About our new build mastic in Shulishader
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. We work on show homes, windows & doors and kitchens, and people most often call us about cracked caulk along new skirting and new-build shower sealant that has already split.
Many newer homes in Scotland are timber-framed and settle as they dry out, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

What sealant work cannot fix
We’ll always be straight with you, so here’s what new sealant won’t do:
- Your warranty claim itself, which is between you and the builder
- Settlement cracks that need a surveyor
- Leaking fittings rather than failed sealant
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think.

What affects the cost of new build mastic
There’s no set price list, because jobs vary so much. The quote depends on:
- The product the joint needs
- Whether old sealant or filler has to be cut out
- The number of rooms or windows
- The number and length of the joints
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, send an email to info@mrmastic.co.uk and we’ll give you an honest view and a quote.
Helping us quote
What to tell us when you ask for a quote:
- How we’d reach the joints
- The address or postcode of the job
- A few photos by email, if you can
- What the problem is, such as mould, gaps, leaks or cracking
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.
What we’re called out for in Shulishader
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
It’s worth asking for a quote if you see:
- Second-fix sealing on new plots
- Gaps between new skirting and floors
- Joints pulling apart as timber shrinks
- Worktop and upstand sealant coming away
In and around Shulishader, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What to look for in a quote
- How the joint is cleaned and prepared
- Which sealant they’ll use, and why
- Who turns up on the day
- When the joint can take water or movement
For landlords and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works.
If you manage several properties in or around Shulishader, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs.
DIY versus a professional finish
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.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
What happens on the day
You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a few hours in a single home for a typical job. Outside jobs in Shulishader need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely down to clean surfaces.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
How to prepare
- Keep children and pets away from the work area
- Let us know about stairs, lifts or work at height
- Let us know if you’ve seen damp or leaks

Kitchens

Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant.
New homes and floors in Shulishader
Shulishader is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Island jobs need planning around ferries and the weather, so give us as much notice as you can.
Whether the job is in Shulishader itself or nearby, the right material for each joint matters as much as a neat finish.
