How we handle new build mastic in Stow Maries
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. We work on show homes, windows & doors and skirting & floors, and common reasons people get in touch are leaking shower tray seals in a new home and worktop and upstand sealant coming away.
Somewhere as small as Stow Maries, 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.
There’s a 12-month guarantee on every job, large or small.

DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
What the job involves on each surface
Plot handovers
Taking time over preparation reduces return visits. Dust from the build is removed first and prime where the product needs it.
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant that suits the frame.

What affects the quote in Stow Maries
Every job gets its own quote. These are the things that affect it:
- The size of the job
- Which sealant suits the joint
- How many areas need sealing
- The old material and how stubborn it is
We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- The rough size of the job
- Photos by email, if that’s easy
- The address or postcode of the job
- What’s wrong with the joints now
Getting a quote is simple: let us know what needs doing and where. A few pictures by email make the job easier to understand, and we will take it from there.
How it works
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours for most snagging lists, longer for a run of plots, depending on the size of the job. In a small place like Stow Maries, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Stow Maries: your questions answered
Do you cover smaller places like Stow Maries?
Yes. Stow Maries is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near North Fambridge station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
Who should fix failed sealant in a new build?
If you’re still within the builder’s snagging or warranty period, report it to them first. If it isn’t sorted, or keeps failing, get in touch with us.
Can I send you my snagging list?
Yes. Send the list and a few photos of the sealant items and we will give you a quote. We will tell you if anything on it isn’t a sealant job.
Can new sealant go on top of the old bead?
No. Fresh silicone does not stick to the old layer, so it soon lifts and traps water. The old sealant always comes out first.
How long does the job take?
A typical job takes a few hours in a single home. We’ll confirm how long when we quote.
Signs you need new build mastic in Stow Maries
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
Keep an eye out for these signs:
- Joints pulling apart as timber shrinks
- Untidy sealant flagged on a snagging list
- Cracked caulk along new skirting
- Worktop and upstand sealant coming away
For new homes near North Fambridge station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before you book
- Which colour the sealant will be
- Who turns up on the day
- Which sealant they’ll use, and why
- What guarantee comes with the work
