Hi I am Darryl Ames, Owner of Kacena Site Work Support Services, LLC. I have been doing Site work and septic systems for over 40 years. I used to own KIB Excavators, but due to the economy in 2008, I chose to sell my equipment and work for the guy I sold them to. Recently, I decided to go back out on my own, and see if I can help some people solve their septic and drainage issues. I believe in doing the job right the first time, giving the customer more than they expect, and try to do it at a reasonable price. "It's never wrong to do the right thing"

"Great price and great service!! Definitely would recommend Daryl to anyone looking for a company that communicates and committed!!!!"

"I was selling a 71 year old home and the inspection revealed a failing septic system. I had called another company as well as Bob snd had opted to use the other company which was local in Merrimack. Sadly I was told it would be 6 to 8 weeks. I could not wait that long since the house needed to be sold before winter. I called Bob and he began the same day! He explained he was also an engineer and could do the required septic design himself. He was able to have the entire job done in 2 weeks and we had a contract to sell before he finished. He was a delight to work with and I woukd recommend this company without any hesitation."

"Replaced leech field- he did an excellent job removing my old leech field and replacing it with a better system. From the time I entered the job in homeadvisor (approx 8am) I was called back before noon. We scheduled a site review later that day. From the time I selected Roadway, there was constant progress. Even when the permits were in progress, they were in constant contact to let me know what was going on. When the permits were in order, they worked nonstop until the job was done. Their work was excellent, prompt and neat. Highly recommend."

Fast and honest Quality Residential Electrical Service with 38 years of experience at only $75.00/hr. Also provide Commercial Electrical Service.

"Frances is pleasant to talk with and was punctual and responsive. My problem was that he's probably too busy. When I received his invoice, he charged me for the recessed lights that *I* had already purchased and then I had to prove myself by showing him the receipt. He charged me 2x the Home Depot price for Romex (which I had 100 feet of in my garage, ready to go). He put in dimmer switches that didn't match the coloring of my house project (old switches were almond, new switches should have been white) and then indicated he thought I wanted almond color since those were in other places (so were the white!). He should have asked what color I wanted, but didn't and then didn't offer to replace them. This experience left a bad taste in my mouth, I'd not hire him again."

Septic Tanks questions, answered by experts

Frozen well pipes make themselves known quickly, as your faucets slow down to a trickle or shut down completely. If you notice a serious reduction in flow in the winter from toilets, showers, kitchen faucets, and other plumbing fixtures, a frozen pipe or two is to blame. Another tell-tale sign is frost or ice on exposed pipes outside. 

Talking with a septic pro before planting trees near your tank is best to ensure the roots won’t interfere with your septic system. However, there is an easy way to figure out where to plant a tree—but you’ll need to know how tall it can get when it’s fully grown. For instance, if the tree can reach 50 feet, plant it at least 50 feet from your septic system.

The costs depend on whether you are buying into an existing well or starting from scratch. The average well drilling cost is between $25 and $60 per foot. The average cost to repair a well is between $350 and $1500. If you have a shared agreement and a community association, there will be additional legal and administrative fees. 

On average, septic systems last between 15 and 20 years. However, with proper care and routine septic maintenance, you may be able to extend your septic system’s life span to 30 years (or more). Some ways to keep your system in tip-top shape include scheduling a professional inspection every two to five years and reducing the flow of wastewater into your system.

Septic tanks are typically buried between four inches and four feet deep, depending on the property, the soil, and the size of the tank. When the septic tank is buried on the deeper end of this range, it may be harder for you to locate it on your own with a soil probe or just by observing the yard for signs of the tank. However, if you have trouble finding the septic tank, a pro will be happy to help you.
