Get matched with top batt, rolled or reflective insulation install or upgrade pros in Parkville, MD

"I hired Koala Insulation of Greater Baltimore for attic insulation and fan installation. Initially, things went well. Jeffrey L. did a great job explaining insulation options and ventilation, and I chose the company for their fair pricing and strong reviews. Unfortunately, the project didn?t go as planned. A job quoted as one day stretched into four visits due to planning issues and the crew lacking a tall enough ladder. I also ended up with paint damage on my staircase from their hose, which required touch-up work. Jasper mentioned possible compensation for the delays, but I never received follow-up from him or the owner. The crews were polite and did good work overall, but the poor communication, unexpected delays, and lack of accountability were disappointing. I?m leaving 3 stars based on my experience."

"Great job on roof and insulation installs"

"We called Mister Insulation and Jeff came out in a day or so. We explained that we purchased new windows and doors and had insulation blowen into the walls but the house was still not warm. He took pictures in the attic and used a thermal camera to show where we were losing heat also we had mold. He removed the mold and replaced the insulation . He and his crew were very professional. We would recommend them ."

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

"The team was professional, worked quickly, and the install went smoothly. The only negative, which may not affect everyone, is when they went to open the knee walls to install the insulation. They did not cover any of my furniture or personal items. I have now spent the last week trying to clean all the dry wall dust off of and inside my electronics, clothes, walls, etc. This has truly been a nightmare. Additionally, the salesman said they would replace the drywall, tape and mud the seams, and I would only need to paint. Not totally true. One coat of mud is not sufficient and it's wet when they leave so they didn't sand it. A minimum of two coats with sanding in between and at the end is required which means I would have had to buy the supplies and do this myself or hire someone (63 yr old female and I had the supplies from a previous job and know how but didn't plan on it or want to). I'm more than two weeks later and still trying to finish this task between working and cleaning drywall dust. All other debris and materials were cleaned up to my full satisfaction. I would hire this company again and I do recommend them but make sure you yourself cover everything within range of falling dust and know the "only have to paint" is far from the truth. Good job otherwise and looking forward to the summer heat to test this investment."

"Thank you James Im, Antonio and crew for an amazing experience and a job well done! It is rare these days to find a home improvement company that you can trust from beginning to end. AHC staff and representatives ensured that every detail from estimates, to coordinating delivery of materials and quality control of installation was performed to the highest standards and exactly on time. James and Antonio/crew were attentive to our every question and concern, and in the end made the experience with AHC a memorable one worthy of the highest level recommendation. Bottom line: If you choose any other roof replacement contractor - you will be making a mistake!"

"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.

"I have an old house and new addition that was not insulated properly and a sun room that needed insulation. Dan was extremely knowledgeable on what needed to be done and his team did outstanding and professional work I highly recommend them! I wish I would have hired him first!"
