New-build mastic & snagging in Cop Street, Kent

Do you need new build mastic in Cop Street?
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Both fail early.
Common reasons people contact us are:
- Leaking shower tray seals in a new home
- Gaps behind new kitchen upstands
- Cracked sealant around new window and door frames
- Plot mastic for developers ahead of handover
For new homes near Sandwich station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before booking
- Is VAT in the price?
- What insurance they hold
- What happens if they find a problem under the old sealant
- What product goes in the joint
New build mastic in Cop Street, done properly
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly rather than sitting on a layer of grit. If you have skirting joints opening in the first winter and kitchen sealant that has pulled off the wall, we can put it right.
Older homes in small places like Cop Street often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Surface by surface
Show homes
Tired or marked sealant in a show home can be renewed. We cut it out and reseal neatly.
Plot handovers
Good preparation at handover saves snagging later. Dust from the build is removed first.
Why it’s worth doing now in Cop Street
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. Around Cop Street, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.
Why Cop Street customers choose us
- One-year guarantee on every job
- Experience in homes, commercial sites and hotels
- Any old sealant cut out fully, not covered over
- White, clear, grey or coloured to suit, where the product allows

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 tell us about it when you ask for a quote.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

We work for letting agents and landlords as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
If you manage several properties in or around Cop Street, several properties can be quoted together. Send us the addresses and the work at each, and pictures by email help.
How it works
You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes a few hours in a single home for a typical job. In a small place like Cop Street, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- Each area is checked and left with its cure time.
Before we arrive
- Mention if the joints have been sealed before
- Tell us if parking is tricky
- Mention any sign-in or site rules at work premises
Getting a quote
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we’ll take it from there.
