We offer elegant and practical building and remodeling solutions for your Cape Cod home, tailored to your taste and needs. IHS is a fully licensed/insured, family-owned company, with over 20 years of experience in all phases of residential construction. We focus on building lasting professional relationships with our customers, and becoming their trusted go-to contractor for all of their home improvement needs.

"We recently had an “old school” original 1970’s Cape Cod kitchen fully remodeled including adding a slider. Richard did a great job from planning and design (shout out to Hanna on this), to demo, to install, to finish work. Richard was on time, reliable, and not your typical Cape contractor. Super clean at all times and was able to work with us on various hiccups/unexpected stuff along the way. He explained options and the pros and cons of each possible choice. He never upcharged us (unless we asked for something) and was exactly on budget. Very happy with his work and would definitely recommend. We will likely call on him again for our next project."

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.
