New build mastic in Alloway, done properly
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. If you’re dealing with sealant that never bonded to the surface and worktop and upstand sealant coming away, we can help.
Work in a place like Alloway is planned ahead, journey included. Inside work goes ahead in any weather; outside mastic needs a dry day.
You are covered for a year from the day we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

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. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.

What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours in a single home. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Getting ready for the visit

What affects the quote in Alloway
The quote reflects the job in front of us. We take into account:
- Any working-time requirements on site
- Whether the work is at height
- The old material and how stubborn it is
- The number of rooms or windows
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What to tell us for a quote
Before you ask for a quote, have a think about:
- The rough size of the job
- Where the property is
- What’s wrong with the joints now
- If someone has resealed it before

Different surfaces, different methods
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. A proper reseal keeps water in the tray.
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish to a tidy standard. We’ll plan around viewing times.
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Resist patching a failed seal with a tube from the DIY shop
- Record problems with dated photos
- Open a window or run the fan after bathing
- Avoid scourers and strong chemicals on sealant
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it, which can damage the surface.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
Questions from Alloway
Will you come out to Alloway?
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.
Do you work for landlords with property near Ayr station?
Yes, rental work is part of what we do. Just email us at info@mrmastic.co.uk and tell us about the property, and we will send you a clear quote.
How long will you be here?
Most jobs take a few hours for most snagging lists, longer for a run of plots. Your quote will say how long we expect yours to take.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
Can new sealant go on top of the old bead?
No. We always remove the existing bead, the joint cleaned and primed where needed, before resealing.
Is the work guaranteed?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
When is the best time to reseal in a new build?
Where water is getting through, don’t wait. Hairline cosmetic gaps can wait until the house has settled.
Why has my new-build shower seal failed already?
New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.
What new build mastic looks like in Alloway
Alloway is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Alloway 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.
Around Alloway, as everywhere, new build mastic is only as good as the preparation behind it. If you’ve bought a new home near Ayr station, the sealant around baths, showers and frames is worth checking in the first year or two.
