Drainage & Erosion Solutions (DES) is an award-winning design-build firm specializing in diagnosing and resolving drainage and erosion issues for residential and commercial properties. 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. All consultations, assessments, and installations are performed by licensed experts—including soils engineers and landscape and drainage system designers—who bring decades of combined experience in design and construction. 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.""

"Willis Builders did 2 full baths & kitchen reno + laminate floor install on main level of our modest 3-story T/H (Jan-Apr ‘24). Marcelo was our PM and as many others say, his crew did not disappoint. Willis was neither the highest nor the lowest quote of several but we felt Matt Willis presented the most honest and realistic estimate for our project and he hit that nail on the head. They might say we bothered them with questions; we might say we had to nudge them a few times. We did our homework to help things move along more smoothly & they did their best to accommodate us. We purchased a bunch of stuff before choosing a contractor. No matter what we threw at them, installation was a success which is a testament to the knowledge and capabilities of Marcelo & crew (Horatio, Frankie & “George”). When we were undecided or unsure about a product, Marcelo steered us toward better or more appropriate alternatives. We had no issue, as a few others suggested, with crews leaving things clean at the end of the day. Our T/H is small with limited space for them to work/store materials & equipment. We never felt compromised during 3 months of disruption. (And we never hesitated to leave our home when work was being done.) Is everything perfect? No, there is no such thing as perfection in an almost 40-yr old house reno or any reno for that matter. There were a few glitches as we expected, but uh-ohs and problems that arose were resolved promptly. We waited to post this glowing review of our project to see if any problems showed up, and none did. Until the ceiling in our bedroom collapsed several months later which had absolutely nothing to do with their work. We are so thankful that we had no reservations about sending Matt Willis an SOS for help with our emergency. In fact, we were so confident in his work that we decided to add painting and a carpet upgrade to what has become an almost total house reno. Again, Matt’s estimates were fair and reasonable, such that our confidence in his company allowed us to forgo spending time getting quotes from others. Matt told us repeatedly how good his ‘drywall guy’ was, and he did not exaggerate! Will & sidekick Carlos were fast and fastidious! The carpet install was equally quick and painless. We are so very happy with the results of our sudden and unexpected 2nd Willis project. We're sorry we didn’t get a chance to rave about how thrilled we are with the results of our 1st until now. If you’re considering home improvements, we highly recommend you consider Willis Builders. We’re doubly happy we did!"

Fire sprinkler services FAQs
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.
If you find evidence of water damage in your home, your best option is to call a local water damage restoration company immediately. You could call a plumber first if you know that the issue is stemming from a plumbing pipe, but in many cases, a company that specifically handles water damage will be able to find the source of the damage and recommend a specific repair. Water damage restoration pros will also be able to develop a plan to remove any damaged material and restore your home to its previous condition.
The average water damage restoration cost is around $3,500, but it’s not uncommon to see prices fall between $450 and $15,000. Your project cost will depend on the extent of the damage, the source of the water, whether or not mold has grown in the affected area from the moisture, and the emergency level of your water problem. Keep in mind that your insurance company may cover some or all of your restoration expenses if your homeowner’s insurance policy covers the specific issue.
