New build mastic in Straiton
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. We work on windows & doors, show homes and skirting & floors, and common reasons people get in touch are gaps behind new kitchen upstands and sealant work across a run of new homes.
Around smaller Scottish places like Straiton, 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.
Your job is guaranteed for a year, as with all our work.

- Structural cracks in walls or ceilings

How the visit works
You do not need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on the number of plots in most cases. Outside jobs in Straiton need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely.
- We clean out the dust and grit left from the build.
- 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.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any water getting in
- Keep children and pets away from the work area

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Get a leaking seal dealt with right away
- Check bath and shower seals every few months as the house settles
- Avoid running a DIY bead over the old one
- Ventilate bathrooms well, especially in the first year
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you, so raise it early.
Landlord and commercial work in Straiton
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
FAQs for Straiton
Is Straiton within the area you cover?
Yes. Straiton is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is new build mastic in Straiton guaranteed?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Where is Mr Mastic based?
We work from Crawley. We cover Straiton and the rest of South Ayrshire.
Can you work from my snagging list?
Yes. Photos of each sealant item help us quote. If something isn’t sealant, we’ll say so.
Is it worth resealing while the house is still settling?
Where water is getting through, don’t wait. Hairline cosmetic gaps can wait until the house has settled.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Different surfaces, different methods
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We remove cracked sealant and apply a flexible one.
Plot handovers
Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing.
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
How we quote for new build mastic
We quote each job individually. This is what makes a difference:
- The old material and how stubborn it is
- How easy the joints are to reach
- The amount of work
- When we can work, for business premises
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.
What to tell us for a quote
To help us quote quickly, please include:
- Any previous sealing or DIY work
- What’s wrong with the joints now
- The type of property
- Photos by email, if that’s easy
There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, send an email to info@mrmastic.co.uk.
New build mastic around Straiton
Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up. Straiton is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for plot mastic and the sealant in new homes to keep out.
In and around Straiton, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. For jobs in and around Straiton, choosing the right material for each joint is as important as a tidy finish.
