Leak Detection and Repair Services

If you suspect you have a leak, the time to address it is now so that you can minimize any water damage to your home.

Kowalski will find the source of your leak, correct the issue, and repair or replace the necessary plumbing.

We also have a wide network of Pittsburgh contractors we call on, such as roofers, plasterers, flooring professionals, and builders, who can restore any parts of your home affected by leaks.

Do You Need Leak Detection and Repair Services?

Obviously, if you see water escaping from a fixture or pooling somewhere in your home, you need leak repair.

But many leaks are hidden inside your walls, under your floors, or deep in your supply or drain lines.

Here are some signs that you may be dealing with a hidden leak:

A sudden increase in your water bill ● Low water volume ● Cracks or stains on ceilings, walls, or floors ● Visible mold or mildew ● Unevenness or hot spots on floors ● The sound of dripping or running water that you can’t locate

Leak Services We Offer

Advanced Leak Detection

We identify the source of leaks using acoustic listening devices, temperature sensors, and drain cameras. We pinpoint search areas quickly to find both active and impending leaks.

Drain Cleaning

Our drain services may be the answer to your leaks, which are often caused by clogged or corroded pipes.

Pipe Repair

Kowalski restores or replaces leaking or burst pipes. Whenever possible we use minimally invasive methods. When necessary, we dig trenches and then refill them cleanly and carefully.

Slab Leak Repair

A slab leak is a leak from the water or sewer lines under your home’s floor or foundation. This can happen with aging or improperly installed pipes, extreme weather, or hard water.

Fixture Leak Repair

Even the best plumbing equipment can spring a leak. We repair everyday plumbing leaks such as those from your faucets, sinks, toilets, and other fixtures.

Kitchen and Bathroom Remodeling

At Kowalski, we have a design mindset, so kitchen and bathroom remodels are among our favorite projects to take on. We believe that your plumbing needs to perform superbly, plus look fantastic and integrate well into your space.

We offer remodeling services to make Pittsburgh’s kitchens and bathrooms places of beauty, comfort, and craftsmanship.

Why a Plumber for Your Kitchen or Bathroom Remodel?

Your general contractor may be great (we know many of them in Pittsburgh!), but a remodeling project is filled with critical plumbing decisions and tasks. These belong in the hands of a master plumber, who can partner with your contractor for the best results.

Kowalski is the plumbing expert you need. Here are the reasons to work with us for your remodeling project:

To Minimize Surprises

We’ll help you determine whether the plumbing in your home supports a remodel before you make huge purchases or start opening walls.

To Develop a Workable Design

We’ll guide you in the footprint, materials, fixtures, brands, and new technologies that will look gorgeous and work well in your space.

To Upgrade Your Plumbing System

A remodel may require repiping. Attaching new fixtures to outdated plumbing only sets you up for more repairs too soon.

To Make Big Changes

If you’re swapping fixture locations or types (like a tub for a shower or vice versa), you need a plan, site preparation, and workmanship from a professional.

To Ensure Your Safety

We maneuver heavy fixtures, manage water shutoff and pressurization, implement proper venting, and ensure everything is up to code.

To Keep Things Clean

Remodels often involve waste and sewer lines. You won’t regret leaving these lines to the professionals.

To Lower Your Costs

An expert plumbing installation that's custom tailored for your home will perform better, and save you money, over the long run.

To Make Smaller Remodels Convenient

We work with carpenters and other pros to complete smaller remodeling jobs from start to finish. This saves you the hassle of coordinating multiple contractors.

Outfit Your New Kitchen or Bathroom with the Pittsburgh’s Most Well-Designed Plumbing

Heating and Conditioning Your Water

Beyond ensuring that your water flows securely and drains well, Kowalski helps you improve its quality for a healthier and more comfortable home.

Water Heaters

Get the perfect supply of hot water for your home and family. We install and replace all types and sizes of hot water heaters, plus customize and secure their fittings.

On-Demand Hot Water

Equip your home with endless hot water. We install and maintain tankless systems that heat water only when you need it. On-demand hot water is not only convenient but energy efficient - and increasingly affordable.

Water Filtration Systems

Remove the impurities from your water so you can enjoy safer drinking and cooking, a better-preserved plumbing system, and fewer clogs and leaks. We install whole-home water filtration systems and can help you determine if one is right for you.

Water Softeners

Eliminate the chemicals in your water that corrode pipes, cause appliance wear and tear, and dry your skin. We install whole-home water softeners that protect your plumbing, health, and wallet from the effects of hard water.

Sewer, Gas, and Water Line Services

Your sewer, gas, and water lines are the arteries and veins of your home. They carry staggering amounts of critical cargo to your house and away from it.

And they’re mostly underground, subject to shifting soil, encroaching roots, and pressure over time.

Kowalski expertly repairs and replaces sewer, gas, and water lines, whether yours are suffering from typical wear and tear – like cracks and corrosion – to full-on collapse.

If you are having an emergency with a sewer, gas, or water line, such as an overflow, severe backup, gas leak, or burst pipes:
Call us at 724-745-7404 or 412-952-5923
