How we handle new build mastic in Pettinain
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first. We work on show homes, kitchens and plot handovers, and common reasons people get in touch are gaps opening as the house dries out and settles and leaking shower tray seals in a new home.
Work in a place like Pettinain is planned ahead, journey included. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
Each job carries a 12-month guarantee, whatever its size.

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Keep pictures and emails about snagging items
- Raise failed sealant with the developer while you are covered
- Wait for the cure time before using a resealed shower
- Watch for new gaps as the house dries out
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents, which can damage the surface.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small.
Surface by surface
Windows and doors
Draughts around new frames are often a sealant gap. We check and reseal the frame edges.
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out and baths are filled before sealing.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.

Why deal with it now?
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times to plan around. In an older home around Pettinain, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Common problems we fix in Pettinain
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. As it does, timber shrinks and joints open, and sealant that can’t keep up splits.
These are the problems we’re asked about most:
- Gaps opening as the house dries out and settles
- Messy sealant that spoils new finishes
- Second-fix sealing on new plots
- Leaking shower tray seals in a new home
For new homes near Carstairs station, it’s worth checking the sealant early, while snags are still fresh.

FAQs for Pettinain
Can you help a landlord with a rental near Carstairs station?
Yes, we work for letting agents and landlords. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before we start.
Do you cover Pettinain for new build mastic?
Yes, Pettinain is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Where do you work from?
We work from Crawley. We cover Pettinain and the rest of South Lanarkshire.
What colour sealant will you use?
It depends on the joint: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before we start.
Should I go to my builder first?
Report it to the builder first while you’re covered. Once that is done, or if they will not put it right, we will cut it out and reseal it.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
When is the best time to reseal in a new build?
It depends on whether water is getting through. A leaking shower or bath seal should be redone straight away, while small cosmetic gaps can wait a while.
How the visit works
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on the number of plots. Outdoor work around Pettinain depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Mention if the joints have been sealed before
- Clear the area around the work
- Mention any tricky access
