I need a dense exterior, preferably wooden door for my practice studio (Music) and I don't want to spend too much. Where can I catch a resonably priced used one in Montreal?
Answers:    Two ways to step about this. Check the links below. The first is to a pdf map on the city of Montreal website that indicates the locations of Ecocenters where on earth residents take what`s left from their renovations. Book yourself a Sunday afternoon ride and visit as various as you can. Each has a screened-off area set aside for articles in perfect enough shape for a second vivacity.
The second link is to the website of the TV show "Rebut global" roughly speaking building and renovating using the three R's. This particular page list the addresses of businesses that deal in used doors, windows and related hardware.
It`s kinda similar to buying used tires! Ya gotta ask yourself why the original owner carry rid of them?
Good ones are hard to find unless you know someone who`s doing a replacement and are aware of the condition and how they be used and abused.
You might try looking for building salvage establishments.
Contractors who deal surrounded by windows and doors.
Or conceivably just travel to the home improvement store and check out their discounted unit. Sometimes they have pretty perfect deals.
