Dropping heavy weights on concrete gets old fast, and once you put down proper rubber flooring, the whole room finally feels like a real gym instead of a cold storage space. The actual install usually takes just a weekend of cutting and laying tiles, and the best time to buy materials and book any help is right around the new year sales when suppliers clear inventory.
Before you hand over any money, get at least three quotes from local installers or check material prices across multiple suppliers so you know you are not overpaying. Once you have your numbers locked in, you can map out exactly how to handle the total cost.
Just remember that the 0% intro APR for 15 months on purchases and balance transfers is a hard deadline, not free money, and if any balance is left when those 15 months are up, you will get hit with interest on the original amount from day one.
