"Eric was quick to respond and to plan. He was friendly and easy to approach, fielded all of my questions during the assessment, and responded with the formal document in a timely fashion. He provided me with invaluable insight regarding the condition of my home's energy efficiency, was straightforward regarding what issues would provide the greatest return on investment, and immensely eased the triage of the many energy issues an old home has.

"In 2017, I contracted with them via Pepco because the 2nd floor rooms were hotter than the rest of the house, costing me greater A/C expenses. I worked with them on an energy audit to the upstairs bedrooms, removal of the acoustic ceiling tile in one room, addition/improvement of insulation, sealing in kneewalls, installation of new ceiling, insulation in the basement, and a follow-up energy audit. The auditor was very prompt and friendly but the workers didn't do an good job. The contractor was flaky. The HVAC crew were sloppy. The drywall installer/carpenter did a low-grade job by using low grade wood for the knee wall doors, and he set the ceiling inappropriately for house settling (now there are cracks between ceiling and walls). The energy audit following the work showed improvement but I'll need additional solutions to get the house to a more efficient state. I shared my disappointment with them and in 2018 they refinished cracking drywall ceiling without charge and replaced the doors - still not quality. They were bought by Minnick's, with whom in 2019 I scheduled an estimate for additional HVAC solutions for the upstairs. Minnick's jerked me around, never gave a complete estimate (I had to keep asking if it included what we discussed) and the estimate was exponentially more pricey than others and they proposed a solution that wouldn't solve the problem. I wouldn't recommend them at all."

I began working in the construction industry by my father’s side more than 20 ago. I had the privilege of learning from the regions best craftsmen... Professionals who took pride in their work and cared for their customers. My father worked with men that shared his impeccable standards, integrity and drive to do the job the right way every single time the FIRST time. While they taught me the trades, my father shared with me everything he could about business, instilling in me a strong work ethic and a set of core values that will never, ever change. I branched out on my own and opened ceccola construction 16 years ago. I believe our success continues year after year because of our integrity, craftsmanship, and my enthusiasm toward my work. It is very rewarding to me to know that my clients are so happy that they refer me to their friends and family over and over and over. Although the construction industry has changed quite a bit since I pounded my first nail, the way you should be treated has not. We have all the new gadgets, tools and materials, but most importantly, we will always treat you with respect and care.

"They did everything I wanted perfectly. All employees are experts and are very professional. Christian worked hard to give me the most beautiful deck possible at an affordable price. Justin has the best design skills I've known. They were mindful of the water source knob even thought I didn't ask them, and I am very grateful for it. I wholeheartedly recommend this company."

"Facts: contacted company to schedule service. Two weeks before electrician would arrive. Electricians arrived on time. Review electrical problems with technicians (two showed up). Left electricians to survey the home's electrical system. Met with electricians about current immediate problem. Agreed that the state of the system required someone specializing in old homes with legacy electrical wiring. Technicians informed me they had someone on staff who could survey the home and provide solutions to remedy the existing problem and possible overhaul of the system. They said they would escalate the problem to the appropriate person. I asked when is a reasonable time to wait before hearing back from the company. They said by the end of the week. I asked again how long to hear back - thinking that the end of the week was optimistic since it took them two weeks to get to the house. They said again by the end of the week. I waited until the following Wednesday and after not hearing anything from them left a review on the company website. Later that day a manager contacted me to discuss my review. NOT to discuss the possibility of getting someone out to the house but specifically the review. He stated a technician called me the day after the technicians were at the house. I have a smartphone they record ALL incoming and outgoing phone numbers. NO number from anyone I didn't know showed up in the phone log. NONE. And if he had called and received no answer NO one from the office bothered to follow up either by phone or by email or by text message. To the people at Oliver, welcome to the 21-century. How about using some the technology available to you for something besides swiping my credit card for the "arrival fee". DO NOT HIRE this company for ANYTHING! And BTW, another company I contacted for the same issue has sent me three text messages to follow up on the appointment that hasn't even happened yet. And I didn't have to wait two weeks to get on the schedule. Oliver, take a hint!"

Energy Efficiency Auditing questions, answered by experts

You can check your home's humidity in a few ways. A simple option is to use a hygrometer, which you can find at a hardware or big box store. Your smartphone may also have an app that can measure humidity. Modern thermostats, particularly smart thermostats, are also able to measure humidity levels.

The number one culprit of high energy bills is older appliances, especially fridges and freezers that are left on all the time. These two appliances tend to last a long time, which is good, but it also means that newer models are usually significantly more energy-efficient due to upgraded technology. The second most common reason for a high bill is heating and air conditioning.

There are energy-efficient options when building a cottage. Select green building materials, high-performance insulation, and energy-efficient windows when designing your cottage. Options such as solar panels, efficient HVAC systems, and LED lighting can lower your utility bills and reduce your environmental impact. Many builders offer energy-efficient upgrades as part of the design process.

Insulation is measured by R-value, which is the measure of a material's ability to resist heat transfer. The higher the number, the better the insulation. When installing insulation yourself, you need to determine the optimal R-value you need to keep your home warm in the wintertime, cool in the heat of summer, and energy-efficient all year long. Each inch of insulation provides between a 3 and an 8 R-value. The climate where you live plays a major role in what R-value you need and the price tag you might see in your insulation installation.

Electric bills tend to be lower in spring and fall because people use less electricity during these seasons. Milder temperatures allow for less use of heating and cooling, unlike during winter and summer, which usually bring more extreme temperatures.
