New build mastic in Alva
We work in new homes and on new-build sites across Alva. One shower or a whole phase of plots, the method doesn’t change: remove, clean, prime where needed, then a neat new bead. Common call-outs are for untidy sealant flagged on a snagging list and joints pulling apart as timber shrinks, on show homes, windows & doors and skirting & floors.
Timber frame is common in newer Scottish homes, and it settles over the first years, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
A one-year guarantee comes as standard.

Your questions about new build mastic in Alva
Is Alva within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Alloa station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
How do I get a quote for new build mastic in Alva?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Can you do plot mastic on a new development?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send us the plot schedule and we will quote.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Are you fully insured?
Yes. We’re fully insured for every job we do.
Why does sealant fail so quickly in new builds?
New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Surface by surface
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. We reseal it with a weatherproof, flexible sealant.
Skirting and floors
As timber and screed dry, skirting and floors shift. Caulk cracks; a flexible sealant moves with it painted or coloured to suit.
Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, 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.
New build mastic in Alva: local notes
Alva is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.
Around Alva, as everywhere, new build mastic is only as good as the preparation behind it.

Do you need new build mastic in Alva?
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes do not always leave time for joints to dry before the sealant goes on.
The most common problems we see are:
- Cracks appearing as a new home settles
- Frame joints opening as the plaster dries
- Worktop and upstand sealant coming away
- New-build shower sealant that has already split
If you’ve bought a new home near Alloa station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before booking
- Whether they seal over old material or remove it
- How long to leave it before use
- Which sealant they’ll use, and why
- How the surfaces are prepared before sealing
How we quote for new build mastic
The quote reflects the job in front of us. We look at:
- Any working-time requirements on site
- The size of the job
- Access and height
- The old material and how stubborn it is
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Asking for a quote
Photos help, but a description is a good start. Please mention:
- Access, such as stairs, a lift or height
- What’s wrong with the joints now
- The rough size of the job
- Where the property is
We quote each job on its own, so start by telling us what you need. Just drop us a line at info@mrmastic.co.uk with the details, and photos are welcome.
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Ventilate bathrooms well, especially in the first year
- Don’t wait for the house to settle if water is getting through
- Raise failed sealant with the developer while you are covered
- Keep pictures and emails about snagging items
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry and can be resealed later.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in saves a harder job later.
What we do, step by step
We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes anything from a few hours to several days, depending on the number of plots. Around Alva, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area
- Tell us about any water getting in
How to get a quote
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand, and we will take it from there.

Why deal with it now?
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 for the lot. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.
