New-build mastic & snagging in Bushey Heath, Hertfordshire
New build mastic in Bushey Heath from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.

- Frame joints opening as the plaster dries
DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
About our new build mastic in Bushey Heath
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, skirting & floors and bathrooms & en suites, and the jobs we see most are gaps opening as the house dries out and settles and sealant work across a run of new homes.
In and around Bushey Heath, floors range from older timber boards to tiles and newer finishes, from timber that moves with the seasons to tiles laid on concrete. Skirting and threshold joints need a sealant that suits the floor.
We stand behind the work with a 12-month guarantee, so you are covered after we have gone.

Why deal with it now?
A hairline gap at a skirting can wait, but a leaking seal cannot. If you’re unsure which you have, call 0345 464 0079 or email us with photos and we’ll tell you. Around Bushey Heath, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first.

- Fully insured
- Anti-fungal silicone where joints get wet

How the job changes by surface
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Each joint is cleaned and primed where needed to keep callbacks down.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Keep pictures and emails about snagging items
- Open a window or run the fan after bathing
- Avoid running a DIY bead over the old one
- Put sealant faults on your snagging list early
Watch the joints as the house settles. Small gaps can appear as the house dries.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in saves a harder job later.
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most snagging lists, longer for a run of plots, and the area is left clean. In a smaller place like Bushey Heath, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Let us know about earlier repairs to the joints
- Clear items away from the joints we are working on
