Wonderful work, great guys, they cleaned up after themselves amazingly and the price was excellent! I'm so happy we did this and can't wait to see how much better this house will be at retaining the cold/heat moving forward. We had no insulation in most of the house. Daniel, Branley and their team were amazing, so friendly and they explained everything to me in great detail. Highly recommended

Louis, his son , Vinny, and the crew completely transformed the house in just 1.5 days--insulating everything from the walls to the rim joists and crawl space. Louis came by to look at my house, used thermal imaging and brought pictures to show me what to expect. Very thorough, knowledgable, trustworthy and truly helpful. Honestly, I was a little anxious about them drilling into the mortar of our brick exterior, but decided to trust the process. Their work is seamless. I can't even see where the holes were! They left the house spotless, can't even tell they were here. We felt the comfort levels improve immediately. Highly recommend this team if you want honest, expert work from people who actually respect your home and know what they're doing!

Triple H Insulation

My reason for bringing Triple H in was the 3 bedrooms we use that myself and my children sleep in…read morewere freezing at night. I knew the insulation in my attic was a mess and antiquated as my house was built around 1970(average for Long Island). One of my children's bedroom is over my two car garage and I had no idea what type(if any) of insulation was in the ceiling of the garage, under my daughters bedroom. My home is a splanch so I also have a half bathroom in the rear of the house, off the kitchen which was also always very cold but less worrisome since nobody slept in it. Chris and Kyle came in to do an audit, they are were professional, honest and efficient . They quickly identified the spots I mentioned and found even more spots where they can make a huge difference. We sat down and went over the options financially, how long it would take, if there would be holes in the Sheetrock etc. There was never any pressure and they answered all our questions professionally. He assured us that beside the garage, there would be no holes anywhere (in the garage they would spackle all the holes so all I had to do was touch up )and all the rest of the work would be from the outside and the attic. I have twin 2.5 year olds so timing was important, they promised me it would take 2 days max and they would even do one day on a Saturday to help us out. Install day came and they delivered everything they promised, and more! Their crew was professional, timely, efficient and left the place as clean as it was when they entered. To top it off, Chris and Kyle sent two crews to my house so they were able to get the job done in 1 full day. Chris and Kyle also personally stopped by to make sure the job was going smoothly. We then could not wait to see if we would "feel the difference". It took one night for us to discover the result was even better then we imagined. My master bedroom, which I had spent the prior 3 years(since I owned the house) freezing in at night in the winter, was actually so warm that I woke up in the middle of the night sweating and had to remove my shirt. Since then, my wife and I have been running the ceiling fan all night (even when It was 3 degrees outside with the windchill). We were used to going into my daughters room when she woke up, and feeling the cold. On most nights the thermometer in her room would read 63/64degrees, even though the thermostat in the hallway was set at and reading 70 degrees. Well we opened the door and couldn't believe it, it was warm!!!!! The thermometer was actually reading 72 degrees. We truly recommend Chris, Kyle and everybody at Triple H. They did an amazing job and highly recommend them!

This is by far the worst company I have had at my home for insulation. In December 2025, I had a…read morevisit from Brian Edgar. Brian came in with a Health Homes booklet chock full of things that could be done. He then identified key areas that need insulation. He found areas that no one else did. I was sold. He told me about the PSEG programs he could get for me. than I asked him about NYSERDA because I was confused about the programs as I called from NYSERDA. Brian the looked at me and said "I think you're trying to play both sides". I was shocked, both sides of what. He seemed angry about NYSERDA so I called and put them on hold, waiting for Brian to contact me again about PSEG. When When Brian left he assured me he could get me in the PSEG program and to give him a couple of weeks. After a month I called him and he hadn't don't anything, he said "oh I remember you, the PSEG stuff". He said he would contact be back. He never did. this time I called the office hoping to speak to Jill but the woman that answered said she would give Brian the message. I never heard from Brian again, I have NYSERDA still waiting and this company was a huge waste of time. So today October 13, I received a text from Crystal about a recent (December) visit with your Comfort Consultant to discuss insulation and how the visit went. She even asked if I'd like to move forward. How exactly was I supposed to to that when your Home Comfort Consultant abandoned my proposal and did nothing but get angry over the various programs. The guy is a nutcase. And now I am angered that I get a random text from a company that did not follow through on sh*t. Take my advice and and don't let Brian through your door...

Long Island Power Solutions

After talking to a number of companies, I contacted our real estate agent from 18 years ago, Jeremy…read moreZucker. He recommended Long Island power solutions and my representative the wonderful David Kowalsky. One of the scam companies I had spoken with and never signed a contract nor indicated I wanted to move forward - after almost a year- out of nowhere, applied for a permit to put solar panels on our house. We live in Yonkers. I was horrified! I had no communication with them and they did this behind my back. It took a couple of months to straighten this out because a fine had to be paid by them to remove the permit. We first needed to put a new roof on before putting solar. It was such a scam and the company was located actually out west. That's when I called my real estate agent Jeremy and asked for his advice because he went solar and was extremely happy, and he had done all of the research. We took Jeremy's advice and we are thrilled! From the very beginning, it was a pleasure working with David Kowalsky. Not pushy. Very easy to reach at any time. He answered all of our questions, very straightforward and was always there for us. He searched around to find the best financing and any of the New York incentives. We first had to get a new roof on our 100 year old house. Once we got our new roof, we moved forward with Long Island power solutions. Everything went smoothly with them and they made the process actually enjoyable. Once they came out to install the panels on our 100-year-old colonial house, we didn't even know what they were here. It was very smooth, and they finished perfectly within the day and put up protection against the squirrels and raccoons of which we have a lot. I was afraid of them getting on the roof and destroying things. Where we live, we have a lot of wildlife. When they finished that day, they left our yard cleaner than when they arrived. We went online finally last September. We have the Ephase app on our phones and enjoy enormously, seeing minute by minute how much power we are drawing in from the sun. We even get power on cloudy days. Like everyone around the New York City and Westchester area, we have been stuck with consolidated Edison, which is a monopoly and for profit. Our bills have been jumping sky high and ConEd has been pocketing huge profit from everyone in this area that are stuck with them. We are so happy to have solar! We have only great things to say about this solar company. We have only had excellent interaction with them and the panels are working great and our representative David Kowalsky is always there for any questions that we have. Highly recommend!

I chose this company over several other local installers like Momentum, EmPower, and Green Logic,…read morebut ultimately had a mixed experience. While the sales team was professional and assured me they had extensive experience with the strict solar regulations in my area, there was a significant gap between those assurances and the actual permitting process. I was initially told I would only be responsible for a specific village application fee (should the village deny the proposal). Unfortunately it was denied, I was charged $2,500 for various fees including site surveys, administrative costs, and architectural drawings. The project unfortunately did not work out, and the most frustrating part was the permitting and billing hurdle. I had to spend a considerable amount of time negotiating with their customer service team to lower those initial fees, eventually settling on a $1,000 charge for the work performed. They seem like a decent local company, but their internal processes--especially within the permitting department--need better alignment with the promises made by sales. My advice to others is to double-check every detail in your contract before moving forward.

Sherlock Home Inspection

While the office is in Garden City, NY, wherever your potential new home is - Long Island, the five…read moreboroughs, and Westchester, Rockland or Putnam - you will want Sherlock Home Inspections to perform your home inspection. His friendly demeanor set me and my husband at ease right from the moment we met. He introduced himself, told us that he would be about an hour and upon completion, would go around and explain any concerns. Well, Mr. Marino, who is owner/operator was definitely focused and took more than an houqqr in the inspection part alone but we never felt rushed or as if he was being inconvenienced. He then escorted us from top to bottom explaining any concerns, told us his recommendations to curtail future issues with certain items and/or possible solutions to solve issues with actual concerns. We had our report within 10 minutes of the actual conclusion of the inspection and went over what we needed to keep, what the lawyers needed to see and what the mortgage company needed to see. The care and concern that Sherlock Home Inspections showed made me feel like a family member was doing the inspection and I felt he was genuinely concerned about me and the home I was looking to purchase. Definitely contact Sherlock Home Inspections for your home service needs!

Being a single woman I know nothing about the mechanics of a house. Marc took alot of time going through each and every nook & cranny. He then took me outside & spoke to me before going thru the house again, this time with me in tow. He explained things that were going to need replacement at some point, took the time to explain to me how things like the boiler & hot water tank work (yes, I'm that clueless!) & noticed defects in areas I never would have thought to look (like between window panes!). Marc was personable, thorough & professional. I will highly recommend his services to any one who asks! Thank you Marc
