They were also slightly misleading about the price, initially suggesting they could give me a break if they reviewed photos, then sending a request for a deposit of $300, which looked like the 'break', but turned out to be only half the bill--balance presented after the work was done. But I blame myself for not being more alert.

The manufacturer honored the warranty and sent me a replacement unit at no cost, which confirms there is a legitimate issue. Despite this, the company has refused to come out and install the replacement or address the problem. Communication has been poor from the beginning. Representatives have been dismissive and unhelpful, and at one point I was hung up on. Since then, my calls have gone unanswered. I was ultimately told this decision came directly from the owner, which is even more disappointing. I will continue escalating this matter until a resolution is reached. I expected accountability and basic customer support, but instead got the opposite. I would strongly caution others before working with this company.

Every contractor who came before seemed to patch a different area, but the problems always came back eventually. Goldenberg Roofing BK broke the cycle. After inspecting the roof, they showed us several areas where water had been ponding for a long time and explained how the existing drainage layout was contributing to the deterioration. The project involved a full tear-off, new flat roofing system, updated flashing, and improvements around the drains. The crew worked efficiently, kept the roof organized throughout the project, and provided updates along the way. We've been through several major storms since completion and the roof has performed exactly as hoped.

I chose Mazgan to resolve a problem with my Navien combi boiler, and I am very happy that I made…read morethis choice. The problem turned out to be much more serious than initially expected, and resolving it required several visits by Mazgan's technicians. Although the repair process was more involved than anyone had anticipated, the company continued working on the problem until it was fully resolved. Throughout the process, the technicians proved themselves to be responsible professionals who worked hard to solve the problem. Mazgan arranged for the necessary parts to be supplied by Navien. In several cases, obtaining those parts at no cost required Mazgan to negotiate with Navien on my behalf. The company was also very accommodating regarding the overall cost of the repairs. In the end, Mazgan proved to be a reliable company that stands behind its work and can be trusted to see a difficult project through to completion.

Then Mark said it would cost $3000 to get up and running with new wall unit install. When I complained, they said they would work with me. (I expected $2K to finish). When a used unit arrived on site for replacement, he instead sent a bill for $5500 to install, trying to weasel $8000 out of me to change out a simple wall unit 7' high on a wall. He then knocked it down to $4300. Still ridiculously HIGH!!! They add in line items like $500 crane fee for their lazy asses to lift the 15 lbs unit in the air. They originally tried to charge $225/lbs of R410A freon. I could go on and on. In the end they left me hanging but thank God they did. I called another company that charged me $2600 total to install a brand new unit ($700), with 11 lbs @ only $95/lbs of freon fee and none of their predatory fees- just an hourly rate. Mazgan is so unscrupulous. I hate vendors like this. STEER CLEAR. I cannot express this enough.

The job was…read moredone well, in a reasonable amount of time...But they left over 20 bags of debris in the apartment! Unbelievable. I called to ask about getting the debris removed, and Frank said that they do not remove debris! What contractor leaves all of their debris on the job-site? Extremely unprofessional. He did not even offer to remove the debris for an extra charge, he just said that they do not take away their garbage. I have hired many contractors and been hired as a contractor, and I can tell you that this is unheard of. Even the super could not believe that they refused to remove their debris. Maybe they would be OK for a small job, but I would never recommend them for any type of larger job.

The next day I inspected the attic thinking that maybe the solar panels installed two years ago may be the cause. To my surprise and relief the cause was a missing plastic cover that was on the roofs powered exhaust vent. It had blown off during Fridays storm. Luckily my tenant had stored the cover but did know what it was. The vent with the cover on looks like a mushroom. On Sunday, I used Angie 's list to located a Staten Island roofer since my Brooklyn guy had not yet called back and I didn't want to risk another rain storm. The first contractor that called was already talking about replacing the exhaust vent at about $1600 for the job I cut him short since I only wanted a cover replaced. I said this is not looking good . Good bye. About 5 minutes later Marke calls me I got lucky, real lucky in finding a guy that did not try to cheat me. I told him all that was needed was to replace the cover. I texted him the photos of the cover. He stated that he could possibly fix the cover once he takes a look at it. It may be hard to find a replacement. At 10am he arrived at the house with his father. (Once he said that was his father, I knew I had the right guy) He inspected the roof and confirmed he could do a decent repair. He showed me pics of the roof vent. No need to change it. He used metal strips and screws to attach the cover. Then he placed ice/water shield and adhered it to the cover. He took pics again after the repair. The price was very reasonable The honesty was superb The time arrangement could not have been better. I paid cash and he later emailed me an invoice as I had requested. He is a good man who works with his father and since he did not steer me wrong, I decided to give him an excellent review!! I hope you call him if you ever do need a reliable and honest roofer. By the way, my Brooklyn roofer did call me back and confirmed that he would have done the same.
