Merrimack Valley Plumbing, LLC is a locally-owned and operated company committed to providing fast, affordable, and high-quality Plumbing. We offer HVAC repair, installation, and replacement services. We specialize in heating controls and simplifying complicated plumbing and HVAC systems to make them user-friendly. We strive to find solutions that fit everyone’s comfort needs, from construction projects to air conditioner replacement.

"I hired Merrimack Valley Plumbing to install a boiler in my home, and my experience was overwhelmingly disappointing. While the boiler functions, the installation process and quality of work raised numerous red flags. I want to share my experience to help others make an informed decision when considering this company. Installation Issues Code Violations: The exhaust is less than 3 feet from the gas meter, and the holes drilled in the joists for intake and exhaust are less than 2 inches from the bottom, both of which do not meet code requirements. Improper Venting: Both the exhaust and intake vents are installed too close to the ground (not meeting the 12-inch clearance required for expected snowfall) and are too close to each other (less than the 12-inch separation required). Unsealed Penetration: The hole drilled in the siding was left unsealed, creating a potential entry point for rodents. Condensate Drain Issues: The installed condensate pump is leaking and wasn’t tested. Additionally, rather than a permanent drain installation, they daisy-chained it into a pump for a portable air conditioner. Wiring Errors: The zones for the primary bedroom and second floor were wired backward, causing overheating in both areas. Missing Outdoor Sensor: The outdoor temperature sensor, critical for proper operation, was not installed. No CO Alarm: A carbon monoxide alarm was not installed, which is essential for safety. Unprofessional Workmanship: Trash, including a metal duct pipe, was left in the crawl space near live electrical wires. Process Concerns Permit Delays: The company failed to file permits before starting work. I only discovered this after contacting the town permitting office myself. Mismanagement and Delays: The project stretched far beyond the promised timeline, with repeated excuses about missing parts and limited crew availability, despite prior assurances that the job would be completed in two days. Broken Promises: They claimed a project manager would take measurements in advance to ensure a smooth installation, but no one came. Additionally, they rescheduled initially, promising a larger crew, only to send a single plumber on the first day. Misinformation and Deception Throughout the project, I encountered multiple instances where Merrimack Valley Plumbing provided misleading or false information: - They lied about the dates permits were filed. - They claimed delivery issues caused delays, though they should have anticipated these based on the advance photos provided. - They repeatedly shifted blame rather than taking accountability for the delays and issues. Overall Experience While the boiler itself works, the installation was riddled with code violations, safety oversights, and poor workmanship. Additionally, the company’s lack of transparency and repeated dishonesty made an already frustrating situation worse. I would not recommend Merrimack Valley Plumbing to others. Their lack of professionalism, disregard for safety codes, and failure to take responsibility for their mistakes created an unnecessarily stressful and costly experience."

FAQs for gas leak repair projects in Concord, MA

Yes, most states require a plumber to be licensed, and for good reason. Hiring an unlicensed plumber could lead to poor quality work, costly future expenses, and potential code violations. Check our state licensing tool to review the local plumber guidelines.

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification, which include:

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.

Fixing a gas leak costs about $45 to $150 per hour for a plumber or gas line specialist. The job’s overall cost will vary depending on the location of the leak. A leaky junction or connection behind the stove or dryer will likely cost about $120 to $170. But for a leak that requires a gas fitter or plumber to excavate a pipe in the yard, the cost could rise to $1,500 to $5,000. Keep in mind that gas leaks are very serious issues, so don’t hesitate to contact a plumber or gas line specialist immediately.

Fixing a gas leak can take anywhere from one to 24 hours, depending on the location and magnitude of the problem. A gas line specialist or gas plumber should be able to give you an estimated time to completion once they evaluate the situation. If your city’s utility company works to fix a gas leak, it will likely have information available about the anticipated time for gas service to be restored. 

The cost of repairing a gas leak depends on the type of leak, its severity, and how difficult it is for the repair technician to reach it. Some of the most common gas line repair costs, on average, include:

  • Cap a gas line: $75–$150

  • Gas system inspection: $150

  • Pressure test: $75–$500

  • Damaged or corroded pipe: $6–$7 per linear foot

  • Repair gas leak: $120–$5,000

A local natural gas plumber, gas fitter, or gas line specialist should fix gas leaks. Installing gas lines and connections improperly can lead to dangerous gas leaks and explosions. Only a certified plumber or gas line specialist should run gas lines. This is not a job to try out DIY skills, so hire a professional gas plumber or gas line specialist immediately to find the cause of the leak and fix it quickly.
