"Avoid this company at all costs. I hired them in Sept 2024 to replace oil tanks, and while they arrived on time, the installation was reckless?they cut through two floor joists instead of properly routing the fill line, compromising my home's structural integrity. They dismissed my concerns and promised a repair that never happened. Even if they had, it would only matter if it passed a home inspection. I?m now facing costly repairs, zero accountability, and the worst service I?ve ever experienced. Don't let Sal or his crew near your home."

It's true: A fuel tank will eventually corrode and leak. If you encounter a tank that is more than 15 years old, there is a good chance that substantial corrosion has taken place. Trust that Sterling will remove your tank with the utmost care for your property and will create a safe environment for your family. Call Sterling Environmental Services today!

"Sterlington Environmental removed my "ready to leak" 60 year old in-basement oil tank and replaced it with a clean, modern Roth tank in about half a day. This is an inherently messy job and they did it quickly and efficiently while paying attention to the rest of my home. The entrance to my basement is through the house and they laid down protective materials to protect my floors and were very careful not to damage anything or spill oil as they worked and moved materials, tools and supplies in and out of the basement. They also handled all the permitting and inspections. I hope to never have to do this again, but if I do, I will call Sterling to do the job. "

"I had an outstanding experience working with Zach and Breaking Ground Earthworks! Zach handled a big job for us—removing old retaining walls, regrading the slope of our yard, prepping the area for new landscaping, and replacing an outdated drainage system. He also took care of a few stubborn stumps left behind from previous tree removals. His work was not only thorough and precise, but he was also professional, efficient, and clearly very experienced. The site was always left clean and organized, and communication throughout the project was excellent. I was impressed with the transformation and the quality of Zach’s work. Highly recommend him for any excavation or site prep needs—you’ll be in great hands!"

Our distinction is the quality of service we bring to our customers. Accurate knowledge of our trade combined with ability is what makes us true professionals. Above all, we are watchful of our customers' interests, and make their concerns the basis of our business.

"Conti Landscaping did an amazing job from start to finish. I was contacted almost immediately after putting in my request for the sod installation for my front yard and Chris came out to take a look the next day. His pricing was very fair compared to some other landscapers in the area, and he was able to do the work within a week of us meeting. He was very communicative as to how he wanted to complete the project and what days he was available to do so. Chris and his team showed up on time both days to complete the sod installation at my home and it looks great. Everyone was kind, knowledgeable, and did a great job. I would absolutely hire Conti Landscaping again for any future needs at my home!"

"I hired Art to help level out my backyard, and unfortunately, I had a really disappointing experience. He started the job but left it incomplete and in worse shape than when he began. The yard was left uneven and messy, with piles of dirt scattered around and no clear plan for finishing. Communication was poor throughout, and despite several follow-ups, he never returned to complete the work. I regret hiring him and wouldn?t recommend his services to anyone looking for a reliable or thorough job. "

Excavating questions, answered by experts

Chipmunks dig their burrows about three feet deep and up to 30 feet long. The entrances can be two inches wide or more. Chipmunks are fiercely protective of their burrows and use them to protect the nuts and seeds they gather for the long winters.

The cost to repair a crawl space runs between $1,500 and $15,000, depending on the extent of the damage. Major flooding or water repairs can cost up to $10,000 for removal and repairs. If you simply need to clean your crawl space, expect to pay between $2,000 and $6,000 for a major cleanout. Replacing a crawl space beam due to rot or damage can cost between $1,500 and $5,000, while removing and replacing damaged insulation costs between $1,000 and $4,000.

Professionals who complete perc tests can usually do them in a single day. Including excavating to expose the test site, filling the hole with water, and monitoring it while it drains, you can expect the test to take between four and eight hours total. It’s possible that you’ll get the results the same day, but some companies may take a few days to get official results.

It is a common belief that excavation is easier or less costly when done in the summer or when the ground is not frozen. Seasons have little effect on when excavation can occur; however, inclement weather can prolong the duration of the job and potentially increase costs. For this reason, those in rainy climates may opt for seasons with milder weather.

There are many ways to cut through roots when digging, especially if your trencher doesn’t seem to be removing the roots. First, use a shovel to expose the roots. Then, use gardening shears to clear out smaller roots or a reciprocating saw to remove larger plant roots. If you plan on keeping the plant, avoid cutting any roots over 2 inches thick.
