I strive to design the clients vision aswell as provide renovation services of a luxurious kitchen and bath of their dreams. I pay attention to details and I work well with my clients to build their project scope of work. My focus is quality and professionalism!

"I was looking for a pro who was experienced, honest and could communicate to get the job done right. Dave was the man. He knew what I wanted and suggested options to give the project(complete kitchen and bath remodel) a 5 star review. After my rental was completely destroyed from a tenant, I was up a creek without a paddle. Dave and Pablo went above and beyond to create the Reno I was looking for. From the first interview to the end result, I have no reservations for recommending ModernKnight for any project. They were on time , completely transparent and accommodating every step of the way. Are you looking for the pro to get your job done? Look no further, Dave is the guy! Thanks again Dave and Pablo for everything and more! Freddy."

The price was very fair, best quote that I got. Gerardo made recommendations on what finishes to use which really helped me out. They finished the job quickly and left my house on top condition. I also gave them access to my house when I was not there and fully trusted them. I would def hire them again without hesitation. You won’t regret hiring Triangles !"

Tankless water heater installations FAQs

Professional flushing services for tankless water heaters run about $200 per visit. This essential maintenance procedure eliminates mineral deposits from critical components, particularly the heat exchanger. While homeowners can purchase DIY flushing kits for $50 to $100, professional service offers the advantage of thorough cleaning with proper techniques. Professional maintenance also includes inspection of additional components that might need attention.

Industry experts and manufacturers recommend annual maintenance for tankless water heaters, with more frequent service (every six months) for homes with challenging water conditions. This regular attention prevents efficiency losses and extends the unit's operational lifespan. Watch for warning signs like reduced water temperature, inconsistent performance, or system error codes that might indicate maintenance is needed sooner than scheduled.

Neglecting regular maintenance allows mineral scale to accumulate within your system, restricting water flow and reducing heating efficiency. This forces your unit to work harder, consuming more energy while delivering less satisfactory performance. Over time, this strain can lead to component failures, inconsistent water temperatures, and premature system replacement. Additionally, most manufacturers require documentation of regular maintenance to honor warranty coverage for major components.
