Super Service Award Winner for Last 4 Years in a Row! Celebrating 33 years as a carpenter on Cape Cod in 2017. I am experienced in all phases of carpentry. I am self employed and do the majority off the work myself. I have low over head and minimal subcontractors. This will assure you of a quality, cost effective project. I will be there to communicate with you “one on one” should there be any questions or concerns throughout the duration of the job. Additional website: http://capehomeremodel.com/.

"My family and I hired Jeff as our General Contractor to oversee the construction of our 1500 sq. ft. summer home. It was the best decision we made regarding this project. Jeff was a pleasure to work with. He was attentive to our design requests and of our vision for this home, while providing his expertise in all phases of construction from site work, foundation, framing, siding and roofing, stairs, and all interior finished work – including installing wood molding trim, doors, closets shelves, kitchen cabinets, bathroom vanities, all of which he does himself. Jeff hired and coordinated reputable subcontractors required to complete the project on schedule, and met all of his commitments regarding price, quality of materials, and high standard of professionalism and quality construction. Jeff was responsive over the 6-month schedule, keeping us informed of the overall progress, including subcontractor and weather delays, local permitting challenges, and coordination of several building inspections – all of which passed the first time attesting to the quality of Jeff’s work. Overall, whether it is a large or a small project, we wholeheartedly recommend Jeff for your construction project."

"We had this company build a new master-suite in our home. That included floor plan changes, tiling the bath, installing a new shower, a jetted tub and a new toilet. Only 3 months after many things fall apart. A glass shelf almost fell in the tub when my wife was in it. It almost injured her. Towel racks came of the walls leaving giant holes behind. The brand new tub stoped draining. I brought in a licensed plumber to fix that and he told me he never saw "such a sh*tshow". And conveniently Mike told me in the middle of he project that his company declared bankruptcy, so no point suing him."

FAQs for tankless water heater installation projects in Hyannis, MA

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.
