About our new build mastic in Killearn
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. We work on bathrooms & en suites, kitchens and show homes, and common reasons people get in touch are worktop and upstand sealant coming away and cracked caulk along new skirting.
Many newer homes in Scotland are timber-framed and settle as they dry out, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
You get a 12-month guarantee, the same in Killearn as everywhere else we work.

Your questions about new build mastic in Killearn
What guarantee comes with new build mastic in Killearn?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Is Killearn within the area you cover?
Yes. Killearn is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
How much does new build mastic cost in Killearn?
It depends on the job, so we quote each one individually. For a quick quote, drop us a line at info@mrmastic.co.uk with a short description of the job.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses and we’re fully insured.
Should I go to my builder first?
If you’re still within the builder’s snagging or warranty period, report it to them first. If it isn’t sorted, or keeps failing, get in touch with us.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access.
Is it worth resealing while the house is still settling?
It depends on whether water is getting through. A leaking shower or bath seal should be redone right away, but cosmetic gaps can wait for movement to slow.
Are you fully insured?
Yes, we’re fully insured.
How we quote for new build mastic
Your quote is based on your job. We look at:
- How many areas need sealing
- How easy the joints are to reach
- When we can work, for business premises
- Whether old sealant or filler has to be cut out
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- Access, such as stairs, a lift or height
- The rough size of the job
- If someone has resealed it before
- What the problem is, such as mould, gaps, leaks or cracking
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.
How it works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on the number of plots. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Before we arrive
- Mention any tricky access
- Mention any parking rules near the property
- Clear items away from the joints we’re working on

Some problems need a builder, plumber or other trade rather than us:
- Settlement cracks that need a surveyor
- Disputes or warranty claims with your builder
- Plumbing faults behind the sealant
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly before you book.

When to call us in Killearn
Sealant applied onto damp surfaces does not bond well. On a busy site, joints are not always given time to dry first.
Most people get in touch when they notice one of these:
- Internal frame sealant that has split
- Beads laid onto grit and dust from the build
- Shower seals failing in the first year or two
- Smeared, uneven beads picked up at snagging
Whether the job is in Killearn itself or nearby, the right material for each joint matters as much as a neat finish.

New build mastic around Killearn
The west of Scotland is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
In and around Killearn, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Surface by surface
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish. Tell us when the home is open so we can plan around it.
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.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
