How to Tell If You Have a Gas Leak: Warning Signs Every San Antonio Homeowner Should Know

12Dec2024

Knowing how to tell if you have a gas leak is an important part of keeping your home and family safe. Natural gas powers many household appliances, including stoves, furnaces, and water heaters, but a leaking gas line can create serious safety hazards if left unaddressed.

Fortunately, there are several warning signs homeowners can recognize, from unusual smells to hissing sounds near gas appliances. Whether you’re concerned about your kitchen, heating system, or outdoor gas lines, knowing what to look for and how to respond can make all the difference.

If you suspect an active gas leak, leave your home immediately. Do not use electrical switches, appliances, or phones while inside. Once you’re safely outside and away from the building, call 911 or your gas utility’s emergency number. Do not return until emergency responders or the gas utility confirm it is safe.

Mountain Cedar Season: When It Begins, Ends and How to Survive It

4Dec2024

If you’ve lived in Central Texas for a while, chances are you’ve experienced the dreaded “cedar fever.” Mountain Cedar allergy season starts in late December and can last until March. The most severe months are usually December and January, which is when the cedar’s pollen counts are at their peak. The symptoms of cedar fever are similar to those of a cold: sneezing, itchy eyes, a sore throat, runny nose and general fatigue. It’s an attack on your immune system and can leave you open to contracting other illnesses.

Signs of Animals in Your Attic (and What They Can Do to Your AC Ducts)

25Nov2024

Hearing scratching above your ceiling or noticing strange smells coming from your attic? You may have some unwanted visitors. Knowing the signs of animals in your attic can help you catch a problem early, before it leads to damage throughout your home.

In San Antonio, rats, squirrels, and raccoons can find their way into attics looking for shelter. While most homeowners focus on getting the animals out, there’s another concern that’s easy to overlook: the damage they may leave behind in your HVAC system.

From chewed air ducts to damaged insulation, attic pests can affect your home’s comfort, energy efficiency, and indoor air quality long after they’ve been removed.

Why Does My Water Take so Long to Heat Up in San Antonio?

6Nov2024

Do you find yourself waiting a long time for hot water? If your water takes longer than 30–40 seconds to heat up, it’s not only a waste of your time—it also drives up water, sewage and electric bills.

You might be wondering what’s taking so long. Well, the time it takes hot water to reach a fixture depends on 4 things:

The distance from the fixture to the water heater
The fixture’s flow rate
The material of your supply pipes
The age of your water heater and its condition

We’ll go over how these factors impact hot water time. Then, we’ll go over how you can get hot water faster.

Shafer does wondeful work. Diego was polite and friendly. He explained everything.

Dustin was very patient kind and professional with me. He made sure that I understood and was explained everything that I needed to know about the condition of the AC unit. I cannot thank him enough for being so kind with me. I cannot think Shafer enough for the service. I am continuing to save for the extension of my heating system downstairs. Thank you.

Franc went above and beyond with multiple plumbing issues I was having. He found the clean out drain when I could not and cleared the obstruction 60 ft. from my house. He then repaired the rock pathway I had dug up trying to find the drain. He checked faucets and cleared drains in one bathroom. He fixed a toilet and a stuck cold water faucet in another. The whole time he kept me informed and answered all of my questions.

Diego was extremely professional and honest. I’m so glad I found someone who didn’t try to swindle me like others have in the past. I also appreciated his honesty about another question I had. He gave me a realistic answer and explained why it wasn’t something that could be done (I mean….it could but it would be a headache), which was a relief. Other plumbers told me it was possible and wanted to charge me an arm and a leg. I’ve had my tankless water heater flushed annually in the past, so I was happy to hear there wasn’t much buildup. Keep up with your annual flushes, everyone! Preventive maintenance makes a difference!

Frank was outstanding! He was extremely knowledgeable, friendly, and professional throughout the entire service call. He took the time to explain everything clearly, answered all of my questions, and was completely transparent about the services needed and the pricing involved. There were no surprises, and I truly appreciated his honesty and expertise. If you're looking for a trustworthy plumber who provides excellent customer service, I highly recommend Frank!

Mary Fritschle

Wow. They were pretty quick to get here and save me from a night without air conditioning. And the serviceman was still friendly at 9:00 at night.
