We were fortunate to have [Helmutz] back for the 4th time to work on yet another project for us.  As with every project we’ve had them work on the crew were polite, efficient, respectful and always diligent with their end of day clean up. They worked with us to bring to life our vision throughout the design process. Helmutz stands by the quality of their work as well as product. We would highly recommend Helmutz for any landscaping, driveway project!

I had Helmutz install a stone walkway along my driveway and around the front porch, and I'm very pleased with the results! Eric (and the whole team) was easy to work with from outset to install; professional, responsive, patient, and considerate of my design & accessibility goals. Plus, they were able to accommodate scheduling around other landscaping projects, which was super helpful.

Your whole company worked so hard, and never slacked.  The attention to detail was amazing, but the personal touch of always chatting up the kids helped too.    Mark was such a rockstar through it all - and we appreciated his ability to tackle things head on.  Erinne; your design is absolutely STUNNING! You absolutely NAILED this job!  Truly, you have a real talent for this.

We have been so pleased with Helmutz Landscape and Interlock through every step of the process.  From our initial email and first appointment with Helmut, to our appointment at the shop, and the amazing turnaround time.  The crew was amazing, fast, knowledgeable, tidy and pleasant. Then of course you were so amazing to find a solution to our concerns and fixed them right away!

Helmutz did a great job building our retaining wall. They were quick and efficient, and took very good care of the surroundings and property while doing so. We would definitely have them do any future landscape projects.
