They guided me through every step of the process and helped me obtain all the required documentation for the rebate program, including the city permit. The permit process went incredibly smoothly, thanks to their expertise. Daniel was professional, knowledgeable, and very easy to work with. The pricing was also extremely competitive compared to other companies I consulted. The installation itself went just as smoothly--they were efficient, respectful of my home, and made sure everything was cleaned up afterward.

I asked for a rough estimate online without an inspection for a typical 1100 square foot house…read more They told me it it was illegal for them to give a rough estimate without an in person inspection because they are licensed. A few of the places I checked with didn't want to give a rough estimate, but none of the them lied about their reasoning, so they didn't get reviews. Some even gave me a rough estimate right here on yelp. Based on some of the other reviews, it seems like this sort of pressured sales approach is their business model, instead of helpful answers and good work.

This was the lowest bidder by maybe 10% and did OK work, but I had to check their work then request…read morecorrections, and they were unclear on scope options so I was left with unsealed fixtures and fiberglass debris in the house to clean up myself. While they did work with me, did exceed expectations in rodent proofing patch support, and were quite friendly and ready to correct most shortcomings I pointed out, I would have preferred they not rely on my oversight to give quality work consistent with my original direction. They did not tape off a sealed plastic tunnel from the front door to the attic, did not let me know sealing off light fixtures was excluded, left some spotty gaps between batts of insulation and between batts and joists and did not run a second layer of insulation where I had requested it perpendicular to the first layer to better air seal joist gaps. They were unclear about IC-rated lights in contact with fiberglass batting insulation and its fire risk and did not seem to know the code on attic ventilation requirements enough to answer questions fans or vent sufficiency. Granted, I did not have insulation removal as part of the scope, it was already done by a prior contractor during rodent proofing. Instead of making a tunnel, they taped off a small space from the attic hatch to the floor and put construction paper down on the floor. This helped with scuffs to the floor and may have contained some of the fiberglass dust/particles, but did not protect from scuffs on the wall or contain the fiberglass during transit to the door that was shed from the new batts being carried in or from their clothes and shoes, even though they generally had only one person trafficking the batts up to the hatch. They bagged up debris in the attic and carried batts in bags in from the door. They removed all the paper and plastic before I was done with my inspection, an inspection that yielded more work required, then they didn't put protection back for the short time of rework. The foot traffic left some fiberglass flakes and particles strewn about the floor. It took me two hours of cleanup to get that debris fully clean so my baby could crawl on the floor again. I vacuumed with a shop vac, made three passes with a swifter dry duster, and vacuumed with a house vac. I suggest asking them during the bid stage about the following, getting a quote for that work (with optional line items if you don't need everything), and confirming it is written in the proposal/bid/work order scope before awarding the project: - a sealed tunnel for transport of removal and installation - cleanup with vacuums and swiffer after until no particles remain in house on floors or touch surfaces - air-sealing fixtures and other gaps from rooms below - code and safety insulation contact with fixtures and blocking with gaps (2"-3"?) to avoid contact - insulation contact with rafters/roof battens/sheathing - roof ventilation adequacy and fan install if needed - gap prevention - running a second layer of batts perpendicular to the base layer for better air sealing - minor or major rodent proofing gap sealing with mesh and foam This is a good list to consider for any contractor you use, some contractors may find this obvious or already include it, but you could still benefit from knowing what to check for and avoiding change orders. I ultimately was satisfied by the work and they made some corrections and concessions to balance the expectations vs delivered result, but would have been happier with more clarity of scope options (too late to seal the fixtures now unless I pay $600 more or do it myself) and I had to do lots of cleanup that I could have avoided if I simply rejected their suggested home debits containment method of bagging with no tunnel. Although I would not suggest this crew if you are not prepared to check their work, which not everyone is physically capable of doing in tight spaces of some attics.

Since Jonathan and Ralph already had their equipment on-site, they offered him an amazing price too and got his house done the same day--two houses in one shot! Their professionalism and quality of work are on a completely different level. I 100% recommend this company to anyone looking for insulation.

Having a group of workers in your attic can be nerve-racking, but these guys were professional, respectful, and great to work with from start to finish. My attic was in terrible shape--old 60-year-old insulation, trash, nails, wood chips, and even a nasty rodent odor. The team completely cleaned everything out and thoroughly sanitized the entire space. They truly went the extra mile by sealing every opening with foam and wire mesh to help prevent any future rodent issues. The new R-38 batt insulation was installed cleanly and correctly, and you can tell they take pride in their work. I originally chose 911 Attic because their pricing was competitive and their Yelp reviews were excellent--and they absolutely lived up to those reviews.

Five or ten minutes after reaching out to Advantage Air on Yelp, a staff member from the company (Brenda) contacted me to follow-up and schedule an appointment. She was amazing! On the day of our appointment, the technician arrived on time. In fact, Brenda contacted me beforehand to advise that he was running ahead of schedule so he could be at our home 30 minutes earlier if we were available. We were ready for him so it worked out fine. The repair technician (Joe) arrived and introduced himself. Initially, I had a question about a message displayed on our thermostat, what it meant and if it had anything to do with our AC unit not operating. His response was perfect. He explained everything in Layman's Terms and I appreciated that very much. After inspecting our AC/Heating Unit, Joe determined there were three parts that required replacement; the contactor; the capacitor; and hard start kit. He had some of the parts with him but had to leave to retrieve other parts off-site. He left but promptly returned in about 20-30 minutes, installed the parts and tested everything. Our AC unit has been working great since then and we are so pleased that we found and hired Advantage Air to make the repairs on our air conditioning unit. Thank you Brenda and Joe!!!! Best customer service ever!

The insulation in my crawlspace under the house was consistently wet and after getting plumber to…read morecome out to confirm there's no pipe leak, I decided to ask ChatGPT, it told me that prolonged wet insulation will create problems long time and that I should install something like a vapor barrier. I found insulation labs and Ray came out for an estimate. He told me the same thing as ChatGPT did so it confirmed my suspicions. His quote was definitely on the expensive side compare to a competitors quote but he did mention that his quote is expensive because they use 12mm thick vapor barriers which is more resistant. The other competitor quoted me around half the price but for 6mm barriers. I again asked ChatGPT and it told me that 12mm is preferred because 6mm is prone to breaking once a contractor or someone go down to the crawlspace and when that happens it loses its purpose to control vapor. As a result I went with insulations labs and they spent a day putting it in. So far I haven't seen any issues and I believe they have done a good job from the pictures they shared
