For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over with a sealant suited to each area. We’re often asked to deal with smeared, uneven beads picked up at snagging and new-build shower sealant that has already split, on kitchens, bathrooms & en suites and skirting & floors.
Work in a place like Colmonell is planned ahead, journey included. Inside work goes ahead in any weather; outside mastic needs a dry day.
Your job is guaranteed for a year, as with all our work.

What we’re called out for in Colmonell
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints are not always given time to dry.
It’s worth asking for a quote if you see:
- Beads laid onto grit and dust from the build
- Gaps behind new kitchen upstands
- Messy sealant that spoils new finishes
- Sealant work across a run of new homes
For jobs in and around Colmonell, choosing the right material for each joint is as important as a tidy finish.

Joints and finishes in Colmonell homes
Colmonell is within about 3 miles of the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.
In and around Colmonell, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Should I go to my builder first?

What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
How much does new build mastic cost in Colmonell?
It depends on the job, so we quote each one individually. For a quick quote, email us at info@mrmastic.co.uk and tell us what needs doing and where.
What colour sealant will you use?
Most bathroom joints are white or clear, but other colours are available. We choose one to suit the room before we begin.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out 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.

How the visit works
When we arrive, we start by going over the job with you, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. Somewhere like Colmonell may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- 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.
- We check every joint and leave you with the cure times.
How to prepare

- Let us know about parking restrictions

What affects the quote in Colmonell
Every job gets its own quote. These are the things that affect it:
- The number of rooms or windows
- How much there is to do
- How easy the joints are to reach
- Whether old sealant or filler has to be cut out
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
What we need to know
When you contact us, these details help:
- Where the job is, and your postcode
- Pictures of the joints, sent by email
- Whether it has been sealed before
- How many joints, rooms or windows are involved
We don’t publish a price list, as no two jobs are quite the same. Instead, we give you a clear price for your job. To get started, send an email to info@mrmastic.co.uk.
What the job involves on each surface
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Show homes
In a show home, the sealant is on display. Every bead is neat and coloured to suit the room.
What sealant work cannot fix
We’d rather tell you now than do work that will not last, so these are the limits:
- Damaged fittings that need replacing
- Your warranty claim itself, which is between you and the builder
- Leaking fittings rather than failed sealant
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.
Joints and surfaces we work on
- Show homes
- Skirting & floors
- Plot handovers
- Bathrooms & en suites
- Kitchens
- Windows & doors
Looking after it afterwards
So the new joints stay in good condition:
- Keep water off fresh sealant until it has cured
- Avoid scourers and strong chemicals on sealant
- Resist patching a failed seal with a tube from the DIY shop
- Look at the sealant regularly in the first couple of years
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents, which can damage the surface.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you so report it promptly.
