About us

Northern Virginia Insulators is a U.S. Armed Forces veteran owned and operated insulation company focused on providing excellent customer service, value and professional workmanship. Northern Virginia Insulators was established on the basis of integrity and hopes of earning their customers trust in the process of servicing them. We will give you the fairest price in the industry and if by chance we are undersold, we will make every effort possible to meet any competitors price. We don't practice up-selling to our customers on services they don't need. We will investigate your home for possible solutions and advise you on the most affordable and economically sound ways for improving your living conditions. We specialize in dry insulation applications to include blown-in and rolled/batt solutions. Armed with an array of insulation products, we will discuss the positives and negatives of each option until we find the product that suits you. We are a small company with no vision to become the largest insulation house in the area. We want to bring you a personal and up close approach to servicing your needs. Retaining that personal appeal when communicating with our customers is important to us. We don't want our customers feeling lost in the process of servicing them. Estimates are performed by the Owner and all work is performed by or supervised by the Owner as well. Customers will have direct contact with the owner of the company from start to finish of all projects. In addition, Northern Virginia Insulators does not use subcontractors. We won't trust our work in the hands of those with no vested interest in the results you see and ultimately live with. Improving your living conditions and giving you peace of mind that the work was done with care and accuracy is our primary goal. Appointments are available 7 days a week.

Northern Virginia Insulators removed and replaced the blown-in insulation in part of my attic after my living room ceiling had to be replaced. Brad was prompt, professional, and accompanied the crew on the job, which required two visits. Their price was very reasonable and Brad was easy to work with. I would highly recommend this company and will use them again!

They were a great fit for our smaller size job. Brad and team were very responsive, brought the right expertise, and did a great job minimizing and cleaning the mess. Best of all, their pricing was very reasonable for the work that needed to get done.

From the initial estimate with Brad, to the work performed on a Saturday, everything was done carefully and with attention to the smallest details. They are a local firm with exceptional service and I would highly recommend for services large and small.

I heard about this company through my neighborhood listserv. They were as good or even better than I was told. Came by for an estimate and explained the options, including some challenges they might have in a confined space. Performed the work over a weekend at the price quoted and within the timeframe they said they would. Professional and punctual and cleaned up afterwards. Excellent work! Everything I would have asked for, but somewhat rare today. I gave them Five Stars and they deserved every one of them. Kudos.

Attic Insulators of Northern Virginia arrived promptly. The work was done as scheduled and as promised. They were very professional and cleaned up after the job was completed. We have already recommended this business to our friends.

Northern VA Insulators was hired to insulate our attic (a two story single family home). They showed up on time, were very professional and protected the carpeting were they had to walk and work. Brad, the owner came out at the beginning and end of the job to make sure we were satisfied. We would recommend this company to anyone that is in need of insulation services. The crew was great!

Brad did great work at a very reasonable price. He was responsive and punctual. We had our 20 year insulation replaced with a much better product and have already seen a significant difference in our utility bills.

Brad and his team did a great job adding new fiber glass insulation on the the top of the existing fiber glass insulation in our attic, was expensive but have not seen yet any significant increase in R value/ comfort level & drop in cooling/ heating bills

Northern Va. Insulators helped us out once again. They are very professional and efficient. We contacted them to insulate our attic and crawl space of a new home we were renovating and they performed the work in a timely matter. I will always use their service when needed. I highly recommend this company.

Excellent! Great price even better service, outstanding results. Still a little early but we have seen $25-$40 per month reduction in our electrical bill July-Sep. A?C runs about 50% less now days and maintains temp very well. The crew was on time, polite, lets you look over their shoulder, very careful and setting up and teardown of equipment. Brad Simmon's is a stand up guy and while he answered my many questions at no time tried to up sell us.

The old insulation above my crawlspace which was installed by my pest control company had fallen down after only 6 years. I decided to get a professional insulation company to replace it figuring they would do a better job because insulation was their specialty. I sure was right! I called Brad at Northern Virginia Insulators for an estimate on August 9th. He returned my call in an hour and came over and gave me an estimate that same day-$2635. They scheduled me for August 25 and showed up on time. They used foam sealant to seal air penetrations and used bat rolled fiberglass insulation. They installed wire mesh to hold the insulation in place. They were done in 3 hours. They did an outstanding job and I would highly recommend them. They gave me what I needed and did not try to sell me what I did not need.

The whole process from scheduling an estimate to having the work done was extremely smooth. Brad and his crew were prompt and capable of clearly explaining what work had to be done and why. They were well-prepared for the job and cleaned up thoroughly when they were finished. I will happily recommend the company to anyone else and will be calling them back for any further work I need done.

First off, they performed an assessment of the attic insulation and gave us a detailed brief on what they saw. They told us what we "NEEDED" instead of what they wanted to sell us. Very honest and great company to work with. The installation went much better than expected. No mess. They were on time, laid out all the protective tarps and briefed us on what they were going to do. The job went smoothly. At the completion, we took a look in the attic and the insulation was very even throughout the attic. I'm sure it was difficult with all the extra trusses up there making things very cramped. I would highly recommend them for any insulation work I needed done.

Very pleased with the comprehensive work done in my attic, including removal of old fiber glass insulation, foam seal of attic space, baffles and new all-borate cellulose insulation. The owner was there at the job site reporting to us. The crew was nice. They protected our carpet and cleaned at the end.

Answered all of our questions during the quote and follow-up ones later. Easy to schedule for a quote and for work to be done. They arrived on time and were polite. Added extra insulation also because they had some left over. Cleaned up area and left the house clean. I would recommend and hire them again if needed.

Couldn’t have asked for more. Arrived on time for estimate (as the saying goes 5 minutes early is late, Brad showed up 10 early to be early!), provides detailed estimates with options and advice to what makes the most sense for my situation. On day of install, again on time, all employees following COVID rules. His team took time to show me the different steps, clean out, sealing, and after blowing in insulation. Cleaned up and left house and yard clean. Will recommend to friends and neighbors. Thanks
