Joints and finishes in Janetstown homes

Janetstown is within about 3 miles of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.

Around Janetstown, as everywhere, new build mastic is only as good as the preparation behind it.

About our new build mastic in Janetstown

We work in new homes and on new-build sites across Janetstown. Whether it’s one en suite or a run of plots, the method is the same: remove, clean, prime where needed, then a neat new bead. Common call-outs are for frame joints opening as the plaster dries and gaps opening as the house dries out and settles, across kitchens, bathrooms & en suites and plot handovers.

Around smaller Scottish places like Janetstown, 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.

We stand behind the work with a 12-month guarantee.

Keeping the joints in good condition

Looking after new joints is easy, and it makes a real difference:

  • Keep photos and emails about snagging items
  • Raise failed sealant with the developer while you’re covered
  • Keep water off fresh sealant until it has cured
  • Avoid running a DIY bead over the old one

Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.

The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left.

What the job involves on each surface

Skirting and floors

As timber and screed dry, skirting and floors shift. Caulk cracks; a flexible sealant moves with it.

Kitchens

Beside the sink, the joint takes water every day. A kitchen sealant goes in there.

What happens if it’s left?

It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times. Around Janetstown, water from a failed joint in an older stone home can soak into timber and plaster.

What it costs depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start.

Why us?

  • ARBOMaster approved applicator
  • A choice of colours where the product allows
  • We leave the area clean and tidy
  • Colour agreed with you before any work starts

FAQs for Janetstown

Will you come out to Janetstown?

Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.

Do you work for landlords with property near Thurso station?

Yes, rental work is part of what we do. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before work begins.

Can I do it myself?

Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.

Do I have to be there?

Access is agreed with you when the job is booked. For inside work, that normally means someone being in.

Do you guarantee your work?

Yes. Each job is guaranteed for twelve months, large or small.

Can you work from my snagging list?

Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before work begins.

Are you an approved applicator?

Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.

Can you match the sealant colour to my new kitchen or bathroom?

That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We will agree it with you first.

Honest limits

We will always be straight with you, so here’s what new sealant won’t do:

  • Deciding who is responsible under a builder’s warranty
  • Cracking that points to a structural problem
  • Broken tiles or a split tray

If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer.

What we seal

  • Show homes
  • Bathrooms & en suites
  • Plot handovers
  • Skirting & floors
  • Windows & doors
  • Kitchens

DIY sealant or a professional job?

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.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

The process

When we get to you, we check the joints match what you told us. 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. Around Janetstown, distance and access matter more than parking. Tell us how to find the property and how to reach the work.

  1. First we work through your snagging list or plot schedule with you.
  2. We cut out every bit of the failed or messy sealant.
  3. We clean off dust from the build and prime the surfaces where the product needs it.
  4. We apply a sealant that suits each joint and tool it to a neat finish.
  5. We check every joint and tell you how long each needs to cure.

Getting ready for the visit

  • Tell us about access, such as stairs, a lift or high-level joints
  • Mention if the joints have been sealed before
  • Tell us if parking is tricky

Common problems we fix in Janetstown

Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly, and the problem shows up after you move in.

These are the problems we’re asked about most:

  • Plot mastic for developers ahead of handover
  • Skirting joints opening in the first winter
  • Sealant applied over dusty or wet surfaces
  • Frame joints opening as the plaster dries

If you’ve bought a new home near Thurso station, the sealant around baths, showers and frames is worth checking in the first year or two.
