Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Window mastic for homes and businesses in Pitkerro
There are two joints on most windows. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. If you are dealing with rushed sealant from a window installation and cracked or shrunken mastic around the frame, we can help, whatever the surface.
Tenement flats in Scotland’s cities often have windows high above the street, so the mastic outside can go unchecked for years. Access is the first thing to plan for a job in Pitkerro.
Every job is covered by a one-year guarantee.

How we quote for window mastic
You’ll get a clear quote before any work starts. It takes into account:
- The product the joint needs
- When we can work, for business premises
- The size of the job
- Whether old sealant or filler has to be cut out
We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please email us at info@mrmastic.co.uk and we will talk you through it.
What to tell us for a quote
To make quoting easier, let us know:
- How many joints, rooms or windows are involved
- What’s wrong with the joints now
- The address or postcode of the job
- Any previous sealing or DIY work
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we will talk you through the work and give you a clear quote.
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
How the job changes by surface
uPVC windows
We clean the frame edge carefully so the plastic isn’t marked, then the sealant goes in between frame and wall.
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that.
Common problems we fix in Pitkerro
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
Any of these means the joints need attention:
- Sealant in the wrong colour for the frame
- Cracked sealant at the sill ends
- Gaps left after new windows were fitted
- Old mastic that has gone black or come away
Rented homes near Dundee station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.
What to look for in a quote

Why it’s worth doing now in Pitkerro
If you’re painting or rendering, reseal at the same time. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. Wind-driven rain gets into any failed joint on the outside of a city building, and in a tall building in Pitkerro, damp can travel a long way before it shows.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why us?
- We leave the area clean and tidy
- 12-month guarantee on every job
- Old sealant always removed completely

Frames and glazing around Pitkerro
Pitkerro is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
If you live in an older home near St Ninian's Episcopal Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Managing a site like Craigie High School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Pitkerro questions
Who arranges sealant work on the shared parts of a tenement in Pitkerro?
Shared parts of a tenement, such as the roof and outside walls, are usually repaired with the agreement of the owners, often through a property factor. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Windows often belong to the individual flat, but it’s worth checking your deeds.
Can you help a landlord with a rental near Dundee station?
Yes, rental work is part of what we do. Just send an email to info@mrmastic.co.uk and tell us about the property, and we will give you a clear price.
How many windows can you do in a day?
That depends on the number of frames, how they’re reached and the state of the old mastic. We’ll tell you how long your job needs when we quote.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
What does window mastic cost?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Where are you based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
What happens on the day
On the day, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before work begins. Most jobs take a few hours for a few frames, or a day or more for a whole house. In a city area like Pitkerro, parking may be by permit or pay-and-display, so tell us what’s nearby. For flats, mention the door entry system and any shared-stair arrangements.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Let us know about parking restrictions
- Let us know about earlier repairs to the joints
