"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."

About Us: We are locally owned/operated professionals providing dependable service. Able Well & Pump Service (AWPS) (formerly Artesian Well & Pump Service) has A Cell Number Also At 410 458 7171
"Able Well helped me perform a chemical treatment of my home well after it failed a bacteria test. They also replaced and rewired the well cap. They were knowledgeable about the system and taught me a lot of great info about my home system. The reason for 1-star is the complete lack of punctuality. They were 5 hours late on the first day and 4 hours late on the second date. No one ever reached out to me to let me know they would be late or communicated a need to change the time of the appointment. For how expensive the service was, I would expect better communication and ability to keep an appointment. I'd recommend shocking your well yourself, it isn't hard, and spending almost 10 hours waiting on arrival was a hard way to spend my day."

"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."

FAQs for septic tank service projects in Monrovia, MD
Yes, most states require septic tank installers to have a license, and for good reason. Hiring an unlicensed septic tank pro 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 replace a septic tank is $7,350 for the average homeowner. This cost can range, however, from $470 to $22,500, depending on several factors. Your house size is a significant factor in the overall cost, but other things like material type impact the final price tag. For example, installing a new septic tank in a one-bedroom house typically costs $500 to $900, whereas installing a new septic tank in a five or six-bedroom home is generally $1,200 to $1,600.
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.
A septic tank can typically last 15 to 20 years on average, though your system's lifespan will vary depending on the type of septic system and the materials used. To help increase your septic tank's lifespan, schedule routine maintenance and do not flush items like cat litter, cigarette butts, or paper towels.
Repairing or replacing a septic tank is a job best left to a professional. Your septic tank is an essential part of your home, and if installed or repaired incorrectly, it could lead to significant problems. Things like polluted water, property damage, and health risks to your family could all happen as a result of an improper septic tank repair or installation.
