New build mastic in Overton, done properly
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover with a sealant suited to each area. Typical jobs include sealant work across a run of new homes and leaking shower tray seals in a new home, across show homes, kitchens and windows & doors.
Homes around Overton range from older cottages to newer houses, and their floors range just as widely, from timber that moves with the seasons to tiles laid on concrete. The sealant at skirtings and thresholds has to suit the floor it meets.
You get a one-year guarantee, the same in Overton as everywhere else we work.

What the job involves on each surface
Windows and doors
On new builds, external frame sealant can be patchy. We reseal it with a weatherproof, flexible sealant.
Show homes
We seal show-home bathrooms, kitchens and frames to a tidy standard. Tell us when the home is open so we can plan around it.

Overton: your questions answered
Do you cover smaller places like Overton?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Overton station. Can you help?
Yes, we work for landlords and agents. Just call 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or drop us an email.
How long should I leave it?
Cure times vary by product. Before we leave, we will tell you the cure time.
My new home is still under warranty. Should I contact you?
While the snagging or warranty period runs, the builder should be your first contact. If they’re slow or the fix doesn’t last, we can help.
What colour sealant will you use?
That depends on what the joint meets: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before work begins.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.

What we’re called out for in Overton
Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and can tear.
Keep an eye out for any of the following:
- Second-fix sealing on new plots
- Sealant that never bonded to the surface
- Untidy sealant flagged on a snagging list
- Shower seals failing in the first year or two
Around Overton, as everywhere, new build mastic is only as good as the preparation behind it.
What your quote should include
- How the surfaces are prepared before sealing
- Who turns up on the day
- Which sealant they’ll use, and why
- How long to leave it before use
What sealant work can’t fix
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Movement caused by a poorly fitted tray or bath
- Damaged fittings that need replacing
- Your warranty claim itself, which is between you and the builder
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.
What we seal
- Show homes
- Kitchens
- Skirting & floors
- Windows & doors
- Bathrooms & en suites
- Plot handovers
Leave it or put it right?
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times for the lot. In an older home around Overton, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will explain what it covers.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
How the visit works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for most snagging lists, longer for a run of plots. Parking around Overton is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Keep children and pets away from the work area
- Tell us about any previous sealing or DIY attempts
