Common questions in Roslin
Will you come out to Roslin?
Yes, Roslin is covered. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I let a flat near Eskbank station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
Is it normal for sealant to crack in a new home?
Lots of new homes see sealant crack early. Rushed application on dusty surfaces makes it worse.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. Then drop us a line at info@mrmastic.co.uk.
Can you do plot mastic on a new development?
Yes. We take on second-fix sealant work across new plots. Good preparation keeps snagging to a minimum.
How much does new build mastic cost in Roslin?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.
Do the sealants smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and you will get one quote.
Keeping the joints in good condition
So the new joints stay in good condition:
- Resist patching a failed seal with a tube from the DIY shop
- Watch for new gaps as the house dries out
- Wipe joints with warm soapy water
- Photograph failed sealant before it’s redone
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries and can be resealed later.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant.
How we quote for new build mastic
Call for a quick quote. The main things that affect it are:
- The size of the job
- How easy the joints are to reach
- Any mould that needs treating
- The old material and how stubborn it is
Doing several joints on one visit generally makes better use of the time than several visits. You’ll get one clear quote for the whole job.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- Any access issues, like height or stairs
- Where the property is
- If someone has resealed it before
- Whether it’s a home or a business
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. When it suits you, drop us a line at info@mrmastic.co.uk.
Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Different surfaces, different methods
Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk painted or coloured to suit.
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.

What else we do in Roslin
How the visit works
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for most snagging lists, longer for a run of plots for a typical job. Around Roslin, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you’re given the cure time.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Tell us about access, such as stairs, a lift or high-level joints
- Keep pets and children clear of the area while we work

What new build mastic looks like in Roslin
Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.
In and around Roslin, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. For new homes near Eskbank station, it’s worth checking the sealant early, while snags are still fresh.

What we can’t put right
A few problems are outside what sealant work can do:

Leave it or put it right?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. In an older home around Roslin, damp from a failed joint can get into timber and plaster.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, email us at info@mrmastic.co.uk for an honest opinion and a quote.
