A piece of flat stock aluminum slides in above the door in the frame, that prevents the door from being raised and popped out of the track.Windows get the L bracket in the tracks, double hung.

And I took the aluminum storm frames to the scrap metal yard and got around $25 for them. 

Doesn't look as good as vinyl siding or aluminum sheets but it's cheap.

I'm a Real Estate Investor in south eastern CT.  

I recently acquired 2 multi tenant properties in South Eastern Ontario, and I am looking for some good resources for things like credit checks, tenant screening, help with rental agreements, etc..As this is my first investment, I am looking at building my entire process from the bottom up.  

Window replacement business sometimes looks to me like the aluminum siding business did a few years ago.

He says we need to repair the sidewalks, driveway, paint the aluminum siding, reseed the lawn and do something about the patch of mulch from the tree.

My dad had invested in a couple of multifamily properties in the southeastern part of Massachusetts and was cash flowing pretty well, but between balancing a real estate portfolio and running his own construction business, most of his time was dedicated to his construction business.

In other words, instead of black, it will be either aluminum or stainless and will only enhance the space not detract from it -- HOPEFULLY.

But you don't want renters sticking aluminum foil in your windows.I would appreciate any guidance.
