Tannadice Window Mastic
Mastic around window and door frames, sills and patio doors in Tannadice, with a one-year guarantee on every job. Call for a quick quote.
- Leaking joints at the ends of sills
- A bead that does not match the frame
- Untidy mastic left by window fitters
Different surfaces, different methods
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We seal the frame and let you know about anything else.
Window sills
Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. Each is cleaned out and resealed.
About our window mastic in Tannadice
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. Common call-outs are for rushed sealant from a window installation and black, perished sealant on frames, on aluminium frames, window sills and composite doors.
Outdoor sealant needs a dry surface, so window work around Tannadice is planned around the weather. Tell us about access to all the windows and doors, upstairs included.
A 12-month guarantee comes as standard, so you are covered after we’ve gone.

Windows and doors in Tannadice
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
In and around Tannadice, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Leave it or put it right?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly. 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.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.

Landlords, agents and businesses in Tannadice
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
We also work for property managers and facilities teams in Tannadice and across Angus. We can quote a run of properties together, and we are fully insured.
What we’re called out for in Tannadice
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.
Most people get in touch when they notice something like this:
- Gaps where the sill meets the wall
- Rushed sealant from a window installation
- White mastic on grey or black frames
- Draughts coming in around windows and doors
For an older house near a landmark such as Parish Church And Old Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

The process
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a morning for a couple of windows and a door. Around Tannadice, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed

Tannadice questions
What guarantee comes with window mastic in Tannadice?
All our work, in Tannadice and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Is Tannadice within the area you cover?
Yes. Tannadice is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover Tannadice, along with the rest of our area.
Can I do it myself?
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 does not work out, we can still put it right.
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.
What we cannot put right
In fairness, some problems need a different trade:
- Rotten timber, which needs a joiner first
- Penetrating damp from a failed cavity tray or render
- A sash or casement that will not close properly
If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer.
