"Our 1920’s home is 3,100 square feet and required significant renovations to meet our modern lifestyle. My wife and I are in the design business [*** Link removed ***] so we’re very particular about the design and quality of the work to be preformed in our home. I have also renovated several homes, I’m pretty handy myself and have a fair amount of contracting knowledge. So I know what what to expect, how the work should be performed and the costs associated with it. We interviewed six highly rated contractors in a highly vetted and competitive bid process. Jeff set himself apart with his reviews on a number of highly reputable sites (including this one), home owner references (of which there are many) and team (plumbers, electricians, tilers, painters, finishing carpenters, plasterers, masons, suppliers, etc.). His team of subs all have been working together for over 20 years and take tremendous pride in their work. They’ll show you pictures of their work like the projects are their children. Best of all they all have worked together on so many projects that they complete each other’s sentences. So nothing gets lost in translation between the customer, contractor and sub. Jeff also has his own crew who are incredibly dedicated, skilled, hardworking (i.e. removed a two story brick chimney in 3 days) and polished. One notable member of his team is Elvis (and yes he's a rock star too). He is the go to person for any challenges faced during a project. He's highly knowledgable and skilled. And his easy going, "we can do that" attitude with a smile is always welcomed. Having spent months with him, my kids consider him their long lost uncle. The renovation included a complete gut of the kitchen, 2.5 baths and four bedrooms. We have completely updated the electrical, plumbing, windows, HVAC, furnace and hot water system. Added French Doors and skylights. We removed an obsolete two story brick furnace chimney which recaptured significant square footage. We have reconfigured and optimized most of the rooms and removed several load bearing walls to create an open floor plan. We refaced our fireplace in honed granite and replaced the fire brick. We're in the midst of finishing half our basement which will include a wood burning fireplace adding 610 square feet of living space. We also plan on renovating the attic into a living space with heating/cooling, new windows and skylights as part of phase two. Thus far there is no challenge we have thrown at Jeff that he hasn’t been able to address. He’s a consummate professional, honest, reasonable and the quality of work is outstanding. Further, the communication is excellent. He is always available (Saturday and Sunday if need be) and provides nearly daily updates with the progress of our project. I know I was thankful for the feedback I received from homeowners when making my contractor decision. I’m happy to do the same for someone else."

"Ayden was very kind and insightful. I was happy to meet an incredible worker like that from Long Home."

"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."
