We provide "comfort and energy solutions".
"A total disaster. An inexperienced, untrained crew created more issues than I had before they began their work. My goal was to increase comfort levels in my senior-living, one-level home built on a slab that is super cold in the winter. I hate as a senior being taken advantage of. I was very naive. I have spent thousands and now am having to throw more good money after bad to try and make my home comfortable to live in. It is so bad; I am ready to sell! And I can’t afford to after all I have spent, without taking a loss on the sale. They dense packed my walls and now I am colder; in the process, they removed the flashing above my windows which now leak. I had to hire a window installer to replace the flashing that their incompetent crew removed. They failed to put back the siding properly, so it was hanging off my house. Once again, I had to hire a handy man to refasten the siding the crew removed while dense packing. And the dense packing was useless as it didn't enter the cavities that already had batt insulation. While spray foaming triangle boxes, boots, and plenum, they sealed off all my dampers resulting in zero air flow. They reluctantly came back and had to dig out the dampers that they had foamed over. In fact, they over-foamed at junction boxes, boots, and plenum so that HVAC techs couldn't even tune my system. There is 2 feet of foam, yet hot air is rushing out of the flexible ducts that weren’t sealed properly. Yet there remain gaps on my boxes, boots, and plenum. Just today, a HVAC tech walked me around the attic, and I could feel the hot air rushing into my attic at the junctions, boxes, boots, and plenums that are all wide open; that I paid to have sealed. I almost threw up; I am heating my attic! And the tech said it looks like a dog was in my attic as the Comfenergy crews failed to put back my blown-in fiberglass insulation they removed when trying to foam, so there is no insulation at the boxes and boots. They were simply careless and failed to rake it back and even out my insulation resulting in further cold spots I didn't have. In short, I now will have to hire another company to blow in more insulation and make sure it is even, so I don't have cold/hot spots. Additionally, they left the lights on in the attic, didn't replace the attic access foam barrier, and failed to seal the major penetrations including light cans/recessed lights and supply vents I paid for. Next came the bathroom exhaust fans; they were installed improperly and didn't vent because the outside flaps remained closed, while inside a cold draft came in my bathroom because the foam sealing, I paid for wasn't done properly. So now both my bathrooms are drafty. They were cold; now they are cold AND drafty. The HVAC tech today remarked he felt badly that I have two or more space heaters in every room, including the bathrooms! I strongly recommend carefully watching the crew if you ever choose to allow them to do any work for you. I trusted them. And I regret that. I was naive. I was cold. Rather I am still cold! I trusted their salesperson. The crew that did mine were either let go or quit. In fact, one of them still calls seeking to do side work. I politely declined. I suggest you do the same and seek a competent company that you can trust, does the work you paid for properly, and doesn't damage your home."

Paul Henry's Window Installation Inc
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."

Locally owned & operated. Serving DC, MD, VA, WV. Free estimates & inspections for pest control, wildlife removal, and insulation services.
"I hired EPC for a mouse problem. I did sign a contract agreeing to you for additional treatments at $105 each. Unbeknownst to me at the signing of the contract my dishwasher is bolted to my kitchen counter and cannot be moved so the exterminator cannot seal the hole. I sent environmental Pest Control an email stating that was the reason why I wanted to discontinue my service and if they felt necessary to turn me over to collections. Instead they decided to go behind my back and deduct two treatments for total of $210 to my account. No one even had the courtesy to send me an emai. The owner has ghosted me I have turned it into my bank and it's fully expect a refund. I would never hire this group of incompetent help again."

"Beware of long term service requirement to get any help. Nearly $12K on a whole home generator, but they will not come out to help unless you are part of their long term service contract plan. Their system is set up like "Pay to Play". Continue paying the monthly/yealy price to be a part of the exclusive service club or they will make you wait a week for help. Safety of system is irrelevant, you either join their service club or you are out of luck. Spend your money elsewhere unless you are willing to continue feeding the PIG to get service."

"The crew showed up promptly and worked hard throughout the day. I was concerned about fumes from the mold killer and paint, and did get a headache, but the fumes evaporated quickly. The guys were careful to make sure that things were draped or masked so that they didn't get oversprayed with paint. My one regret was that I didn't ask to pay extra to have the guys put everything back afterwards...what the two of them accomplished in a couple of hours is taking me days and days to put away."
