"Amazing! They were very professional, kind and thorough. This was our second home inspection from them, as our first home offer fell through after the great inspection he did. He found things we wouldn't have otherwise seen. So we passed on the first home. With our second inspection, he gave precise and clear recommendations regarding what we'd need done in the future and we are so glad we found this company."
