They're very thorough and they do it right the first time. Their estimates were a little on the high side but you're paying for quality work instead of a sloppy job that has to be redone.

I like their personal, down-to-earth approach.

Comparative Summary

Maintaining customer satisfaction is a crucial aspect of any business, but it’s even more important for drainage contractors that have earned the prestigious Diamond Certified award. For Devengenzo Landscaping & General Engineering Inc., the key to achieving and maintaining high levels of customer satisfaction is simple: focus on exceeding expectations at every level of its service, regardless of the size of the project. “We offer personalized service, attention to detail and cleanliness on every job,” says President Robert Devengenzo. “Our goal is to make every project as close to perfect as possible–not just mechanically, but visually as well.”

Devengenzo Landscaping & General Engineering has been providing construction, engineering, and landscaping services for residential and commercial clients in Contra Costa, Solano and Alameda Counties since 1970. The company is known for its expertise in surface and subsurface drainage, but it also has the training and equipment to renovate kitchens and bathrooms, repair damage caused by landslides, install automated irrigation systems, work on sewer systems, and more.

Unlike contractors that focus on a specific aspect of the industry and limit their services as a result, Devengenzo Landscaping & General Engineering holds three separate licenses (landscaping, general engineering and general contracting) so it can provide its clients with complete indoor and outdoor construction services, from drainage systems and yard grading to whole house remodels and landscaping. “We have the experience and knowledge to solve any problems that our customers experience,” affirms Mr. Devengenzo.

To further differentiate itself from its competition, Devengenzo Landscaping & General Engineering provides every project with the hands-on expertise of both Mr. Devengenzo and his son, Nick. “We’ve been in business for a long time, but we’re still small and hands-on,” he says. “My son and I run all the jobs and manage the whole process step-by-step, which our clients really appreciate.”

Industry Info

Take simple steps to ensure your home drainage system lasts as long as possible. First, confirm that your home builder or drainage contractor installed high-quality products in your drainage system. Some companies will use corrugated piping, which collects debris and causes system backups. It’s important to request a smooth wall drainage pipe with a high crush rating. SDR-35 pipe is very durable, resistant to debris buildup and easy to flush out.

According to Robert Devengenzo, president of Devengenzo Landscaping & General Engineering Inc. in Lafayette, you should have a clean out at every downspout, and the entire system should be flushed with water in the spring and fall. Systems should be installed with Sanitary Tees, Wyes, 45-degree fittings, and 22-degree fittings so they can be cleaned and flushed. Don’t use 90-degree fittings or straight Tees.

Surprisingly, even some high-end home builders use inferior products on drainage systems—they only guarantee their work, not their products, so their customers have no recourse for the cheap materials when they face drainage issues years down the road. To avoid this situation, Mr. Devengenzo says it’s important to carefully interview contractors and drainage companies before hiring. “Ask how long they’ve been in business, what experience they have and if they’ll give you recent references. Make sure you call a range of references and find out if they were happy with both the short- and long-term work.”

Sewage systems
Sewer discharge piping is completely separate from site drainage systems. The sewer lateral should be cleaning once every five years. Mr. Devengenzo advises having a sewer system backflow unit installed outside your home to prevent sewage backup into toilets or bathtubs. With a backflow unit, the waste spills outside to prevent costly clean up inside.

DIAMOND CERTIFIED EXPERT CONTRIBUTOR ADVICE & TIPS FROM Robert Devengenzo

Expert CONTRIBUTOR PROFILE

Robert Devengenzo: Full Circle

By James Florence, Diamond Certified Resource Reporter

LAFAYETTE — After getting an early education in the construction field, Robert Devengenzo decided to switch gears and start a gardening business. However, as his business grew, he found himself incorporating more and more of his previous experience…until he eventually came full circle. “My dad built two or three of his own homes during his lifetime, and from the time I was 10 years old, he had me working alongside him,” he remembers. “After high school, I got into landscaping and ended up starting a gardening business with my wife, Marilyn. During the next few years, I acquired my landscape contractor’s license and brought on a few employees. It continued to grow from there—the more experience I had, the bigger the jobs became. It wasn’t long before I branched out from gardening and landscaping to doing drainage systems and general construction.”

Today, as owner of Devengenzo Landscaping and Engineering Inc., Robert continues to maintain a hands-on involvement with his company’s operations. “I enjoy meeting new clients, doing estimates and presenting our company to them. I also like to be out in the field, running crews and overseeing things. After all these years, those are still the aspects of the job I enjoy the most.”

Robert resides in Walnut Creek, which he considers an ideal location for someone in his line of work. “Between the affluent economy and the prevalence of older homes, there’s plenty of demand for our services in Contra Costa County. A lot of our work comes from homeowners who buy older homes and don’t know they have drainage issues. Also, with all the hills around here, there are a lot of challenges, which keeps things interesting.”

Outside of work, Robert enjoys spending time with his large family. “Marilyn and I have five kids, several of whom have worked for our business,” he says. “My oldest son worked for me for 12 years and is now a general engineering contractor, and my youngest is currently our lead carpenter. We also have 14 grandkids, ranging from age three to 25. Basically, there’s never a dull moment!”

In his life and career, Robert believes in doing things a certain way: the right way. “The main thing I believe, and the thing I impart to my employees, is if you’re going to do something, you have to do it right or not at all,” he affirms. “Other than my kids, I’ve had three guys who’ve worked for me in the past, and I schooled them well enough that they could get their licenses and be successful on their own. I take a lot of pride in that.”

When asked the first thing he’d do if he were to retire tomorrow, Robert says he’d transition to a more rural mode of life. “Marilyn and I did farming for about 14 years and enjoyed it very much, so I’d love to get back to doing that. We’d also like to do some more traveling—it’s been a long time since we’ve been out of the country.”

Ask Me Anything!

Q: If you could travel anywhere in the world, where would you go?
A: Italy, because that’s where my family heritage is based.

Q: What’s your favorite restaurant?
A: I have two: Il Fornaio and Fleming’s Prime Steakhouse & Wine Bar, both of which are in Walnut Creek.

Q: What’s your favorite holiday?
A: Christmas. In addition to my wife’s baking, I look forward to all the kids and grandkids coming over.

Q: If you could time travel, would you go to the past or the future?
A: The past. I love history, and I’ve always wanted to live in the Old West.

Q: Who’s your favorite movie cowboy?
A: Clint Eastwood.

  • Understanding Two-Pipe Drainage Systems

    LAFAYETTE — While often overlooked, drainage is nonetheless a vital functional aspect of any home. There are a few different ways to go about achieving proper drainage, but the most common method is installing a “two-pipe system.”

    A two-pipe drainage system is designed to pick up water at two levels: above and below the ground. The upper pipe picks up surface water from drain inlets, as well as water washed down from the roof, while the lower pipe is designated for collecting subterranean water. During installation, the lower pipe is wrapped in filter fabric to prevent silt intrusion and then filled around by rock to maximize drainage. Altogether, a two-pipe system ensures water is collected at multiple levels and transported away from the home to the proper outlets.

  • Video: Understanding your Drainage System

    Complete Video Transcription:

    LAFAYETTE — Host, Sarah Rutan: When having a new drainage system installed on your property, it’s worthwhile to get an idea of how it functions. Today we’re in Lafayette with Diamond Certified Expert Contributor Bob Devengenzo of Devengenzo Landscaping & General Engineering to learn more.

    Diamond Certified Expert Contributor, Robert Devengenzo: When we go to meet a client, our initial tip, most important tip is the fact that we’re going to put in a two-pipe system. The lower pipe is utilized to pick up subterranean water. The upper pipe is used to pick up roof water and to pick up surface water. And we think these are one of the most important things that clients should know about the functionality of a drainage system.
