New build mastic in Hastoe
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that is reasonable, but a failed shower or bath seal shouldn’t wait. If you have smeared, uneven beads picked up at snagging and sealant work across a run of new homes, we can help, whatever the surface.
In a village or hamlet like Hastoe, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
There’s a 12-month guarantee on every job.

How to look after the new joints
So the new joints stay in good condition:
- Record problems with dated photos
- Look at the sealant regularly in the first couple of years
- Report sealant problems to your builder during the snagging period
- Resist patching a failed seal with a tube from the DIY shop
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries.
Don’t let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you.
Different surfaces, different methods
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.
Show homes
We can refresh show-home sealant that has discoloured or been knocked. We cut it out and reseal neatly.
How it works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Hastoe, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked for movement before any work starts.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Clear items away from the joints we are working on
- Mention any tricky access

Related advice
Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Why it’s worth doing now in Hastoe
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. Where a wall is exposed, as many are in small places like Hastoe, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first.

Common problems we fix in Hastoe
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly and cracked sealant shows up.
The most common problems we see are:
- Gaps behind new kitchen upstands
- Beads laid onto grit and dust from the build
- Cracked sealant around new window and door frames
- Cracked caulk along new skirting
Around Hastoe, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before booking
- Who turns up on the day
- Is the old sealant removed completely?
- Are they insured?
- The length of the guarantee
When something else is needed
To be straight with you, there are a few things sealant will not fix:
- Cracking that points to a structural problem
- Leaking fittings rather than failed sealant
- Baths and trays that move too much for sealant to cope with
If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer.
