New build mastic for homes and businesses in Mundy Bois
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. If you’re dealing with gaps opening as the house dries out and settles and gaps behind new kitchen upstands, we can help.
Around Mundy Bois, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Big or small, you get the same 12-month guarantee.

Quotes for new build mastic in Mundy Bois
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How many areas need sealing
- When we can work, for business premises
- Whether old sealant or filler has to be cut out
- Whether the work is at height
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price 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:
- Access, such as stairs, a lift or height
- Pictures of the joints, sent by email
- If someone has resealed it before
- The rough size of the job
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
When it isn’t the sealant
To be straight with you, there are a few things sealant won’t fix:
- Cracked trays, tiles or worktops
- Movement caused by a poorly fitted tray or bath
- Leaks from pipes, valves or wastes, which need a plumber
If you are not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer before booking.

Your questions about new build mastic in Mundy Bois
Do you cover smaller places like Mundy Bois?

Can you help a landlord with a rental near Pluckley station?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.
Can I send you my snagging list?
Yes. Send it with pictures and we’ll quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
Do you have insurance?
Yes. We’re fully insured.
Is the work guaranteed?
Yes, always. Each job is guaranteed for twelve months.
Why has my new-build shower seal failed already?
New homes dry out and move in their first couple of years, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Do you need new build mastic in Mundy Bois?
On many sites, sealant goes on in the final rush before handover. Joints aren’t always cleaned of dust or primed, so the bead never bonds properly.
These are the problems we’re asked about most:
- Untidy sealant flagged on a snagging list
- Frame joints opening as the plaster dries
- Joints pulling apart as timber shrinks
- Worktop and upstand sealant coming away
In and around Mundy Bois, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
