The amount of money you spend each month on energy costs may seem like a fixed amount, but many local utility companies provide free energy audits of their customers' homes. They can show you how to maximize the energy efficiency of your home. An energy-efficient home will save you money now, which can be applied to other updates, and is a more valuable and marketable asset in the long run.
Any good contractor will have no problem providing references, and copies of liability insurance before a job begins. Don’t rely solely on client testimonials, search out actual customers that can give you a firsthand account and answer any questions you may have. For any project, ask to see before and after images of a contractor’s prior work, and most importantly—trust your gut and know which questions to ask.
