Common Shower Problems We Fix in Lewisville

Shower issues don't all look the same, and they don't all need the same fix. Here are the most common problems we see homeowners dealing with:

• Leaking or dripping faucets and showerheads - Water waste and higher bills add up fast. A worn cartridge or valve seat is usually the culprit.
• Shower valve problems - The valve controls water flow and temperature. When it fails, you might get no hot water, unpredictable temperature swings, or water that won't shut off completely.
• Low water pressure - If your shower feels like a trickle, the issue could be mineral buildup, a clogged showerhead, a faulty valve, or problems deeper in your plumbing line.
• Tile leaks and moisture damage - Water seeping behind shower tile is serious. It can lead to hidden mold, rotting wood framing, and structural damage if it's not addressed quickly.
• Mold and mildew growth - High moisture in the shower area can create conditions where mold thrives. This is both a cleanliness issue and a health concern.
• Caulk failure and grout degradation - Over time, caulk and grout break down, letting water seep into areas it shouldn't reach.
• Cartridge and stem wear - These internal parts control how your faucet mixes hot and cold water. When they wear out, performance suffers.

Shower Valve Replacement and Repair

Your shower valve is the heart of the system. It's what lets you control water temperature, pressure, and flow. When it starts to fail, you'll notice problems pretty quickly.

Common signs your valve needs attention include water that won't turn off completely, temperature that swings wildly from hot to cold, a knob or handle that's hard to move, or water leaking from the valve body itself. These aren't minor annoyances - a failing valve can waste hundreds of gallons of water and lead to damage in your walls if water is escaping behind the scenes.

Fixing a shower valve depends on what's wrong. Sometimes a simple cartridge replacement solves the problem. Other times, the valve seat is damaged or mineral buildup is restricting flow. In some cases, the entire valve body needs replacement. We'll diagnose the exact issue, explain what we find, and let you know your repair options before we start any work. That step-by-step discussion is how we do business at Mack's Plumbing, TX LLC - no surprises, no mystery charges.

Valve replacement typically takes 1-2 hours for a straightforward job, though more complex situations might take longer. Our licensed technicians have handled hundreds of valve repairs in the Lewisville area, and we know how to work efficiently without cutting corners.

Faucet Cartridge Service and Replacement

The cartridge inside your shower faucet is a clever little piece of engineering. It's what lets you adjust water temperature with a small movement of the handle. But like any moving part, cartridges wear out over time.

A worn cartridge leads to:

• Difficulty turning the handle
• Water that leaks even when the handle is fully off
• Inconsistent temperature control
• A handle that feels loose or gritty

The good news is that cartridge replacement is a straightforward repair. We remove the old cartridge, install a new one that matches your faucet type, and test everything to make sure it's working smoothly. The whole process usually takes 30-45 minutes, and it's one of the most effective shower repairs we do.

Many people are surprised to learn that a simple cartridge replacement can solve problems they thought required replacing the whole faucet. Cartridges are built to be replaceable - that's by design. We stock common cartridge types, and we can usually have your shower working better the same day we diagnose the problem.

Diagnosing Low Shower Pressure

Low water pressure in the shower is one of the most common complaints we hear, and the frustration is real. A weak shower spray doesn't just feel bad - it can make basic cleaning take twice as long.

There are several reasons your shower pressure might be low. Here's what we check:

Showerhead clogging - Mineral buildup from hard water is the most common culprit. Over time, minerals accumulate inside the showerhead and block the spray ports. You can often fix this yourself by soaking the showerhead in vinegar, but sometimes replacement is the better option.

Valve problems - Your shower valve might be partially closed or damaged. We can adjust it or repair it depending on what we find.

Line blockage - Mineral buildup or debris deeper in your plumbing line could be restricting water flow. We use diagnostic techniques to pinpoint where the blockage is.

Pressure regulator issues - Some homes have pressure regulators that can fail or get stuck, reducing water pressure throughout the house.

Water main problems - In rare cases, the issue originates at the city water main. We can test your water pressure to determine if that's the cause.

We start by testing your water pressure with professional equipment. This tells us if the problem is just in your shower or throughout your house. Then we work backward to find the source. Sometimes the fix is as simple as cleaning a showerhead. Other times we need to replace a valve or clear a line. Either way, we'll explain what we find and what it'll take to get your pressure back to normal.

Tile Leak Repair and Moisture Remediation

Water leaking behind your shower tile is one of the most serious shower problems homeowners face - and it's often invisible until real damage has been done.

Here's how tile leaks happen: Water gets behind the tile through cracks in the grout or caulk, or through deteriorated waterproofing. Instead of draining out like it should, it sits in the space behind the tile, slowly soaking into the wood framing, insulation, and drywall. Over weeks and months, this leads to rot, structural damage, and mold growth.

By the time you notice a problem - like soft spots in the wall, discoloration, or a musty smell - there's often significant damage behind the scenes. That's why early detection and repair is so important.

The process we use to fix tile leaks depends on how much damage there is. If we catch it early, we might be able to replace the damaged caulk or grout and seal everything properly. If water has already penetrated into the wall structure, we need to open up the area, remove damaged materials, treat any mold, and rebuild with proper waterproofing in place.

This isn't a job to put off. Water damage gets exponentially more expensive the longer it's left alone. If you notice any signs of a tile leak - water stains, soft spots, cracks in grout, or any unusual moisture - we recommend getting it inspected as soon as possible.

Addressing Mold and Moisture Issues

Mold loves the shower environment. Constant moisture, warmth, and organic materials create perfect growing conditions. While a little surface mold or mildew is a cleaning issue, deeper mold growth is a health and structural concern.

Moisture problems in the shower area usually stem from one of these issues:

• Poor ventilation - A bathroom exhaust fan that's not running, too small, or not venting properly allows humidity to build up. Running your exhaust fan during and after showers is essential.
• Grout and caulk breakdown - When grout or caulk fails, water seeps into areas behind the tile where it can't dry out, creating ideal conditions for mold.
• Tile leaks - As we discussed, water penetrating behind tile creates hidden moisture that leads to mold growth.
• Condensation - Even without active leaks, condensation from hot showers can contribute to moisture buildup if it's not properly ventilated.

Our approach to mold and moisture remediation starts with finding the source. We identify where the moisture is coming from, assess the extent of the problem, and develop a plan to fix it. If there's active mold growth, we recommend involving a mold specialist. If the issue is structural moisture from a plumbing leak, we fix the leak and address the water damage.

In many cases, simply improving ventilation and repairing failed caulk or grout stops the problem from getting worse. Prevention is always better than dealing with advanced mold growth.

Repair Timelines and What to Expect

The time it takes to fix your shower depends on the specific problem, but here's a general breakdown of what we typically see:

Simple repairs - A cartridge replacement, faucet seat cleaning, or showerhead swap usually takes 30-60 minutes.

Moderate repairs - Valve replacement, significant caulk and grout work, or replacing worn internal parts typically takes 1-3 hours.

Complex repairs - Addressing tile leaks that have caused water damage, treating moisture issues, or major valve work might take 3-8 hours and could require follow-up visits.

Some jobs finish in one appointment. Others might require us to come back once materials arrive or if we discover additional issues once we're into the work. We'll let you know what to expect before we start.

The timeline also affects cost, which is why getting an accurate diagnosis early matters. A small problem caught quickly stays small. A small problem ignored becomes a big, expensive problem.
