Blocks and managed buildings in Ninewells
With the shore within about 1 mile, Ninewells counts as a coastal location. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do; plan inspections around that. The 2 miles around Ninewells include six care or nursing homes. Owners of care premises can bring window and door mastic into a phased programme planned around the home.
Older buildings near Ninewells, from historic houses such as Camperdown House (1.5 miles north of Ninewells) to more modest stock, need compatible products when frames are resealed. Site managers at schools like Menzieshill High School can fit frame mastic into the summer works.

Mastic sealing for commercial buildings in Ninewells
For blocks and buildings in Ninewells and across Dundee, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. A list of buildings, a few photos and approximate joint numbers are enough for a quick quote, and site visits can be arranged. If you’re dealing with damp patches beside frames and mastic failing across several blocks on an estate, we can put it right, on external wall and movement joints, balcony and threshold joints and communal entrances and stairwells alike. A single leaking joint is often how a building in Ninewells first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Sandstone tenements in most Scottish cities, and granite in Aberdeen, need mastic that suits the stone, and replacement windows set into those walls need a perimeter sealant that won’t mark the stone.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Your questions answered
How do tenement owners in Ninewells get shared-part mastic done?
In most tenements, the owners agree shared repairs, and many use a property factor to arrange them. One quote can cover a close or the whole block.
Does the sea air around Ninewells change the choice of sealant?
It can. Coastal exposure works external joints harder than inland weather. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
How do you choose the sealant?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
How do we ask for a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.
Can people stay in the building while you reseal?
The work is planned around occupiers. We agree the programme so you can notify occupiers, and entrances stay in use.
How long do sealant joints last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
How a job runs
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. University, hospital and office estates in Scotland’s cities have their own permits, inductions and sign-in rules. Tell us the rules and we will work to them.
- We inspect each building and record the joints that have failed.
- You get a fixed quote, per block or for the whole programme.
- We agree the programme and dates with you.
- Old mastic is removed and the joint faces prepared.
- New sealant goes in with backing rod and primer where needed.
- We check the finished work and confirm the guarantee.
Getting the site ready
- Move anything stored against the joints
- Point out any areas we must not close

Signs you need mastic sealing in Ninewells
Much failed sealant was laid on dirty, dusty or damp surfaces. Without clean, sound faces and a primer where the product needs one it comes away from one face.
These are often picked up first by site or facilities staff:
- Mastic failing across several blocks on an estate
- No planned programme for sealant
- Leaks at window and door perimeters
- Occupiers reporting cold air round windows
If you own or manage units on a site such as Dundee Technology Park (0.6 miles west of Ninewells), failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

Doing it in-house
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Keeping the joints sound
A few simple habits keep the new joints working:
- Look at the sunniest and most exposed elevations first
- Track which buildings were done and when
- Keep bins and bikes away from communal door frames
- Share your contractor requirements early
Where a paintable product was specified, it can be painted after curing. Silicone usually can’t be painted, so keep decorators off it unless told otherwise.
Leaks at window perimeters spoil finishes and can affect frames. Early resealing is far simpler than repairs inside.
