"Install was on time and as described. '1st Response' did the job I expected for the water heater install. Good customer service for scheduling. Note that the Angie's list price of $799 only covers the installation of 50 gallon gas AO Smith hot water tank. Assuming you also do installation of new brass fittings, new flex lines and new expansion tank (which you should probably all do with the new water heater) it will cost an ADDITIONAL approx $500-600 (mostly labor costs). That's a competitive price but still, you should be aware that the original quote is just for the water tank install itself, nothing else. All-in-all they did a good job for a competitive price. A few months after the install, so far, I can say I would recommend them for this type of work."

"Plumber Quinn K. is first rate. He’s highly competent and happy to explain as he goes if you want. On time, pro install, cleaned up, too. Maybe more expensive than some other companies but worth it due to their responsiveness, professionalism and work warranties."

"Ron was very courteous and professional. He was very thorough and after unclogging my drain came back with three estimates for fixes. He tried to put a camera down my cleanout but couldn't get it open after trying for a while - he was trying to give me an estimate on how much longer I had left in my old cast iron pipes."

"French drain installation along a retaining wall (75 yards). Thomas who handled the sales end of things was friendly and responsive. The crew showed up on time. They were hard working and receptive of customer feedback. They first removed the ivy that was obstructing the work area and then completed the trench on day 1 which uncovered some of the unwelcome water sources. A legacy footing drain was plumbed directly into the main french drain pipe. Perpherated pipe was dropped in on Day 2 followed by river rock, catch basins, and 3 ft dry well installation. Cleanup was done thoroughly. I would hire them again in a heartbeat."

Drain Pipe Installation questions, answered by experts

Keep your egress window from flooding by ensuring that the drainage system in the window well is clear and in good working condition. Inspect the window well every few months to remove any blockages and test the drainage system. It’s better to discover potential problems before your window well fills with water during heavy rain.

You can unclog an AC drain line for free if you already have these household ingredients: water, vinegar, and rags. Alternatively, if you’d rather not deal with the mess, you can hire a pro to clear your drain line. If you go that route, an HVAC service call costs between $100 and $250.

Yes, continuing to flush a clogged toilet is not likely to break up the clog. Instead, it will continue to put pressure on the clog while filling the bowl with more water, which can potentially cause the toilet to overflow—leading to an even bigger mess. Rather than repeatedly flushing, use a toilet plunger or plumber’s snake to dislodge the clog.

You can try several easy methods to unclog a drain, one of the easiest and most effective of which is to use a mixture of baking soda and vinegar. This will help dislodge and dissolve the clog to move it down the drain pipes. Pour 1/2 cup baking soda into the drain, followed by 1/2 cup of white vinegar. Dump several cups of boiling water (or hot water if you have PVC pipes) into the drain and let sit for up to one hour. Run hot water to clear the drain.

Liquid drain cleaners are harsh chemicals that can erode your pipes. To treat a slow drain or for preventative maintenance, pour hot water down the drain to break up gunk and help move it along. Make sure the water isn’t boiling hot (keep it under 140 degrees Fahrenheit) if you have plastic pipes. However, you’ll need to pull the clog out for bigger backups.
