I had a mason and a contractor come out and look at it, and they seem to think they can fix the issue, but I don't think they'll shoulder the liability.So, with all that said, what would you all recommend is the best, most cost effective (both short and long term) way to handle this?

They said if turned out bad, at least you had somebody's shoulder to cry on. 

From an entrepreneurial perspective, trying to be the CPA, CTO, and COO for your company is just not very time efficient when you can be spending your time on more income generating activities and building a team that can shoulder the work for you.

However, the attorney has a Mustang Cobra convertible & Zeus rides in the passenger seat a full head & shoulders above the windshield, so if he had to brake hard Zeus would be a very large hood ornament.Both often complain about the rearranging of furniture as the dog bounds through the home knocking any obstacles asunder but I assume some form of obedience training will prevail.

Unfortunately my sister is not there 24/7 and she fell again shattering her shoulder in 10 places.

Obviously, I can not view MLS directly and WOULD NEVER look over her shoulder, but can have HER look it up.), I can get Days on Market, telling me how itchy to unload they are.

One of my favorite quotes is by Isaac Newton, "If I have seen further than others, it is by standing upon the shoulders of giants".

The mere fact that you are out of warranty, Lowes doesn't have to do you any favor whatsoever, that is the solid hard truth, they are not in breach as the agreement only lasts 12 months, if you used it and broke down within the 12 months, then it is a manufacturer defect, it will be on their shoulder, after that, its on you, you cannot expect the retailer to carry anything more than the agreement, you have the choice to extend the warranty if you so choose. 

You seem to have a good head on your shoulders, use it.
