After 40 years, our insulation was falling off. We also had (they discovered) squirrel damage. C.I. had a team of extremely hard-working folks who removed all the old stuff, repaired the squirrel damage, and then sprayed foam throughout our attic. The work was noisy and their workday was long. But worth it. The price was not inexpensive, but we believe for the number of workers, and the extent of the work, the price was fair. It's not something I want to be good at. read more

Do NOT use this guy! They aren't at all trustful We asked for a wrongfully check to be returned after they said it was incorrectly written only to find out that they ended up deposited. Not sure I can trust the work they perfumed was accurate after they lieded and never returned our check. read more

Capital Insulation recently insulated my attic and did an amazing job. I got 4 estimates before I chose them. They were not the cheapest but their quote was detailed and explained every step they took to install the insulation. They arrived at my house right on time and worked for 11 hours straight. They were meticulous removing all of the old insulation, sealing gaps, and blowing in new insulation. The difference in the comfort of my house was immediate. No more drafts. A few days after they finished, it snowed. Normally the snow would melt off my roof quickly due to all of the heat escaping through my attic. That is no longer happening. I'm so glad I chose this company. They are worth every penny. I highly recommend them! read more

When my Dominion Home Energy Report showed that I "used 101% more electricity than average homes," I knew it was time to do something! I read reviews and then reached out to several companies for an estimate to replace my attic insulation. Capital Insulation provided an itemized quote that was the best value. I was happy every step of the process from working with Karl on the estimate to scheduling the installation with Lisa and communication with the crew while they did the work. The installation was completed quickly, they cleaned up when done, and payment via bank transfer was simple through QuickBooks. I won't hesitate to recommend Capital Insulation to friends and family. read more

We used them to redo the insulation in our attic. The team that came out was very professional, incredibly friendly, and kept me updated throughout the process, and while it was expensive, it wasn't out of line with other companies in the area. My only complaint was related to the guy who gave us the estimate (Kyle I think?). He spent about 5 minutes in the attic and told us that it would be a really easy job, would be done in about 3-4 hours. Well, it turns out he missed things so we ended up with additional charges, and the process took closer to 9 hours, so I do feel somewhat misled by the estimate. Also they didn't replace the window screen they'd removed...which was not a huge deal, but kind of a pain to get it back in place. Overall still happy with the service. read more

We were notified that are check was written incorrectly and couldn't be cashed. I asked for it to be returned, but was told it wasn't valid only to find out thorough our bank they actually cashed it. We wrote them a separate check that we had to cancel (that BoA charged us a fee). I emailed them/texted and never heard from them for 2 days. I plan on reporting them to the BBB. I wouldn't recommend them to anyone. read more

Capital Insulation just finished a two-day project at my home, removing old, poor quality attic insulation and replaced it with 21 inches of blown fiber glass insulation. They sealed joints, insulated and sealed around sky lights, recessed lights, put new covers over recessed ceiling lights, etc. Jon, team lead, is awesome, a true professional, and task focused to deliver superior results. The crew worked together well with a positive work attitude which I admired. You can see they enjoy their work and take pride in what they do. Since most of us home owners don't get up into our attics much, if at all, it is important to find a company you know will do the work you pay for. This is a high-quality company with integrity that will do outstanding work for you and you will no longer need to worry about what is going on in your attic. Karl, the company owner, was also in the attic doing work at my home and pointing out to me things he found and offered solutions for fixing problems. With 21 years' experience doing insulation work, Karl is someone who knows his trade. In all, I am extremely satisfied with the project's outcome; I got what I paid for. read more

Brand new insulation installed this week, crew showed up on time, very pleasant to work with, clean up after they were done, here's hoping that my utility bills go down a bit! read more

We had a great experience with the team at Capital Insulation! They responded to my request for service immediately, and set up a time to come to the house for an estimate the next day. Not only was he very thorough and honest about what we needed, he identified some fire hazard concerns that existed and made suggestions for maximizing the use of our attic space. Lisa was wonderful to work with via email, very thorough and timely in her communication for scheduling and estimates. The crew that came out to perform the work was on time, and thorough, all around great guys who worked extremely hard to complete the entire job in one day. They were clear about costs, and the final product looks fabulous! Very happy we had them build a storage platform, as well as remove and replace all of the insulation. I would highly recommend this team, real professionals! read more

Quick response, but it shocks me that a company named Capital Insulation responded to me that they aren't licensed to work in DC. Completely disappointing, especially since the map shows at least part of DC within their range of service. (Edit: I've added a star due to the company's quick reply, but this service area really seems like a major thing that should be mentioned in the company's description. I do appreciate the rapid communication, but I cannot speak to their services.) read more

Capital insulation did a great job! Karl came out because the 3rd level of my townhouse would always get warm during the summer months. He was the only contractor who actually got into the attic and looked around to properly inspect and make a recommendation. Similar to other reviews Karl gave me 2 separate quotes for R38 or R60. I recommend the R60 for everyone because it has dramatically decreased the temperature. Karl and his team came on time and once the job was completed they cleaned up and you would never have know they were there. His pricing also beat most of his competition. Will highly recommend Capital Insulation and Karl to friends and family members! read more

Super friendly, helpful, did a high quality job, discouraged me from extra add-ons that they didn't think I needed, but did them well when I insisted. Easy to schedule with. Overall just excellent. Also, cheaper than the other quotes I received read more

excellent responsiveness and service. the company installed our insulation professionally and cleanly... will recommend to our friends! read more

Capital Insulation - added insulation - Insulation Installation Near Me

Capital Insulation did closed cell spray foam rim joist insulation for us. Great value and such a pleasant team that came and did the job. Would absolutely recommend them and would hire them again myself if ever the need arises. read more

Excellent experience. Price was reasonable and service was great. I would recommend this company without hesitation.

Capital Insulation did a great job removing my original insulation, sealing everything in the attic, and putting in new insulation up to code. They responded quickly to my original inquiry and came out to give me a quote. Karl actually gave me two quotes to choose from (removing old insulation or leaving it) as well as choosing R38 or R60. They were able to schedule the work within a week. The work itself took 7 hours and Karl vacuumed afterwards. He also took some pictures in my attic of a couple problems he found and talked me through whether to fix it or not. They did great service and great work. My AC is running less often now and my upstairs is comfortable to sleep in. read more

Karl was the only estimator that really knew what he was talking about, and provided a comprehensive and fair estimate. He and his crew left my attic in much better shape than when they found it. My house needed this for over a decade; learn from me. I highly recommend them on quality and value. read more

Karl came by to look at our attic. The problem wasn't really the insulation, it's the ventilation. He provided some good suggestions, but most importantly, he didn't try to sell me any unneeded insulation! read more

The owner and four employees showed up at 7am and were done by 9:30am. Super professional, knowledgeable, cleaned up and friendly. Thank you - highly recommend! read more

Capital Insulation - Attic view - Insulation Installation Near Me

Karl provided me with an estimate which had several options. He told be his opinion regarding the options, and I went with his suggestions. On the day of installation (we had additional insulation put into all three attics), a team came out first thing in the morning. Kyle, his son, explained what they were going to do and then placed tarps on the floor in all areas that they were going to work. Kyle kept me updated throughout the project and made suggestions as he went along. When the job was completed, the crew cleaned the areas and vacuumed. They did an amazing job and I appreciated the photos Kyle took in the attic, showing exactly what they did. More importantly, when I woke up the next morning, the heat in the house was warmer than it's ever been. I had to lower the temperature on my thermostat. Great work, reasonably priced and effective results. I highly recommend this company. read more

Karl came out and checked out my attic as I was having issues keeping my living room cool during the summer (large cathedral ceilings with skylights). Karl looked through the entire attic and took the time to crawl through a very small opening into another portion of the attic (the only access point) to specifically look into the living room area to make sure they could provide good insulation coverage. Karl said they could definitely do it and even suggested some other areas that may be causing the excess heat buildup in my attic (roof vent opening size which he was correct and has since been fixed by the original roofers). Karl did some carpentry work to ensure there was a higher level of insulation in the attic and built a custom box for an attic fan that would ensure no squirrels or raccoons could enter my attic from the roof. Overall it was a great experience, Karl and his team were very prompt and professional and left the house in better condition then when they first visited. The work done was excellent and the purpose of everything was explained ( I ask a-lot of questions) very thoroughly and professionally. I would definitely recommend this company to friends and family; give Karl a call and I'm sure you will feel the same way just from the estimate. read more

Karl did additional work which deserves mention. He and his helpers, particularly Ted, filled in some gaps left by a renovation contractor. The job was small and very difficult, but Karl's work produces major and immediate benefits. Ted crawled through an impossibly small access hole to apply foam sealant to small gaps and then blew fiberglass into a small but poorly insulated space. These guys are sincere and businesslike and I recommend them without hesitation. read more

After getting two other estimates (#2 didn't even look in the attic, then pressured me to sign immediately on an over-priced contract or pay more than twice the cost I ended up paying), I was ecstatic to be rescued by Karl of Capital Insulation, Springfield. He did a thorough inspection, offered a reasonable price, showed up when promised, and was a Zen master who knew what the hell he was doing. His crew was efficient and capable. The house was cleaner after they left since they vacuumed all over, even under where their many tarps had been. They found a fire hazard and repaired it for free. Lisa, the scheduler, was super-efficient in moving the inspection and job dates earlier as dates opened up, and everyone was so friendly and helpful. This is as close to Nirvana as one can get in Fairfax County. I'm sorry I don't have more attics they can work on. read more

Excellent service from start to finish. Karl came out to do an estimate about a year ago for re-insulating our attic. There was only 4-6" of original insulation left in the attic. We went through a full winter and summer before getting it done. Karl and his team showed up on time and ready to work. Half a day later we had a fully insulated attic. He even removed the old house fan that was leaking air into the attic and put new drywall over it. I could have gotten the project done cheaper by a few hundred dollars but none of the contractors I had come out were nearly as professional, polite, and knowledgeable as Karl. I highly recommend him and his team. read more

Just finished having our attic reinsulated today and we can already tell a big difference in the cooling of our upstairs. Our insulation was original to the home (40yrs) and we had about a 15-20 degree difference in temps between the upstairs and downstairs. Karl came to our home and provided an estimate within a couple of days of the request. We had additional quotes and Capital was priced at a reasonable rate. Additionally, they did a very nice job of detailing out what type of work they would do and communicated effectively. The day of the work they showed up a few minutes early ready to go. Everything was done neat and tidy and very efficiently. After about 4hrs of work on a 900 sq/ft attic, they were done and on their way. I also appreciated that all of the workers were U.S. citizens. I would highly recommend them for future work. read more

Karl gave me his honest opinion about a project. Fair price. A lil unresponsive at first but was able to sort that out. Definitely will call him again in the future if I need to. read more

Capital Insulation did a fantastic job on my attic. Karl and his team were great. They couldn't have been more professional or squared away. I'm warm and cozy in my condo for the first time in years. My old roll insulation was a mess. They cleaned up the whole place and blew in fresh fiberglass, not cellulose, which is very dusty. It looks like fresh snow-not dusty at all. They tented some exposed water pipes so that they wouldn't freeze and covered over some recessed lighting that hadn't been properly installed. They built up the plywood platform to fit the higher level of insulation, but left me plenty of storage space. All around great job! read more

I found Capital Insulation doing an online search and checked their BBB rating which was very good. Karl came out to the house and did a free estimate. He was very nice and clearly knows his stuff. He was patient, listened to our concerns, and patiently answered our questions. As a new homeowner we have multiple projects in the works and he also provided us with additional names of vendors that might be helpful to us. He promptly delivered the estimate via email and then honored it almost 90 days later when we were able to fund the project. On installation day Karl called ahead and arrived early. He and his team were professional and tidy which is a trick when you're blowing in insulation. They were finished in about 2 hours after installing baffles and insulating both level of our split level. In one of my initial conversation with Karl I joked about problems with new homes and referenced the HGTV show "Holmes on Homes" - a show I'm a fan of. He shared that his goal with every job is that if Mike Holes ever showed up at a home that he has insulated that it would meet his approval. read more

Highly recommend!!! We were thrilled to find them - Dan came and was honest about what would be worth doing and what we could expect. He took time to go over everything. Easy to schedule - everything was done for our convenience!! They arrived when they said they would - worked hard!!! Cleaned up and did thorough and excellent work!!! Jacky M. read more

I had an appointment scheduled for tomorrow to get an estimate. I received an email (not a call) stating that Karl would not be able to meet with me as he has decided to remove Loudoun County from their area of service. One would think that Karl would keep my appointment and not accept any FUTURE Loudoun customers. A courtesy call would have been appreciated in lieu of an email. I suppose it is a blessing in disguise as I would not want to engage with a company who conducts business in an unprofessional manner such as this. read more

Great company and customer service. Definitely worth using these guys. They know what your house needs, in order to keep the house cool in the summer and hot in the winter. read more

Very happy with Capital Insulation. Hired them to install some flooring in my attic and move the old insulation. Karl and his crew did a great job. They were easy to schedule, showed up on time, and left us with a usable attic storage space. Karl was thoughtful about costs when preparing an estimate, and was very reasonably priced. I would definitely recommend to friends and family in the future. read more

My wife and I had a great experience with Karl and his team. During the fall season of 2015 Karl came out to assess our unfinished basement. It's a really unique space and rough around the edges. It is not insulated. After a 10-15 minute walk-through that was very informational, Karl ultimately advised us not to insulate for a variety of reasons. He mentioned that a vapor barrier in our very tight and all dirt crawl space might be worthwhile, but not an immediate need. He also gave us some good tips to manage the space which we implemented. He was basically giving us his secret sauce for free. Fast forward to March 2016 when we decided to finish our crawl space with a vapor barrier and some insulation. Karl came back and immediately recognized the space and recalled our consultation from the fall. We looked at the crawl space, and he turned a quote around to us within a matter of hours. While in the house together I asked for a ballpark estimate which he would not give. I appreciated that. When he and his team showed up to perform the work (just a week or so later) they went above and beyond. They essentially had to regrade the dirt in the crawl space using nothing but a flimsy rake and some boards I had kicking around my basement with just a few feet of clearance above them. Their work was absolutely top notch, and despite the unanticipated effort of regrading the crawl space they came in on budget. Karl and his team are very professional and they do first rate work. Would recommend any time. read more

Capital Insulation is great! It's clear that Karl knows his stuff, and he's not gonna try to sell you anything you don't need. I like his selling style--consultative, but not pushy. He gave me two different options, with pricing for each. He was quick and responsive when I had questions about the options. When it was time for Karl and his team to do the job, they showed up right on time. They laid tarps to protect our floors, and worked hard to get the job done quickly and with minimal interruption to our lives. Plus, they cleaned up so well that our house was literally cleaner when they left than it was when they arrived. Who could ask for more? I'd hire them again in a minute! read more

Karl and his guys were very professional. They were on time, finished when he said they would, and beat the big box stores prices.

Karl and his team were absolutely top notch and delivered top quality work. Karl's attention to detail during his estimate was far beyond what any competing quote I got. Because of that detail, the level of work Karl's team did relative to air sealing, fixing the access panels, protecting the HVAC unit in my attic, and radiant barrier work was far away the best quality work for my money. His quote was very competitive and I have noticed an immediate improvement. The only quote I received that was cheaper was some small company whom I am sure was just going to spray a bunch of insulation and not do the important work I listed above that Karl's team did. I did a lot of research, and I absolutely recommend Capital Insulation - Both on quality and cost. read more

Karl and his team were great. They were cordial, quick, and very knowledgeable about the process. We are happy with the work from start to finish! read more

One of the best home improvement experiences I have ever had thanks to Karl from Capital Insulation. I had the original insulation in my attic since I bought my home new in 1988. I was way overdue to add insulation for all season comfort. I did my internet research and requested four price quotes. The most thorough, most informative, most courteous, most professional of all four companies was Karl from Capital insulation. I hired him two days later. He performed the work two days after I accepted his quote. Just like he predicted, I felt the difference almost immediately. He and his crew did a fantastic job installing and cleaning up. I have no complaints, just satisfaction. I highly recommend Karl if you're looking for an insulation contractor. read more

These guys did an amazing job insulating our attic and went above and beyond to make sure it was done right. We felt a huge difference the day after in the temperature of our home! Thank you again! read more

The second floor in my house was uncomfortably warmer than the downstairs each summer. Since I recently replaced my windows and HVAC unit, I suspected poor attic insulation was to blame. I called Capital Insulation and Karl Strandberg came to my house for a free estimate. He thoroughly inspected my attic and provided a detailed estimate with optional services. He wasn't trying to sell these options, but listed them based on his findings in my attic (broken baffles/eave stops, missing insulation on the access cover, even bathroom exhaust fans ducts that weren't properly installed). The estimate was very reasonable and I quickly scheduled an appointment to have additional insulation blown into my attic. Karl arrived on time and did a fantastic job - including some last-minute things I asked him to do. He asked me to inspect his work and commented on a few things for me to notice. He and his assistant completely cleaned up after the job. I highly recommend Capital Insulation for their prices and professionalism. read more
