"Maplewood Plumbing was the 2nd company I called to replace a garbage disposal after the first company was blatantly trying to rip me off. The plumber they sent was on time, friendly, honest (he didn't try to upsell me models) and was less than a third the price of the 1st company I had called. Thankful for a company I can trust, I will absolutely use them again in the future!"

"Called today for a non-emergency service (no water leaks at the moment).  I scheduled an appointment for the following week.  A couple hours later they called and said they could come today.  Jason arrived a few minutes later.  He was very friendly and professional.  He reviewed the damage from the leak (we had turned off the water).  He was able to quickly determine the likely cause.  After making the fix he double checked to ensure the problem was fixed.  I really appreciated his expertise and ability to ensure the fix worked.  I also appreciated his friendly demeanor.
I have used Kirkwood Plumbing before and they will be the first for me to call.

"Had it not been for the installers Damien and Daniel this experience I would not have anyone go thru. It took 10 weeks of bare walls and plumbing pipes exposed in our master bath for a job that is nationally advertised in as little as one day. Had I not continually called (over 30 calls) trying to get information I would not have had ANY idea what was going on. Communication was nill! The installers were very professional and answered any and all questions I had. Thanks Damien and Daniel."

"I hired this company to extend the natural gas in my house and would definitely recommend them. I felt that the plumber who did the installation really knew what he was doing and seemed like a great guy. The installation went well and the price was fair."

"Very impressed with the professional appearance and demeanor of the installers. They initiated a series of pre install checks around the home that solved some issues and found a few problems that needed to be solved before they started. On top of going the extra mile, the install was successful and I'm a very satisfied customer. The manager was responsive and accommodating. Highly recommend Dunn One Hour Plumbing, Heating and Air Conditioning."

Plumbing FAQs, answered by experts

Common signs of gas line leaks include a rotten egg smell, hissing sounds, dead plants around the area of the leak, and unexplained physical symptoms like dizziness and nausea. If you notice any of these signs, act immediately. Shut off the gas supply to your home and call a pro to assess the situation.

The nice thing about outdoor water spigots is they last on average 10 to 20 years, depending on the model that you have. If you do happen to see any type of issue outside of that range, investigate the cause and what needs to be fixed to prevent further damage to your pipes or your home.

While some building codes allow galvanized pipe for natural gas, it shouldn’t be used for propane. Propane can cause the pipe to wear down, leading to dangerous leaks. Instead of galvanized piping for propane, you should consider coated copper, black iron, or corrugated stainless steel tubing (CSST). For underground propane line installation, you can use polyethylene (PE).

Watch for sinkholes in your yard. Also, if the water pressure in your sinks, showers, and other fixtures is notably lower, this is usually a sign that an underground water line is leaking. This affects sprinkler lines and can make the sprinklers shoot out water with very little water pressure, meaning they won’t water your lawn and garden as effectively as normal.

Depending on the location of the water leak, it could go undetected for weeks, months, or even years in some extreme cases. Most homeowners who have plumbing leaks have slow drips, so you might not see signs of damage until they become severe problems. It’s a good idea to have a plumbing inspection done annually and to take steps yourself to check for leaks, including inspecting your floor, walls, and ceilings for signs of water damage, monitoring your utility bills, and looking for water around appliances and fixtures.
