New build mastic in Old Tree
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first. Common call-outs are for gaps opening as the house dries out and settles and sealant that never bonded to the surface, across windows & doors, skirting & floors and plot handovers.
Work in a small place like Old Tree just needs the journey and access planning, and the work itself is the same as on any site.
Big or small, you get the same 12-month guarantee in Old Tree and across Kent.

What we do, step by step
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Old Tree, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we’re working on

Landlord and commercial work in Old Tree
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can go on one quote.
For anyone letting property in or around Old Tree, several properties can go on one quote. Just tell us the addresses and what each one needs.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
How we quote for new build mastic
Every job gets its own quote. These are the things that affect it:
- The size of the job
- Any working-time requirements on site
- The product the joint needs
- Whether the work is at height
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.
What we need to know
You don’t need to know the technical terms. Just tell us:
- Whether it has been sealed before
- How we’d reach the joints
- Whether it’s a home or a business
- What the problem is, such as mould, gaps, leaks or cracking
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. When it suits you, call 0345 464 0079 or email us.

How long will you be here?
As a guide, most jobs take a few hours for most snagging lists, longer for a run of plots. Bigger jobs take longer.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
Who should fix failed sealant in a new build?
While the snagging or warranty period runs, the builder should be your first contact. If it isn’t sorted, or keeps failing, get in touch with us.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and you’ll get one quote.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used.
Aftercare tips
After the cure time, these simple habits help:
- Follow the cure time we give you
- Ventilate bathrooms well, especially in the first year
- Wipe joints with warm soapy water
- Put sealant faults on your snagging list early
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you, so raise it early.
What the job involves on each surface
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Show homes
We can refresh show-home sealant that has discoloured or been knocked. We cut it out and reseal neatly.
New homes and floors in Old Tree
Old Tree is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For new homes near Herne Bay station, it’s worth checking the sealant early, while snags are still fresh.

- New-build shower sealant that has already split
- Cracks appearing as a new home settles
- Skirting joints opening in the first winter
- Messy sealant that spoils new finishes
Around Old Tree, as everywhere, new build mastic is only as good as the preparation behind it.
