Mollinsburn New Build Mastic
Professional new build mastic in and around Mollinsburn, with every bit of old sealant taken out first and a 12-month guarantee.
- Shower seals failing in the first year or two

Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
New build mastic in Mollinsburn
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that is reasonable, but a seal that is letting water through needs doing now. We are often asked to deal with leaking shower tray seals in a new home and sealant applied over dusty or wet surfaces, on plot handovers, skirting & floors and windows & doors.
New homes in smaller Scottish places are often single plots, self-builds or small developments. They need their sealant and floor joints finished just as carefully as on a big site.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

How the job changes by surface
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. We reseal it with a weatherproof, flexible sealant.
Plot handovers
Plot mastic is carried out to the developer’s schedule. Each joint is cleaned and primed where needed.
Leave it or put it right?
A tube of sealant from the DIY shop won’t fix the cause: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. In a place like Mollinsburn, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

- The number and length of the joints
- How many rooms, windows or areas are involved
- How easy the joints are to reach
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.

You do not need to know the technical terms. Just tell us:
- Where the property is
- How many joints, rooms or windows are involved
- Whether it has been sealed before
- Pictures of the joints, sent by email
For a quick quote, get us on the phone, or email us if that’s easier. Describe what needs sealing and we’ll explain what’s involved before giving you a price.
What we do, step by step
There is not much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours in a single home, including the tidy-up. Outside jobs in Mollinsburn need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Preparing for the visit
- Let us know about parking restrictions
- Let us know if you’ve seen damp or leaks
- Move anything stored near the joints

Aftercare tips
A little care helps the new joints last. Our advice:
- Clean sealant with mild detergent, not abrasives
- Open a window or run the fan after bathing
- Keep pictures and emails about snagging items
- Don’t wait for the house to settle if water is getting through
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing to help keep mould away.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant.
When it is not the sealant
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Cracking that points to a structural problem
- Disputes or warranty claims with your builder
- Movement caused by a poorly fitted tray or bath
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly.
