Retaining Wall testimonial

“I’d been looking for someone to stabilize and level my back yard off and on for about ten years and, before I found Dochnahl, I was getting pretty frustrated with the level of knowledge I was finding.  I had an erosion problem and, as my back yard was largely fill, I needed someone who understood how to support the retaining wall with pilings, and also how to provide for proper water drainage.  Not only does Dochnahl have the knowledge and experience, they listened to my ideas, and offered more cost-effective ways to turn them into reality.  I now think of Dochnahl more as friends than contractors, and give them the highest recommendation.”
