Landlords, agents and businesses in Croftamie

We work for landlords and agents as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
About our new build mastic in Croftamie
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks instead of bonding to the dust. We work on bathrooms & en suites, skirting & floors and plot handovers, and the jobs we see most are plot mastic for developers ahead of handover and worktop and upstand sealant coming away.
For a place like Croftamie, the journey and access are planned in advance. Inside work goes ahead in any weather; outside mastic needs a dry day.
You get a one-year guarantee, the same in Croftamie as everywhere else we work.

What else we do in Croftamie
Why deal with it now?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it will not bond to the old layer. A lasting seal starts with removing the old one completely. In an older home around Croftamie, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.

Joints and finishes in Croftamie homes
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. Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.
In and around Croftamie, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Can I do it myself?
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.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Croftamie: your questions answered
Is new build mastic in Croftamie guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Do you cover smaller places like Croftamie?
Yes. Croftamie is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
What colour sealant will you use?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before we start.
Can you reseal over the builder’s sealant?
No. The old sealant is cut out fully, then clean and prime the joint, and a new bead applied.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few photos.
Do you have insurance?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
What affects the cost of new build mastic
Your quote is based on your job. We look at:

Different surfaces, different methods
Kitchens
As a new house dries, worktops and walls shift a little, opening gaps behind the upstand. We reseal them with a flexible sealant.
Plot handovers
Good preparation at handover saves snagging later. Dust from the build is removed first and primer used where needed.
How it works
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most snagging lists, longer for a run of plots. Outside jobs in Croftamie need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- 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.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Mention any parking rules near the property
- Clear the area around the work

What we’re called out for in Croftamie
Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints are not always given time to dry before the sealant goes on.
Most people get in touch when they notice something like this:
- Plot mastic for developers ahead of handover
- Gaps behind new kitchen upstands
- Gaps opening as the house dries out and settles
- New-build shower sealant that has already split
Whether the job is in Croftamie itself or nearby, the right material for each joint matters as much as a neat finish.
