We have locations in Algonquin, Arlington Heights, Elgin, Evanston, Hinsdale, McHenry, Naperville, and the Ravenswood neighborhood in Chicago.

"My regular plumber, that is great, Stephen's Plumb & Heat was busy so I tried Blanton and it really cost me. I needed several jobs - listed below with the Blanton quote. Replace toilet fill valve/flapper $624. Replace a garbage disposal $688.50. That's labor only as I had already purchased the new device. Replace a leaky Delta faucet cartridge $810. Clear a bath sink drain $350. Rod a tub drain $450. Grand total $2887.75! I declined and the Blanton plumber immediately dropped the price to $250 per drain. Still high but I chose to have lines rodded as he was already there. He started the plumbing work around 9:35am. He opens the sink pop-up and finds paper in the pop-up stopping the water and removes it. No rodding necessary. He does have to rod the tub. Both jobs are complete and I sign for payment 21 minutes later at 9:56am. He charged me $500. I realized the billing error, that I was charged for 2 roddings. I called the company to no avail. Invoices below. "

With over 27 years of experience, Modern View Kitchen & Bath Remodeling is Chicagoland's premiere General Remodeling Contractor. Your satisfaction is our only concern. Call us today. No job too small, we do it all.

"We've all heard those horror stories about bad contractors and botched remodels. Well, this isn't one of them. We decided to remodel our kitchen and bathrooms, so we researched reputable companies - using the popular home project review websites, Googling and combing through reviews, asking around, the usual. We made a list of about eight contractors and we met with six of them. There were two that we liked but Mark's ideas and attention to detail were better during the consultation, so we hired him to remodel our bathrooms. It's important to note that we made the first large payment with our credit card, really because we were afraid of hiring a contractor and having them disappear after we paid them. We were very cautious. After that first payment and spending some time with Mark and his crews, we were happy to write him checks when he asked because he had earned our trust. In fact, we had a punch list of some minor items after the jobs were completed, and Mark made sure everything was taken care of immediately, and this was after our final payment had already been made. His crews were on time every day and worked hard the whole time they were here. We liked the quality of their work and the materials they used so much, we had them stay and replace our basement floor. We then moved on to our other large project, our kitchen remodel. We trusted Mark and his crews so much that we gave them full access to our home while we were out on vacation. A pipe burst during that week, and one of Mark's men noticed it right away and fixed it immediately (Mark ran out to buy the needed plumbing supplies), preventing the basement from flooding and saving us quite a lot of money and frustration. We are first time remodelers, so we were asking questions and changing things throughout, yet Mark and his crews were incredibly patient, flexible, and professional. I can't recommend Mark and Modern View enough. We LOVE our sparkling new kitchen and bathrooms! A contractor who is honest, talented, professional, charges a very fair price, and is such a nice man. Hire him, you won't regret it. (In this day and age, you can expect a lot of fake reviews. We did not receive any compensation or discounts for writing this review.)"

"1. Very fast to respond to the the request 2. The staff was exceptionally nice, explained what they do and how they work. 3. Scheduled an appointment with a 2 hr window. 4. Repair showed up on time. (Two people) 5. They examined the problem and gave me a quote (fair and reasonable) 6. They went to work and resolved the sewer backup issue. Then they went ahead and cleared all the pipes of sludge until the water ran clear. They explained the issue was food residue buildup from the garbage disposal. That made sense since we has done a lot of summer and fall canning and used the disposal extensively. 6. They did a excellent job, very courteous and explained everything along the way. They used plastic to protect the surrounding area charged less than the estimate. 7. This is a family run business.

Tankless water heater installations FAQs

Yes, although they have a higher upfront cost compared to traditional units, tankless water heaters can be worth the investment for many homeowners. They heat water on demand, eliminating standby energy losses and leading to 24% to 34% greater energy efficiency for homes using up to 41 gallons of hot water daily. Tankless units last longer—around 20 years with proper maintenance—and require less space than traditional units. They also reduce the risk of leaks and water damage since there's no tank to corrode and fail.

Tankless water heaters, including gas-powered models, do require electricity to operate components like the ignition and control systems. This means they won't function during a power outage. If you live in an area prone to outages and want to ensure a continuous hot water supply, consider installing a battery backup system or generator to keep your tankless water heater running when the power goes out.

You should set your tankless water heater to 120 degrees Fahrenheit for optimal safety and efficiency, as recommended by the U.S. Consumer Product Safety Commission. Setting the temperature at 120 degrees prevents scalding accidents, particularly for children and the elderly, and reduces energy consumption. Temperatures above 140 degrees increase the risk of burns and promote mineral buildup, which can decrease the system's efficiency.

A 20-minute shower uses 50 to 60 gallons of water, assuming a flow rate of 2.5 to 3 gallons per minute. A typical whole-house tankless water heater can produce 4 to 8 gallons of hot water per minute, providing continuous hot water for long showers. By installing low-flow showerheads and reducing shower time, you decrease water consumption and energy costs, maximizing the efficiency of your tankless system.

With proper maintenance, a tankless water heater lasts around 20 years, significantly longer than conventional tank water heaters, which last between 8 and 12 years. Regular inspections and timely repairs can further extend its lifespan. To keep your tankless system operating efficiently, have it inspected or serviced annually and address any minor issues promptly by contacting a local tankless water heater repair service.
