How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours in a single home and we leave things clean and tidy. Somewhere like Fosten Green needs a little journey planning: 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.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
How to prepare
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height
- Let us know about parking restrictions

Signs you need new build mastic in Fosten Green
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes don’t always leave time for joints to dry first.
These are the problems we are asked about most:
- Cracked caulk along new skirting
- Cracked sealant around new window and door frames
- Sealant work across a run of new homes
- Gaps behind new kitchen upstands
For new homes near Headcorn station, it’s worth checking the sealant early, while snags are still fresh.

DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Use the extractor fan every time you shower
- Wait for the cure time before using a resealed shower
- Clean sealant with mild detergent, not abrasives
- Put sealant faults on your snagging list early
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day before water reaches them.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak in a busy bathroom.
Why act early in Fosten Green
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times for the lot. Around Fosten Green, older homes often have timber in their 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 not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.

For landlords and businesses
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
What the job involves on each surface
Kitchens
New-kitchen sealant is often applied in a rush. We remove it and reseal with a kitchen-suitable sealant.
Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk in a colour to suit.
