"Kerrville Plumbing did an all around great job removing and replacing two toilets for us.They were helpful in finding the exact, difficult to find toilets I wanted. They were helpful price they quoted was very fair. Two plumbers arrived promptly, got everything done in about an hour, and cleaned up after the installation. It was great doing business with them and I would definitely hire then again in the future."

"James and Jaime arrived at my residence with a professional and friendly demeanor. Their first impressions was consistent from start to finish. Upon there arrival they quickly assessed the work to be done and began replacing my old water softener with a new one. After completing the plumbing reconfiguration, James and Jaime gave me a tutorial to program the new water softener. When the work was completed, the two gentlemen picked the trash and carried away my old water softener. The cost for services was reasonable and the office will work with you on any questions regarding reasonable cost adjustments. I would use Aaron and Hager Plumbing (new business name soon to be "Eager Plumbing") for future plumbing needs."

"Excellent! Could not have chosen a better contractor to do my required work. Jose and crew gave full attention to every detail, from keeping me informed, staying on schedule as permitted, and very knowledgeable in the various materials that were possible to be used. After completion their job clean-up was thorough, loading and hauling off unused material. I absolutely would hire JC Construction again, in fact, already have another job in the making for he and his crew! My yard looks great, thanks to JC Construction!"

"Ed and his crew were fantastic to work with.  I called for an estimate and he called me back the next day and came out to give an estimate.  he arrived on time and was extremely friendly.  I showed him my issues and he gave me a fair estimate.  He was actually significantly cheaper than some other estimates I had received.  Due to his outstanding Angie's list rating and the great estimate I asked them when they could do the work.  They came out two days later, arrived when they said they would. They got straight to work and completed the work in less time than I expected.  Ed took his time explaining what had caused my problems and what they did to fix the issue.  His work comes with a 5 year transferable warranty. 
I was extremely pleased with the price and the work performed.  I was equally impressed with Ed himself.  It was nice to find an honest, trustworthy and competent businessman to perform the work I needed done.  I would recommened E-Tex Foundation Repair to anyone. 
Thank you Ed and crew for a job well done.

Foundation Drain Installation FAQs, answered by experts

A sewage ejector pump is necessary if you have any plumbing fixtures, such as a bathroom, laundry room, or sink, located below the level of your home's main sewer line. Standard plumbing relies on gravity to drain wastewater and solid waste into the municipal sewer system or a septic tank. For fixtures below this level, like those in a basement, gravity cannot move the waste upward. The ejector pump provides the force needed to pump the sewage up to the main line. Without one, wastewater from below-ground fixtures would back up, potentially causing a sewage overflow and flooding. If all of your plumbing is on the main floor or higher, gravity is sufficient and an ejector pump is not needed.

Yes, a well-maintained sump pump can increase a home's value and make it more desirable to potential buyers; it does not lower property value. By protecting the basement from flooding and water damage, a sump pump provides peace of mind and can make the space usable for storage or as an extra room. For buyers interested in homes with basements, a working sump pump is a significant feature that adds value by ensuring the space is secure and less likely to flood.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

Not all window wells have a formal drain, but they all require a method for water to flow away from the window. Some wells are connected to an interior or exterior drain tile, which is the most effective solution. Others rely on a deep layer of gravel or crushed stone that allows water to filter down into the soil.

However, if a window well lacks a proper drainage system, it can lead to basement seepage, costly water damage, mold growth, and potential foundation damage. This is especially true in areas with heavy rainfall or expansive soil.

If your window well doesn't have a drain or is not draining quickly enough, you have a few options. For gravel-based systems, the stone may have compacted and needs to be improved. For a more robust solution, you can hire a plumber or window installer to connect the well to a drainage system. This can also be a DIY project using a shovel or auger.

Sump pumps prevent basement flooding, reduce humidity, and protect against water damage.
