New build mastic in Baffins
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. If you are dealing with frame joints opening as the plaster dries and sealant that never bonded to the surface, we can put it right.
For a new home in or near Baffins, it’s worth checking the sealant early. Common snags include open skirting joints, lifting shower seals and gaps around frames.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Questions from Baffins
Is Baffins within the area you cover?
Yes. Baffins 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.
Do you work for landlords with property near Fratton station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses, and we’re fully insured.
Can new sealant go on top of the old bead?
No. We always remove the existing bead, the joint cleaned and primed where needed, before resealing.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Is it normal for sealant to crack in a new home?
Cracking in the first couple of years is common. Rushed application on dusty surfaces makes it worse.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Do you take on second-fix sealing for builders?
Yes. We seal plots to the developer’s programme ready for handover. Tell us the plots and the joints involved for a clear quote.
New build mastic in Baffins: local notes
Baffins is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Around Baffins, as everywhere, new build mastic is only as good as the preparation behind it. If you’ve bought a new home near Fratton station, the sealant around baths, showers and frames is worth checking in the first year or two.

How the job changes by surface
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.
Plot handovers
Developers can send the plot schedule and specification. We seal bathrooms, kitchens, frames and floors as agreed.
What happens if it’s left?
The builder is generally the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In a smaller place like Baffins, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and send you a clear quote before any work starts.

Landlord and commercial work in Baffins
Letting agents often deal with us directly. Tell us the address, the job and how access works.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
The process
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes a few hours in a single home, including the tidy-up. In a smaller place like Baffins, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We go through the snagging list or plot schedule and agree the joints to do.
- We cut out every bit of the failed or messy sealant.
- 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
- For indoor joints, keep the area dry beforehand if you can
- For business premises, tell us about site rules or sign-in
- Let us know about earlier repairs to the joints
Ask for a quote
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Clean sealant with mild detergent, not abrasives
- Keep photos and emails about snagging items
- Get a leaking seal dealt with straight away
- Use the extractor fan every time you shower
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers so moisture does not sit on the sealant.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you.
