I have used Steve Smith and Associates for several things. His office is on Lily Pond road in Gilford. He is a nice guy and a straight shooter.

Within the past two weeks I was told by the City of Laconia that their sewer line ran through my property, right where a new building was going to go. They even sent me a plan and an aerial photo with the sewer line shown on it.
Steve Smith said they were wrong and the plan they had sent me was wrong. He sent two men to my land to confirm it and then contacted the city and told them their plan was wrong. He gave them a new plan with the sewer line correctly located on it.
