As the previous review stated, this company Greentech and their other company names includnig, GiantDoor manufacturing inc, and are the same owners. Asi and Sean (the owners) think they are getting away with not providing the required follow up customer service. Their doors are poor quality. They don't return calls or emails. In the end karma will fix these guys and word travels fast, especially on social media. All my associates and contacts will know about and be warned to avoid these guys. Don't order any doors or windows from these people.
