New build mastic in Stenton, done properly
Snagging sealant properly means taking the failed bead out completely. Fresh silicone can’t bond to the old layer, so the joint is cut out, cleaned, dried and resealed. We work on plot handovers, kitchens and windows & doors, and common reasons people get in touch are cracks appearing as a new home settles and shower seals failing in the first year or two.
Around smaller Scottish places like Stenton, new homes tend to be single plots or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
You get a one-year guarantee, the same in Stenton as everywhere else we work.

How the visit works
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and tidy away. Most jobs take a few hours in a single home. Somewhere like Stenton may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We go through the snagging list or plot schedule and agree the joints to do.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Tell us if parking is tricky
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before

Leave it or put it right?
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

Should I try it myself first?
If you do try it yourself, take your time over the 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.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
How the job changes by surface
Windows and doors
Draughts around new frames are often a sealant gap. We check and reseal the frame edges.
Skirting and floors
Wet-area floor joints need a flexible seal. We seal them with a sealant suited to wet areas.
What affects the cost of new build mastic
Jobs vary more than people expect. The main factors:
- The number of rooms or windows
- Which sealant suits the joint
- Mould in or behind the old joints
- The size of the job
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and give you a clear price before work begins.
Asking for a quote
You do not need to know the technical terms. It helps if you can tell us:
- If someone has resealed it before
- The rough size of the job
- A few pictures by email, if you can
- Whether it’s a home or a business
We quote each job on its own, so the first step is telling us about yours. Simply email us at info@mrmastic.co.uk and describe the job and send pictures if you have them.
When it is not the sealant
To be straight with you, there are a few things sealant will not fix:
- Movement caused by a poorly fitted tray or bath
- Broken tiles or a split tray
- Cracking that points to a structural problem
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer before you book.
Surfaces we seal
- Windows & doors
- Kitchens
- Skirting & floors
- Bathrooms & en suites
- Plot handovers

Do you need new build mastic in Stenton?
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and can tear.
People generally contact us after spotting something like this:
- Sealant that never bonded to the surface
- Gaps opening as the house dries out and settles
- Shower seals failing in the first year or two
- Kitchen sealant that has pulled off the wall
If you’ve bought a new home near East Linton station, the sealant around baths, showers and frames is worth checking in the first year or two.

New build mastic in Stenton: local notes

In and around Stenton, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
