New build mastic in Rose Hill, done properly
Across Rose Hill, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: cut out, clean, prime where needed and reseal neatly. If you have leaking shower tray seals in a new home and sealant that never bonded to the surface, we can put it right.
In a village or hamlet like Rose Hill, 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.
We stand behind the work with a 12-month guarantee.

New build mastic in Rose Hill: local notes

Why it’s worth doing now in Rose Hill
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. Around Rose Hill, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.

What we do, step by step
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and tidy away. It normally takes anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Rose Hill, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit

Do you work for landlords with property near Uckfield station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Can I send you my snagging list?

Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
What does new build mastic cost?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or email us and let us know what needs doing and where.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Is there any odour?
Some sealants have a smell while they cure. Opening a window helps.
Is there a guarantee?
Yes, always. There’s a 12-month guarantee on every job, wherever you are.
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Do you need new build mastic in Rose Hill?
On many sites, sealant goes on in the final rush before handover. Joints aren’t always cleaned of dust or primed, so the bead never bonds properly.
The most common problems we see are:
- Messy sealant that spoils new finishes
- Worktop and upstand sealant coming away
- Second-fix sealing on new plots
- Skirting joints opening in the first winter
In and around Rose Hill, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What your quote should include
- What the cure time is
- What the quote includes, VAT included or not
- Whether you can choose the colour
- Is the old sealant removed completely?
How the job changes by surface
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out with baths filled first.
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We take it out and reseal neatly, colour-matched where it shows.
