Established in 1982, Lloyd's Electric Service has grown into one of the top electrical contractor companies in the region. Our company offers residential, commercial and industrial electric services, alternative energy solutions, preventative maintenance, and fiber optics installations. Our commitment to our customers and community is apparent through our efficient and high quality work. During our storied history,we have become experienced in a broad range of markets.

"I was told that charges would begin when they left their shop and would end at the completion of the job. Sadly, I was charged for a trip to and from, neither of which was in the proposal. In speaking to other electrical companies as well as my own 45 years of experience as a home improvement contractor, installing a couple of bath exhaust fans is clearly a one man job, and should've cost around $350 - $400 total. However I found upon their arrival that the company policy is to send 2 men per job whatever the job. I provided a ladder for easy access to the hugely open attic and then proceeded to observe the next 3 hours one man doing 95% of the work as the other basically watched. No problem... accept that I was being charged $70 per hour per man and then told by the rude and unreasonable office personnel, Victor, that he was informed by the techs that I probably would be unhappy with the high charges. Being charged a $280 trip charge as well as $70 per hr. for a "gopher" is pretty excessive. I would never recommend Lloyd's Electric to anyone and am sorry I had to experience using them even once. They did say they enjoyed my wife's fresh German chocolate cake as well as the remainder roll of my "special" tape they took!"

Septic Tanks questions, answered by experts

Septic distribution boxes, also called D-boxes, tend to last over 30 years if taken care of extremely well. In most cases, however, they tend to last anywhere from 15 years to 40 years. Regular cleaning and maintenance, as well as living in an area that doesn’t flood the tank or the system regularly, will all have an impact on the lifespan of the box.

With proper maintenance, most types of septic systems—including mound, evapotranspiration, and constructed wetland systems—can last up to 40 years. To keep your system running as long as possible, follow basic septic tank upkeep guidelines, like pumping your septic tank every three to five years and only flushing human waste and toilet paper.

Ideally, you should conduct a mechanical inspection and a bacterial or well water inspection yearly. While you might be able to push it off to every other year, it’s best to have peace of mind, especially when it comes to something that you use so frequently. 

If you experience repeated gastrointestinal illness in the household, it's important to test the well water more regularly for quality and cleanliness to check for bacteria.

Well water is often assumed to be hard because of its high mineral content. Hard water can lead to mineral build-up in your pipes and appliances. You can manage hard water by installing a whole-house filter system. These systems can help extend the life of your water-reliant appliances like your hot water tank and dishwasher. 

Modern septic tanks have two lids: one that covers the inlet where wastewater flows into the tank and one that covers the outlet where the treated water flows out to the drain field. However, older septic tanks installed before 1975 may have only one lid. Because septic tanks last 20 to 40 years, if yours only has one lid, it may be time for a replacement.
