New build mastic in Alkham, done properly
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. We’re often asked to deal with skirting joints opening in the first winter and leaking shower tray seals in a new home, across windows & doors, kitchens and show homes.
For a small place like Alkham, the journey and access are planned in advance, and the work itself is the same as on any site.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

What we cannot put right
We will always be straight with you, so here’s what new sealant will not do:
- Structural cracks in walls or ceilings
- Deciding who is responsible under a builder’s warranty
- Plumbing faults behind the sealant
If you’re not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer.
Surfaces we seal
- Show homes
- Skirting & floors
- Kitchens
- Bathrooms & en suites
- Windows & doors
- Plot handovers
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Don’t seal over failed sealant yourself
- Keep water off fresh sealant until it has cured
- Do not wait for the house to settle if water is getting through
- Raise failed sealant with the developer while you’re covered
Follow the cure time we give you before the area gets wet. Silicone is usually left for about a day before water reaches them.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.

What the job involves on each surface
Windows and doors
Draughts around new frames are often a sealant gap. We check and reseal the frame edges.
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.
Why deal with it now?
DIY kits do not solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Where a wall is exposed, as many are in small places like Alkham, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.

When to call us in Alkham
Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints are not always given time to dry before the sealant goes on.
If you can see any of these, it’s time to have the joints looked at:
- Beads laid onto grit and dust from the build
- Cracks appearing as a new home settles
- Cracked sealant around new window and door frames
- Smeared, uneven beads picked up at snagging
For new homes near Kearsney station, it’s worth checking the sealant early, while snags are still fresh.
