About our new build mastic in Newbury
We never seal over a failed new-build bead. Fresh silicone cannot bond to the old layer, so the joint is cut out, cleaned, dried and resealed. We work on windows & doors, plot handovers and kitchens, and common reasons people get in touch are beads laid onto grit and dust from the build and gaps opening as the house dries out and settles.
Towns like Newbury have older streets and newer estates side by side. In a newer home, sealant and floor joints are generally among the first things to need attention.
You’re covered for a year from the day we finish. If anything is not right with it, phone 0345 464 0079 or drop us an email.

Newbury: your questions answered
Can you help a landlord with a rental near Newbury station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Is new build mastic in Newbury guaranteed?
All our work, in Newbury and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or email us.
Should I wait before resealing?
That depends on the joint. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
Can I send you my snagging list?
Yes. Send the list and a few photos of the sealant items and we’ll give you a quote. We will tell you if anything on it is not a sealant job.
Who should fix failed sealant in a new build?
Start with the builder if you are in the snagging or warranty period. Once that’s done, or if they won’t put it right, we can reseal it properly.
Do you work for developers?
Yes. We work through plots to your schedule, room by room. Get in touch with the number of plots and the scope for a clear quote.
Other services in Newbury
Leave it or put it right?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. Around Newbury, failed sealant lets water into hidden places, like the floor under a bath, the back of a panel or the inside of a wall. Whatever the joint, failed sealant only gets worse.
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.

What happens on the day
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours in a single home. For a job in Newbury, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
How to prepare
- On commercial sites, let us know about site rules
- Clear items away from the joints we are working on
- Keep children and pets away from the work area

Related advice
What we are called out for in Newbury
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly and it shows once the home is in use.
Common reasons people contact us are:
- Shower seals failing in the first year or two
- Skirting joints opening in the first winter
- Beads laid onto grit and dust from the build
- Gaps opening as the house dries out and settles
For new homes near Newbury station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before you book
- The length of the guarantee
- How the colour is chosen
- What the quote includes, VAT included or not
- Are they insured?
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Record problems with dated photos
- Use the extractor fan every time you shower
- Keep water off fresh sealant until it has cured
- Do not seal over failed sealant yourself
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it as they wear the bead.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant.
How we quote for new build mastic
Jobs vary more than people expect. What affects the quote:
- Whether the work is at height
- How much there is to do
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.
What we need to know
Before you ask for a quote, have a think about:
- Where the job is, and your postcode
- Roughly how big the job is
- Photos by email, if that is easy
- The problem you’ve noticed
We quote each job on its own, so start by telling us what you need. Just call 0345 464 0079 or drop us an email with the details.
