About our new build mastic in Colinton Mains
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. We work on skirting & floors, windows & doors and kitchens, and the jobs we see most are sealant that never bonded to the surface and cracks appearing as a new home settles.
In older Scottish city flats, floors are often timber over joists, with skirting joints that open and close with the seasons. For a flat in Colinton Mains, a flexible sealant copes with that movement where filler would crack.
The work is covered for a year after we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
What happens if it’s left?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. Scottish rain finds any gap around a frame or wall joint, and in Colinton Mains, damp can spread through stone and plaster before anyone sees it.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and send you a clear quote before work begins.

For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will quote.
What we do, step by step
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a few hours in a single home. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In Colinton Mains, it helps to know the floor, the door entry arrangements and the nearest parking.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Mention any sign-in or site rules at work premises
- Tell us about any water getting in

Aftercare tips
Looking after new joints is easy:
- Photograph failed sealant before it’s redone
- Avoid running a DIY bead over the old one
- Check bath and shower seals every few months as the house settles
- Raise failed sealant with the developer while you’re covered
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it.
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.

Colinton Mains questions
Is new build mastic in Colinton Mains guaranteed?
All our work, in Colinton Mains and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Do you work for landlords with property near Slateford station?
Yes, we work for landlords and agents. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
Do you work through snagging lists?
Yes. Send the list and a few pictures of the sealant items and we’ll give you a quote. We’ll flag anything that needs another trade.
What does new build mastic cost?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before any work starts.
When is the best time to reseal in a new build?
That depends on the joint. A leaking shower or bath seal should be redone straight away, but cosmetic gaps can wait for movement to slow.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.
Should I go to my builder first?
Start with the builder if you’re in the snagging or warranty period. Once that is done, or if they won’t put it right, we’ll cut it out and reseal it.
Do you use white or clear sealant?
That depends on what the joint meets: white or clear for most sanitary joints, colours for worktops, floors and frames. We’ll agree it with you first.
