- Leaking shower tray seals in a new home
- Frame joints opening as the plaster dries
How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Look at the sealant regularly in the first couple of years
- Resist patching a failed seal with a tube from the DIY shop
- Keep photos and emails about snagging items
- Put sealant faults on your snagging list early
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents as they wear the bead.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left.
New build mastic for homes and businesses in Hardgate
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. We work on skirting & floors, show homes and bathrooms & en suites, and people most often call us about sealant applied over dusty or wet surfaces and new-build shower sealant that has already split.
Around smaller Scottish places like Hardgate, new homes tend to be single plots or small developments. They need their sealant and floor joints finished just as carefully as on a big site.
You get a one-year guarantee, the same in Hardgate as everywhere else we work.

The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.

- Sealant work across a run of new homes
- New-build shower sealant that has already split
- Frame joints opening as the plaster dries
- Gaps opening as the house dries out and settles

What the job involves on each surface
Windows and doors
Draughts around new frames are often a sealant gap. We check and reseal the frame edges.
Plot handovers
Developers can send the plot schedule and specification for a quote. We seal bathrooms, kitchens, frames and floors as agreed.
How the visit works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for most snagging lists, longer for a run of plots. For a place like Hardgate, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Keep pets and children clear of the area while we work
- Mention any sign-in or site rules at work premises

What affects the quote in Hardgate
Your quote is based on your job. We take into account:
- How much there is to do
- Whether the work is at height
- The old material and how stubborn it is
- The type of sealant required
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, drop us a line at info@mrmastic.co.uk and we will give you an honest view and a quote.

Common questions in Hardgate
Is Hardgate in your area for new build mastic?
Yes, Hardgate is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and let us know what needs doing.
I let a flat near Singer station. Can you help?
Yes, landlords and agents are among the people we work for. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
Is it worth resealing while the house is still settling?
Any seal that’s leaking should be redone right away. Cosmetic gaps can wait until the first year or two of movement has passed.
When is the sealant fully cured?
It depends on the product and the conditions. We tell you how long to leave it before we go.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us and we’re fully insured.
Can you reseal over the builder’s sealant?
No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.
Is it normal for sealant to crack in a new home?
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.
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
