What the job involves on each surface

Skirting and floors

As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk in a colour to suit.

Bathrooms and en suites

Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.

How we handle new build mastic in Greenhills

Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover with a sealant suited to each area. We work on kitchens, show homes and plot handovers, and common reasons people get in touch are gaps opening as the house dries out and settles and messy sealant that spoils new finishes.

Many newer homes in Scotland are timber-framed and settle as they dry out, so skirting and floor joints can open up. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.

You’re covered for a year from the day we finish. If anything is not right with it, drop us a line at info@mrmastic.co.uk.

What happens if it’s left?

Running a new bead over the builder’s sealant might look tidy for a few weeks, but it cannot bond to what’s underneath. A lasting seal starts with removing the old one completely. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

How it works

Every visit runs the same way: we check the joints, protect the area around them, carry out the job and clear up. Most jobs take a few hours in a single home. Around Greenhills, distance and access matter more than parking. Tell us how to find the property and how to reach the work.

  1. First we work through your snagging list or plot schedule with you.
  2. The old bead comes out in full, with no layer left behind.
  3. Each joint is cleaned of dust and grit, then primed if required.
  4. We apply a sealant that suits each joint and tool it to a neat finish.
  5. Finally, each room is checked and you’re given the cure time.

Before we arrive

  • Mention any tricky access
  • Tell us about any previous sealing or DIY attempts
  • Keep children and pets away from the work area

Looking after it afterwards

No joint lasts for ever, but care makes a real difference. Our tips:

  • Avoid running a DIY bead over the old one
  • Check bath and shower seals every few months as the house settles
  • Keep pictures and emails about snagging items
  • Do not wait for the house to settle if water is getting through

Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it, which can damage the surface.

If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.

Quotes for new build mastic in Greenhills

Some jobs are bigger than they look, and some smaller. The main factors:

  • Whether old sealant or filler has to be cut out
  • Working hours on commercial sites
  • The number of rooms or windows
  • The number and length of the joints

There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please email us at info@mrmastic.co.uk.

Asking for a quote

When you call or email, these details help:

  • Whether it’s a home or a business
  • Any previous sealing or DIY work
  • A few pictures by email, if you can
  • The rough size of the job

Honest limits

New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:

  • Plumbing faults behind the sealant
  • A tray or bath that isn’t properly supported, until it’s fixed
  • Settlement cracks that need a surveyor

Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly before booking.

New homes and floors in Greenhills

Greenhills 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. Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.

In and around Greenhills, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What we are called out for in Greenhills

A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open and the sealant has to cope with the movement.

Signs it’s time to call us include:

  • Skirting joints opening in the first winter
  • Second-fix sealing on new plots
  • Sealant applied over dusty or wet surfaces
  • Smeared, uneven beads picked up at snagging

For new homes near Dunlop station, it’s worth checking the sealant early, while snags are still fresh.

What to look for in a quote

  • Who does the work, and how experienced they are
  • Whether all the old sealant comes out first
  • Is VAT in the price?
  • Whether you can choose the colour

10 questions to ask before you book

Common questions in Greenhills

I let a flat near Dunlop station. Can you help?

Yes, rental work is part of what we do. You can email us at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.

Do you cover Greenhills for new build mastic?

Yes, Greenhills is within the area we cover. We work across all of Scotland. You can email us at info@mrmastic.co.uk and tell us what needs doing.

How long will you be here?

Typically it takes a few hours in a single home. Larger jobs naturally take longer, and we will say how long yours will take.

Should I go to my builder first?

If you’re still within the builder’s snagging or warranty period, report it to them first. If they’re slow or the fix does not last, we can help.

Is there any odour?

It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.

What information do you need?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

Are you fully insured?

Yes. We are fully insured, and we can confirm the details when we quote.

Can new sealant go on top of the old bead?

No. New silicone won’t bond to old silicone, so it soon lifts and traps water. The old sealant always comes out first.
