About our new build mastic in Coulport
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. If you have beads laid onto grit and dust from the build and kitchen sealant that has pulled off the wall, we can help, whatever the surface.
For a place like Coulport, the journey and access are planned in advance. Inside work goes ahead in any weather; outside mastic needs a dry day.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Why act early in Coulport
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or is not dealt with, we can reseal it properly. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before we start, so you know where you stand.
Why us?
- 20+ years of sealant experience
- ARBOMaster approved applicator
- Old sealant always removed completely
- A 12-month guarantee on all work

FAQs for Coulport
Do you cover Coulport for new build mastic?
Yes, Coulport is within the area we cover. Our work covers the whole of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job, and we will give you a clear price.
Is Coulport within the area you cover?
Yes, Coulport is covered. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we’re using and why.
Do you take on second-fix sealing for builders?
Yes. We take on second-fix sealant work across new plots. We clean and prime joints properly to keep callbacks down.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
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 right away, while small cosmetic gaps can wait a while.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.

Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Open a window or run the fan after bathing
- Wait for the cure time before using a resealed shower
- Avoid running a DIY bead over the old one
- Act quickly if a seal starts to leak
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Early snagging is easier snagging. Left alone, a small crack can become a leak in a busy bathroom.
