Brize Norton New Build Mastic
We cover Brize Norton for plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- Gaps between new skirting and floors
- Second-fix sealing on new plots
- Cracked sealant around new window and door frames
How we handle new build mastic in Brize Norton
We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. We work on skirting & floors, show homes and kitchens, and the jobs we see most are smeared, uneven beads picked up at snagging and new-build shower sealant that has already split.
Somewhere as small as Brize Norton, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
All our work comes with our one-year guarantee, wherever you are in Oxfordshire.

Quotes for new build mastic in Brize Norton
Your quote is based on your job. We look at:
- Any mould that needs treating
- The product the joint needs
- Whether the work is at height

What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:

- Access, such as stairs, a lift or height
- Any previous sealing or DIY work
- How many joints, rooms or windows are involved
Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we will talk you through the work before giving you a price.
Surface by surface
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in and baths are filled before sealing.
Show homes
In a show home, the sealant is on display. Every bead is neat and coloured to suit the room.
Common problems we fix in Brize Norton
Sealant applied onto damp surfaces doesn’t bond well. Site programmes don’t always leave time for joints to dry before the sealant goes on.
People generally contact us when they notice one of these:
- New-build shower sealant that has already split
- Sealant work across a run of new homes
- Cracked sealant around new window and door frames
- Skirting joints opening in the first winter
For jobs in and around Brize Norton, choosing the right material for each joint is as important as a tidy finish.

Common questions in Brize Norton
Do you cover Brize Norton for new build mastic?
Yes. Our work covers London and the South East, and Brize Norton is part of that. You can call 0345 464 0079 or send us an email and let us know what needs doing.
Is Brize Norton within the area you cover?
Yes, Brize Norton is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What do you need from me for a quote?
A short description and the location. If we need more, we will ask.
Is there a guarantee?
Yes. There’s a 12-month guarantee on every job.
Can new sealant go on top of the old bead?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.
Are you fully insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Should I go to my builder first?
If you’re still within the builder’s snagging or warranty period, report it to them first. If they’re slow or the fix does not last, we can help.
Why does sealant fail so quickly in new builds?
New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.
What happens on the day
We keep the work tidy and contained to the area we are working on, so you can get on with your day. The job generally takes a few hours in a single home. In a small place like Brize Norton, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- Tell us about any water getting in
- Clear the area around the work
- Tell us about any previous sealing or DIY attempts

What else we do in Brize Norton
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Open a window or run the fan after bathing
- Avoid running a DIY bead over the old one
- Keep pictures and emails about snagging items
- Get a leaking seal dealt with straight away
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant.

Why deal with it now?
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. Around Brize Norton, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit is generally more efficient than separate visits. We will send you a clear quote for the lot.
Why us?
- We never seal over old sealant
- Anti-fungal silicone where joints get wet
- Homes, businesses and hotels
- White, clear, grey or coloured to suit, where the product allows
