Since 1985, Frank's Basement Systems has served the Greater Buffalo, Rochester, and Western New York regions in basement waterproofing, crawl space encapsulation and repair, and residential and commercial foundation repair services. As a member of several nationally-recognized contractor networks, such as Basement Systems, Supportworks, and CleanSpace, Frank's Basement Systems has access to patented, award-winning products and comprehensive training.

"Due to a rapid thawing, our home's sump pump started to fail and couldn't pump water faster than it was coming in from the drain tile. I came home from work to find a huge puddle of water in the area where the pump was situated, about 1/2" deep. The pump itself was working, but barely. After spending an hour bucketing water out of the pump well, I gave Frank's Basement Systems a call at around 7:45pm. One of their guys, Shane, was at my house within 20 minutes. He did a perimeter check outside the house and confirmed water was being pumped out, but the flow was minimal. He disconnected the pump from the piping, pulled it out, and I got a view of how corroded the old pump was, and it was chock full of debris and rocks. He cleaned the rocks from the pump and reinstalled to see if that would help the situation - it didn't. By this point, I was fully prepared to invest in a new pump, and he kindly provided me with the inventory he had available. Upon deciding which pump to go with, he went to his truck, drew up the paperwork that I signed, and he was able to install the new pump within half an hour. In addition to the pump, he redid the piping exiting the house and added a quiet check valve. Finally, he provided me with an estimate for a backup pump, at my request. Besides the great and thorough work, Shane was friendly, kind and honest. He did his due diligence in first attempting to repair the old sump before advising installation of a new model. He wore plastic booties over his shoes, wore a face mask the entire time and maintained proper social distancing. I've worked with Frank's at my previous house and am glad to have worked with them on the sump for my current house. I hope I won't need any work in the near future, but if I do, I'll continue to go with Frank's."

"It went terrible. I explained the water was backing up onto the first floor laundry room, the tech said he needs to snake at the main drain in the basement. Wellll...he uncapped my sewer line, broke the actual "y" pipe fitting on the main and spilled roughly 30-40 gallons on sewage onto my finished basement floor. Now my issue is not with the tech, he was polite, professional and accidents happen. My issue is with what happen next. Roto-Rooter said they would fix the pipe they broke(wow, thanks) but I would have to pay for them to clean up the mess($1,600.00) or they would just leave it there. I have 3 small children and the idea of sewage in my home potentially for days till i found another company to clean and disinfect was not an option. Now, my understanding is that Roto-Rooter is suppose to clean up after themselves, I did not break the pipe or have any sewage on my floors prior to their arrival, the entire mess was caused by their tech(again, a great guy). I just dont understand how I am charged for their mistake. To top it all off, they never snaked the line but kept the $600 line cleaning fee, guess to cover the costs of the pipe repair. On top of everything else, their clean up was not exactly the best. Pics included below, show the replace black fitting and yes, the brown on the wall and floors is sewage they never cleaned up. In summation, I am not suggesting to never use Roto, they are fast and mostly reliable. What i AM suggesting is that you ask 1.1 million questions prior to any work, because if there is a loop hole they will find it and use it to have you pay through your sewer pipe."

Water Heaters questions, answered by experts

According to the U.S. Department of Energy, tankless water heaters are anywhere from 8% to 34% more efficient than regular water heaters. Exactly how much energy you’ll save depends on your household’s water usage. When you purchase a tankless water heater, you’ll also likely upgrade to more efficient technology than your current water heater, which can add to energy savings.

Unusual noises, lack of hot water supply, efficiency loss, and visible leaks are signs of necessary replacement beyond mere repair.

Any item that can hold on to moisture and encourage mold growth should be discarded and replaced following water damage. Upholstered items, such as armchairs and couches, and soft items, such as mattresses, usually must be thrown away once they've taken on a lot of water. Soft furniture is difficult to dry out, creating an inviting environment for mold.

You may also need to replace hardwood furniture following water damage if you're unable to fully dry it out. If you have appliances and electronics that have been fully submerged in water, particularly sewage, you'll need to replace those, too.

Venting a gas water heater out of the roof is preferable in most cases. Heated exhaust gases naturally rise, so a vertical vent pipe is efficient. If you’re trying to vent through a pipe exiting a wall, the angle of the pipe may be more horizontal than vertical, making the venting system less effective. If you go through a wall, you may need to add a fan to ensure a successful expulsion of the gases outdoors.

The standard copper wire gauge to use with any 30-amp circuit is a 10-gauge wire. The National Electric Code specifies a 10-gauge wire with appliances like water heaters running on 30 amps. If you try to use a smaller gauge wire, such as a 12 gauge, with a 30-amp breaker, you run the risk of the wire overheating and melting or causing a fire. Because of the safety hazards, the gauge of the wire is not an area to try to cut costs when connecting a 30-amp breaker to a water heater.
