Description of Work: Pascale, Brendan, and the entire team are fantastic, and I would recommend then to anyone and everyone. They performed our energy audit and insulation. Pascale fielded endless questions from me, and explained everything in the audit in excruciating detail. I really appreciated how knowledgable, available and patient she was. Brendan and his team executed the actual insulation in half a day. They were thorough and efficient and did a great job. Their work reduced our draftiness by 30%!!

Description of Work: Pascal and her team did an excellent job of insulating my townhouse. They arrived on time, a bit early , which is fine and worked very hard and were always professional during the course of the two day project. They even cleaned up after themselves and I would use them again. I would also recommend them to anyone that needs insulation done to their home.

Description of Work: Energy Efficiency Experts conducted a thorough energy inspection and assessment of my house, including assessment of points of leakage of heat and cold in and out of the house, existing appliances, and existing insulation, and made recommendations on how to address problems and reduce energy costs. The inspection included measurements of leakage and ventilation. All information provided was extremely detailed and helpful, and the inspection and assessment seemed very professional.

Description of Work: Energy Efficiency Experts (or "EEE" for short) performed 2 services which is why I did not list an approx cost. Also, I don't remember the actual cost and I don't recall at the moment where the receipt is. Suffice to say I believe that they are worth every penny I paid. | |I live in your standard cookie-cutter 70's hunk-o-junk house and during the winter this place leaks air like a Hummer guzzles gas. It got so bad last winter that the heat pump seemingly ran non stop and condenser unit froze into a block of ice a few times during the worst days. I finally signed up on Angie's List and searched for an Energy Auditor. That's how I found EEE. | |The audit | |Two employees from EEE showed up to perform the energy audit. They performed the blower door test and also inspected every nook and cranny of the house short of tearing up the floor and ripping siding off the house (which would not have been a bad thing since I hate the color of my siding). They took pictures for documentation. I also provided my most recent electric bill (I'm 100% electric, no gas) that luckily has a 12 month usage graph on it so they could compare my energy costs with others in my area. They also asked a lot of questions regarding the house, etc. After 2-3 hours they compiled a report and spent an hour going over the details with me, back-n-forth questions, and suggestions of where I could make the biggest impact on my house's efficiency. They also delivered the full report as a PDF to my email address. | |A few days later I met with Pascale who runs the company. She went over the details as well as supplied me with an itemized quote she has with specific contractors she uses. The total was around $5k for a very big laundry list of things to be done. Now I'm a fairly hard-core DIYer and could probably have knocked out most if not all of the list, but I don't have a spare 30 years on hand. Also, I don't mess with blown fiberglass insulation. | |The Work | |It was an all day project. The independent contractors were managed by Dave (I'm bad with names, I really hope it was "Dave") from EEE so I did not have to explain or direct anyone at all. VERY nice. They managed to complete a LOT of work with very little cleanup for me to do - I'm talking about minor vacuum sweeping because the reality is that no matter how careful you are, air will carry the occasional bit of dirt. I also noticed that they (Thankfully!!) closed our bedroom doors when working in the attic hatch located in the hallway. | |The Results | |I am seriously impressed - and I don't "seriously impress" easily. At the end of the contract work they re-ran the blower door test and we saw a 33% decrease in air flow from outside which dumped me right at the target air flow rate. I have been moving a thermometer around for days now taking my own readings and the house is clearly warmer. I set the temp at 70. The basement would normally hang around 56 which is insane considering there is no door to the basement - it's open air!! Now the basement is reading 65 on a COLD and WINDY day. I call that a "win". The main level previously sat around 67 and now shows a spot-on target temp of 70. The end-room on the main level had the worst insulation and sat around 64, but now reaches 70 with ease. I have not yet finished evaluating the top level. | |More important than temperature is that the house feels very comfy whereas before it felt like the wind went right through the walls. The heater does not run all the time now. In fact, it is not running more often than running now. | |Overall | |Thumbs up and a big LIKE for Energy Efficiency Experts! I'm sure you could find cheaper service - but you get what you pay for, and I am very happy with what I paid for. |

Description of Work: Energy Efficiency Experts did an energy audit of my house. Pascale provided a detailed report with recommendations. I also hired this company to perform the recommended work. The project manager was organized and efficient. Some work was not initially completed as scheduled because the subcontractor had concerns about removing and replaceing some siding. (The subcontractor otherwise did a fine job with insulating the attic.) Pascale immediately took steps to reschedule the siding work so that the job could be completed without undue delay.

Pascale showed up on time as promised and did a thorough audit of my house. It took her about an hour to set up and do the interior audit and blower door test. Then she walked me through my entire house and showed me directly where items needed fixing and what I could do myself and what someone should be called in for. After that, we walked around the exterior, basement, and attic where she reccomended additional improvement. She was very knowledgable and answered all my questions easily. The report came via e-mail two days later and detailed everything she had said in person, plus gave the improvements where I could get the greatest monetary return.

Very responsive to our inquiries re: the audit and was very flexible in setting up a time for the audit. The audit was very thorough but efficient and the representative explained all the results in terms we could understand. She also did on-the-spot improvements. Within a few days we also received a report that documented the results of the audit, provided a series of recommendations for what we could do to address the findings, and also provided names and contact of various companies/individuals that may be able to help us in addressing the weaknesses in our house. We had originally planned to replace all our windows to improve energy efficiency in our home, but based on the audit, this will not be necessary, and we can now focus our efforts and money on things that will result in more bang for our buck in terms of energy efficiency. We were very pleased with the quality of service provided.

It was a pleasant experience. We may get a repeat audit following remodelling.
Description of Work: Pascale performed a thorough energy audit for the home we were purchasing, and offered helpful suggestions. She found and pointed us to items even the home inspector did not have a clue about. Since Pascale completed her own home improvement projects helpful suggestions were offered on do-it-yourself items to save $$. Pascale referred us to Leonard Davis to inspect the oil burner that looked ancient. We used Leonard's services and that was extremely helpful. Word of mouth advertising works best after all!

When they did the audit, they found a a few serious problems on their audit, but nothing that could explain the incredibly high electricity bills. However, they also found that the meter had been blatantly misread the last month - and that might be why I had such a high electricity bill that month. They also provided an estimate for how much electricity I'm actually using. Based on that estimate, I've entered a formal complaint with Pepco to get my meter double-checked. Hopefully, Pepco will check my meter and admit that my electricity usage is being mismeasured, but I'll have to wait and see for that. If you get ridiculously high electricity bills, hire this company. Either they'll find something you're doing wrong, or they'll help you file a complaint with Pepco.
Description of Work: Since I bought my house, I have been getting extremely high electricity bills. I finally hit my limit when I got a bill of $370 for a spring month, when I was using no heating or AC, and I was even on vacation for 1/3rd of the month. I called the Efficiency Energy Audit on Wednesday morning and they were able to give me a full home inspection the next day. In the Audit, they checked my electricity consumption, gas consumption and water consumption. Most importantly, they found a leaking faucet outside that I might not have noticed for months.

Pascale appeared and acted professionally at all times. She worked steadily throughout our 3,000 sq. ft home for about 3 hours before providing a verbal summary of results and showing me data on her computer. A written report is to follow in a few days. She was thorough and detailed in her analysis of energy and fuel usage. Pascale's service was exactly what was expected. Though she had to move some furniture to allow inspections and mount equipment to take some meter readings, she left everything as she found it in our home. She seemed to appreciate our offer of decaffeinated hot tea. I was sufficiently impressed with her work that immediately invited Pascale to view my 7,000 sq. ft. office space to determine if an energy audit would be useful there as well. She spent a half hour looking around before determining "yes". Though she offered the home energy audit discounted price for Angie's List members, I declined because she spent added time at my office in another location and felt it very worthwhile.
Description of Work: Conducted a residential energy audit and made recommendations for ways to save energy without affecting functions or lifestyle.

I was very impressed from the start of our audit. I thought our appointment might be cancelled because of the ice storm the previous night. However, right at the time scheduled I saw Ms. Maslin walking up to our door with her equipment (she couldn't drive up our street due to the icing so she carried her stuff the last block). She was extremely professional in describing what she was going to do, set up her things and went through the house top to bottom, inside and out. After finishing she gave me a detailed briefing and then, within a week, provided the great report that I referred to above. One of the things that that was particularly helpful was the discussion of the difference between things that would cut energy costs and those that might not cut costs much but would have a big impact on our comfort. Throughout, she was extremely courteous and friendly. Since getting the report we have followed many of its suggestions and have seen a marked difference in our comfort and the ability of our furnace to keep up with the outside temperature.
Description of Work: We knew the energy efficiency of our house was poor since we have been quite cold this winter and the furnace never seemed to be able to keep up with the outside temperature. What we didn't know was what would help and what could be done at a reasonable cost. Among other things, the audit determined how badly our house leaked, where it leaked most, such as at the windows and the gap between our siding and brickwork, how much insulation we had and where it would be most effective to add insulation, and what other things could be done to improve our heating efficiency. But it didn't stop there. The audit examined the efficiency of our electrical appliances and lighting and our plumbing. The report that we got back was one of the most professional I have ever seen. It detailed everything that was found during the audit, what could/should be done ranging from the easiest and cheapest to more costly actions and it even provided possible suppliers and their websites/contact information for the materials and work we would need. It has been extremely valuable.

Clearly Pascale's professionalism positively influences her work. She was prompt, thorough as well as creative. Being a condo owner I was afraid there weren't many possible or inexpensive things I could do to make my unit more efficient. I came away with a long list of easy, inexpensive do-it-myself items, and feeling empowered to do them.
Description of Work: This was a home energy audit, not really a home inspection. On short notice (2 days) I set up an appointment and Pascale, the owner, came to my home to perform the audit. She arrived exactly when she said she would and spent several hours performing a thorough audit. She performed a blower test, checked windows, doors, fireplace and outlets(!) for leaks. Inspected all appliances including going up to the roof of my condo to look at the heat pump/air compressor. Together we did some minor repairs on the spot. Then she went over her notes with me in person and told me to expect a thorough, written report in the mail soon.

Terrific!!! From the first phone call until she left our house, Pascale was very patient with questions, and showed us all kinds of things about our home we never knew. She showed us what we could do ourselves and told us what things need a professional. We're not very handy so her showing us how to prepare our windows and doors for the winter was marvelous. Best of all was watching her deal with some of the quirks of our old house - things we would never have noticed or thought to address. Since they're specific to our home, a book wouldn't have helped. She explained everything slowly and patiently to two novices.
Description of Work: This was an energy audit, not a home inspection. 4 hours, the last hour and a half was beginning to knock out the low ticket items. Included blower door test, audit of the whole house including basement, attic and outside.

Trying to be more eco-friendly as well as save money on my energy bills in this time of rising energy costs, I was referred to Energy Efficiency Experts by a friend who had used them in the past and ended up saving around 30% on his utility bills. I was intrigued, gave them a call, and set up an appointment for a week later. Pascale Maslin, the owner of the company, actually performed the audit herself, with which I was very impressed. She arrived at my house on time with all the necessary tools. The audit took around 4-5 hours, and Pascale made a thorough inspection of all appliances associated with energy usage. Doors, windows, electronics, lighting, HVAC, hot water heater, dishwasher, toilets, washer and dryer, insulation, etc. She walked me through what could be done to increase my home's efficiency, and then installed weatherstripping on my doors at no additional charge. A week later, I received a report via email with all the things Pascale and I had discussed during the audit as well as short and long term strategies to make my home more energy efficient. I had a great experience, and really recommend Energy Efficiency Experts to you all.
Description of Work: Energy Efficiency Experts came to my home and performed a home energy audit. They inspected my home from attic to basement, identified energy inefficiencies, and made on the spot changes, like weatherstripping my doors, at no additional costs. I also received a personalized report with short and long term strategies for improving my home's energy efficiency.
