"The whole process was not pleasant. We went with Arrow because of the good reviews, but the insulation process was anything but easy. We have an older home that had nailed in dry wall. We decided to have the installation done through the home exterior in order to minimize clean up (we had a 3 month old at the time that we didnt want exposed to the dust/insulation particles). When the insulation was being blown in, many of our dry wall nails began to pop through the dry wall. We were never made aware of any of the potential problems with blowing in insulation through the home exterior, and this process created far more work than we were expecting. As for the exterior of our home, we were left with many siding boards damaged (which thankfully Arrow decided to pay for). Some of our siding could not get removed, and holes were instead cut into our siding. When these were initially patched, they looked awesome, but after only 1.5-2 months, the patch work began to show cracks, and now every hole that was created is visible from the street (some of the plugs have even been able to be moved around with very little pressure). This process has been a nightmare, and our home exterior, after almost 3 months, still is not what it was before the work was done."

Owner-operated. No subs. Cost is determined by the job. I am a residential designer/drafter. I am also a Green Build Design Specialist (Eco-Friendly), and a Residential Accessibilty Design Specialist (for handicap access)..

"Ray was very professional and punctual. Even though my project seemed small to start with, it had a few difficulties to work with. He coordinated well with the Structural Engineer to get things right and absorbed a lot of work to get the drawings done on time. He is very prompt on returning phone calls or e-mail messages and answered all my questions. He was pretty detailed in his drawings as well."

Energy Efficiency Auditing questions, answered by experts

Fans reduce peak cooling loads, lower air conditioning energy expenses by expediting heat exit, and enhance natural airflow throughout the home.

Smart glass doesn’t use a lot of electricity, and you can expect a standard window to add between $1 and $2 per year to your electric bills. Smart glass is proof that energy-efficient windows work. Although your smart windows may consume a little energy to operate, they can save enough energy to offset the costs. If you’re concerned about the minimal bump to your electricity consumption, you can opt for smart tint, which doesn’t require electricity to work.

Replacing a window frame will improve your home’s energy efficiency if the old frame is cracked or damaged in a way that allows unconditioned air from the outside into your living space or if you upgrade to a more energy-efficient window frame material. Aluminum is the least energy-efficient window frame material, followed by vinyl and wood. Fiberglass and composite frames are the most energy-efficient.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.

No, it isn’t necessary to have energy-efficient windows. However, if you care about your energy bill and making your windows more energy efficient, fixing any heat, UV, or air transfer issues is an excellent way to lower your bills and keep your house cooler in the summer and warmer in the winter.
