"Great! Job was complete .... removal of existing 50+ year old insulation, air sealing attic, baffle installation, installed 18 inches new fiberglass blown insulation, and new whole-house fan. Job started and completed as proposed. Crew on-time, quietly performed their work, and left spaces clean when done. Definitely worth the cost as noticeable improvement in second floor temperature and humidity readings."

These vents help your attic circulate air. With attics reaching over 120 degrees in the summer these are very important. They prevent mold and increase the lifetime of your insulation. Most other contractors miss installing these.
Look at the difference! Our foam is fire-rated which allows us to air seal around penetrations that contractors never could before.
Most homes have penetrations all over there attic. Imagine trying to blow up a balloon with a bunch of holes. It will never fill up. Now imagine trying to blow up your house with air conditioning and heating with a bunch of holes in the attic. It will never fill up.
Recessed can lights are notorious for leaking air. Recessed can light covers help with air-sealing your living space and prevent fires.

"My roof trim is in need of replacement to keep in HOA compliance. Diaz showed up with a free estimate and a more reasonable price than two other contractors who gave me a quote for the job. The work is on a three story townhouse, which is a high risk job and weather is a major matter for safety reason. There was a lot of delay due to weather and scheduling. Diaz was able to handle rescheduling via text and his guys were able to get the job done."

"This was the second time we hired ROI Construction LLC to work on our home and they did an excellent job both times. Originally our roof was replaced and ROI did a fantastic job, going above and beyond in making sure every detail was perfect. Recently we had the roof and skylights of an addition replaced. In both instances ROI charged less than the competitors and the workmanship was high grade. I highly recommend this company."

"Debbie, the AC&R salesperson, was very knowledgeable and confident. They were the 2nd quote I got for work and came in even lower than I expected (which gave me pause as a low bid is a red flag). But true to her word, they did the work professionally (mostly...see below) and promptly. While I had another company do the energy audit for the Pepco rebate, AC&R took over the work, did the blown fiberglass one day and the spray foam the next.



For the blown fiberglass in the attics above our additions, they added spray foam (from a can) around any gaps per the contract and foam board baffles at the soffits. The installer noted that all our soffits were blocked and the batting insulation was too wide for the rafter channels, so he leveled it out as best he could to ensure an even coating of blown insulation. At the end, he sealed up the gaps between the attic and our to-be-finished upstairs (cape cod style, so all one room).



For the spray foam insulation, the team came in the next day, and I had to be out of the house due to fumes. I did come back around noon as they expected to be done well before then. They didn't know I came in and I went to the back of the house to watch TV on my work break. The one annoyance was during their cleanup, one of the installers came down into our kitchen and then saw me. He said he was looking for a vacuum cleaner to clean the stairs. I told him don't worry about the carpet as it was getting pulled up, but this was the one piece of unprofessionalism I noted above. Contractors should NEVER use the homeowner's property; they should bring their own tools, including vacuums!



While the spray foam can get very messy, they kept the splatter mostly contained to inside the crawlspace, not the finished flooring. However, I was surprised that they didn't tape off the outlet covers or light switched. since the particles are so small, we're going to have to replace the switches/receptacles at our cost. Also, there was a storm door screen that wasn't covered and now needs cleaned. Basically, I think they should have taken more care in covering the very few items we left upstairs and the outlets/switches.



They didn't spray around the window frames (large gaps where window weights used to be) because the open cell foam would expand too much. If I wasn't there, I think they would have just left, but it was clear in our contract discussions they needed to insulate those spaces too. They used a few cans of "Good Stuff" equivalent, but didn't fill in the gaps entirely. It did the job well enough, but it's a ding against them as I expected more preparation.



Lastly, I thought that AC&R would walk me through all the scheduling and final "test out" (for the Pepco rebate), but I had to contact them and schedule with someone different each time. They were always prompt, but I expect the experts to know to do this for/with me rather than expect me to know the process. I go through it once in a lifetime while they do it weekly.



While the end of the review sounds more negative than positive, I would definitely recommend AC&R out to others as they're priced right, they have been in business for over a century, and like any contractor, you just need to follow up to be sure everything is done to your satisfaction.

"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."

"AHC, Inc did a very thorough job walking our roof and finding areas that required caulking; replacing loose nails and shingles. The technician Austin Bunnell, as a total courtesy, removed the base to an old satellite dish that was never taken down.. He then caulked that area for us. Great customer service was provided and care taken to respect the household (protective face mask and shoe covers were worn). A very good value at $149.00"

"Person who visited was very polite and noted that what I purchased was likely not something that would meet my expectations.  I wanted an energy audit, how my systems could be improved in home, lighting, heating, insulation and air conditioners.  What I got was a list of things they could work on and the price to do that work.  The work list in no way was considered an energy audit, rather it was a punch list of things I could do based on their visual inspection.  I did not have a comparison of work and benefit/savings calculation.  There was no checklist of inefficiencies and how that translated into energy losses. For example, multiple hi hat lights in house, they spoke about boxing and insulating a few, less than 10, when I have almost 90 in house.  Overall I was disappointed, the tech who came said the offering needed to be better presented prior to start of work."

"The person arrived on time to evaluate our home for the written estimate.   He was very professional and easy to talk with.  We talked at length what I expected.   In addition, he was very knowledgeable.   The estimate was sent by e-mail with in one week.  
The work took several days.   The men arrived on time and were very curtious.   All materials were picked up and my yard was left intact every day.   I did not find any debris or nails in my yard after the job was completed. 
They asked permission to leave a generator and ladder overnight on my property.  Very respectful.
At the time of the initial estimate I said that wanted all wood trim replaced with Azac.   All trim was replaced with Azac, as I requested.
The roof and railings look great!
My neighbor has used this company for more than 15 years and he only has positive comments about their work and the integrity of the company.  I can now agree with him.
I have more exterior work to be done and I plan to use this company again.

Insulation questions, answered by experts

The most obvious con of injection foam is the cost. It’s much more expensive to install than fiberglass or spray foam, but it may be your only option (unless you want to remove entire walls around the home). Another con is that it involves drilling into existing material, which has to be repaired after the foam is injected. Some injection foams are made from products that aren’t environmentally friendly, and improper installation can lead to trapped moisture, which can lead to expensive mold remediation down the road. 

The most affordable way to insulate a garage involves choosing cost-effective materials like fiberglass, which comes in batts or rolls and is relatively easy to install. You can often install this type of insulation without needing to add drywall, which helps reduce costs. While a DIY approach might seem cheapest, hiring a professional installer can be highly cost-effective. Experts can accurately determine your garage's specific insulation needs and ensure the best results for your investment, often using batt insulation for the bulk of the project.

Installing insulation helps reduce energy usage, improve home comfort, and lower utility bills by maintaining stable indoor temperatures year-round.

Yes, insulating ductwork in a crawl space is a worthwhile investment, especially if you live in a colder climate or run your air conditioning for most of the year. Uninsulated ducts can lose up to 30% of their heating and cooling efficiency, which can significantly impact your electricity bill. The project is a relatively small investment and typically only takes a few hours. It's a particularly simple add-on if you are already hiring someone to insulate the entire crawl space. An added benefit is that insulated ducts put off less hot or cold air, making them less attractive to pests.

Yes, you should insulate behind shower walls. Insulating helps prevent heat loss, which keeps the shower or tub from getting too cold and helps maintain a comfortable temperature in your bathroom. Additionally, proper insulation and air sealing can help prevent wall rot and moisture buildup. It is recommended to use a high R-value rated foam insulation combined with a vapor barrier.
