"There is nothing worse than a plumbing problem as we don't often need a plumber's assistance. When you wake in the morning to water in your basement it is a panic. We were luck to be contacted by Steve Ricci and he said, "I will be there by 3 PM", and he was 15 minutes early. I showed him the leak and he quickly determined what could be done, and what were the options. He then went to a plumbing supply house to get the parts and return. Steve returned and di the job in a bit over an hour. He explained what he did, and how to prevent it in the future. We were very pleased with entire experience and the cost was not exorbitate. Two thumbs up for Steve, and we would use him again."

"Three terms you don't hear when speaking about contractors : Honesty, timely and effecient and pride of Workmanship. If you use Liam Neary Construction you will be using these terms and smiling as you tell others about your amazing experience. I had a leak in my roof with water coming in through the chimney. The water came into the utilitiy room creating a mini swimming pool and the hot water tank shut down. Liam came out within an hour of my phone call got my water running showed me how to clean the sensor for the future and reset the hot water tank. He scheduled to come out later that day to replace flashing on the roof to hopefully fix the problem. Unfortunately for me, it was not the full resolution. In the next rainstorm, I got water in the chimney again and reached out to Liam. This time it was a saturday and was thinking I might see him at the start of the work week or need to pay crazy money just to get him to show up. This was not my experience he showed up in 2 hours reviewed what he had done and come up with a new solution. He determined that the chimney needed some additional work and adjusted the price because of the original work that he had done correctly, but did not solve the problem completely. This contractor is the real deal. If you have a problem give him a call today. He will make your life easier and resolve your problems quickly. For the job done right call Liam Neary."

"The plumber arrived during the timeframe that he committed to and was very professional. He reconnected our gas stove and the price for the job was right within the estimated quote. I would recommend KMD to anyone on Cape Cod who is in need of a good, reliable plumber."

"I thought the price for a sump pump replacement was very expensive for what I had done (2 men, 2hrs). They quoted the estimate and charged me $1,500.00. Home Advisor had emailed/quoted me a fixed price of approx. 600.00. I had asked to schedule when they could do the job and said they could do it that day, THIS WAS NOT A RUSH/EMERGENCY, but I gave the go ahead because I just wanted this project done. There was no drilling involved (in the well and the wall to drain out). They replaced the sump pump and installed a new drain pipe in the well and attached it to the existing drain in my cellar wall. The plumbers were courteous and explained everything thouroughly so that weighed in on my overall star rating. Thanks."

Affordable Plumbers FAQs, answered by experts

The age of your MA home dictates the scope of your plumbing project, as older cottages feature outdated piping or lead solder. Identify whether you rely on a municipal sewer or a private septic system, and review your latest inspection records. Note your foundation type, since unheated crawl spaces create severe freeze risks. Finally, confirm whether your property sits in a flood zone to determine below-grade requirements.

Helpful?

Always hire a licensed professional for plumbing in Dennis, and ensure they take responsibility for pulling all required permits. Look for contractors with specific experience handling seasonal property winterization and private septic systems, as these are common local requirements. Because summer brings high competition for contractors, schedule your projects early. A knowledgeable local expert will also understand the unique water pressure characteristics of your specific district.

Helpful?

Routine plumbing maintenance in Dennis includes annual winterization for seasonal properties to prevent severe freeze damage. Year-round homes require heat tape and insulation for pipes in unheated crawl spaces. Schedule regular septic pumping every three to five years to maintain system health. Inspect exposed metal components annually for salt air corrosion, and always maintain your water treatment equipment to handle the unique chemistry of the local aquifer.

Helpful?

Thorough plumbing work in MA includes a completed inspection sign-off from the local building department. A licensed professional will always pull the required permits and ensure the installation passes state-mandated pressure tests. For seasonal homes, correct work features properly sloped drain lines and accessible shutoffs for easy winterization. Additionally, any new fixtures must safely align with the capacity of your private septic system.

Helpful?

For plumbing in Dennis, materials must withstand coastal salt air and humidity, which accelerate metal corrosion. The local groundwater is slightly acidic and low in minerals, making certain copper pipes vulnerable over time. Choose durable, code-compliant materials that can handle freezing temperatures in uninsulated crawl spaces. For seasonal properties, select components that allow for repeated winterization and re-activation to keep the system secure year after year.
