New build mastic for homes and businesses in Glenlochar
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. We work on bathrooms & en suites, plot handovers and show homes, and the jobs we see most are frame joints opening as the plaster dries and worktop and upstand sealant coming away.
For a place like Glenlochar, the journey and access are planned in advance. 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.

Different surfaces, different methods
Skirting and floors
As timber and screed dry, skirting and floors shift. Caulk cracks; a flexible sealant moves with it.
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. We reseal it with a weatherproof, flexible sealant.
What happens if it’s left?
The builder is normally the first port of call while the snagging or warranty period runs. If it keeps failing or isn’t dealt with, we can reseal it properly. 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 you pay reflects the work, not guesswork. That is why we ask about the job first.
What you get with us
- We’re fully insured
- 20+ years of sealant experience
- A sealant colour to suit the surroundings
- White, clear, grey or another colour, product permitting

How the visit works
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for most snagging lists, longer for a run of plots. Somewhere like Glenlochar may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Clear the area around the work

Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Leaking fittings rather than failed sealant
- Settlement cracks that need a surveyor
- Broken tiles or a split tray
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer.
Joints and surfaces we work on
- Windows & doors
- Kitchens
- Bathrooms & en suites
- Show homes
- Skirting & floors
- Plot handovers
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Wipe joints with warm soapy water
- Open a window or run the fan after bathing
- Do not wait for the house to settle if water is getting through
- Record problems with dated pictures
Avoid standing on the rim of the bath or the edge of the tray. If a bath or tray moves when you stand in it, get it looked at.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left.

DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
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.
