- New-build shower sealant that has already split
- Smeared, uneven beads picked up at snagging
How the visit works
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes anything from a few hours to several days, depending on the number of plots. Somewhere as small as Lower Upham, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- 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.
- Each area is checked and left with its cure time.
Preparing for the visit
- Keep children and pets away from the work area
- For indoor joints, keep the area dry beforehand if you can
- Tell us about access, such as stairs, a lift or high-level joints

New build mastic for homes and businesses in Lower Upham
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you are still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. We work on kitchens, skirting & floors and show homes, and the jobs we see most are untidy sealant flagged on a snagging list and beads laid onto grit and dust from the build.
Work in a small place like Lower Upham just needs the journey and access planning, and the work itself is the same as on any site.
You get a 12-month guarantee, the same in Lower Upham as everywhere else we work.

When something else is needed
Sealant is not the answer to every problem, and we will tell you before work begins. It will not solve:
- Broken tiles or a split tray
- Your warranty claim itself, which is between you and the builder
- A tray or bath that is not properly supported, until it’s fixed
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before booking.

How to look after the new joints
So the new joints stay in good condition:
- Photograph failed sealant before it’s redone
- Clean sealant with mild detergent, not abrasives
- Keep water off fresh sealant until it has cured
- Don’t wait for the house to settle if water is getting through
Don’t stand on the bath edge or the lip of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
How the job changes by surface
Plot handovers
Plot mastic is carried out to the developer’s schedule. Each joint is cleaned and primed where needed.
Kitchens
As a new house dries, worktops and walls shift a little, opening gaps behind the upstand. We reseal them with a flexible sealant.
Your questions about new build mastic in Lower Upham
Will you come out to Lower Upham?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you cover Lower Upham for new build mastic?
Yes, Lower Upham is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and we will quote it together.
When is the sealant fully cured?
It depends on the product and the temperature. We tell you how long to leave it before we go.
Do you work for letting agents?
Yes. Domestic, commercial and hotel work are all part of what we do.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.

The most common problems we see are:
- Second-fix sealing on new plots
- Beads laid onto grit and dust from the build

Leave it or put it right?
A quick bead over the top of the old sealant can look fine at first, but it will not bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. Older cottages and farmhouses around Lower Upham can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and give you a clear price before work begins.
