About our new build mastic in Moreton
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference, because that’s what rushed new-build sealant generally lacks. If you have joints pulling apart as timber shrinks and kitchen sealant that has pulled off the wall, we can put it right, on plot handovers, bathrooms & en suites and show homes alike.
For a small place like Moreton, the journey and access are planned in advance, and the work itself is the same as on any site.
All our work is covered by our one-year guarantee, wherever you are in Oxfordshire.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
How we quote for new build mastic
Every job gets its own quote. This is what makes a difference:
- Any mould that needs treating
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
- Access and height
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What we need to know
When you contact us, these details help:
- The address or postcode of the job
- Whether it’s a home or a business
- If someone has resealed it before
- How many joints, rooms or windows are involved
Want a quote for new build mastic? Please phone 0345 464 0079 or email us and tell us about the job. We’ll explain what we’d do and send you a clear quote before any work starts.
How it works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Moreton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- 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.
How to prepare
- Tell us about any water getting in
- Mention if the joints have been sealed before
- On commercial sites, let us know about site rules

Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit.
Do you take on second-fix sealing for builders?

Honest limits

- Structural cracks in walls or ceilings

Aftercare tips
To keep the joints looking good and working properly:
- Resist patching a failed seal with a tube from the DIY shop
- Check bath and shower seals every few months as the house settles
- Don’t wait for the house to settle if water is getting through
- Follow the cure time we give you
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day to cure enough for use.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small and the new finishes intact.
Do you need new build mastic in Moreton?
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and can tear.
Look out for any of the following:
- Cracked sealant around new window and door frames
- Kitchen sealant that has pulled off the wall
- Sealant work across a run of new homes
- Messy sealant that spoils new finishes
In and around Moreton, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Why act early in Moreton
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. In a small place like Moreton, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first.
Why Moreton customers choose us
- Anti-fungal sanitary silicone in wet areas
- Homes, businesses and hotels
- Any old sealant cut out fully, not covered over
- Quality sealants from Arbo and Everbuild
