Leave it or put it right?
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or isn’t dealt with, we can reseal it properly. Around Coalhill, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Why Coalhill clients choose us
- 12-month guarantee on every job

New build mastic for homes and businesses in Coalhill
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that’s reasonable, but a failed shower or bath seal shouldn’t wait. We work on skirting & floors, windows & doors and kitchens, and the jobs we see most are smeared, uneven beads picked up at snagging and shower seals failing in the first year or two.
Somewhere as small as Coalhill, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
Each job carries a 12-month guarantee, whatever its size.

What else we do in Coalhill
How the visit works
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the work takes a few hours for most snagging lists, longer for a run of plots in most cases. For a village or hamlet like Coalhill, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- Let us know about parking restrictions
- Mention any tricky access
- Mention any leaks or damp you’ve noticed

What affects the quote in Coalhill
There’s no set price list, because no two jobs are the same. What we look at:
- Whether the work is at height
- The old material and how stubborn it is
- How many rooms, windows or areas are involved
- Any mould that needs treating
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
Helping us quote
To make quoting easier, let us know:
- Whether it has been sealed before
- If it’s domestic, commercial or a hotel
- Any access issues, like height or stairs
- Where the job is, and your postcode

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, then guaranteed for a year.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- Broken tiles or a split tray
- Baths and trays that move too much for sealant to cope with
- Disputes or warranty claims with your builder
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.
What we seal
- Bathrooms & en suites
- Show homes
- Kitchens
- Skirting & floors
- Plot handovers
- Windows & doors
