Customer Satisfaction is our number one priority and we promise that we can make a real impact in your home in a way that keeps you happy every step of the way.

"Atlas home energy solutions did an outstanding job from start to finish. They were professional, knowledgeable, courteous and easy to work with. All the crew members Ben Mott (was very knowledgeable, did the home energy audit, followed up with competitive quotes, which was adjusted to accommodate my request, offered BGE rebates upfront, patient and friendly to attend my calls and answer all the questions), Zam (Crew leader who did the exhaust fan installation), Tun (Crew leader who did an outstanding job to insulate the attic and basement), David (Crew leader who did duct cleaning and Aeroseal) were phenomenal and did an outstanding job. The end result is a day and night difference before and after the work and my BGE bill last month went down by more than $100 which is a huge cost saver. The HVAC does not run that much these days and the temperature is pretty even across the 30-year townhouse. I highly recommend Atlas home energy solutions for home energy audit and improvements."

"The company deserves 1000 stars l. Chris came and gave a well thorough inspection and estimate of my actic. Had my concerns and expectations, I had several other companies come and give quotes for double the price. Especially ORKIN. Orkin tried to use care tactics to sign contract without any explanation. Chris gave the quote and the crew arrived a week later as scheduled. Chris has a great work crew who were professional , caring, and did high quality work. Every step of the way, I was communicated and was filled in. I was shown before , during and after photos. And end results were UNBELIEVABLE Chris is fair and honest, he gives reasonable prices and will not take advantage of his customers."

"We are having our HVAC replaced and our salesperson recommended DUCTZ. DUCTZ came out on-time today to clean our air vents. The communication prior to the visit was very clear and it was easy to understand the upcoming process. They were very considerate, we toured our home and they went right to work bringing in the needed equipment and moving necessary furniture to access the vent covers. They were diligent and stayed focused on the task. Before I knew it, they were reattaching the cleaned vent covers and removing the equipment. Within a few hours, we had before/after pictures and have a great sense of comfort knowing all the gunk is gone! I highly recommend DUCTZ!"

Paul Henry’s Window Installation installs superior-quality energy-efficient:Windows, Doors, Siding, Decks, Gutters, Roofs & Attic Insulation. Our products and services will beautify your home and dramatically reduce your home heating and cooling costs. Paul Henry and his installation crew have more than 30 years' experience providing home remodeling services to Northern Virginia homeowners.

"From the estimate to the installation Paul and his crew were awesome. My wife and I were very nervous about the preparation we had to perform, curtains down, furniture moved etc. We also expected some drywall and paint damage. We're both older so this was a huge albatross and as such we kept putting it off. We finally decided to bite the bullet and get it done so I asked Brian Henry if he could come out to review my furniture moving plan to assure we gave them the required space. He came out and was extremely professional, helpful and put us completely at ease. Several weeks later Brad and James were out to install the windows and three days later were done with absolutely zero damage to drywall or paint. And in fact since the bay windows were primed they didn't even need painting although we'll do it anyway. To top it off, they even protected our landscape in front of our widows and all plants survived. Brad and James were polite and meticulous with the installation. They covered everything up inside our house and put down extra thick tarps. They were punctual in starting each day and finishing. They patiently answered all our questions addressing our concerns. And they were complete in 3 days as we were told. Once they were gone, you couldn’t tell they’d even been here. In fact, I looked around and commented to my wife that we’d never spent so much money on something we couldn’t even see. To be clear the windows looked almost identical to those that were removed except for these being brand new. I do expect our electric bill will be reduced and I suspect they will be a good selling point when we move. Finally, the cost was very fair, I had reached out to two other firms and both were substantially higher. The original windows had also been installed by Paul Henry so I was very comfortable even though his costs was lower. Bottom line, we highly recommend Paul Henry Windows."

Insulation questions, answered by experts

If you have bubble wrap lying around the house and you don’t care about the odd look, taping bubble wrap over a window is a very affordable way to insulate it. Another inexpensive option for insulating windows is to add new caulk around the glass. This step quickly cuts down on air drafts for older windows, and a tube of caulk only costs a few dollars. Adding plastic shrink film around the glass is another cost-effective option. You can purchase a kit of plastic film for a few dollars per window.

Heat lost through uninsulated basement walls can account for up to 30% of the total energy lost through heat transfer to the outdoors. While homes in mild climates won't gain as much benefit from having an insulated basement as those in cold climates, the effects are still noticeable on your energy bill.

DIY installation is feasible with the right protective gear and knowledge, but professional installation ensures full coverage and maximum efficiency.

Depending on the size, insulation condition, and removal method, it can take anywhere from four hours up to twenty hours. Therefore, be prepared to split the projects into phases, or leave it to a professional. Insulation is an intermediate project with various risk factors and can be challenging to someone unfamiliar with the process.
