A robust infrastructure is the foundation of any successful home renovation. To help you understand the scope of these essential upgrades, we've organized our expertise into the following distinct Project Types. Each is a key component of a larger remodel or a necessary modernization for an older home.

Whole-House Plumbing Repipe (Water Lines): A complete replacement of aging and unreliable water supply lines with modern, durable materials like copper or PEX to improve water pressure and prevent catastrophic leaks.
Whole-House Electrical Rewiring: A comprehensive replacement of outdated and unsafe electrical wiring in older homes, bringing the entire system up to current safety codes and capacity standards.
Electrical Service Panel Upgrade & Replacement: Upgrading an outdated electrical panel to handle the demands of a modern kitchen, new additions, or the installation of solar panels and EV chargers.
Tankless or Tank Water Heater Installation: As part of a larger efficiency upgrade, we replace traditional tank water heaters with modern, on-demand tankless systems for endless hot water and energy savings. We also provide installation or replacement for traditional tank water heaters.
Main Water & Sewer Line Replacement/Repair: Addressing critical infrastructure issues by repairing or replacing the main water supply or sewer line that connects your home to municipal services.

And more, including EV Charger and Backup Generator Installation as part of a comprehensive electrical plan.

Our process integrates these system upgrades seamlessly into your larger remodeling project. Whether you're planning a major kitchen remodel that requires new dedicated circuits or updating an older home with a full PEX repipe, our team ensures your infrastructure is ready for the future.

"When should I consider a whole-house repipe instead of just fixing leaks?"
- If your home was built before 1980 and has galvanized steel pipes, or if you're experiencing recurring leaks, low water pressure, or discolored water, a full repipe is often the most cost-effective and permanent solution to prevent a future catastrophic failure.
"My lights flicker. Do I need a full rewire or just a panel upgrade?"
- Flickering lights can be a sign of an overloaded circuit or, more seriously, failing, outdated wiring. While a panel upgrade increases capacity, a whole-house rewire is often necessary in older homes to address the underlying safety issues of the wiring itself. We can assess your situation to determine the right course of action.
"I'm planning a major kitchen remodel. Will I need a new electrical panel?"
- It's highly likely. Modern kitchens with high-powered induction cooktops, double ovens, and numerous small appliances require multiple dedicated circuits. An older 100-amp panel often lacks the capacity, making a 200-amp panel upgrade a necessary part of the project.
"What's involved in replacing a main sewer line?"
- This is a significant undertaking that typically involves excavating a trench across your yard from your home to the street. We use modern techniques, including sometimes "trenchless" methods where possible, to minimize disruption to your landscaping and hardscaping.

Your journey to a safer, more capable, and future-ready home starts with a simple conversation. Let's begin the process of designing the robust plumbing and electrical systems your home deserves.
