New build mastic for homes and businesses in Chilbolton
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. Both get the same care over preparation. Typical jobs include cracked caulk along new skirting and internal frame sealant that has split, across skirting & floors, bathrooms & en suites and kitchens.
For a small place like Chilbolton, the journey and access are planned in advance, and the work itself is the same as on any site.
Each job carries a 12-month guarantee, whatever its size.

What the job involves on each surface
Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there suited to the job.
Show homes
Show homes need sealant that looks right from day one. Every bead is neat and coloured to suit the room.
How the visit works
You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the job takes anything from a few hours to several days, depending on the number of plots for a typical job. In a small place like Chilbolton, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you’re given the cure time.
How to prepare
- Mention any tricky access
- Tell us about any water getting in
- Mention any parking rules near the property

Quotes for new build mastic in Chilbolton
We quote each job individually. These are the things that affect it:
- Access and height
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
- Which sealant suits the joint
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Asking for a quote is easy: let us know what needs doing and where. A few photos by email make the job easier to understand, and we will come back to you with a quote.

Signs you need new build mastic in Chilbolton
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and the sealant may split.
If you can see any of these, it’s time to have the joints looked at:
- Gaps behind new kitchen upstands
- Leaking shower tray seals in a new home
- Sealant work across a run of new homes
- Joints pulling apart as timber shrinks
For new homes near Andover station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before booking
- How hidden problems are handled
- Are they insured?
- Whether the sealant suits the joint
- Whether all the old sealant comes out first
New build mastic around Chilbolton
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Around Chilbolton, as everywhere, new build mastic is only as good as the preparation behind it.
Chilbolton is about 4 miles south-east of Andover, in Hampshire. Whether you’re in the middle of Chilbolton or further out, new build mastic is available for homes and businesses alike, from flats and houses to offices and hotels. Chilbolton is one of 683 towns and villages in Hampshire we cover. We also work in Southampton, around 16 miles away.

Landmarks near Chilbolton

DIY versus a professional finish
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 fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
What happens if it’s left?
Resealing everything on a snagging list in one visit is normally simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times. Where a wall is exposed, as many are in small places like Chilbolton, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
