New build mastic for homes and businesses in Ashley Heath
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. We work on kitchens, plot handovers and windows & doors, and people most often call us about internal frame sealant that has split and sealant work across a run of new homes.
If you’ve bought a new home in or near Ashley Heath, the first year or two is a good time to check the sealant. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Do you need new build mastic in Ashley Heath?
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
Look out for these signs:
- Internal frame sealant that has split
- Plot mastic for developers ahead of handover
- Gaps behind new kitchen upstands
- Gaps opening as the house dries out and settles
In and around Ashley Heath, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Kitchens
New-kitchen sealant is often applied in a rush. We remove it and reseal with a kitchen-suitable sealant.
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. We reseal once the old bead is fully out with baths filled first.
What happens if it’s left?
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote for the lot. Homes in smaller places like Ashley Heath can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.

How we quote for new build mastic
We do not publish a price list, because no two jobs are the same. What we look at:
- Whether there’s mould to deal with
- How much old sealant there is and how hard it is to remove
- The type of sealant required
- Access and height
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts.
Asking for a quote
What to tell us when you ask for a quote:
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
- How many joints, rooms or windows are involved
- Photos by email, if that’s easy
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. When it suits you, call 0345 464 0079 or send us an email.
How to look after the new joints
Looking after new joints is easy:
- Report sealant problems to your builder during the snagging period
- Check bath and shower seals every few months as the house settles
- Keep water off fresh sealant until it has cured
- Avoid scourers and strong chemicals on sealant
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing.
Early snagging is easier snagging. Small faults turn into leaks if left in a busy bathroom.

What we do, step by step
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for most snagging lists, longer for a run of plots. Parking around Ashley Heath is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- Each joint is checked for movement before any work starts.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
