How we handle new build mastic in Sandling
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. Both get the same care over preparation since hurried prep is behind a lot of new-build failures. We work on kitchens, windows & doors and plot handovers, and the jobs we see most are smeared, uneven beads picked up at snagging and gaps behind new kitchen upstands.
Around Sandling, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
We stand behind the work with a one-year guarantee, so you’re covered after we have gone.

Why deal with it now?
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. Around Sandling, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Resist patching a failed seal with a tube from the DIY shop
- Do not wait for the house to settle if water is getting through
- Follow the cure time we give you
- Wipe joints with warm soapy water
Follow the cure time we give you before the area gets wet. Silicone is usually left for about a day before water reaches them.
Early snagging is easier snagging. Small faults turn into leaks if left in a busy bathroom.
The process
The work is kept neat and contained to the area we’re working on, so you can get on with your day. The job generally takes a few hours in a single home. For a village or hamlet like Sandling, 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.
- Each joint is checked for movement before we start.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Preparing for the visit
- Mention any tricky access
- Tell us about any water getting in
- For business premises, tell us about site rules or sign-in

Advice
When it is not the sealant

Joints and finishes in Sandling homes

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Sandling: your questions answered
Do you cover smaller places like Sandling?
Yes. Sandling is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Maidstone East station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Can you reseal over the builder’s sealant?
No. New silicone won’t bond to old silicone, so sealing over the top fails quickly. We cut the old bead out completely.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you when we finish.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Who should fix failed sealant in a new build?
Your builder, if you are still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it and our work is guaranteed for a year.
Can you match the sealant colour to my new kitchen or bathroom?
It depends on the joint: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before we start.
