"Maine septics put in a system for one of my clients, and they did a fantastic job. Everyone else we talked to quoted us much higher, or couldn’t get it done for months. These guys get it done!"

"The price was a little expensive, but it was worth every penny. I chose the package with additional add on’s, because I wanted a comprehensive report. Tom was very thorough, professional, and knowledgeable. They saved me a ton of money by finding an issue with the septic system, that wasn’t easy to find. Tom was there for close to 4 hours and went over every aspect of the home with me in a walk through. I would highly recommend Main Choice and will definitely use them again in the future. Bill the owner was a very pleasant guy as well, and wasn’t afraid to roll his sleeves up and get dirty. Couldn’t have been happier with their services."

"We were very fortunate that they were able to come quickly and replace our nonfunctioning septic pump promptly. They were professional and easy to communicate with. Given the emergency nature of the project, we did not get other bids so we can't say whether the price was reasonable, but they were upfront about the cost and stuck to their original estimate."

"Tony and his crew installed a drainage system in my backyard. They showed up on time and did what they said they would do leaving my yard clean and seeded. Tony even salvaged some granite and we repurposed it as a stepping stone walkway at no extra charge. I have no complaints. I have not had a chance to see how the drainage system works yet but will alter my review if necessary. As of now I would recommend White Rock to anyone who asks who did my work."

"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."

FAQs for septic system installation and replacement projects in Cornish, ME

Most septic system replacements require several days to complete, not including permitting and preparation time. The process begins with site assessment and testing, followed by excavation, component installation, and final inspection. Weather conditions, property accessibility, and inspection schedules can all affect your project timeline. Your contractor can provide a more specific estimate based on your property's unique characteristics.

Standard homeowners' insurance policies don't cover septic system replacement due to age or normal deterioration. Coverage may apply if damage results from specific covered events, but routine maintenance and eventual replacement are generally considered homeowner responsibilities. Review your policy details or speak with your insurance agent to understand your specific coverage limitations.

Look for multiple indicators such as slow-draining fixtures, unusual gurgling sounds in plumbing, sewage odors inside or outside your home, or wet spots in your yard. Unusually lush grass over the drain field area, frequent backups, or recurring repair needs might signal system failure. Addressing these warning signs promptly can prevent property damage and health hazards.

DIY septic installation is not recommended and may violate local regulations. Professional installation ensures compliance with health codes, proper design for your specific site conditions, and appropriate safety measures. The specialized equipment, technical knowledge, and permitting requirements make this a job best left to licensed professionals who can guarantee the system's safety and effectiveness.

With proper maintenance, including regular pumping, a drain field lasts 20 years. Various factors influence system longevity, including household size, water usage patterns, and soil conditions. Regular professional inspections can help determine when replacement becomes necessary. If your system requires increasingly frequent repairs, replacement might be more economical than continuing to address individual problems.
