About our new build mastic in Durlock
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a seal that’s letting water through needs doing now. We work on windows & doors, skirting & floors and kitchens, and the jobs we see most are leaking shower tray seals in a new home and second-fix sealing on new plots.
Work in a small place like Durlock just needs the journey and access planning, and once on site, the job is the same as anywhere.
Our work is backed for twelve months.

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Get a leaking seal dealt with straight away
- Use the extractor fan every time you shower
- Check bath and shower seals every few months as the house settles
- Wait for the cure time before using a resealed shower
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant.
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.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
For landlords and businesses
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
We also work for property managers and facilities teams in Durlock and across Kent. We can quote a run of properties together, and we are fully insured.
What affects the quote in Durlock
The quote reflects the job in front of us. We take into account:
- Which sealant suits the joint
- The size of the job
- Any mould that needs treating
- Working hours on commercial sites
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- What’s wrong with the joints now
- Access, such as stairs, a lift or height
- Photos by email, if that’s easy
- The type of property
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
What the job involves on each surface
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out and baths are filled before sealing.
Kitchens
New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.
How it works
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Durlock, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you’re given the cure time.
Getting ready for the visit
- Mention if the joints have been sealed before
- Mention any tricky access
- Clear items away from the joints we’re working on

What we are called out for in Durlock
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. As it does, timber shrinks and joints open, and sealant that can’t keep up splits.
If you can see any of these, it’s time to have the joints looked at:
- Joints pulling apart as timber shrinks
- Sealant work across a run of new homes
- Internal frame sealant that has split
- Messy sealant that spoils new finishes
For new homes near Sandwich station, it’s worth checking the sealant early, while snags are still fresh.
Before you book anyone
- Whether they seal over old material or remove it
- When the joint can take water or movement
- Is VAT in the price?
