They installed a waterproof barrier, French drain and sump pump and cleverly found a place to install the discharge pipe without having to rip up my porch boards.

Would highly recommend!

I had a small water problem inside my basement so called Summit for waterproofing. Met Mathew from…read moreSummit where I explained what I wanted and also found out they do work in crawl spaces putting down plastic, etc. Mathew worked up a price and I signed the contract. I asked him for a copy of the contract and he said he would send one. This is on 9/10/26. I asked him four more times until October 25 when he finally send me a scope of work (no original contract). The scope of work only include the crawl space work and no waterproofing. I phoned him about this and he said he never talked about doing waterproofing (my wife came down to the basement and heard him talking about waterproofing). He gave me some crap and I told him the contract was over and I would see him in court. I thought about. this and on Monday oct 27 I spoke with one of the bosses and told him I wanted him to do the work, minus Mathew. The work was scheduled for Thursday. Material was delivered that Monday and on Thursday 2 men came and did one of the best jobs I've ever seen putting down plastic and fixing insulation. They worked all day and left at 6 pm. I have an appointment with their waterproofing man on Wednesday. It's really too bad they had such a person to begin with.

The bees were coming in through a hole in the drywall. There were hundreds of bees throughout the room. My first thought was holy s&$! Alpha pest management was recommended by one of my neighbors. Justin called me back on the day when I put in a service request via their website. While I had to wait a bit that day to get a response (this is not a big firm with lots of sales agents and so forth), I spoke with Justin (an exterminator) himself. I didn't have to waste my time speaking to some sales agent. Just asked me to send some pictures of the bees. He immediately told me they were not carpenter bees, which do not sting, but hornets which do! He came the next day to take a look around and recommended taping up the hole in the drywall. This solved the immediate problem of hundreds of bees getting into the attic. Despite Monday being a holiday, he said he was available. He came with his associate, Phillip, who does the drywall repair. Overall, a very professional and positive experience. I am very happy that these @&$!ing hornets are dead.

Five months after the job was done, the soffit patch started deteriorating and fell apart. I contacted Justin to let him know and asked him whether I could count on him to redo the work. I received no response. This company will charge you a high price for anything that is not pest management, and they will have someone else do the work with a very poor quality of materials and craftmanship. Awful customer service and even worse accountability of their work. By the way, Justin's response below is absolutely false. My advice is that you look elsewhere for real professionals that are accountable for their work.

We ended up having to fix the walls and redo the shelving ourselves. They installed the fireplace with the backdrop misaligned and bent. We had to keep after them for at least six months to get it fixed. When they finally fixed it, they installed the glass backwards, with the dusty side in. They scraped the paint off the surround in two places. They jammed the tray so that it would no longer fit. They also pulled the chain curtain so it no longer hung straight. They then installed the gutter supports directly in front of the window panes where they are in the way of our beautiful view! It is going to cost us another $5K to replace the brand new gutters and the soffits because of their terrible work.

I purchased a 1950's home in Alexandria, VA in 2018; one of the first steps that needed to be…read moreundertaken was air sealing and re-insulating the attic and encapsulating the crawlspace to bring the home to modern comfort and health standards. I went with Comfenergy due to their professionalism and expertise. From the energy audit and consultation (Matt), to the removal and re-installation of attic insulation, crawlspace encapsulation and dehumidifier installation (Dylan & crew), things have performed as expected over a year later. No more humidity, no more overworked HVAC, and no more mud pit under the house. I am writing this review because I had an issue with the dehumidifier that was installed (throwing an error code). I called on a Monday before a holiday and explained the situation. Comfenergy had someone (Ariel) out by Friday to diagnose. He fixed the issue, offered amazing advice, answered all of my questions, and even performed an inspection of their previous work (going as far to spot repair a few places that had weakened due to settling). This kind of customer service, over one year after performing their work, made me feel a whole lot better over such a major investment and project for my home. I believe this is one of those instances where "you get what you pay for," and Comfenergy certainly exceeded my expectations.

The technician told me that squirrels were in there at some point and we both saw the birds there now. There was a hornets nest the size of a bottle cap and some issues with the screens over the vents. He told me he could repair the holes for $25 each ($50 total), the insulation replacement would be $3300, hornets nest removal $350, and replace the screens for $600. I chose to get the holes replaced and have my pest control company disinfect and take care of the hornets nest. Got on the schedule and had a voicemail left on Friday May 11th that I was on the schedule for the following Monday and I would get a call 24-48 hours before to tell me my time block. Monday morning I never received this call and called. The nice girl that answered said she would call the technician and get back to me. Never did. As I was leaving my house for a doctors appt, he showed up and we had to reschedule. Reschedule day comes around and I got a phone call a few days prior confirming the time. It was scheduled for Tuesday May 22nd between 3-5pm. I left work early to make sure I was home. 5pm comes around and no technician. I call stating how upset I am and all i was told was to call the technician. I called left a voicemail and nothing. 7:15 he calls asking if I would like to get put on the schedule for another time. I asked if he could come Wednesday and he said he would check with the scheduling office and let me know. Never heard anything. I got home from work on Wednesday with a note saying he had left 20 mins earlier. I call them and again tell them how upset I am and she apologized (first time anyone had) and gave me the technicians number again. Called left a voicemail. No response. I just got off the phone with them and got an apology and heard that there has been an issue with the specific technician and she would be taking it to his manager on my behalf. She was very apologetic and put me on the top priority for a different day that thankfully worked for my schedule. Halfway through writing this I called them and got it sorted. When I first started I left 1 star because I could leave 0. I called bc I thought there's no way this is the norm for a company this big. My advice if you hire them and have any issues call the number, not the call center, but the actual scheduling number and most of the ladies will be very helpful.

We had a very unsettling experience with this animal control company. They sent a local contractor…read moreto our home, and from the start his behavior was odd and unprofessional. He made a big show of holstering a firearm when he arrived(showing off). During the removal of a dead animal from the attic, he handled the situation in a completely inappropriate manner and threw the animal toward us instead of disposing of it properly. This was unsanitary and entirely unnecessary. Given the nature of this type of work, I expected professionalism and basic respect for the homeowner. That was not what we received. Based on this experience, I would not recommend this company and would advise others to proceed with caution.
