New-build mastic & snagging in Coombe, Kent
New-build sealant joints in Coombe need attention? We cut out the old, prepare the joints and apply the right sealant.
- Worktop and upstand sealant coming away
- Cracked caulk along new skirting
- Sealant applied over dusty or wet surfaces
DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
New build mastic in Coombe
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you’re still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. We are often asked to deal with gaps behind new kitchen upstands and smeared, uneven beads picked up at snagging, across plot handovers, windows & doors and kitchens.
For a small place like Coombe, the journey and access are planned in advance, and the work itself is the same as on any site.
Big or small, it’s backed by our 12-month guarantee in Coombe and across Kent.

How to look after the new joints
After the cure time, these simple habits help:
- Avoid running a DIY bead over the old one
- Act quickly if a seal starts to leak
- Clean sealant with mild detergent, not abrasives
- Look at the sealant regularly in the first couple of years
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it, which can damage the surface.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small.
What affects the cost of new build mastic
You’ll get a clear quote before work begins. It’s based on:
- How much there is to do
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.
What we need to know
Photos help, but a description is a good start. Try to tell us:
- The address or postcode of the job
- Photos by email, if that is easy
- The rough size of the job
- What the problem is, such as mould, gaps, leaks or cracking
We quote each job on its own, so start by telling us what you need. Simply ring 0345 464 0079 or send us an email and describe the job, and photos are welcome.
When it is not the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Leaks from pipes, valves or wastes, which need a plumber
- Disputes or warranty claims with your builder
- A tray or bath that is not properly supported, until it’s fixed
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think before booking.

What we are called out for in Coombe
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly and cracks appear in the sealant.
The most common problems we see are:
- Kitchen sealant that has pulled off the wall
- New-build shower sealant that has already split
- Sealant that never bonded to the surface
- Cracks appearing as a new home settles
For new homes near Sandwich station, it’s worth checking the sealant early, while snags are still fresh.

Why it’s worth doing now in Coombe
Small cosmetic gaps can wait for the house to settle, but a leaking seal can’t. Not sure whether yours can wait? You can ring 0345 464 0079 or drop us an email with a few photos and we will give you a straight answer. Older cottages and farmhouses around Coombe can have timber 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.
