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.""

We promise accurate quotes that don’t change, and offer an on time service guarantee, with exceptional communication. Our company is committed to being as environmentally friendly as possible by utilizing multiple donation and recycling centers.
"Everything went very smoothly. Sam, the plumber, and is highly professional and knowledgeable. He replaced 3 faucets, 2 sink plugs, two valves, and two supply lines. Sam inspected the p traps, and he added adhesive where it was necessary. Sam also took a look at my two year old hot water heater, and he assessed my water supply to this unit. We discussed performing a complete drain, and check of the components of the heater at a later date. Sam also advised me that a toilet in the basement should be replaced with a more updated commode. We rarely use this toilet, but it's 35 years old. I felt comfortable speaking with Sam. I did not sense he was doing a sales pitch."

Their communication was very strong from beginning to finish, their initial plan recommendations were excellent, they made several recommendations to not only make the job better, but also make it more cost effective along the way.

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.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
The cost to finish a basement is $18,400 for the average homeowner. However, this cost could be as little as $2,800 or as much as $34,500, depending on the basement size and the materials needed. If your basement is already outfitted with electrical and plumbing, expect the cost to fall on the lower end.
For example, the drywall cost for this project averages around $1,750, but other features, like hiring a plumber, cost between $45 and $200 per hour.
The cost to remodel a basement is between $12,100 and $33,400 for the average homeowner. The price you pay can be as little as $3,500 or as much as $50,200, depending on the size and condition of your basement and the type of remodel you're doing.
If you're doing a simple project like adding a home office to your basement, you can expect to pay anywhere from $500 to $3,000. However, if you're adding a bathroom, which is an extensive project, you can expect to pay between $6,600 to $16,500.
Foundation repairs cost about $5,000, on average. Typically, prices range from $2,200 to $7,800, depending on the type and extent of repairs needed. Cost factors include foundation type, home size, soil stability, accessibility, and the ultimate cause of the problem and what methods and materials are required to fix it.
The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in.
If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
