Common questions in Alyth
What guarantee comes with new build mastic in Alyth?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Is Alyth within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses, and we are fully insured.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Are you insured?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
Can landlords and businesses book you?
Yes, often. Several properties can go on one quote, and between tenancies is a good time for the work.
Can new sealant go on top of the old bead?
No. Fresh silicone does not stick to the old layer, so sealing over the top fails quickly. The old sealant always comes out first.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
New build mastic for homes and businesses in Alyth
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation, because that is what rushed new-build sealant normally lacks. Common call-outs are for gaps behind new kitchen upstands and new-build shower sealant that has already split, on plot handovers, skirting & floors and windows & doors.
Many newer homes in Scotland are timber-framed and settle as they dry out, which shows as gaps at skirtings and floor joints. In older homes, timber floors move through the year too.
You’re covered for a year from the day we finish. If anything isn’t right with it, send an email to info@mrmastic.co.uk.

What we are called out for in Alyth
A new house holds a lot of water from the build, which takes a year or two to dry out. As it does, timber shrinks and joints open.
Look out for any of the following:
- Sealant applied over dusty or wet surfaces
- Gaps opening as the house dries out and settles
- Smeared, uneven beads picked up at snagging
- Plot mastic for developers ahead of handover
In and around Alyth, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before booking
- What product goes in the joint
- What happens if they find a problem under the old sealant
- How the surfaces are prepared before sealing
- Is the old sealant removed completely?

What affects the cost of new build mastic
We quote each job individually. These are the things that affect it:
- Any mould that needs treating
- Whether the work is at height
- The size of the job
- The number of rooms or windows
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
Helping us quote
You do not need to know the technical terms. Just tell us:
- Where the property is
- Photos by email, if that is easy
- Access, such as stairs, a lift or height
- The rough size of the job
Need a quote? Please send an email to info@mrmastic.co.uk with a few details. We will explain what we’d do and give you a clear quote before we start.
What happens if it’s left?
The builder is usually the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In an older home around Alyth, damp from a failed joint can get into timber and plaster.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
Why us?
- Neat joints and a tidy finish
- Old sealant always removed completely
- Every job guaranteed for a year
- Domestic, commercial and hotel work

What sealant work can’t fix
To be straight with you, some problems need a different trade:
- Cracked trays, tiles or worktops
- Leaks from pipes, valves or wastes, which need a plumber
- Settlement cracks that need a surveyor
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before booking.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Looking after it afterwards
So the new joints stay in good condition:
- Avoid running a DIY bead over the old one
- Wipe joints with warm soapy water
- Raise failed sealant with the developer while you are covered
- Keep water off fresh sealant until it has cured
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. Report any movement in a bath or tray.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.
What we do, step by step
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours in a single home, depending on the size of the job. Outside jobs in Alyth need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- 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 leaks or damp you’ve noticed
- Move anything stored near the joints
- For indoor joints, keep the area dry beforehand if you can
