Get matched with top architects in Antioch, CA

"I am a Realtor and was representing Sellers. The Buyers in athe transaction wanted $16,500 for foundation work based on a report from a foundation inspection company. My property inspector and an architect friend felt the report was completely in error. I called Home Advisor and Padir responded. The inspector came out the same day; charged a very reasonable price and delivered a professional 17 page report. We gave that to the Buyers Realtor and settled on a very small credit based on the report from Padir."
