Our business specializes in bathroom and kitchen remodeling since 2000. We offer a range of products where the customer is in charge of the design process. For our bathrooms we offer our beautiful Bella stone acrylic walls, walk-in tubs with no cutting of doorways (faster installation), and tile. For Kitchens we offer a range of options for cabinets, countertops, and backsplashes. Our business is family owned and operated. We have been in business for 21 years in the Raleigh and surrounding areas. Our father and son team have over 30 years experience in the renovations business. We strive to provide great customer service and love helping our customers visions become a reality.

"This company has some of the rudest and most disrespectful people working there. Veronica and Jessica should not be in customer facing positions. The bathroom remodel was done well, but the tile installer needs a bit more attention to details. We still do not have glass and had to call the glass company last week directly for an update as they were not being provided by New York Renovations. NY Reno kept stating there’s a delay and timing is estimated. However, Glass Depot told us the deposit was never paid and that was 7 weeks after they came out for a template. Just called the glass company again for the first time since early last week after continued vague updates from NY Reno. One very helpful person told me that NY Reno just paid the deposit via ACH earlier this week and that they’d call back after asking around for a timing update. Never heard back, so I called again but was told that NY Reno had instructed Glass Depot to not speak with me. The woman at Glass Depot specifically said she was told by NY Reno to not discuss any financial information but could confirm that “the glass has been ordered”. However, when I called last week, that same person at Glass Depot said the deposit was not made and glass had not been ordered. Meanwhile, for weeks, NY Reno was providing random updates about our glass saying they haven’t heard from the glass company, or that it’s just one more panel to come in. Those seem to be false as well as the “receipt” they emailed which was a text only document on Microsoft Word (not images). I’m sure NY Reno will reply to this and say they have gone above and beyond to make us happy. Or, try to put the blame on us and call us rude for following up directly with their vendor, but we have plenty of emails and an outrageous to show this. Plus, a bizarre phone call from Veronica where she berated me by saying that I picked the wrong person to mess with, calling me insane, etc. Update: After I left a review on Google, Veronica from NY Reno emailed stating that they will no longer be in contact or respond to any form of communication until there is a glass install date. She also continued the false line of allegations regarding harassment. Their response to this review, negative criticism, and a customer pushing for concrete updates speaks volumes."

Streamline Services, Inc. has been serving the plumbing, electrical and HVAC needs of Raleigh and surrounding areas for over 20 years. We offer 24/7 support and fast, same day repairs. We are a family-owned and operated business. We're committed to providing the highest quality service with our licensed and certified technicians, continuing training, and dedication to our community. Our core values are simple yet impact the way we go about our day – dependable, dedicated, positive, eager to learn, process-driven, and humble. The relationships we cultivate and develop amongst ourselves and with customers is something we pride ourselves with every day.

"I used Streamline Services to replace my HVAC system and to install insulation on the ductwork in my basement in August 2024, and unfortunately that was an extremely expensive mistake. We have since had them out 7 times that I have record of to repair issues related to the ductwork insulation, at extreme disruption to mine and my husband’s jobs which are based in our home, and on 2 of those occasions they also had a manager supervising. It’s the least of my concerns at this point but they left a mess each time they came, insulation scraps and screws all over the place and tape stuck to the floor. After all that, the insulation has never been properly adhered to the ductwork and has fallen down repeatedly, there are multiple areas all over our basement where the fiberglass insulation is exposed and where the tape has visibly lifted and the insulation is just resting on top of the duct. Their communication is somehow even worse than their workmanship. I’ve been trying to speak to a manager about a refund since December (I have record of 10 such inquiries I made in that time) and I’ve either been ignored or told that someone will call me and it never happens. They did give me a refund that amounted to roughly 8% of what I paid for the duct wrapping about two weeks ago, without contacting me or letting me know which I found odd, however that is not at all reflective of what I should be refunded after all of this and I think they just did it in hopes that I would leave them alone. I really wanted to resolve this with them amicably and have been exceedingly patient with them but unfortunately that goodwill hasn’t been reciprocated. We paid for our ducts to be wrapped and sealed and I think it’s clear we didn’t get what we paid for."

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.
