How the visit works
Every visit runs the same way: we check the joints, protect the area around them, do the work and tidy away. It generally takes anything from a few hours to several days, depending on the number of plots. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Dawsholm, it helps to know the floor, the door entry arrangements and the nearest parking.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area
- Clear the area around the work

Advice
New build mastic in Dawsholm
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly instead of bonding to the dust. If you have messy sealant that spoils new finishes and joints pulling apart as timber shrinks, we can help, on plot handovers, windows & doors and skirting & floors alike.
Scotland’s cities are still adding new flats and houses, and in new homes, sealant and floor joints are often among the first snags.
There’s a 12-month guarantee on every job, whatever its size.

Signs you need new build mastic in Dawsholm
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly and cracked sealant shows up.
The most common problems we see are:
- Shower seals failing in the first year or two
- Sealant that never bonded to the surface
- Frame joints opening as the plaster dries
- Cracks appearing as a new home settles
If you’ve bought a new home near Kelvindale station, the sealant around baths, showers and frames is worth checking in the first year or two.

Surface by surface
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Plot handovers
Taking time over preparation reduces return visits. We clean out building dust before sealing and prime where the product needs it.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Dawsholm: your questions answered
Do you work for landlords with property near Kelvindale station?
Yes, rental work is part of what we do. You can email us at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before any work starts.
Is Dawsholm in your area for new build mastic?
Yes. We work across all of Scotland, and Dawsholm is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Will you just run a new bead over the existing one?
No. We always remove the existing bead, then clean and prime the joint, and a new bead applied.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Are you insured?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
What information do you need?
A short description and the location, with pictures by email if possible. We will ask anything else we need to know.
Is there any odour?
Some sealants have a smell while they cure. Ventilation helps.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
What new build mastic looks like in Dawsholm
The west of Scotland is wetter than the east, so there’s plenty of rain for plot mastic and the sealant in new homes to keep out. Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.
In and around Dawsholm, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How to look after the new joints
To keep the joints looking good and working properly:
- Open a window or run the fan after bathing
- Report sealant problems to your builder during the snagging period
- Wait for the cure time before using a resealed shower
- Avoid running a DIY bead over the old one
Clean the sealant with a mild detergent and a soft cloth. 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.
