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.

"They did an excellent job of waterproofing our foundation, burying downspouts, and replacing a patio to guarantee drainage away from the house. Most of our interaction was with the crew foreman. He spoke good English, showed attention to detail, and did a careful, professional job even when the weather got so hot we found ourselves urging the crew to take more breaks. They were not the cheapest bid, but worth it for the skilled workmanship. This is the second project we have hired them to do, and I would recommend them for any work where drainage is important."

"Tried to schedule a routine maintenance appointment available to customers who signed up for service plans, but Len could not follow through with their commitment three failed/rescheduled appointments in a row!! Each required four hour commitments from the customer. I tried to communicate with dispatch and customer service but unfortunately I don’t think these two departments have an open line of communication between them. I would not recommend for anyone to work with or engage with this company. Len did not follow through on their half of the commitment and disrespected my time as an in office working professional."

"Don’t use the plumbing! Called to have Kohler toilet tank plunger repaired. Whole installation is $20. Labor is an hour at $80 so the price is $150, at most. No, they charged $450–BS! These guys are a scam. No prices and I told them to have the repair person call me before arriving. No call, no prices. And, then the repair person has the stones to tell me that everyone overcharges!! Let’s start with not using Beacon!!!"

"I accidentally broke the PVC pipe leading out of the condensation drain coming out of my air conditioning unit. (This may seem to be a minor problem, but that is only because you didn't have to haul the buckets of water produced during this heat spell to the sump pump drain.) I put in the request on Monday afternoon. They arrived first thing Tuesday morning -- early. It took them all of about 15 minutes. I could not ask for better service. They were prompt, professional, friendly, and courteous."

Install Boiler questions, answered by experts

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

Boiler installations and replacements cost between $3,600 to $8,400. Expect to pay around $5,900 on average for a new boiler, including installation. Adding new radiators or heaters to the boiler may include separate costs if you are also upgrading those components, so the final price may be higher. To decrease costs, you can look for local energy rebates for using a boiler and wait until installers are offering discounts for a first-time installation.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).

HVAC systems last between 10 and 30 years, with an average life span of 20 years. However, the components of an HVAC system have different life expectancies. For example, a heat pump lasts between 10 and 20 years on average, while a furnace might last between 15 and 30 years.

By submitting this question, I acknowledge and agree that Angi may publicly display my name, city, state, and question on the website for professionals and others to see.
