Do you need new build mastic in Hastigrow?
A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart and the sealant has to cope with the movement.
Signs it’s time to call us include:
- Cracks appearing as a new home settles
- Beads laid onto grit and dust from the build
- Second-fix sealing on new plots
- Untidy sealant flagged on a snagging list
For jobs in and around Hastigrow, choosing the right material for each joint is as important as a tidy finish.

About our new build mastic in Hastigrow
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. We work on windows & doors, bathrooms & en suites and kitchens, and the jobs we see most are worktop and upstand sealant coming away and sealant applied over dusty or wet surfaces.
Around smaller Scottish places like Hastigrow, new homes tend to be single plots or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
There’s a 12-month guarantee on every job, whatever its size.

What else we do in Hastigrow
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Wipe joints with warm soapy water
- Do not wait for the house to settle if water is getting through
- Avoid running a DIY bead over the old one
- Keep pictures and emails about snagging items
Avoid standing on the rim of the bath or the edge of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you.
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The process
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It generally takes a few hours for most snagging lists, longer for a run of plots. Somewhere like Hastigrow may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- 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.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you’re given the cure time.
Getting ready for the visit
- Mention any tricky access
- Mention any leaks or damp you’ve noticed
- Where the joints are inside, avoid wetting them before we arrive

Do you cover Hastigrow for new build mastic?

Where are you based?
We work from Crawley. Our applicators cover Hastigrow, along with the rest of our area.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
Is there any odour?
Some sealants have a smell while they cure. Ventilation helps.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and you will get one quote.
Is it normal for sealant to crack in a new home?
A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.
Why it’s worth doing now in Hastigrow
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

What we cannot put right

- Cracking that points to a structural problem
- Leaks from pipes, valves or wastes, which need a plumber
- Damaged fittings that need replacing
