With both engineering and contracting divisions, we deliver professionally engineered solutions that are as functional as they are aesthetically pleasing. Our team is composed of dedicated, full-time professionals known for their technical expertise, attention to detail, and commitment to exceptional customer service.

Clients trust DES for our reliability and results, leading to a strong referral-based business and consistently high rankings on contractor-rating platforms.
""After 15 years of enduring water and flooding damage to our yard and the foundation of our house, and after trying various 'solutions' from well-intentioned landscapers that never truly resolved the issues, we ultimately decided to engage Drainage and Erosion Solutions. We required comprehensive flood control and damage mitigation, and their expert team skillfully implemented swales, dry creeks, catch basins, and channel drains in areas where water management was critical. They also replaced a water-damaged window well, removed a flagstone patio to install drain basins and drainage pipes, and flawlessly reinstalled it. The supervisor and crew displayed remarkable knowledge, professionalism, and an unwavering commitment to detail throughout the entire project. This system has been operational for several months now, and even during the most intense rainfall, which historically led to road flooding, my house and foundation remain dry. We enthusiastically endorse this company without reservation.""

"Summary: I hired Hydro-Tech to install a new Hunter sprinkler controller with a wireless rain sensor, and replace a broken sprinkler head. Communication has been poor throughout, including scheduling. I had issues with the controller immediately after installation. While I contacted the tech who provided the proposal via email the same day as the install occurred (5/25), it's been 11 days since I sent that email and I have received absolutely zero response. Given that I reported the controller as defective within a few hours of the installation and have received no response, I can only assume that Hydro-Tech cannot be trusted for after-installation support in any way. Caution is strongly advised. Full description: I requested a quote to install a new sprinkler controller a replace a broken sprinkler head. I was able to get David Ogurko to come out to provide a quote the next day. He indicated it was a small job and probably wouldn't take more than 1 hour of labor. He said the work could be scheduled relatively quickly. David provided a reasonable quote. The proposal requested 100% payment upfront but I emailed him on May 2nd to request 50% payment in advance, 50% upon completion. Given the small size of the contract, he said I could just pay the entire amount upon completion. I then returned the signed contract on May 3rd. David emailed me on May 4th stating that I would hear back shortly regarding scheduling. As I heard nothing by May 11th, I reached out for information. He responded saying he couldn't schedule the work because he hadn't received payment - even though he previously said I could pay after the work was completed. I forwarded the prior email and he responded, "I will take care of this first thing in the morning." One week later on May 18th, I received an email stating that the work would be completed on the 25th, between 7 and 12 PM. A tech arrived shortly after 7 AM. He installed the controller, replaced the damaged sprinkler head, and physically installed the rain sensor. However, he never setup the rain sensor on the controller. I only discovered this after he left, and I had to call to have it done remotely. I immediately began having issues with the controller. Despite installing a wifi access point in close proximity to the sprinkler controller, and the controller and my Ubiquiti controller reporting a very strong signal, the sprinkler controller would drop off the Wifi approximately 30 minutes after initial setup. Rebooting the device resolved the issue temporarily until it occurred again. I sent an email to David the evening after installation (5/25). It is now Monday, June 5th and I have yet to receive any response from David. I later discovered that the Hunter controller just has very poorly designed Wifi code. Wireless devices are expected to connect to the strongest access point when multiple access points broadcast the same SSID (wifi network). This allows you to seamlessly roam between access points in a large building/home, and works well with most laptops, smartphones, tablets etc.. However, it appears the Hunter controller would connect to the proper access point, and for no apparent reason, drop the connection if it saw other access points broadcasting the same network. When I created a dedicated wireless network for the sprinkler controller only on the access point with the best signal, the issue went away. While I appreciate that it now appears to be working, the fact that I received no response whatsoever from Hydro-Tech indicates that they cannot be trusted to provide any after-install customer service."

"Needed to replace a 25+ year old HVAC system in the coldest months of the year, so I contacted Advanced Environment Solutions for a bid. I worked with Tammy at AES to schedule the inspection, follow-up, etc. - a fantastic employee. Courteous, professional, and really knows her stuff when it comes to HVAC. Unfortunately, I live in a condo with a tricky indoor/outdoor HVAC set-up that ended up requiring a fairly specific indoor unit that AES did not offer, so I had to go with another company. Still I felt compelled to leave a review for AES and Tammy to highlight their professionalism and service-oriented approach. WiIll absolutely consider AES for future projects."

Landscapers typically charge $25 to $50 per person per hour, which equals around $50 to $100 per hour for a two-person crew. These rates can vary depending on your location, the size of staff needed for the job, and overall job type. For example, a larger crew will be needed for structural additions and hardscaping versus planting flowers.
When it comes to landscapers, licensing laws vary. Landscaping architects are required to be licensed in all 50 states, whereas traditional landscaping contractors are not typically required to hold a certification. You’ll likely be working with a landscaping contractor for most residential projects. If you are redesigning your whole yard or adding in hardscape features, you will work with a landscaping architect at some point during the project. Be sure to check our state licensing tool to review the local landscaper guidelines.

Yes, most states require plumbers to be licensed, and for good reason. Hiring an unlicensed plumber could lead to poor quality work, costly future expenses, and potential code violations.

We highly recommend leaving the work of replacing drain pipes to a professional plumber. Drain pipes are a key part of your plumbing system, and making mistakes during the installation or even using the wrong size pipes for your specific fixture can lead to an elevated risk of leaks and clogs. Additionally, drain pipes prevent harmful sewer gas from entering your home, so hiring a professional plumber is essential to keeping the risk of leaks and clogs low and avoid reducing your indoor air quality.
The cost to install a drain pipe is $600 on average, but the total can range between $150 and $2,000. Some cost factors that influence your project price include the type of drain, the area’s accessibility, the proximity of existing drain lines, and whether you’re installing a new drain or replacing an old one. Replacing the p-trap or s-trap under a single fixture will usually cost around $150, while replacing a main drain pipe can cost well over $2,000.
