  • The estimate process was quick but thorough. We explained the timeline the attorneys gave us, and they did their best to accommodate it despite a heavy workload.
    Description of work:
    I asked for an estimate in support of litigation with my insurance company. Not only did the representative talk us through the estimate process he uses, he also was very knowledgeable about the insurance process. Hopefully our litigation goes well--if we are awarded a settlement, we will definitely be calling Paramount back to do the work!

    Bud O.
  • Jon installed new siding to my home. The work looks very professional and it was a pleasure to work with him and the entire Paramount staff!

  • I chose Paramount after interviewing 4 window companies. I was finally sold on Paramount after I visited their office to view a sample window. The owner, Brandon, stayed with me on the process and simply did the best job of convincing me of his experience and honesty. In the end, he did do everything he said he would. All in all it was a great experience. I would highly recommend Paramount.

    Customer Colorado Springs
  • This is a contractor that we were very satisfied with. We thought the price was very fair and their subcontractors were professional and got the job done. We were satisfied with the end result.

    Roxanne D.
  • The contractor was there when scheduled (two weeks later than originally scheduled at no fault of the company due to heavy rains in this area. The company kept in contact and kept me informed about this weather delay). The installer was receptive to requests and questions and very professional. The tear off and installation when off without an issue. The job was completed to my expectations and the house looks wonderful.

    Joseph C.
  • Every member of the team was respectful and professional. Brandon was very helpful and was willing to take the time to answer every question. The crew worked one weekend so they finished a week ahead of schedule.

    Maron K.
  • First of all:
    #1 - the estimate was done by the owner Brandon, himself. He seemed very knowledgeable (and over time we learned he was indeed very knowledgeable) and very easy to contact by phone or through his office.
    #2 - The material arrived way before the job started so there would be no delays once the crew was here.
    #3 - The siding crew - Jason, Joe and Rich are company employees and work as if they have a vested interest in doing a great job. They were respectful and neat. Once the job was completed any concerns were answered immediately. For example, the painters forgot to re-attach an electric fixture, I called Brandon and the fixture was reattached within 24 hours. The siding crew would phone us if they were delayed. Actually, we really didn't need to be home for them to do their work, they only needed access to the garage.
    #4- We did a final walk around with Brandon before final payment and all of our concerns were met - he even took steps to address an area on the frame of the garage that could have been sanded before painting.
    We were very pleased with the work and will definitely use this company in the future.

  • We were impressed with Brandon, his crew, and office staff at Paramount Siding and Windows! The transformation of our 1977 home was incredible! We hired Brandon because of his company's favorable reviews on Angie's List. He did not disappoint. From our initial meeting with him until the end of our remodel project, Brandon was always professional, knowledgeable, informative, and patient. He was dedicated to making certain we were satisfied with every task that his crew performed. We are extremely pleased with the quality and look of our new siding, windows, and doors, and the craftsmanship that went into the installation of them. Thank you Brandon, Karen, and all the hardworking crew!

    Chris S.
  • EXCELLENT, EXCELLENT, EXCELLENT!! What an amazing and great job Paramount Siding and Windows did on my home! I highly recommend this company for all of your housing and/or business needs. There were two crews who came out to my home: The first crew installed my 'Paramount' windows, they were courteous and professional, AND they did not leave a mess. They also replaced a window at my parents’ house that same day. The second crew replaced all of my siding with 'John Hardy Siding'. Again this crew was highly professional, courteous and did not leave a mess. They worked on my house like it was their own house. They did not "cut corners" they made sure everything was done to perfection. Again, I highly recommend Paramount Siding and Windows for your housing and/or business needs.

  • It went very well. Paramount exceeded our expectations to the fullest. Customer oriented and satisfaction guarantee, quality assurance to the fullest and knowledgable with their product. As indicated earlier Paramount went over and beyond to ensure all our needs were met. After the vinyl siding was on the house, we experienced a roof leak from a installation that occurred 2 years prior. The roofers were indicating that the roof leaked because of the vinyl siding was not installed properly. The owner of Paramount came out on his own time and explained to us the owners of the property and to the roofers that the vinyl siding had nothing to do with the roof leaking. After a disagreement with the roofers, Paramount came out on a Sunday and removed the vinyl siding around the fireplace. In doing this it was evident that the roofers were dead wrong and the roofers were responsible for the roof leak not Paramount. Paramount impressed a lot of neighbors along with the home owners on how customer oriented with a sincere concern for the customer. I cannot say enough about this company, outstanding to the fullest. I highly recommend this company for any vinyl siding and windows, this company does whatever it takes.

  • With only having limited knowledge and this being my first experience with siding I wanted someone that could provide me with information to make the best decision. I met with Brandon O'Leary, Company owner and John his Operations Manager. We went through all the specifics of each of the products their offer and the benefits of each. I was extremely impressed with the time that they spend with me to help me make the right decision for my 36-year-old home. On day one Joe and Rick showed up as scheduled and stated the demo. Once the demo was completed and we had checked the house for any areas that need repair. They put a plan in place and competed the repair prior to starting any Hardie installation. The installation began and I know after the first day that I had the right guys for the job based on the way they looked at every little detail. They were some challenging points but they took their time and made sure that the worked was completed with the right appearance. They asked me questions on how I wanted things to look and provided recommendations based on their years of experience. They took the time every day to clean up my property before leaving for the day. The job took several days to complete and I was in contact with Brandon and Karen on several occasions for status of the job. Brandon worked with me to pick custom colors for the home and arranged to have the home painted once the installation was complete. Karen in the office provided me with all the information that I needed to understand progress while setting expectations. She continued to follow-up after the job was completed to may sure that I was extremely satisfied with the work that Paramount had completed. I would say that this is one of the best experiences that I have had with a home repair project with the several homes that I have owned over the past 40 years. The home looks great and I know that the product will last for many years. It's a great feeling knowing that your investment is well protect with a quality product and the expect work completed by Paramount Siding and Windows. I would recommend that if you looking for great workmanship for your home that you contact Paramount.

  • Incredible!!! The most professional, courteous, every detail addressed, service i have had with any company in years!! Honest, most sincere people I have every worked with, no one ever tried to sell me anything i didn't need. All details were explained to me thoroughly and to my understanding, and throughout the whole job someone from the company was always in touch with me to keep me updated on how the progress was going and when they would be there. A beautiful, professional job and personal experience! I will recommend them to anyone and everyone I know!! Pricing was better than any other bids I got too!!

    Debra H.
  • The project was quite large, and I relied on their expertise to perform the design, implementation and finish work inside and outside, which they completed in a professional and timely fashion! They remained on the job site until the critical phase was completed while the weather was good, which is not something you always see! I was very impressed with the overall experience and talent his crew possessed. Absolutely first rate! They will likely be replacing windows in the house I currently live in! I highly recommend Brandon and his crew at Paramount Windows and Siding.

    Greg N.
  • Paramount Siding & Windows was the best contractor we have ever worked with for home repairs. Our house was significantly damaged by the hail last fall and we had to replace all of our siding. Brandon came out and explained what options were available for our new siding. He listened and made suggestions on everything from materials to colors. He offered options which no other company did. We knew that was exactly what we wanted. We selected Craneboard solid core siding and also chose to replace all of the fascia. The Production Manager, John, kept us informed of exactly what they would be doing and double checked to ensure that we were getting everything we wanted. The Installers, Richard and Duane, were exceptional craftsmen. The quality of their work and their attention to detail was outstanding. They were friendly and courteous. If we ever need repairs again, we will have Paramount Siding & Windows do the work.

  • On March 9, Brandon came to our home to give us a quote. I told him we were on a tight budget, so he didn't go crazy trying to upsell the entire time. That hasn't been the case with other companies in the past, so it was a breath of fresh air. On March 10, Karen called and said they had a cancellation. She wanted to know if we were open to starting on the 11th, which I replied, Yes! On March 11, Joe showed up and went to work. He had some equipment problems but nothing too serious as far as I could tell. If it weren't for those problems, he said he would have had the job done on the 12th. He finished by lunch on the 13th. On the 17th, John came over, checked Joe's work and inquired about our experience. All in all, this was a great company to work with. Everyone was extremely friendly, professional and great communicators. We'll use them again.

  • Brandon came out and discussed the options for windows and siding. He deals with lots of different window and siding company's so that you can choose what works for your home. Not just a narrow field of products. He discussed the plus and minus of each one you are interested in. They came in some really cold weather to get the job done. They also came back to fix a few things that bothered us. The house looks so so much better. Both window and siding crews did a great job.

    Louis D.
  • Brandon, the owner of the company, came out to our home after an initial appointment was set up. He was so down to earth and professional and easy to work with regarding out siding project. We were on a very tight budget and did not have much wiggle room. Brandon worked very hard so that both parties were happy with the price and the QUALITY of the work was fantastic!!! Our siding and windows were installed timely and the siding looks so great!! Our neighbors are asking us who provided the service and are possibly going to use Paramount Siding and Windows for their siding needs as well! A GREAT company!!

  • The project went very well. I really liked Rick, the lead on the project team. We would discuss tricky areas and Rick would figure out the best option. I wanted certain J-channel and colors used around certain windows and certain peaks on the house. Rick liked it that I was going for a certain look and design. After all, this siding is guaranteed for the life of the house, so it is important that it all look right when the project is done. Rick and Dwayne brought a radio with them, so there was music going while they worked. They could not work on days that snowed. Spring snows are too wet. One night the wind came up and blew some of the foam layer off the walls. But that was easily put back up. During Spring Break, Rick and Dwayne brought their sons with them and let the young men do a bit of apprentice work. Every day, before they left, everything was picked up. Some large tools and ladders were left in the back yard. Others were put into a trailer that was parked in front of the house for the duration of the project. Trash was stored in two large bins that Waste Management picked up 3 days after the project was done. The Waste Management driver who picked up the bags did not like the fact that one of the bags. It made picking it up with the mechanical arm difficult. But he was skillful and did no damage to either the tree or the bushes that were in the way. Work began on March 18, and ended on April 4, 2015. The team worked M-F and generally from 8 AM to 5 PM. (Although they did work one Saturday (April 4) for about 1/2 day to complete work that rain halted on that Friday.) There were two snow days during the project. So actual number of days for installation was 12. (I estimated that it would be at least 10.) Overall, the project went smoothly and now I have the newest house in the neighborhood.
