Who should fix failed sealant in a new build?
Start with the builder if you’re in the snagging or warranty period. Once that is done, or if they will not put it right, we will cut it out and reseal it.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we’re using and why.
Can you quote for more than one area?

New build mastic in Crockerhill, done properly
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. We work on kitchens, bathrooms & en suites and skirting & floors, and people most often call us about gaps opening as the house dries out and settles and smeared, uneven beads picked up at snagging.
Work in a small place like Crockerhill just needs the journey and access planning, and the work itself is the same as on any site.
Every job is covered by our 12-month guarantee.

DIY sealant or a professional job?
The difference is mostly in the preparation and the 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.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Surface by surface
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Skirting and floors
Wet-area floor joints need a flexible seal. They get a flexible, water-resistant sealant.
How to look after the new joints
Looking after new joints is easy:
- Avoid running a DIY bead over the old one
- Wait for the cure time before using a resealed shower
- Use the extractor fan every time you shower
- Report sealant problems to your builder during the snagging period
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing so moisture doesn’t sit on the sealant.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small.
What affects the cost of new build mastic
There’s no set price list, because no two jobs are the same. What we look at:
- The size of the job
- Access and height
- Working hours on commercial sites
- The number of rooms or windows
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.
Asking for a quote
What to tell us when you ask for a quote:
- What the problem is, such as mould, gaps, leaks or cracking
- How many joints, rooms or windows are involved
- How we’d reach the joints
- Pictures of the joints, sent by email
We quote each job on its own, so start by telling us what you need. Simply phone 0345 464 0079 or drop us an email and describe the job.
When it is not the sealant
We’d rather tell you now than do work that will not last, so these are the limits:
- Baths and trays that move too much for sealant to cope with
- Cracking that points to a structural problem
- 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 before booking.

What new build mastic looks like in Crockerhill
Crockerhill is close to 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For new homes near Fareham station, it’s worth checking the sealant early, while snags are still fresh. Around Crockerhill, as everywhere, new build mastic is only as good as the preparation behind it.
