Most Klein homes were built between the 1970s and the 1990s, which means the plumbing is now at the age where things start announcing themselves. Cast iron drain lines corrode. Original water heaters are long past due. Roots from those big pines find their way into sewer pipe. Molberg Plumbing works on all of it, plus everything a newer home needs. We’re licensed, family-owned, and known for telling customers the truth about what their plumbing requires, including when the answer is that it can wait. Drain cleaning, sewer repair, leak detection, water heaters, gas lines, repiping, and emergency service are all part of what we do in Klein.

A burst pipe or a sewer backup gets worse every hour it sits. Our emergency service responds to Klein calls and will help you find and close your main shutoff while a licensed tech is on the way. The first job is stopping the damage. The second is figuring out exactly what failed and why. Then we give you your options, the cost of each, and the time to decide.

We repair water lines, sewer and drain pipe, fixtures, valves, pressure regulators, and water heaters, and we take the time to find the real source before quoting anything. In Klein’s older neighborhoods that often means checking for cast iron deterioration rather than assuming a simple clog. Our trucks carry the common parts, so most repairs finish on the first trip.
When repair stops making sense, we install the replacement properly. That includes traditional and tankless water heaters, gas lines, water softeners and filtration, sump pumps, garbage disposals, sewer and water line replacements, and fixtures for kitchen and bath remodels. We price it up front and offer financing so a big job doesn’t have to wait.
Older plumbing rewards attention. Annual maintenance means flushing the water heater, inspecting the anode rod, testing water pressure, checking supply lines and angle stops, and clearing early drain buildup. Our VIP Membership keeps it scheduled and adds priority service, which matters when half the neighborhood calls a plumber after the same freeze.

You shouldn’t have to break concrete to find out where a leak is. We locate slab and wall leaks with infrared imaging and acoustic equipment, and we inspect drain lines from the inside with sewer cameras. For Klein homes with original cast iron, a camera inspection tells you whether you’re looking at another few good years or a replacement conversation.
Gurgling toilets, standing water in a tub, and sewage odors all point to a restricted line. We clear the blockage first, then camera the pipe to find out what caused it. Hydro jetting removes grease, scale, and root intrusion from the full pipe diameter, which keeps drains flowing much longer than a cable alone, especially in neighborhoods with mature trees.
Our licensed plumbers install new gas lines, repair damaged ones, and pressure test full systems. Adding a gas range, a tankless water heater, an outdoor kitchen, or a standby generator means the line has to be sized for the total load, and we work that out before installation. Suspect a leak? Get out of the house and call us from outside.
Heavy Gulf Coast rain finds the low spots, and a sump pump only helps if it’s working when that happens. We install new pumps, replace failed units, test float switches and check valves, and confirm the discharge line moves water far enough from the house. If yours hasn’t been tested since you moved in, that’s worth fixing before hurricane season.
Corrosion, soil movement, and age are what take out water lines in Klein. We locate leaks, repair or replace failing sections, and run new supply lines where you need them. When a home starts seeing repeat pinhole leaks, discolored water, or pressure that keeps dropping, we’ll walk you through whether a full repipe is the smarter spend.

Repairs usually happen on the spot. Bigger jobs get scheduled around you, and every job is backed by our workmanship warranty.

Schools, offices, restaurants, and retail properties around Klein need plumbing that holds up under constant use. We handle commercial water heaters, restroom fixtures, grease line service, backflow assemblies, and drain maintenance, and we schedule work around your hours whenever we can. Maintenance agreements are available for properties that want fewer emergency calls.
Cast iron drain lines nearing the end of their service life, original water heaters, galvanized supply lines that have narrowed, and hose bibs or shutoff valves that no longer close fully. A plumbing inspection with a sewer camera gives you a clear picture of where you stand.
Usually under an hour for a typical home. You get to see the footage, and we explain what we’re looking at rather than just handing over a report full of terminology.
Sometimes. Descaling and lining can extend the life of a line that’s corroded but structurally intact. When the pipe has cracked, collapsed, or separated, replacement is the right call. Our Picote certification means we can do a lot of that work without heavy excavation.
Regularly. Roots follow moisture, and any small crack or loose joint gives them an entry point. Once inside, they grow and trap everything moving through the pipe. Jetting removes them, and a camera shows whether the pipe itself needs repair.
Often, yes. Availability depends on the day and the call volume, and emergencies take priority. Let us know what’s happening and we’ll tell you honestly when we can be there.
You get a price for the job before we start, not an hourly meter running while you wonder what the total will be. Estimates are free and the number we give you is the number.
