"I needed a solution to redirecting water that was pooling in my yard from my home’s gutter downspouts. The downspouts needed to be buried and moved away from the house, some drains added and low lawn spots regraded. After a number of consults from other companies trying to sell me costly drain systems and unneeded products, Freedom Land Services was clearly the best choice and top tier. Consultation, punctuality, professionalism, expertise, communication, fast completion, no up-selling and honest pricing, informative, and my yard was left so very clean and tidy during the project and after. I really appreciate the time and attention to detail Adam and his team took to customize and execute my project, and it works flawlessly. I couldn’t be more thrilled with the results!"

"Initially we thought we had found a good company to service our well issue. They came out immediately to look at issue and gave us a solution we thought to our problem. Within a month, our well again was flooding well house and should have been covered under their warranty. We called multiple times and finally connected to be serviced. That day came any went without anyone showing up or calling to reschedule. Follow up calls got us nowhere until I left a message that if I didn?t get a callback, I would place an honest review on the bad service and unprofessional message from them. The well guy called back with excuse everyone at company had flu and to go ahead and leave a negative review. So here it is.

If the well guy would kindly correct this situation, I would in turn follow up with a positive review of them correcting a situation for a customer. "

FAQs for septic tank service projects in San Marcos, TX
The cost to replace a septic tank is $7,350 for the average homeowner. This cost can range, however, from $470 to $22,500, depending on several factors. Your house size is a significant factor in the overall cost, but other things like material type impact the final price tag. For example, installing a new septic tank in a one-bedroom house typically costs $500 to $900, whereas installing a new septic tank in a five or six-bedroom home is generally $1,200 to $1,600.
Yes, most states require septic tank installers to have a license, and for good reason. Hiring an unlicensed septic tank pro could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
The cost of septic tank repair is $1,775 for the average homeowner. However, depending on a few elements, you might pay as little as $170 or as much as $6,100. Location, repair type, and tank material all determine the final cost. For example, replacing the septic tank filter can be as little as $200 to $300. However, repairing septic lines costs more, averaging around $1,500.
A septic tank can typically last 15 to 20 years on average, though your system's lifespan will vary depending on the type of septic system and the materials used. To help increase your septic tank's lifespan, schedule routine maintenance and do not flush items like cat litter, cigarette butts, or paper towels.
Repairing or replacing a septic tank is a job best left to a professional. Your septic tank is an essential part of your home, and if installed or repaired incorrectly, it could lead to significant problems. Things like polluted water, property damage, and health risks to your family could all happen as a result of an improper septic tank repair or installation.
