"Owner showed up with a small crew and a crazy new piece of equipment. Excavated down below my foundation and to the septic tank. Came into the basement and jackhammered the floor. Removed all the old terracotta pipe inside and out. Installed all new PVC pipe all the way down to the septic tank. Put gravel down to protect the new pipe. Poured concrete in the basement to close the floor back up. Only took one day to get the new pipe in. Came back the next to close the ground and floor up. Great experience, basement no longer smell like sewage."

"*PUBLIC BEWARE* If you have A-Affordable do work at your home you need to tell them if you do not want to have your property damaged. At least this is what I was told after the fact by the owners & their son that worked on my job. As far as I am aware the work that I hired them to perform was done well. The problem is that their heavy equipment mangled my asphalt driveway to the point where I had to hire an asphalt contractor to make repairs. My driveway was cracked & patched before they came but it was for the most part level, smooth and not a tripping hazard. Since completing their work the asphalt is ripped up, a severe tripping hazard and can no longer be plowed. I asked A Affordable to split the cost of the repair with me. Despite admitting the asphalt was damaged by them they were unwilling to do anything for me. I was repeatedly told if I had just told them I did not want my driveway damaged this would not have happened."

"After a bad winter with some issues with ice dams, decided we needed to get some gutter work and new downspouts and also had a chimney contractor no show so had to find another to do the work. Called a few places and had quotes from Old Dad Shook and another place. Old Dad Shook looked to have the better price and seemed to have better reviews so went with them. I had a busy summer so planned the work for fall and had gotten a call in June to start the work but let them know it could wait and I gave them a call in August and they were able to come out a couple weeks later to do the work. The day came and the first day, they worked on chimney pointing and capping the chimneys as well as painting and patching the box gutters. It was a pretty hot day so they spread the work over two days and the second day they took off the old downspouts and put on new downspouts. They did a nice job of attaching everything and setting them up. Unfortunately, we had an issue with the elbow on one of the downspouts on the ground that took some time to get taken care of and also had some leaking still around the chimney with a heavy rain that they came out and took a look at and sealed up the best they could"

"If you are looking for someone to do foundation work on your home or business, Engineered Foundation Solutions are the people to call! After contacting them through their website, I was contacted the next day to set an appointment for an estimate. They worked with my schedule and I met with Brian within 5 days.

After I sent my down payment and they put me on their schedule, Shannon their office manager contacted me every Friday to keep me updated that they were still coming on that date. Jeff their engineer, came to my house a week before work was to start to go over the work to be performed and answer my questions. Their work crew was very friendly and professional.

FAQs for septic system installation and replacement projects in Pittsburgh, PA

The smallest standard septic system uses a 500-gallon tank, which costs between $875 and $1,150 installed. This size works well for single-occupant dwellings with minimal wastewater production. However, many local regulations specify minimum tank sizes, so check with your building department before committing to this compact option. Some jurisdictions require at least 750 gallons regardless of home size to ensure adequate waste processing capacity.

The installation timeline varies based on site conditions, permit processing, and contractor schedules. The process includes obtaining permits, conducting soil tests, excavation, tank placement, leach field construction, and final connections. Weather conditions, soil challenges, and inspection scheduling can all affect the overall timeline. It's wise to begin planning well in advance of when you need the system operational.

The most economical approach is to install a conventional anaerobic system with a plastic tank. To minimize costs while maintaining legality, obtain multiple quotes from licensed installers, consider scheduling during their slower seasons, and handle basic site preparation yourself. Never skip permits or required testing to save money—illegal installations can result in significant fines and mandatory removal, ultimately costing far more than doing it right initially.

Regular pumping helps prevent system failures and extends operational life. Most small systems require pumping every three to five years, though frequency depends on household size and usage patterns. Pumping services cost between $290 and $530, making this maintenance expense relatively minor compared to potential repair costs ranging from $500 to $2,600 for neglected systems. Establishing a regular maintenance schedule based on your installer's recommendations helps avoid costly emergency services.
