Franklin's Septic has been in business since 1979. We offer complete septic care. Check us out on the bbb.org website today. Call us today for a great deal!

"I contacted Mr. Franklin for what I thought was regular maintenance. I had never had the septic pumped before and was unsure where the tank was located as there were no visible indication of the piping. Mr. Franklin poked around but could not locate the piping so he contacted the County Health Department and obtained a copy of the blue print outlining the location of the septic tank. Turns out the line was inactive and the tank did not need to be pumped. After all the trouble Mr. Franklin went through between the drive out here, the hour he spent poking around trying to find the septic tank and waiting for the county to call back, he refused to accept any money from me. He would not even accept a trip charge. In a world were honesty just doesn't seem to exist anymore, it is so good to know that there are still trustworthy businesses out there! Mr. Franklin's knowledge of what to look for toppled with the time he took just to educate me is just priceless! I wish all businesses was like Franklin Septic!"

"We needed a full renovation of our bathroom in order to accommodate my wife who is physically handicapped and is unable to navigate over ANY barrier in the bathroom. I needed a bathroom that met her needs AND was designed appropriately for use by non-handicapped visitors. Charles from Charles Home Improvement came to the house and truly listened to my somewhat complex needs including a bathroom with no curbs, no shower doors, or walls. After meeting with him he gave me a bid which was most reasonable. The staff he hired to do the floor and wall tile, plumbing, counter tops, cabinets, and doors were very professional. The work was top quality. I enjoyed watching them work each day to accomplish the vision my wife and I had. With GREAT effort they completed the work ON TIME and ON BUDGET! A bathroom that is bright, modern, and completely ADA compliant .... and a bathroom that looks great! Charles Home Improvement is a wonderful company with great people. Without reservation I can give Charles Home Improvement my highest recommendation. Bruce W."

"On 3-4 November 2025 Chris, Corey and Xzavier encapsulated my crawlspace and set up the dehumidifier for the electrician. Keep in mind, the crawlspace varied from about four feet to two feet. At two feet they were crawling on their bellies. The three arrived at my house on time, Chris explained exactly what was to be done and the three of them completed the job in a most professional manner. I inspected the crawlspace when the job was completed and was amazed at the workmanship that was done. I commend Chris, Corey and Xzavier for their excellent work and the courtesy shown to my wife, myself and even our dog, Zoe. Thank you, Chris, Corey and Xzavier for a job well done. "

Install Boiler questions, answered by experts

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

Costs depend on issue severity, parts needed, and labor rates.

It is almost always more affordable to repair a radiator than it is to replace one. The average radiator repair cost is around $150, and it’s typically about ten times as expensive—around $1,500—to replace a radiator. A repair usually takes under an hour, too, while a replacement can take several hours, making it less of a time commitment to repair one.

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system. 

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.

Overall, heating your home with an oil furnace tends to be less expensive than heating your home with an electric heating system. Oil heating systems stay warm for longer periods of time without drawing a constant electrical current to maintain a temperature. Plus, heating oil systems typically have a longer lifespan and lower price tag than their electrical counterparts, resulting in short- and long-term savings.
