New Build Mastic in Newcraighall
Professional new build mastic in and around Newcraighall, with old sealant always removed completely and a 12-month guarantee.
- Cracked sealant around new window and door frames
- Skirting joints opening in the first winter
- Beads laid onto grit and dust from the build
Keeping the joints in good condition
So the new joints stay in good condition:
- Keep water off fresh sealant until it has cured
- Use the extractor fan every time you shower
- Put sealant faults on your snagging list early
- Don’t wait for the house to settle if water is getting through
Keep photos of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you, so raise it early.
New build mastic in Newcraighall
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that’s reasonable, but a failed shower or bath seal shouldn’t wait. We work on skirting & floors, bathrooms & en suites 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.
Scotland’s cities are still adding new flats and houses, and new-home owners often find sealant snags in the first year or two.
The work is covered for a year after we finish. If anything is not right with it, email us at info@mrmastic.co.uk.

Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Hotels need rooms back in use, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
What happens on the day
You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the job takes a few hours for most snagging lists, longer for a run of plots for a typical job. For a tenement in Newcraighall, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. Tell us which applies when you book.
- Each joint is checked for movement before any work starts.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- Keep children and pets away from the work area
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive

Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
Do you work through snagging lists?
Yes. Photos of each sealant item help us quote. If something isn’t sealant, we will say so.
Can you quote for more than one area?
Of course. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.

New build mastic in Newcraighall: local notes
Newcraighall is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.
If you’ve bought a new home near Newcraighall station, the sealant around baths, showers and frames is worth checking in the first year or two.

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. Dealing with it early keeps the damage away from ceilings, floors and finishes. Scottish rain finds any gap around a frame or wall joint, and in a tall building in Newcraighall, damp can travel a long way before it shows.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
