Marvin was the team lead for my project (Reston, VA). He was professional, answered all questions, explained the work as the team progressed throughout the day. Excellent team work -- I noticed that Marvin "managed" his team and the work in a professional manner. I also noticed that some of the team members asked Marvin how to proceed and he responded in a courteous, professional manner. His team did a wonderful job, cleaned up. I would definitely recommend Comfenergy based on my experience with Marvin as the team lead.

We hired USA Insulation to blow insulation in our attic, which had very little exisiting insulation. They were prompt, courteous and friendly. The insulation service was quick and the installers did a great job of cleaning up. The insulation has made a huge difference in our indoor temperatures. We were very happy with the service and the results!

I wish there was an option for an "A+", as I could not have been more happy about the work provided by Absolute Insulation. Absolute Insulation was very professional and knowledgeable about insulation. The final costs of the job came in slightly less than the estimate. The insulation was replaced over 2 days. The first day, they cleaned out the old formaldehyde-filled insulation with a giant vacuum cleaner. They ran the vacuum cleaner tube through a 2nd floor window, and there was no dust and dirt in our house after they were done. I had received estimates from other insulation companies that did not clean up the attic first, but just put new insulation on top of the old, dirty and ineffective insulation. So I was very happy that Absolute Insulation cleaned the attic. The second day, they put in the new insulation. We had opted for blow-in fiber glass (the materials used were environmentally certified). The insulation work took about 4 hours. They put an even cover in. There was no dust or dirt in the house when they were done. Moreover, they covered the attic opening, and back of the hatch, as well as the space around our all-house fan with insulation mats. Two weeks later, there has been no settling (e.g. shrinkage), and the insulation is working wonders in preventing the upstairs from getting hot in the summer. Due to the savings on cooling costs in the summer and heating costs in the winter, we estimated that the insulation work will pay for itself within 2 years. I had received estimates from two other insulation companies. Absolute Insulation was by far the superior. It was the cheapest, they cleaned out the old insulation, and they were not carrying dirty materials and bags through the house. They were also the only company that did not overestimate the square-footage of our house.

Quality Insulation

We used Quality Insulation twice and there was only one item that could have gone better. Quality Insulation insulated our attic in our renovated rowhouse. The developer forgot to insulate the attic (oops!) Quality insulation pumped insulation up there. Their guys were great about making sure the insulation was spread throughout a very shallow attic. We had Quality insulation (QI) back to reinsulate the floor under our kitchen. The area used to be a sleeping porch and the insulation installed there did not seem to be doing much. QI reinstalled insulation there the right way and the floor became much less drafty. The one complaint I have is that there is an area under the floor of the bathroom that is still overly affected by the outside temperatures. That is the one area that was sealed up again before I got outside. I would have liked to see what was going on there related to the plumbing and the amount of insulation able to be packed in there. Between the floor being drafty there and the toilet conducting cold from the outside, that bathroom gets cold quickly. Besides that mystery, I was happy with Quality Insulation.

Dan and the crew of Quality Insulation were great. Dan was very kind and explained the work that was needed and guaranteed that my husband and I would not have to have to worry about insulation again. He is honest which is important to me and gave a good affordable price for the work. The other companies that I called before I called Quality Insulation wanted to charge twice as much for my insulation. The workers respected my home and the process was very clean. If you need insulation I would highly recommend Quality Insulation.

Fantastic experience with Kelvin. Very quick response for an initial estimate. Came out to check it out within a few hours. Also helped me out immensely by doing the job on the weekend which he normally doesn’t do! Definitely highly recommended!

We used Efficient Energy Solutions to spray foam our old farmhouse attic/roof as well as our detached garage. From the initial consultation all the way through the installation and follow up we were SO happy and impressed with the above-and-beyond service. We will be recommending to everyone!

From my first inquiry all the way to the completion of my project and beyond, EES has been an absolute pleasure. I was kept up to date on each phase of the process from proposal on and invited to ask questions, (which I did! LOL. This stuff is awesome!). Not long after my attic was done, Chrissy called just to see if I was happy. Great customer service! I highly recommend this company. Not only for the energy savings, (which is significant), but for the people. They say what they are going to do and then they do it. Well. My sister and my dads houses are next!

The two man crew was on time, I really appreciated that they work weekends which is more convenient for us. They installed blown insulation in two attics, including some batt insulation on the walls. The crew spent several hours installing the insulation and cleaned everything before leaving.

Wow!! Terrific!! I'm writing this letter to thank USA Insulation for the wonderful job that your energy consultant and installers did by insulating my home. I'm so happy with the results! My home was not well insulated, and I immediately noticed it was warmer and more comfortable after being installed. Everyone at USA Insulation was so courteous and knowledgeable through the process. I was so impressed that everything was completed in one day, and the crew left no mess behind. Thanks so much!!"

USA Insulation

Everyone was very professional and accommodating. "Interviewed" multiple insulation companies before choosing USA Insulation to address our almost completely uninsulated attic. The pricing was competitive. We really appreciated their approach to our service needs and various requests/questions. The work was done very well, efficiently and exactly as promised. We are pleased with the results. We recommend USA Insulation to others and would certainly consider them again ourselves for our future insulating needs and/or projects.

Max Insulation

Max Insulation quoted a price to blow in energy-saving cellulose R40 roof insulation and blow in foam sound-muffling insulation along a basement rowhouse wall in Capitol Hill. Both items were done on schedule, on budget, and on scope. There was a bit of cleanup needed after the roof insulation was done, but Mike had it taken care of. He has a good drywall guy who opens trenches in the roof, then closes them back up in a professional way right after installation. I am calling to inquire about another house insulation project today.

Description of work: a full tear-down of existing insulation; identification and insulation of draft sources that had caused water pipes to freeze; insulation of surrounding walls and gaps; installed heat-reflective finishing over insulation; placed wrap insulation on water pipes; rebuilt drywall. The work, which involved a difficult reinsulation job, was performed very timely and thoroughly. Dan and his people were very responsive and attentive, and the final result appears to fit the bill exactly. Price was very fair.

Hired USA Insulation to insulate the attic of my 1958 rancher. Job went off without a hitch. Had 20 inches of blown insulation put in the attic along with an extra layer over all the duct work in the attic. Crew arrived on time, was courteous and cleaned up before they left. Working with USA Insulation was a great experience and I would definitely recommend them.

Dan and his team did a fantastic job. Our new home did not have any insulation in the attic. Quality insulation came out and within a few hours air sealed and insulated our attic. They provided about 1000 lbs of blown in insulation. They were very professional and cleaned up after themselves. I came home from work and could not tell that we had workers in our house. Dan also took pictures and sent them to me so that I could see each stage of the process. Would recommend them to anyone interested in insulation.

Quality Insulation

Quality Insulation did a fantastic job. They arrived on time, did a thorough and professional job, and cleaned up after themselves. The blown-in insulation used was applied in a very even layer throughout the attic and the attic entryway (folding stairs/trapdoor style) had a wall of batt insulation constructed around it to hold back the blown-in insulation. High-R reflective plastic insulation was used to form a cover over the entryway to prevent energy loss in that area, yet allow periodic access. Dan's team also sealed the many draft points in our basement walls. I'm very pleased with the results.

Why hire an insulation contractor?

While insulation may be done as a DIY project, hiring a professional is always a better choice. They have the experience and expertise to inspect your home and analyze areas where insulation is most needed.

Insulation contractors will also check the home for any existing air leaks so they can seal them prior to adding an insulation barrier. In addition, they offer critical advice regarding the best insulation material to use for your home.

How much will insulation installers near me charge?

Most homeowners spend between $3,500 to $4,500 to insulate their entire home.

This cost is often lower if only specific areas need insulation (such as the roof or the basement). Some common areas of the home requiring insulation include:

  • The attic ($1,700-$2,000 for a 1,200 square foot attic)
  • Exterior walls ($3,000-$7,000)
  • Cathedral-type ceilings ($360- $720)
  • Basement ($1,200-$1,800)

What factors should I consider? What about labor?

Cost will depend on the amount of labor required during installation. Labor costs often lie between $0.95 to $2 per square foot. In addition, the materials required for insulation may also add to your final cost. There are several methods through which insulation can be done.

  • Spray foam: this involves insulation foam being applied directly to surfaces of interest using a spray gun.
  • Foam board: consists of caulking and furring stripes being applied on walls using an adhesive.
  • Loose fill insulation: this method uses a machine that applies fiberglass, cellulose, and mineral insulating materials on surfaces of interest.
  • Blankets: involves using batt and rolls to place and staple the insulating material on specific surfaces.

Insulation contractors will play an important role in advising on which type of insulation to use. Make sure you work with a licensed and experienced professional who provides transparent pricing.
