What We Do

Plumbing Services for Wilmington Homes and Businesses

From a dripping faucet to a full repipe, we cover the plumbing in your home or building from the water main to the sewer line. Each service below has its own page with the warning signs to watch for, how the work is done and what affects the cost.

If you are not sure which service you need, that is fine. Describe what you are seeing when you call, and a plumber will help you figure out the next step. You can also call with a question before you book anything.

Most calls fall into a few groups: hot water problems, leaks and pipe damage, clogged drains and sewer lines, water quality, and new fixtures or remodel work. Commercial customers get the same range of services, plus backflow testing, grease traps and larger water heaters built for heavy use. Whatever the job, you work with a plumber in Wilmington, DE who explains the plan before starting.

Water Heaters, Repiping and Cleaner Water at Home

Hot Water

Three kinds of work make up a large share of what we do, and hot water comes first. We handle water heater repair, full replacements and tankless water heater installation, so a cold shower turns into a quick fix instead of a long wait. Gas and electric tank heaters both last longer with regular care, and a yearly flush helps clear the sediment that wears them out. We look at the age of your unit, how much hot water your household uses and where the heater sits before recommending anything.

Repiping

Aging pipes are the second. Many homes in and around Wilmington still have galvanized steel or other dated piping that corrodes, restricts flow and leaks. Whole house repiping replaces the old lines with modern materials, restores water pressure and removes the worry of the next hidden leak. It is a big project, and we plan it to keep walls opened and water shut off to a minimum.

Cleaner Water

Water quality is the third. Hard water, iron stains, sulfur odors and well water concerns can all be solved with the right equipment. Our water treatment systems and filtration options are matched to what is actually in your water, never sold as a one size fits all package. A water test shows what is in your supply, and that result guides the recommendation, whether it is a softener, a whole house filter or a reverse osmosis system for drinking water.

How It Works

How a Plumbing Visit With Us Works

Every job follows the same simple steps, whether it is a running toilet or a new water heater. You always know what we found, what it will take and what happens next, so there are no surprises when the work is done.

Before any work starts, you know the scope of the job and the price. If we find something else along the way, such as a corroded shutoff valve or a slow leak behind a wall, we point it out and let you decide whether to deal with it now or later. That way you stay in control of your home and your budget.

  1. Tell Us What Is Happening

    Call or send a request with a short description of the problem. We will ask a few questions and arrange a visit at a time that works for you.

  2. On-Site Diagnosis

    A plumber inspects the problem, tests the fixtures or equipment involved and tracks down the real cause instead of guessing.

  3. Clear Options

    You get a plain explanation and your choices before any work begins, with no pressure to pick the biggest job.

  4. Work Done and Checked

    We complete the repair or installation, test everything to make sure it works and leave the area as clean as we found it.

    Needed to get my A/C fixed and he came right out and discussed the issue where I could fully understand the problem and he gave me options to move forward which I appreciated. He also fixed two separate plumbing issues a year later and service each time was fantastic.

Questions About Hiring a Plumber in Wilmington, DE

Do you offer 24/7 emergency plumbing in Wilmington?

Yes. Supreme Plumbing Services has 24/7 emergency service available for burst pipes, major leaks, sewer backups and water heater failures. If water is spreading, shut off the main water valve first, then call (302) 750-0115. Our emergency plumbing page explains what to do while you wait for a plumber to arrive.

Are your plumbers licensed and insured?

Yes. Our plumbers are licensed and insured, which protects your home and makes sure the work meets plumbing code. We are happy to answer questions about our licensing before we begin any job. Hiring a licensed plumber also matters for permits, inspections and home sales, where unlicensed work can cause problems later.

Do you work on both homes and businesses?

We do. Our team handles residential plumbing for houses, townhomes and apartments, and commercial plumbing for offices, restaurants, retail spaces and other properties. Commercial clients can count on the same honest diagnosis and clean, careful work, with services such as backflow testing and grease trap cleaning.

Should I repair or replace my old water heater?

It depends on the age of the tank and what has failed. Replacing a thermostat, element or valve often gives an older unit more years of service. A tank that leaks from the body or shows heavy corrosion should be replaced. We inspect the heater and give you an honest recommendation before any work starts.

What areas outside Wilmington do you serve?

We serve the tri-state area within about 60 miles of Wilmington, including Newark, Middletown and New Castle in Delaware, Elkton and Chester in Maryland, and Kennett Square and West Chester in Pennsylvania. If your town is not listed, call us and we will tell you whether it is within our service area.
