"AVOID AT ALL COSTS!!! Here is a list so you can read everything we’ve been through with this company. Spent over $11,000 in 2020 to have interior drain tile and a landing drain connected to a new sump pump Had water enter through the doorway by the drain 3 times since 2020, with the most water coming inside September of 2022 Called Safeguard in September 2022. Safeguard refused to even check the system, sent us a quote for $1,800 more work to “fix us up” without even checking anything on our property Had a 3rd party company out to inspect the drain that Safeguard refused to check. Discovered they breached our contract and connected the drain to village stormwater tiling without our consent or the consent of the village. Have never received as much as an apology. Instead, Safeguard blamed us saying the drain was clogged with leaves, and that is why we flooded. This was disproved by Roto-Rooter. Update as of 3/3/2023 AVOID AT ALL COSTS!!! Here is a list so you can read everything we’ve been through with this company. Spent over $10,800 in 2020 to have interior drain tile and a landing drain connected to a new sump pump. Had water enter through the doorway by the drain 3 times since 2020, with the most water coming inside September of 2022. Called Safeguard in September 2022.

Instead, Safeguard blamed us saying the drain was clogged with leaves, and that is why we flooded. This was disproved by Roto-Rooter. The company refused to fix anything and did not respond to requests until I submitted a formal complaint on the BBB website exposing the breach of contract Have spent months (5) trying to come to an agreement we are comfortable with in order to have them out to fix the work. They do say they will repair the work for free, BUT… They tried to get us to waive their liability should the village fine us for the stormwater connection. There will be NO WARRANTY of this free work. So, if the concrete starts breaking a few months after the fix, they’re not liable. They claim they did not connect the drain incorrectly, and they are doing this fix to appease us (even though I have my contact that clearly states what was to be done, and a signed letter from the president stating that they did in fact do something else). As a result, we asked for a simple 1 year work and materials warranty just to ease our fears about something breaking in the future. Their response- WE WILL NOT ALTER THIS CONTRACT. Bob, John and Karen have been nothing but awful to work with. They are argumentative at best. The amount of times sarcasm and ALL CAPS have been used in emails by Karen, as well as the amount of times my husband has been screamed at over the phone or in person by Bob and John are immeasurable. As soon as you write them a check and they finish the work, they’re done. Even if they blatantly breach your contract (like with us), or the work is faulty, I believe they will not fix or stand by anything. They claim they have one of the strongest warranties in the business- I assure you this is a lie. If they do work and it never breaks, consider yourself lucky, because if something goes wrong they will not help you in any way shape or form to solve the problem, in my opinion. Instead, they will blame you as the customer and ignore you until you become too loud to ignore. Do yourself a favor, spend a little bit more money and go somewhere else that actually backs up their work and treats their consumers well. This is not that place. RUN AWAY.

FAQs for septic tank service projects in Diamond, IL
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.
