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear price.
Do you cover smaller places like Goodworth Clatford?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can new sealant go on top of the old bead?
No. The old sealant is cut out fully, the joint cleaned and primed where needed, before resealing.
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 tell you when we quote.
Do you work for landlords and businesses?
Yes, regularly. Several properties can be quoted together.
Where do you work from?
Mr Mastic is based in Crawley. We cover Goodworth Clatford and the rest of Hampshire, along with the rest of our area.
What colour sealant will you use?
That depends on what the joint meets: white or clear for most sanitary joints, colours for worktops, floors and frames. We will agree it with you first.
Why has my new-build shower seal failed already?
There are normally two causes: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
Work for landlords, hotels and businesses
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.
In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
