Payment. If you want the installation of your hardwood floors done right, its best to be prepared to consider this an investment in your home. Consider visiting as many hardwood flooring stores as you can so you can get the best price for what you want. You may find that if you cannot afford to pay cash for the entire project, companies like Home Depot will offer to finance the job for you, often with no payments for several months.
Be sure to read the fine print, as you may find that often, there is an expensive interest rate factored in if the full balance isn't paid in full. Of course, there is also credit cards and lines of credit that you can use, but watch out for high interest charges. Its usually best to plan ahead, create a budget, and pay it off either in cash, or before the interest rates kick in.
Sensibility. While I'm all in favor of having hardwood floors in every room, you have to take a minute and think about what rooms are suited for them. Does the room have high humidity? Is it water prone? If you even think that the answer is yes, then the room is not suited for hardwood floors.
Installation. Today you can find hardwood floors that are rather simple to install on floors that are absolutely flat. If you are fortunate enough to have these kinds of floors (most of us do not) it might be well worth the money to hire a professional flooring installer who has the skills to level your floors in the process.
It is quite likely that any decision you make when it comes to hardwood floors for your home will provide you with beautiful floors that should serve your family for many years to come.
