    Michael and his team were excellent! They helped us resolve structural issues with our joists,…read morebeams, and outdoor stairs. They did the work in half of the time that others quoted us and gave us a 30 year warranty!

    Michael showed compassion…read more I called Michael after I was a victim of a scam. A fraudulent waterproofing company that I unfortunately hired. They started the escavation and then half way through started trying to extort more money out of me. It was at that point that I made a decision to rid them from my property and accept the loss and damages. With my house now exposed to the elements and in imminent danger of collasping. I needed to find a reputable company fast. I called Structional Engineering and Design and spoke with Michael. He came out the same day to survey the area that had been partially dug out by the scammers. Due to the urgency, Michael got me on his schedule and started the work the following week. When you are going through a devastating and life-changing time. You need a compassionate and meticulous group of individuals working for you to restore your home. You can rely on Michael for prompt assistance. Michael and his team worked from early morning into the nighttime hours completing the escavation and underpinning. It was a big job and a lot of hard work. All of the guys were professional, hardworking and did a wonderful job restoring my deck after the escavation. Michael kept me informed and explained each step to me. From begin to end the Michael and his guys were simply top notch. From the start with Michael's honesty, fairness and transparency was a level above everyone else I'll had dealt with. The only thing better than the quality of his work is Michael's character. They even hauled the tons of dirt and rock with no extra charge! I'm very happy I found this company to do business with. It's been almost 4 months and I have not had a drop of water in the basement and it feels great not having to worry about it. What began as a nightmare was soon met with sit back and relax, WE GOT THIS!!!!!!

    A review I left on yellow pages in 2008:…read more http://www.yellowpages.com/newtown-square-pa/mip/cygnus-environmental-service-1383967 Use at your own Risk. Prices from Cygnus were the cheapest I found for duct cleaning. That being said, I think that was the only bright spot of this company. I had my ducts cleaned and it basically made my whole house dusty and floors dirty around the vents. The service is not as thorough as I liked it to be. I thought that all vents would be taken off to render the service, but it was not done so. They had a tube/device the size of a brakeline (on car brakes) that would fit throught the slits on the vents. They assured me that this would be enough. Looking at the vents from the outside, it definitely could have been better. The company pride itself as being a part of the National Air Duct Cleaners Association (NADCA) and follows it's guidelines for cleaning, but I guess removing vent covers to clean is not a requirement. After the service was done and I paid, I had a problem with my unit (fan constantly on) that I asked to have one of the guys sent out again to take a look at it. The owner asked me if everything on the thermostat says off. I tell him, "yes." He then tells me that it might be another problem with the thermostat or the unit that he and his guys would not know how to fix. I tell him it might be something small or one of the guys flipped a switch that we are unaware of. Well, basically he tells me it's my house and I should know what's wrong with it. He got irritated that I'm asking for him or one of his workers to come look at it. Keep in mind that the one of the reasons I hired this company other than price is because they were local. Long story short, he tells me to call him the next morning. I ask him, "When?" He tells me, "Anytime," but I knew in his voice this was not going to happen. I finally figured out the problem with the fan being on and there was a switch on the unit. I called the owner the next day to tell him no need to send anybody out. He never picked up his cell phone and never returned the call. Very unprofessional and needless to say, I will never use Cygnus again.

    Cygnus came out to clean our ducts today. Couldn't be more satisfied, their technicians were on…read moretime, polite, and efficient. They completed the job in the estimated time, and did a very thorough job. I would recommend to anyone.
