"I am genuinely flabbergasted that this company has so many five star reviews. From the marketing practices to their customer service, my frustration with them was pervasive. The work they did seemed to be fine enough, but it was overpriced (I later discovered) and their communication at several stages was just abysmal. My attempts to have them remedy the shortcomings of their process gained no satisfaction. It also left a really, really bad taste to discover that their signs plastered all over the furnaces and water heaters in the basement of our condo building was not because they had some kind of relationship with the condo *and in most cases had no relationship with the equipment that their signs were on*. Just obnoxious. To top it all off, someone my email address was leaked from their organization which led to it being the target of hacking. How would I know it was them? They were the only company that I had given that particular email address to, Then they had the nerve to ask for a customer testimonial video. As if. Would not do business with them again."

Fully Licensed and Insured In Business since 2006
"I hired Nilton and his company Pro Touch Construction to help completely demolish and renovate my 2BD 2BA 900 sq ft condo when I originally purchased it. The project included: - Complete demo of each room - Kitchen expansion and remodeling - Appliance installation (dishwasher, sink, stove, etc) - Complete remodeling of both bathrooms - Converting a stand up shower in one of the bathrooms to a walk-in shower - Brand new electrical and plumbing work (including installing in-wall speakers throughout the condo) - Install new vinyl flooring - Repainting the entire unit - Etc One of the things that stood out the most for me with Nilton is that he took the time to meet with me (several times) at the condo when I first purchased it. I had spent time designing each room with an interior designer using Pinterest photo albums and other inspiration I had found. But I also had a very fixed budget which not only did he make work but he consulted me on things I should consider to save costs (including going with vinyl flooring vs hardware floors). As shown in the photos, Nilton and his crew completed the project to absolute perfect. I was absolutely blown away with how beautiful my condo looked after he finished the job. And it's been 4 years and I still get compliments to this day from everyone who comes by to visit! Also, some of Nilton's suggestions (e.g. vinyl floors vs hardware floors), helped me save thousands of dollars in the long run. If you're looking for a skilled general contractor, who's very personable, honest and hard work — hiring Nilton and Pro Touch Construction yesterday. You will not be disappointed!"

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.
