Aftercare tips
To keep the joints looking good and working properly:
- Keep water off fresh sealant until it has cured
- Ventilate bathrooms well, especially in the first year
- Get a leaking seal dealt with straight away
- Watch for new gaps as the house dries out
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers so moisture doesn’t sit on the sealant.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
Quotes for new build mastic in Biddenden
Every job gets its own quote. This is what makes a difference:
- How much old sealant there is and how hard it is to remove
- Working hours on commercial sites
- Whether there’s mould to deal with
- The type of sealant required
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

Why deal with it now?
Resealing everything on a snagging list in one visit is normally simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times. Older cottages and farmhouses around Biddenden can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or email us and we’ll give you an honest view and a quote.

Biddenden: your questions answered
Is Biddenden within the area you cover?
Yes. Biddenden is within the area we cover, which takes in towns, villages and rural addresses. We work across 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 Headcorn station?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Why has my new-build shower seal failed already?
There are usually two causes: the house moving as it dries, and sealant that never bonded properly. A proper reseal deals with both.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access.
Do you guarantee your work?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
When it is not the sealant
To be straight with you, some problems need a different trade:
- Leaking fittings rather than failed sealant
- Movement caused by a poorly fitted tray or bath
- Your warranty claim itself, which is between you and the builder
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly.

What happens on the day
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Biddenden, 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 going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- On commercial sites, let us know about site rules
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive

Work for landlords, hotels and businesses
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Hotels need rooms back in use, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
Common problems we fix in Biddenden
Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and the sealant may split.
Most people get in touch when they notice something like this:
- Beads laid onto grit and dust from the build
- Frame joints opening as the plaster dries
- Gaps between new skirting and floors
- Kitchen sealant that has pulled off the wall
In and around Biddenden, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
