New build mastic in Micklefield Green, done properly
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first, and if it is not put right, get in touch with us. We work on bathrooms & en suites, skirting & floors and windows & doors, and the jobs we see most are gaps between new skirting and floors and worktop and upstand sealant coming away.
In a village or hamlet like Micklefield Green, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

How the job changes by surface
Windows and doors
A draught at a new window can be a missed or failed joint. We check and reseal the frame edges.
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. A proper reseal keeps water in the tray.
What we do, step by step
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours for most snagging lists, longer for a run of plots. For a village or hamlet like Micklefield Green, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Before we arrive
- Tell us if parking is tricky
- Keep pets and children clear of the area while we work
- Mention any leaks or damp you’ve noticed

Micklefield Green: your questions answered
Do you cover Micklefield Green for new build mastic?
Yes, Micklefield Green is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing.
Is Micklefield Green within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can I send you my snagging list?
Yes. Send the list and a few photos of the sealant items, and we’ll quote. We will tell you if anything on it is not a sealant job.
What colour sealant will you use?
It depends on the joint: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before any work starts.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
What do you need from me for a quote?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or drop us an email.
Can new sealant go on top of the old bead?
No. New silicone will not bond to old silicone, so sealing over the top fails quickly. We cut the old bead out completely.
How we quote for new build mastic
Call for a quick quote. The main things that affect it are:
- Access and height
- How much old sealant there is and how hard it is to remove
- The product the joint needs
- Any mould that needs treating
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What to tell us for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Any access issues, like height or stairs
- Pictures of the joints, sent by email
- If someone has resealed it before
- The type of property
We quote each job on its own. Simply call 0345 464 0079 or send us an email and describe the job.
Looking after it afterwards
Aftercare is simple:
- Clean sealant with mild detergent, not abrasives
- Keep pictures and emails about snagging items
- Avoid running a DIY bead over the old one
- Check bath and shower seals every few months as the house settles
Keep pictures of the joints and any snagging correspondence with your builder. 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. Early resealing keeps the job small and protects the rest of the house.
What we’re called out for in Micklefield Green
On many sites, sealant goes on in the final rush before handover. Joints aren’t always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
People normally contact us after spotting something like this:
- Plot mastic for developers ahead of handover
- Leaking shower tray seals in a new home
- Skirting joints opening in the first winter
- Internal frame sealant that has split
Around Micklefield Green, as everywhere, new build mastic is only as good as the preparation behind it.

When it is not the sealant
Sealant is not the answer to every problem, and we will tell you before work begins. It won’t solve:
- Disputes or warranty claims with your builder
- A tray or bath that is not properly supported, until it’s fixed
- Leaking fittings rather than failed sealant
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before you book.

What else we do in Micklefield Green
Why it’s worth doing now in Micklefield Green
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Older cottages and farmhouses around Micklefield Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email and we will give you an honest view and a quote.
