This book is great and saved me thousands of dollars. I was about to hire a company to dig out around my house to repair basement leaks, but luckily I read this book first. I was able to do a few simple repairs to my gutters (turns out my downspouts were not going away from my house) and make a few other easy landscaping changes and the leaking stopped.I would strongly suggest making the small investment to educate yourself on what is causing the leaks (which this book will do with example photos) before having a company come in and dig up your yard for thousands of dollars (trust me, that was their only suggestion).
