"Ducts were sealed quite dramatically from the graph they provided. I am not seeing much savings on heating as I expected."

"There was a problem initially with the radiant barrier installation - the first crew of two were installing 30" wide rolls lengthwise along the roof end to end instead of from ridge to eave as the manufacturer recommends and made a couple of other minor mistakes which were easily corrected. After talking to the manufacturer, the sales rep offered to take out what had been installed and re-install according to spec or continue as already done with sealing of all seams and a discount on the job. Done this way, the foil would not have the insulation properties per spec but would provide the radiant barrier I desired. I chose the letter option and the barrier work was continued by another crew on the 2nd day. On the 3rd day the crew finished up with the barrier then blew in the installation.
With the exception of the initial problem, the work was done neatly and professionally by courteous workmen who cleaned up completely after the job was done.

"The work that Metro Insulation, LLC did was well done. The contractor was very kind. I was a new member of Angie's List at that time. I didn't really understand so much what the big deal was. It wasn't a very large break in the price, but it wasn't a tremendous amount of money so I was glad we did this. I would recommend the company. The insulation they installed did end up making our house warmer. The price was considerably more than what I expected it to be, but I really wanted to get this done so I didn't comparison shop. I would shop around more before making a decision whether I would use them again."

"i scheduled an appointment to get 3 missing shingles replaced. i saw the $149 deal that included a full roof inspection, replacement of up to 5 shingles, attic inspection and a few other maintenance tasks along with a $250 credit for future use. i really only needed the shingles replaced but i'm glad i purchased this deal. Howard (one of their head techs) arrived right on time for the scheduled appointment. first thing he inspected was my attic. he found a few issues and described them fully to me along with showing me pictures. he noticed one of my air ducts was not connected, which meant i was heating and cooling my attic for who knows how long and also meant my bedroom was not getting the right air supply either. to save me time in having to hire an HVAC specialist, Howard asked me for a roll of duct tape and was able to reconnect the dislodged air duct. he then spotted a leak in the roof about the size of a quarter that was dripping through the insulation. he also saw water marks in another location but wasn't quite sure how it got there. after he inspected the attic, he hopped up on the roof. he replaced the 3 missing shingles (didn't match my current shingle color but no big deal). he also found where the leak was coming from. apparently there was a bullet casing stuck in the roof which was causing the leak! after his work was complete, he gave me a full description of what he saw and a few recommendations. he answered any questions that i had. Overall, Howard seemed like he had a lot of experience and was honest. total time of the work took about 2 hrs 15 minutes from start to finish. i would use them again in the future for any roofing needs. he told me they do other work like windows and siding. my only negative was that my appointment date was about 1 month from when i called to schedule it. i'm guessing it's because they are busy and booked up but it was obvious after the quality of service that was provided. also, the pictures he took were supposed to be sent to me. it's been about 5 days now since service and i have not received them yet."

"They pointed out areas of air loss that needed to be covered or blocked and advised more attic insulation which service they will provide. Their price offer seems reasonable. I'm still crunching numbers.

"Overall it went well except I didn't get the other estimates I requested for insulation and gutters. This was not the low bid but they have done several cedar roofs in the area and have a good reputation. The end result looks really good.

"We have the BGE Home protection program, so we have them come out in Fall to do a check-up on the heating system, and in the Spring to check-up on the A/C. They are always prompt, pleasant and professional. In the past we have had them repair the system and we area always happy with their work. The protection plan is well worth it - we had a water heater die and it was great that we could call BGE and have the problem fixed without having to pay thousands of dollars.

"We had a horrendous situation with a basement floor installation that went wrong leaving our house full of fumes, and a week later we discovered our basement was contaminated by asbestos in the process. When we called Bill and Contractors Unlimited, they were extremely responsive. Although other companies gave us bids, Bill was able to work his schedule to fit us in weeks sooner than the others. Although the cost was a bit more, that saved us money because we were displaced and could not even go into our house because of the fumes. CU set up negative air machines to replace the air, they followed asbestos abatement laws, they cleaned every item that could be salvaged in our house. They even saved more than we thought which really reduced our overall expense. Bill and his team were extremely professional, friendly, helpful, and really went out of their way to ease our stress from this situation. At the end of their process, Bill arranged for a air quality inspection which we happily passed - able to return home. I would gladly recommend Contractors Unlimited for asbestos abatement. I just wish we had called them before the floor guys created such a disaster. Thank you Bill!

When choosing a professional insulation installer, consider asking these questions to determine the best fit.
Will you address air leaks in my house?
Can you provide an R-value (heat resistance) fact sheet?
What kind of insulation will work best for my home?
How do you handle signs of a water leak?
Are you licensed and insured?
Can you provide customer references?
The best type of insulation for your home depends on what you need, so the answer will depend on your specific situation. If you’re building a house, structural panels are easy to install during the building process in addition to being the most energy efficient type. If you live in a warm climate, reflective insulation may benefit you more as it costs less than other insulation types. And for standard attics, loose-fill, spray foam, or blown-in insulation work well.
If you plan to heat or cool your garage, you’ll need to insulate the garage ceiling. Insulating your garage ceiling will make your garage much more energy efficient and save on heating and cooling costs. Not only does insulation make your garage more energy efficient, it helps reduce noise and can extend the life of your garage roof. You can use fiberglass, cellulose, mineral wool, or spray foam insulation for this project.
In some cases, you may not have enough insulation to properly regulate your home’s temperature. Watch for a few signs your home needs more insulation, such as:
High heating and cooling bills
Uncomfortable room temperatures
Ice dams on the edge of your roof
Roof leaks
Cold floors and walls
Freezing pipes
Temperature fluctuations
Visibly low insulation
Noise problems
Pest problems
On average, insulating an attic costs about $2,500, ranging from $1,500 to $3,500, depending on the insulation type, amount, and your attic’s accessibility. Additional cost factors include sealing air leaks, removal or replacement of insulation, and inspections. Types of insulation include:
Blown-in: $1–$4 per square foot
Spray foam: $2–$5 per square foot
Batt: $2–$4 per square foot
Structural insulated panels: $4–$7 per square foot
Loose-fill: $2–$5 per square foot
Reflective: $0.50–$1.50 per square foot
