What the job involves on each surface

In a show home, the sealant is on display. We lay neat, even beads in colours to suit the finishes.
New build mastic for homes and businesses in Symington
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 and if that stalls, we can do it. Typical jobs include cracked caulk along new skirting and shower seals failing in the first year or two, on kitchens, show homes and skirting & floors.
New homes in smaller Scottish places are often single plots, self-builds or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
Big or small, it’s backed by our 12-month guarantee in Symington and across South Lanarkshire.

Common problems we fix in Symington
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak and it shows once the home is in use.
Common reasons people contact us are:
- Sealant that never bonded to the surface
- Kitchen sealant that has pulled off the wall
- Cracks appearing as a new home settles
- Plot mastic for developers ahead of handover
In and around Symington, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

New homes and floors in Symington

FAQs for Symington
Do you cover smaller places like Symington?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
What guarantee comes with new build mastic in Symington?
All our work, in Symington and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
Can you match the sealant colour to my new kitchen or bathroom?
White and clear are the most common, but sealant comes in other colours too. We choose one to suit the room.
How long should I leave it?
Cure times vary by product and the temperature. Before we leave, we will tell you the cure time.
Where is Mr Mastic based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Should I wait before resealing?
It depends on whether water is getting through. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
What happens on the day
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we have agreed what’s being done, we protect the area and start. It normally takes a few hours for most snagging lists, longer for a run of plots. Somewhere like Symington may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- 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.
Preparing for the visit
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Get a leaking seal dealt with straight away
- Use the extractor fan every time you shower
- Record problems with dated photos
- Avoid running a DIY bead over the old one
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.
Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you.
Why it’s worth doing now in Symington
Resealing everything on a snagging list in one visit is usually simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times. Around Symington, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
Why Symington clients choose us
- White, clear, grey or coloured to suit, where the product allows
- A sealant colour to suit the surroundings
- ARBOMaster approved applicator
- Neat joints and a tidy finish
