We hired Karl and his team to put in some additional insulation in our attic space. Karl provided a detailed quote and a range of options for us to consider. His team was professional and completed the work quickly and efficiently. It didn't even take a day to feel the difference in our living and dining room area. I would highly recommend Capital Insulation! read more

Excellent work! Capital Insulation came and did a "tune up" bringing a 40 year old R9 attic insulation to energy efficient R49. A very professional job, they left the place cleaner than when they started. Very impressed and affordable. read more

Thank you for your good work. Carl and his crew were on time and honest -- yes, you read that right. The insulation crew had to stop work for another problem in the attic and I appreciated being alerted to the problem that wasn't in their scope. I was able to get the other problem fixed in a few days and the insulation crew got right back to work and finished as scheduled. The office was a pleasure to work with. You should call other contractors for estimates as you always should but take this as the highest recommendation for Capital to make your final selection. read more

Capital Insulation (CI), headed by Karl Strandberg, provided blown-in fiberglass, drilled ventilation holes, attached bathroom air-vent exhaust tubing, and added baffling for much less than other contractors, including HomeDepot, to just blow-in fiberglass. CI's Karl S. showed up on time and completed the work promptly. Karl was great; however, his side kick mostly chatted on his mobile, so given the choice make sure your contract mandates Karl do the work. read more

Great job today by Karl and his team. They came in and insulated my attic in about 2 hours. My home, built in 1969, had about 3-6 inches of insulation. By the time they left, we had about 18" of blown insulation along with new soffit vents and an insulated attic access door. Great job overall!!! Can't wait to finally enjoy sleeping in a "cool" room!! read more

I had great difficulty in dealing with this company. They showed disinterest in my job possibly because it was smaller than they preferred and no showed twice after their representative made appointments with me on two different days. She called to cancel only after substantial inconvenience waiting. Hard to communicate with them. I also have unresolved questions about their bid. read more

I agree with other reviews. Karl and his partner did a good job by adding insulation to our awkward and tight attic. They were punctual and professional. One week after the blown-in insulation being in place, I can feel the house is retaining heat much better and is more comfortable. More notable difference is the second floor. It is no longer an ice box. I am happy with the decision to go with Karl. I even recommended Karl to our neighbor. read more

We had a wonderful experience with Karl! During the initial consultation, he was on time and provided recommendations but was not pushy - which was much appreciated. He did a great job communicating what needed to be completed and was kind and courteous during the job. read more

Capital insulation did a great job fixing our poorly insulated attic. They were not the cheapest offer we had but we chose them as we thought we'll have the best quality work. Karl was the only contractor who actually went into the attic and did a through look around when he arrived for our free consultation. The others spent only a few minutes by gazing from the attic door. That played a big role why we decided to go with Capital Insulation. They take their business seriously and respect every job whether it is small or not. They arrived early in the morning and was done in about 2.5 hours. The process was as smooth as it could get.The even cleaned up the room after they were done. I highly recommend them. read more

They were awesome. They did a great job replacing our 50 year old insulation and building a deck for storage on top of the new stuff. The responsiveness was great, from start to finish, and I have high expectations. Very happy with the service, and recommend them without reservation. read more

I contacted Capital Insulation for my attic insulation issue and they came out and gave a very competitive quote the very next day. Although I didn't hire them eventually because of a prior commitment but I am extremely satisfied with their customer service, especially Molly and Karl who are very polite, knowledgeable and friendly. I highly recommend them for your future insulation needs! read more

I called for an estimate for my basement and crawl space where a pipe had cracked. I was happy. The estimator gave me good suggestions and tips if I wanted to do the work myself. It was a good experience; I'd recommend them and use them in future. read more

We couldn't be happier with capital insulation! Karl came out the same day we called to get a quote. He actually took a lot of time crawling around in our squirrel feces infested torn up half insulated attic! He answered all of our questions very thoroughly and gave us a lot of insight on what to do. It's not every day you need to fix up your attic. We got the quote about 2 months ago. Just last week we were ready to schedule and Karl and his team came out this morning first thing and got the entire job done! Attic clean up, platform building, new entry way, the works! Done by 6pm and no mess left. I highly recommend these guys. Not only are they punctual but Karl is one heck of a guy! Very laid back and professional at the same time. Hopefully the company will still be going when I need the work done again! read more

Karl is thorough and professional with his estimates of what you need and what it will cost; photographs were very helpful. I truly appreciated the two estimates he gave me; one for minimal work and one to do a thorough job. That way I had a choice. Also, he gave me the 5% senior discount without me even asking! I decided to have everything done in the attic that needed to be done and am very glad that I did. He was able to complete the work a bit faster than predicted and he and his crew are thoughtful and professional. read more

My wife and I bought our home last spring and knew the attic insulation was too low from the home inspector. Last summer we could feel a big temperature difference between upstairs and downstairs, so this spring we called around and had a few estimates. Karls estimate was actually just a bit higher than the other that we considered, but his knowledge and ideas are what won me over. He pointed things out that the other guy didn't mention as well. On install day he and his helper arrived early, worked hard throughout the day, and did a great cleanup job when complete. Our attic insulation went from ~R15 insulation value to R49. Now that it has been warming up and we have had a few stretches of hot days, I can definitely tell the difference the new attic insulation has provided. Last summer, the difference between the upstairs and downstairs was probably around 10 degrees. Now I would guesstimate the difference to be about half that. The investment is definitely worth it to do the insulation, and Karl at Capital Insulation is definitely the guy to do the work. After he finished up I was talking with my neighbor and he asked for Karls information. read more

Karl and his crew just left, having done all that he agreed to do at the agreed upon price. Everyone was polite, professional, and actually left the carpet beneath the attic cleaner than before he arrived. In addition to "tuning-up" the attic, he and his team also did what appears to be a very thorough job with an un-insulated space beneath a cantilevered kitchen. Everyone took the same care with this much smaller job as he did with larger job. What I especially liked about Capital Insulation is that they didn't try to over-sell me. They recognized that I was looking for relatively modest work done on an aging house, and responded with a reasonable quote that reflected this. I would recommend Capital Insulation without reservation. read more

Karl and his team did a fantastic job adding insulation to our attic. He was on time and did a very professional job. He even installed an area where we could store some items. I would recommend him to anyone seeking to insulate their attic. Great job Capital Insulation! read more

Karl and his team did a tremendous job removing our 55 year old insulation, making minor repairs in the attic, and then installing new insulation. I was impressed with their professionalism, attention to detail, and skill. Karl conducted a thorough inspection of our attic and identified a couple potential safety hazards which we had fixed. He is straightforward, responsive, efficient and provided clear and ongoing communication throughout the process. He takes pride in the quality work and the service they provide. Karl's team were all very respectful and polite, extremely focused and hard workers, and were very conscientious about keeping our home clean. They certainly exceeded my highest expectations which is very rare for me! I couldn't be happier with Capitol Insulation! Thanks Karl and Team! read more

My husband and I had a FABULOUS experience with Karl and his team. We purchased a home 5 months ago that came with a LOT of issues... critters, water damage etc. From the get go the team was amazing. Molly, his Office Manager, is incredibly efficient and worked with our schedule for the initial consultation. Karl showed up early and was so knowledgeable! He brought a potential fire hazard to our attention and as another Yelper mentioned was spot on with his genuine care to make our house "Right" he advised us not to insulate an area that would have probably profited him another couple of grand. Karl is a good guy. No other way to put it. He is by far one of the friendliest and most trust worthy individuals my husband and I have come across in years. His laid back attitude but matter of fact knowledge is incredibly comforting. He and and his team showed up 45 mins early for the job and while removing the unmentionables from our attic discovered a MAJOR issue with the HVAC vent that he FIXED without charging or even bringing up until he was walking out the door. Again, I cannot explain the impossibly impressive attention to detail this man has... Molly warned us that Karl is a perfectionist and Dear God the man is!!! I just wish he would expand his business to encompass more home repairs because he truly IS a gift from God! BRAVO read more

I actually had the work done this past summer and have been meaning to write this review. Karl, the owner, is a stand-up guy. He was actually the only estimator who crawled up into my attic/crawl space to fully understand the extent of the job. His estimate was very thorough... in fact, he wrote it two ways since I was unsure as to whether I wanted some of the things that he recommended. I wouldn't wish the job on anyone, as I have a very old house and the attic space is very cramped and difficult to access. Despite this, his crew did a very thorough job, all personally supervised by Karl. It was a warm day (even though they started the work as early as possible to beat the heat), and I liked the fact that he was careful to have his guys take multiple breaks. They did a fabulous job of cleaning up after this very messy job. I couldn't be more pleased. I highly recommend Capital Insulation. read more

Capital Insulation was one of three contractors I interviewed to fix my insulation problem. Karl came out and was very thorough, polite, and on time. He took the time to explain what my problems were and how they could be fixed. His estimate (which was delivered in less than 24 hours) gave me a range of options based on what I could afford. His team arrived on time and completed the work in the time expected. Services provided: removed the insulation that was in place, sealed seams exposed in attic, closed off and insulated open space for second floor stair case, fabricated and installed insulation protectors for recessed lighting canisters, insulated all bathroom ventilation fans, connected ventilation fan exhaust to existing vent piping, reinstalled previous insulation, added 10 inches of blown-in fiberglass. Results were outstanding!!! Before his work, when the temperatures dropped into the 40s outside, second floor was 8 degrees cooler than first floor and my heater seemed to be running constantly. After his work, upstairs is now warmer than first floor and the basement is even pleasant to be in now (plus the heat doesn't turn on every 15 minutes). His estimate was 50% less than the next lowest bid I received. read more
