We service residential and commercial needs. Whether you have a major remodel, home addition, minor home repairs, or anything in between we can help. We are a master plumbing and gas fitter as well. Quality, professionalism, and workmanship are the foundation of our business. Our biggest priority is our customers satisfaction. We provide competitive pricing without a lack of quality or professionalism. We are built on the premise that without our customers we wouldn't be here.

"Our deck caught fire last summer and we contracted Chris Heinz to do the rebuilding and replacement of our fire-damaged exterior. Chris was wonderful to work with! He worked with our insurance company tirelessly and also kept us informed every step of the way. He and his crew removed our old deck and siding, and built a new deck, a landing and stairs off our kitchen, installed a new sliding door and four windows, replaced our siding and trim, and installed new outdoor lighting. There were a few delays due to the pandemic and materials being readily unavailable from one of the manufacturers, but the timeframe was reasonable given the circumstances. Chris and his crew did an amazing job and we couldn’t be happier. We love our beautiful new deck and the new siding and trim. We get so many compliments from our neighbors and passers-by! We will definitely go to Chris next time we need work on our house and recommend him to everyone!"

FAQs for percolation testing projects in Potomac, MD

The average cost to snake your main sewer line is around $250 for a simple snake. Most sewer line specialists charge between $45 and $200 per hour for main sewer line snaking, so the time involved plays a major role. The price you’ll pay will depend on the severity of the clog, the item causing the backup, how long it takes to remove the item, and more. A more severe issue that requires unclogging a main sewer line will cost $3,100 on average.

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 of septic tank repair is $1,775 for the average homeowner. However, depending on a few elements, you might pay as little as $170 or as much as $6,100. Location, repair type, and tank material all determine the final cost. For example, replacing the septic tank filter can be as little as $200 to $300. However, repairing septic lines costs more, averaging around $1,500.

The average cost to unclog a drain is around $200, with prices ranging between $110 and $800, depending on the type of drain and the extent of the clog. Hiring a professional to snake the toilet or sink will usually cost between $110 and $275, a bathtub or shower typically costs around $225, and a main line clog can cost between $100 and $800 based on the severity of the clog and how far beyond the access point the clog sits. Since the labor involved varies, most plumbers will charge an hourly rate for drain cleaning.
