New build mastic in Stonehills
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you’re still within the builder’s snagging or warranty period, tell them first. Common call-outs are for cracked caulk along new skirting and shower seals failing in the first year or two, across kitchens, windows & doors and bathrooms & en suites.
In a village or hamlet like Stonehills, 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.
Our work is backed for twelve months.

Questions from Stonehills
Can you do new build mastic in Stonehills?
Yes. Our work covers London and the South East, and Stonehills is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing.
Do you cover smaller places like Stonehills?
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.
How much does new build mastic cost in Stonehills?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
Will you just run a new bead over the existing one?
No. The old sealant is cut out fully, the joint cleaned and primed where needed, before resealing.
Should I go to my builder first?
While the snagging or warranty period runs, the builder should be your first contact. If they’re slow or the fix does not last, we can help.
Can landlords and businesses book you?
Yes, regularly. We can quote for several properties at once, and between tenancies is a good time for the work.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Do you work for developers?
Yes. We seal plots to the developer’s programme ready for handover. Get in touch with the number of plots and the scope for a clear quote.
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Photograph failed sealant before it’s redone
- Raise failed sealant with the developer while you are covered
- Use the extractor fan every time you shower
- Wait for the cure time before using a resealed shower
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing to help keep mould away.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left.
For landlords and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll quote.
We also work for property managers and facilities teams. Several sites can be quoted together, and we are fully insured.
Different surfaces, different methods
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one.
Plot handovers
Developers can send the plot schedule and specification for a quote. We seal bathrooms, kitchens, frames and floors.
Signs you need new build mastic in Stonehills
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
These are the problems we are asked about most:
- Untidy sealant flagged on a snagging list
- Frame joints opening as the plaster dries
- Beads laid onto grit and dust from the build
- Cracked caulk along new skirting
For new homes near Hamble station, it’s worth checking the sealant early, while snags are still fresh.
What to look for in a quote
- Whether you can choose the colour
- Whether VAT is included
- What preparation is included
- What insurance they hold
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for most snagging lists, longer for a run of plots and we leave things clean and tidy. In a small place like Stonehills, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Getting ready for the visit
- Clear the area around the work
- Tell us about any previous sealing or DIY attempts
- Mention any parking rules near the property

Advice
How we quote for new build mastic
The price is agreed before any work begins. It’s based on:
- Whether the work is at height
- How much there is to do
- How many rooms, windows or areas are involved
- The old material and how stubborn it is
What you pay reflects the work, not guesswork. That is why we ask about the job first.
What we need to know
You don’t need to know the technical terms. It helps if you can tell us:
- Photos by email, if that is easy
- If it’s domestic, commercial or a hotel
- Any previous sealing or DIY work
- Roughly how big the job is
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.
Joints and finishes in Stonehills homes
Stonehills is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
