"Mike was great. He took his time to explain what he was doing. I had a sediment filter installed and he replaced the pressure tank. He showed me how to check/replace filter as needed. He came by and diagnosed my problem without charging a service fee. He was very thorough and was not in a rush. His price was fair. He gave his professional opinion and did not try to "sell" me products that were not needed when I inquired about a water softener for my house. Great guys both him and his partner. I highly recommend giving them a call for your next plumbing job!"

"Gage is as professional as they come! He works efficiently, his rates are great and he left the site clean, clearing out any debris lying around. I am actually having him back today to do some other plumbing for me. When you find a professional that works above and beyond you keep them knowing that all your future jobs will be handled thoroughly and correctly. In my opinion Gage is 2nd to none. He is a keeper!"

"So far, so good. The finished project looks great; it really hasn't been tested yet as there has been little or no rain. Groundwater used to flow through the cellar after heavy rains so we'll see it the subsurface floor drain works. The floor looks good, the price was right (lowest of three bids) and Beth was very helpful and available to answer all my questions. At the moment, I'm very happy."

Im a military veteran looking to build my relationship with the community while building trust through my work. Ive worked with companies from corporate to local levels and have watched people get taking through loop holes for basic repairs by being offered the easy replacement option. I love learning new things about how houses were built and ways I can improve the living conditions for the homeowner. \n\nIve done work for affordable housing servicing hundreds of residents to helping customers with growing visions. Being upfront and being honest of all work and pricing is key to proper communication and building the relationship between customer and business. \n\nI strive to perform at a 5 star level and achieving your overall goal.

"The work itself, the actual basement waterproofing appears to be working but our flood season hasn't come yet so, I'm reserving judgement. But, the way the work was done was a problem and the initial way that they got with the problem wasn't satisfactory. Eventually, months after work I did get some resolution but is wasn't a smooth transaction. We moved some of the finished portions of the basement to do their work and the way that that was handled was very sloppy and rushed, and very expensive to repair. And then, when the initial point of having somebody come and look at all my questions, it was not the owner, it was his foreman and it was not dealt within a professional manner. After 2 contacts, tried to explain what the problems were and has offered that they have an annual service to make sure that everything is working and there's a fee for that, though he offered 2 years of that with no cost, so that was a nice gesture. He tried to make up for the problems but like I said, there were problems."

"I called Gregg and he came out to survey the situation within a couple of days. He was hopeful that he might be able to bring the bathroom up to code without ripping out all the fixtures, but couldn't say for sure without actually cutting a hole in the wall in the room next door. About three days later he called to ask if his associate Donny could come out and take a look. I thought he was just going to cut the hole and then let Gregg make a final decision. Instead, Donny got the job done by mid afternoon. Not only that, he didn't leave a speck of dust even though he had to jackhammer into the foundation.
I am very pleased with the result and the price, to say nothing of the speed with which the job got done. I think it was less than two weeks from the initial call to finalizing the work.

Drain Pipe Installation FAQs, answered by experts

Never pour used motor oil down the drain. Doing so can have serious environmental consequences, including contaminating groundwater, endangering animals, and killing vegetation. It can also clog your pipes, causing backups in your plumbing or the wastewater treatment plant. In most places, pouring motor oil down the drain is illegal, whether you do it in your home or a storm drain.

Your sewer line can get grimy quickly. To prevent sludge buildup in your sewer line, pour a mixture of 1/3 cup of vinegar and 1/3 cup of baking soda down each drain in your home once a month. After about 30 minutes, flush the drain with hot water.

Some plumbers recommend 3/4 cup of bleach instead to clean any germs and bacteria that may build up in your sewer line. But this won’t break down any active clogs, and it cannot be combined with vinegar, as the mixture will create a toxic, hazardous gas.

Snakes can occasionally enter homes through shower drains, although it’s quite rare. This can happen when they follow sewer pipes or accidentally find their way into plumbing systems. To minimize the risk, consider installing drain covers or stoppers on your shower drains. Always keep drains closed when they’re not in use, especially in areas where snakes are known to be active.

You may have a clogged gutter. Downspouts can also clog if your gutter collects too much debris. Hire a professional gutter cleaner, and if you still have problems, install a gutter guard (which prevents debris from entering your gutter system) and a downspout extension (which helps drain water further away from your foundation, so it doesn't pool near your house). Follow these tips to keep your gutter downspouts clean.

This depends on the location of the blockage. If the blockage is in your home’s system, anywhere in the system, it is your responsibility as a homeowner. Blockages seldom happen because of items or buildup coming from the city, which means it originates in the home. It becomes the city’s responsibility at the exact point your home’s line distributes waste into the city’s system. The exception is if the problem in your home damages the city lines.
