About our new build mastic in Myrke
Snagging sealant properly means taking the failed bead out completely. Fresh silicone cannot bond to the old layer, so it all comes out before we clean, dry and reseal. If you have untidy sealant flagged on a snagging list and internal frame sealant that has split, we can put it right, whatever the surface.
Somewhere as small as Myrke, 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.
A one-year guarantee comes as standard.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Open a window or run the fan after bathing
- Keep photos and emails about snagging items
- Follow the cure time we give you
- Do not wait for the house to settle if water is getting through
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing so moisture does not sit on the sealant.
Early snagging is easier snagging. Left alone, a small crack can become a leak over time.
What affects the cost of new build mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- The old material and how stubborn it is
- Working hours on commercial sites
- How many rooms, windows or areas are involved
- Any mould that needs treating
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What to tell us for a quote
You do not need to know the technical terms. It helps if you can tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Pictures of the joints, sent by email
- Roughly how big the job is
- If it’s domestic, commercial or a hotel

Do you need new build mastic in Myrke?
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes do not always leave time for joints to dry before the sealant goes on.
These are the problems we’re asked about most:
- Gaps behind new kitchen upstands
- Skirting joints opening in the first winter
- New-build shower sealant that has already split
- Sealant applied over dusty or wet surfaces
In and around Myrke, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How much does new build mastic cost in Myrke?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
My new home is still under warranty. Should I contact you?
If you’re still within the builder’s snagging or warranty period, report it to them first. If it is not sorted, or keeps failing, get in touch with us.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Is it normal for sealant to crack in a new home?
It’s common, and there are usually two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What we do, step by step
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours in a single home. For a village or hamlet like Myrke, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we work through your snagging list or plot schedule with you.
- Failed or untidy sealant is cut out completely.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you are given the cure time.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit

What else we do in Myrke
How the job changes by surface
Skirting and floors
Wet-area floor joints need a flexible seal. We seal them with a sealant suited to wet areas.
Plot handovers
Good preparation at handover saves snagging later. Dust from the build is removed first and primer used where needed.
Leave it or put it right?
Small cosmetic gaps can wait for the house to settle, but water getting through can’t. If you are unsure which you have, call 0345 464 0079 or email us with photos and we’ll tell you. In a small place like Myrke, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.
