Nationwide Plumbers is a NYC Licensed Master Plumber, License #2023, serving Hollis since 1984. We dispatch 24/7 and handle sump pumps, sewer lines, boilers, water heaters, gas lines and leak repair for one- and two-family homes. Call 718-748-2727.
Hollis is a residential neighborhood of detached and semi-detached frame and brick houses, many built between the 1920s and 1940s, on blocks running off Hollis Avenue, Jamaica Avenue and Farmers Boulevard. The LIRR stops at Hollis station near 193rd Street, and Holliswood rises to the north. Most homes have driveways, front and back yards and full basements, and a good number have been converted to two-family use over the years.

Two plumbing concerns come up here again and again. The first is water in the basement: parts of southeast Queens have high groundwater, and Hollis basements can stay damp or take on water. The second is age: original sewer lines, boilers and water heaters that are reaching the end of their service life. We handle both with 24/7 dispatch, written estimates and a 1-year labor warranty.

Common plumbing issues in Hollis
Groundwater in Hollis basements
Groundwater levels have risen in parts of southeast Queens since the old local supply wells stopped pumping, and some Hollis homes see seepage through the floor or walls even in dry weather. A sump pit with a reliable pump, a check valve and a discharge line that carries water away from the house is the standard plumbing answer. We install and service these systems and add high-water alarms.
Aging boilers and water heaters
Many houses here still run boilers and water heaters that are well past their expected life. A rusted tank bottom, a boiler that leaks at the sections or a burner that keeps locking out are signs replacement is close. Damp basements also shorten equipment life. We give free estimates and size new equipment to the house.
Original sewer lines to the street
Houses from the 1920s to 1940s often still have clay or cast iron sewers running under the front yard. Roots, shifting soil and age cause cracks and recurring clogs. We camera the line to show you its condition before quoting, and we offer financing through Wisetack for replacements.

Plumbing in Hollis: FAQ
My sump pump runs all the time. Is that normal?
In homes with high groundwater, a sump pump may run often, especially in wet seasons. If it runs with no water coming in, the float may be stuck or the check valve may be failing and letting water flow back. We can check the pump, valve and discharge line and replace parts as needed.
How do I know if my basement water is from the sewer or groundwater?
Sewer backups come up through floor drains, toilets or tubs and usually have an odor. Groundwater seeps through the slab or walls and is clear. The fixes differ: a backwater valve or sewer repair for the first, a sump pump for the second. We inspect and tell you which you have.
Do you replace water heaters in Hollis the same day?
Often, yes, when the replacement is a similar size and venting type. We give a written price before starting and haul away the old unit. Learn more on our water heater page.
Can you look at a gas smell near my boiler?
Yes, but if the smell is strong, leave the house first and call 911 or the gas utility from outside. Once it is safe, we find the leak, repair the piping or fittings and test the system. We dispatch 24/7 for gas problems.
