"I had Oscar (owner) in the past but had never met him. My renters said he didn't respond to their calls when I need the original Septic repaired. First time I had him repair (rework) the newer septic. Then I found him again on Home Advisor - great!! He never received the tenant's call. He has 20 years experience. On time. Cleans up. Fast and efficient. Plus, he is a really a nice guy. He has an assistant Josh, also very nice guy. You won't be disappointed."

Customers say: True professional

"We decided to remodel our outdated bathroom, and McCormick Home Builders was a fantastic choice. Khaled and the team delivered high-quality work within the timeline and our budget. Every detail, from the tile work to the lighting, was beautifully done. They communicated well throughout, keeping us informed at every step, and the end result was truly a spa-like bathroom we can enjoy daily. We’d love to work with them again!"

"After getting a outrageous  quote from Mike Diamond for a drain to be cleared, we sent the not so smell good plumber packing and called Doc.Joe's. Sean and Bryant were on time, cleared our drain and then jetted the line to remove all the build up.
Doc Joe's cares so much about their customers, they take there time to explain the problem in detail and gave me choices. I felt no pressure. In fact before they started they provided me a detailed description on a iPad with the cost up front and a 1 Year Warranty. Very impressed with how clean they were, professional and courteous. 
I also asked them to give me a estimate on a water heater. While Sean was preparing the estimate his coworker performed a service on my water heater for free! I will definitely be using Doc Joe's Plumbing again!
Oh and one other thing, before they left, my invoice and estimate was emailed right away and I paid my bill on line. Very nice feature.
Thank You Doc Joe's! See you in November for the installation of my new tank less water heater.

"I called and setup an appointment for the afternoon.  The dispatcher called back in an hour saying the plumber was free earlier and came immediately.  He was there within an hour and gave me an estimate for the replacement and upgrade that I wanted.  I agreed to the price and within 3 hours I had a new water heater.  I can?t imagine where they could have done any better.

Septic Tanks FAQs, answered by experts

The dimensions of a 500-gallon concrete septic tank can vary from manufacturer to manufacturer, but the tank is large enough to handle the wastewater of a small home with up to one bedroom. Keep in mind that some states have a minimum septic tank size, and this often starts at 750 gallons. A 500-gallon septic tank may be too small to meet local regulations.

A mound septic system, when properly maintained, can last between 20 and 25 years on average—though some last longer or malfunction sooner than that. The most important part of maintenance is getting an annual inspection of the vital parts of the system to ensure they’re in proper working order and not too backed up with sewage.

The average three to four-bedroom home typically uses a well pump rated for 8 to 12 gallons per minute (GPM). To find the most accurate size for your specific needs, a common rule of thumb is to count the number of water fixtures and appliances in your home and aim for that number in GPM. This calculation allows for about one gallon of water per minute per fixture. Because estimating the correct size can be challenging, it's best to have a professional technician make the final determination. A professional can ensure your pump provides sufficient water for your home, especially during peak usage hours.

While abandoning a tank without treating it and following strict rules is illegal, there are several other ways to dispose of an old septic tank. One standard method is to pump out and crush the tank where it rests and bury it in the soil. Another is to remove it and transport it to a landfill. Finally, if abandonment is the best option, your contractor must pump out the tank and fill it with inert material, such as sand or concrete, depending on local regulations.

Concrete septic tank risers are heavier and more durable than plastic or fiberglass ones, making them suitable for long-term use. Installing a concrete riser differs from installing plastic or fiberglass risers primarily in the materials and methods used. The process involves cutting the concrete risers to the required length and then stacking them, using concrete sealant or adhesive between sections for secure attachment. Due to their weight, extra care is necessary during leveling and the attachment of sections. Concrete sealant or adhesive may also require a curing before the riser is ready for use.
