What we do

Plumbing services across Catonsville and Baltimore County

27 services covering everything from a running toilet to a full repipe. Every one of them starts the same way — we look at the problem, tell you what it is, and give you the price before we start.

Emergency Plumbing

Burst pipes, sewer backups and dead water heaters do not wait for business hours. Neither do we — a real plumber answers, day or night.

Learn more

Drain Cleaning

We clear the clog, then camera the line to show you what caused it — because in an older Catonsville home a slow drain is rarely just hair and soap.

Learn more

Sewer Line Repair

Roots, bellies and cracked clay laterals — diagnosed on camera and repaired with the least digging your yard can get away with.

Learn more

Sump Pump Services

Storms here knock the power out exactly when your pump matters most. We size, install and back up pumps that actually run when the grid does not.

Learn more

Water Heater Repair & Installation

Repairs on every brand, tank or tankless — plus a free hard water test, because Catonsville water is why most heaters here die early.

Learn more

Water Softeners & Filtration

Free hardness testing on every visit, then softeners and filtration sized for Catonsville water — the fix that makes every other plumbing repair last longer.

Learn more

Leak Detection & Repair

Electronic detection finds the leak before the drywall comes down. We locate it precisely, then repair it with the smallest opening the job allows.

Learn more

Water Line Repair

The buried line from the meter to your house is yours to maintain. We find the failure, then repair or replace it with as little digging as possible.

Learn more

Whole-House Repiping

When a house starts leaking in a second place, patching stops being the cheap option. We repipe in stages or all at once, with the smallest openings possible.

Learn more

Bathroom Plumbing & Remodels

From a stuck shower valve to a full bathroom re-plumb — including the older Catonsville bathrooms where nothing is standard size.

Learn more

Kitchen Plumbing

Disposals, faucets, sinks, ice maker and dishwasher lines — plus the grease-loaded kitchen drains that older Catonsville homes are famous for.

Learn more

Toilet Repair & Installation

Running, clogged, rocking or leaking — including the rotted flanges and non-standard roughs that older Catonsville bathrooms hide.

Learn more

Residential Plumbing Repairs

The ordinary stuff done properly — dripping valves, weak fixtures, mystery noises and the small failures that turn expensive if ignored.

Learn more

Leaky Pipe Repair

We repair the leak and then pressure-test the run — because in an older house the drip you found is often the second-oldest problem in the wall.

Learn more

Clogged Pipe Repair

When clearing stops working, the pipe itself is the problem. We find out which section, how bad, and what it takes to fix properly.

Learn more

Slab Leak Repair

Warm patches on the floor and a bill that doubled. We locate it precisely, then price both a spot repair and a re-route so you can choose.

Learn more

Flood & Water Emergencies

Water coming in faster than it goes out. We stop the source, get the water moving, and tell you what caused it before it happens again.

Learn more

Faucet Installation & Repair

Drips, weak flow and seized handles — usually a cartridge and an aerator, not a new faucet. We will tell you which.

Learn more

Bathtub & Shower Installation

Tubs, shower pans and tub-to-shower conversions — done with the drain, slope and valve depth right, because tile hides everything.

Learn more

Plumbing Installation

New lines to new places — a basement bath, a laundry relocation, an addition. Permitted, vented properly and inspected before it is covered.

Learn more

Home Water System Upgrades

Treating the water system as one thing — supply, pressure, heating, treatment and distribution — instead of five separate service calls.

Learn more

Remodeling Plumbing

The plumbing side of a renovation, coordinated with your other trades and inspected before anything gets covered up.

Learn more

Plumbing Maintenance

An annual visit that catches the cheap problems before they become the expensive ones. In hard-water Catonsville it pays for itself.

Learn more

Gas Line Services

New gas runs for ranges, grills, dryers and generators, plus leak testing and repair — permitted, pressure-tested and inspected.

Learn more

Video Pipe Inspection

A camera turns a guess into a diagnosis. Essential before you buy an older Catonsville home, remodel a bathroom, or agree to any sewer repair.

Learn more

Historic Home Plumbing

Pre-1950 houses need a different approach. We upgrade galvanized supply and cast iron drainage without tearing apart what makes the house worth owning.

Learn more

Commercial Plumbing

Restaurants, offices, salons, retail and rental property along Frederick Road and beyond — with a response time that respects the fact you are losing money.

Why Catonsville calls us

Six reasons homeowners keep our number

We are not the cheapest plumber in Baltimore County and we do not try to be. What we offer is the thing people actually want from a trade: a straight answer, a fair price, and work that does not need doing again.

A family business, not a franchise

You get the same faces on every visit. Our reviews name Danny by name because that is who turns up. National chains send whoever is on the rota and start the explanation from scratch each time.

Older homes are our specialty

Galvanized supply, cast iron stacks, ten-inch toilet roughs and plaster walls are normal working conditions for us. We plan around them instead of being surprised by them halfway through your job.

Free hard water testing, every visit

Catonsville water runs 7–8.2 grains per gallon. That is why heaters die early here. We test on the spot at no charge, and if the number does not justify equipment we say so.

Price before work, in writing

You hear the number before we pick up a tool — including whether this is the permanent fix or a stop-the-bleeding repair. No hourly open-ended billing, no surprise add-ons.

Permits pulled, inspections met

Water heaters, sewer work and gas piping all require Baltimore County permits. We file them and meet the inspector. Un-permitted work has a way of surfacing at the worst moment in a home sale.

We clean up after ourselves

Our customers write about this more than anything else. Drop cloths, shoe covers, containment around the work area, and a floor left the way we found it. It is not optional here.

What working here actually teaches you

Four things about Catonsville plumbing that a national chain will not know

Every town has its own failure patterns. These are ours — the water, the housing stock, the trees and the weather. Knowing them before we arrive is the difference between a diagnosis and a guess.

The water: 7–8.2 grains, and it is why heaters die here

Catonsville runs on Baltimore City surface water, which arrives at roughly 120–141 PPM — about 7–8.2 grains per gallon. That is moderately hard to hard, and every gallon of it that gets heated leaves calcium behind on the bottom of the tank. A heater rated for ten to twelve years commonly gives six to eight here if nobody ever addressed the water. We test hardness free on every visit and show you the reading, because the number changes the recommendation.

More on water softeners and filtration

The houses: pre-1950 stock with pre-1950 problems

Thousands of homes here were built before 1950, especially off Frederick Road and through Paradise and Westchester. The pattern is consistent: galvanized supply corroding from the inside so pressure drops room by room, cast iron drainage that scales and cracks, and venting that was never sized for the bathrooms since added. If your house predates 1986, the supply lines are also worth checking for lead solder.

More on historic home plumbing

The trees: mature roots and clay laterals do not mix

The tree canopy is part of why people move here, and it is the single most common cause of sewer backups we get called to. Roots find the joints in old clay and cast iron laterals, then catch everything that passes. If your property has mature trees, a camera inspection every two or three years costs a fraction of an emergency dig and tells you years in advance which way this is going.

More on camera inspection

The seasons: two predictable spikes every year

Freeze calls cluster in the small hours of a cold snap, on pipes running through crawl spaces, garages and exterior walls — the runs nobody insulated. Then storm season overwhelms sump pumps, and the power tends to fail at exactly the moment the pump matters most, which is the whole argument for a battery backup. Both are cheap to prevent and expensive to clean up after.

More on sump pumps and backups

All of it runs through Baltimore County, which means water heater replacements, sewer work and gas piping need permits and an inspection. We file them and meet the inspector ourselves — un-permitted work has a habit of surfacing at the worst possible moment, usually during a home sale.

The Collins & Sons LLC family plumbing team outside their Catonsville, MD shop

Locally owned & operated

Three generations of Maryland plumbers, based on Westowne Road

We are a family owned and operated business dedicated to providing quality service to your home water system. We specialize in residential repairs, remodels, and upgrades. With over 40 years of experience, Collins & Sons, LLC is the right choice for your home.

Catonsville is not a service area on a map for us — it is where the trucks park at night. We have worked on the 1920s bungalows off Frederick Road, the colonials through Westchester and Oak Forest, and the newer builds out toward Rolling Road. There is a fair chance we have been inside a house on your street.

That matters because this town is really several housing stocks living side by side, and the right answer changes with the era. Knowing which one you have before we arrive is what keeps the estimate honest.

Most requested

The five calls we take most often

If one of these is why you are here, the service page will tell you what the job involves, what drives the price, and what we would check first.

Where we work

132 service areas across 7 Maryland counties

Based in Catonsville, working across Baltimore County, MD, Howard County, MD, Anne Arundel County, MD, Carroll County, MD, Frederick County, MD and Anne Arundel County. Response times are fastest in 21228 and 21229 — pick your town for the local detail.

What it costs

How we price the work, in plain terms

Sticker shock is the complaint we hear most about other plumbers, and almost all of it comes from finding out the number too late. Here is how ours works, before you call.

You get the number before we pick up a tool

In writing, after we have looked at the job. We will not quote blind over the phone, because a guess that turns out low helps nobody — but we will tell you what drives the cost so the figure is not a surprise when it comes.

Priced by the job, not by the hour

An open-ended hourly clock rewards the slow plumber and punishes you for a hard access. You agree a price for the work, and if the job turns out to be something other than what we quoted, we stop and have that conversation before continuing.

Free estimates on the big ones

Water heater replacement, sewer line work and whole-house repiping are free to estimate, with no obligation. Diagnostic service calls carry a service charge — we tell you what it is on the phone before we dispatch, never as a line item you discover on the invoice.

Repair or replace, answered honestly

Sometimes the right answer is the cheaper one. We say so, and we tell you how much life a repair is likely to buy, so you are choosing between real options rather than being sold the larger of two.

We do not publish a rate card, because the honest range for most of this work depends on what the house turns out to be doing — and a number on a page that does not survive contact with your basement is worse than no number at all. What we will commit to is that you hear the figure, and what drives it, before anything starts.

  • I had an outstanding experience with Collins & Sons LLC. Daniel has done several projects at my home over the last 4 years. He has helped me with small projects (replacing a garbage disposal), large projects (renovating my patio) and random projects. No matter the scope or size of the project, he treats his work and customers the same — with utmost professionalism, respect, and courtesy. With Daniel, you will be collaborating with a contractor who is a good guy, focused on customer service and not hustling to get more money. I highly recommend him for any contracting needs.

  • Needed a water heater and my upstairs plumbing replaced. After contacting them they were very flexible to my schedule, also explaining in detail costs and procedures. Who doesn't like an honest family owned professional? I would use them again any time and definitely recommend them.

  • Danny replaced my bathroom exhaust fan recently and I'm SO HAPPY! He went to Home Depot with me and explained the replacement options and I'm happy with what we chose. He also took a look at my sump pump while he was here and performed some simple magic that seems to have stopped my basement from flooding after every heavy rain. He's an invaluable resource. Thanks Collins and Sons!

Common questions

Plumbing questions Catonsville homeowners ask us

Do you offer 24/7 emergency plumbing in Catonsville?

Yes. We answer the phone around the clock for burst pipes, sewer backups, gas smells and water heater failures. Collins & Sons is family owned and operated, so you reach someone who knows the trucks and the neighborhood rather than an answering service.

What areas do you serve?

We are based at 209 Westowne Rd in Catonsville and work across Baltimore County, Howard County, Anne Arundel County, Carroll County, Frederick County and Montgomery County. Response times are fastest in 21228, 21229 and the surrounding communities. Every city we cover has its own page under Service Areas.

Are you licensed and insured?

Yes. Collins & Sons LLC holds Maryland Home Improvement Commission license MHIC #117712 and carries full liability insurance. We also pull the permits required for water heater replacements, sewer work and gas piping, and we meet the inspector ourselves.

How much will my plumbing repair cost?

You get the price before we start any work, in writing. We will not quote a number over the phone without seeing the job, because guessing helps nobody — but we will explain exactly what drives the cost, and we tell you honestly when a repair makes more sense than a replacement.

Why do water heaters fail so quickly in Catonsville?

Hard water. Our supply runs roughly 120 to 141 PPM, about 7 to 8.2 grains per gallon, and that scale plates out on the bottom of the tank or inside a tankless heat exchanger. A unit rated for ten to twelve years commonly gives six to eight here without treatment or annual flushing. We test your hardness free on every visit.

Do you work on older homes?

It is most of what we do. Catonsville has one of the higher concentrations of pre-1950 housing in Baltimore County, which means galvanized supply lines, cast iron drainage, plaster-and-lath walls and non-standard fixture roughs. We plan around those conditions rather than being surprised by them.

How long have you been in business?

Collins & Sons LLC brings more than 40 years of experience to Maryland homes. We are a family owned and operated business specializing in residential repairs, remodels and upgrades to your home water system.

Do you offer free estimates?

We provide free, no-obligation estimates for larger projects such as water heater replacement, sewer line work and whole-house repiping. For diagnostic service calls there is a service charge, which we tell you about on the phone before we dispatch — never as a surprise on the invoice.
