New Build Mastic in Birnam
Problem with your new-build sealant joints in Birnam? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- New-build shower sealant that has already split
- Internal frame sealant that has split
- Untidy sealant flagged on a snagging list
How we handle new build mastic in Birnam
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. Both get the same care over preparation since hurried prep is behind a lot of new-build failures. If you’re dealing with beads laid onto grit and dust from the build and worktop and upstand sealant coming away, we can put it right.
Timber frame is common in newer Scottish homes, and it settles over the first years, so skirting and floor joints can open up. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
All of our work is guaranteed for twelve months, in Birnam and everywhere else we cover.

Questions from Birnam
I let a flat near Dunkeld & Birnam station. Can you help?
Yes, landlords and agents are among the people we work for. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear price.
Do you cover smaller places like Birnam?
Yes, we do. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Will you just run a new bead over the existing one?
No. We always remove the existing bead, the joint cleaned and primed where needed, before resealing.
How long should I leave it?
Cure times vary by product and the conditions. We tell you how long to leave it before we go.
How long will you be here?
That depends on how much there is to do, but most jobs take a few hours in a single home. We will give you a better idea when we quote.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Can you work from my snagging list?
Yes. We often work straight from a snagging list. We agree the sealant items with you before we start.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Keep photos and emails about snagging items
- Get a leaking seal dealt with right away
- Use the extractor fan every time you shower
- Clean sealant with mild detergent, not abrasives
Keep pictures of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and the new finishes intact.
For landlords and businesses
Landlords and agents in Birnam can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
When something else is needed
Sealant is not the answer to every problem, and we’ll tell you before work begins. Sealant will not put right:
- Disputes or warranty claims with your builder
- Cracking that points to a structural problem
- A tray or bath that isn’t properly supported, until it’s fixed
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly.
Surfaces we seal

What affects the cost of new build mastic
Every job gets its own quote. This is what makes a difference:
- Access and height
- Working hours on commercial sites
- Mould in or behind the old joints
- The amount of work
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.
What to tell us for a quote
When you call or email, these details help:
- Pictures of the joints, sent by email
- Any previous sealing or DIY work
- The rough size of the job
- Where the job is, and your postcode
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. When it suits you, send an email to info@mrmastic.co.uk.

Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Leave it or put it right?
A quick bead over the top of the old sealant can look fine at first, but it won’t bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What you get with us
- A choice of colours where the product allows
- Experience in homes, commercial sites and hotels
- Neat joints and a tidy finish
- A 12-month guarantee on all work
