Having Paramount Siding and Windows do ALL OF OUR WINDOWS was wonderful!! We have had them do a few different jobs for us and have never had a problem?? Always willing to do the extra's and have a professional attitude with the whole experience. Brandon the owner is a pleasure to know, he has the experience and customer service. He strives to have a successful company and cares about the product that he sells to his customers. Once you meet him and know the story behind his success, he is the hardest worker I have seen in a young man in along time!!! Would I recommend him to others, why not!!!

Cheri P.

Great company, very pleased with the windows. We love the look, and they fit perfect. The crew was very friendly and professional. We had six windows to replace and they did it in a timely manner. The crew cleaned up after themselves and it looked like they were never there.

Mike S.

I had Paramount install new vinyl windows in my home. I had a fantastic experience with the salesman and the installers. They were very polite and courteous and knowledgeable and I would use them again.

Jackie N.

Paramount Windows installed 17 Sunrise windows and a patio door. Some glitches in ordering and installation, but all were promptly resolved. We're happy.

John S.

I'm extremely happy and satisfied with my new windows. Installation was quick and painless. The installer, Chris, answered with expertise, any questions I had and he was courteous,respectful and he cleaned up any mess as if he wasn't even there! I would recommend this company as I am planning on having other windows replaced. Thank you.

Faith A.

Very happy and satisfied with the work of Paramount Windows, from start to finish. Would recommend highly.

Colleen S.

I was generally impressed with Paramount. John Kinyon, the sales agent, was very well informed about the product and fair with the pricing. I think that the product is very good in quality, both the windows and doors. The window installers, who were subcontractors, did a good job, but could have done the weatherstripping could have been cut a little more precisely, as this resulted in cold spots/drafts that are energy auditor pointed out to us. Paramount did come free of charge and fix the problem. Overall, a very solid company. I would recommend this company to others.

Jeff U.

Overall, my experience was quite excellent. I think the windows were quite good for the price, and in total I am happy with me purchase.

Cyle F.

Will S.

Linda D.

They say what their gonna do and they do what they say they will do. The windows were up to my standards of craftsmanship. Sales crew threw instillation crew met all your expectations. I am also at this time looking at them possibly doing my siding and I would recommend.

Greg L.

Paramount was fabulous to work with. From our salesperson to the production manager to our install person, everyone was knowledgeable, kind, on time, and professional. Installation was smooth, even in the snow. We'd recommend them to anyone.

Jacqueline H

I was very happy with installers. They were like younger sons. They were family men very friendly. They worked well with other installers no conflicts occurred. Loved the windows look fantastic. Can't wait to get my first electric bill. Tyler was very professional. One bad think was Salesman was kind of pushy, Would recommend!

Angela G

I initially posted a bad review due to the many missteps this project took. However, after the install finally took place, Brandon O'Leary, the company's owner called to talk with me and apologize for the problems. Because of the 6-month process, he wrote off the remaining balance. At the end of the day, problems will arise and it shows his character as a person and business owner to do what was right for the customer. This kind of integrity is not often seen today in business.

Sharon P.

I had a great experience with this company. I love my new siding thank you Duane for doing a great job.

Caitlin O.

This company is very customer oriented. They are in touch with the customer at every step of the job, before, during, and after. They are very friendly and easy to work with. Always answering all our questions, so we have a complete understanding of what will be done. I highly recommend Paramount Siding & Windows and will be using them for future projects. They are a company that truly earns your trust and satisfaction.

Paramount Siding and Windows- They showed true customer service and they made sure everything was built to perfection. I would highly recommend this company to do your windows and siding.

Dixie M.

Work completed on time Good cleanup after project completed Kept informed of project.

S.K.

I hired this company even though they were not the least expensive because I like the process they used to install the windows. I have had other windows replaced by other companies and they leaked. They only thing I didn't like was that the workman showed up about 5 and didn't leave till almost midnight.

Carol M.

The overall job was GREAT. Their installer was wonderful and will mannered (Good Home Training) I'm sure. The job was done at my rate and time. The best part was that you would never know the installer was even there. Everything was keep clean as the job was done. Also the office keep in contact with me before the job was even started.

Samuel R.

Had a great experience. 6 windows were replaced downstairs. The installer was nearly nonexistent and did a great job! Can't wait for the cold now!

William Z.

I highly recommend this company for your replacement Siding & Windows. We do great work 🙂 We cover from Colorado Springs, CO all the way up to Casper, WY.

David did a truly professional job of installing nine windows including old window removal and cleaning up after each day’s work. Totally satisfied and would recommend this company and their product to anyone.

Virgil P.

Paramount did an awesome job with our new windows. Our house is noticeably warmer, and the craftsmanship was great. They're much better than our old windows! I would recommend Paramount to anyone!

Chris H.

Great company to work with from start to finish. Everyone was friendly and courteous. I'm glad we chose them to do our window replacement.

Christopher B.

Working with Brandon and Paramount Windows and Siding was a very positive experience. Brandon was always punctual with any appointments or phone calls and office staff was great about keeping us informed of timelines, etc. for our project. The work was completed just as planned for and promised. We were very satisfied with everyone involved.

J. A.

I had a great experience with them - 11 windows installed - price the most reasonable I was able to find in this town - with a warranty - getting the windows here took a bit of time as the manufacturer was backed up but I was in no hurry - presentation is good, workmanship is good - were installed in my rental property and they were in and out in a day with no disturbance to the tenants. Being an older home the old windows were 'glued' to the edges so there was damage done there when they were removed, which couldn't be helped and that is on me to fix. Otherwise I would recommend at least talking to them.

S. Holmes

Brandon is a really awesome guy, loved the customer service, and the quality of work was second to none. Would definitely recommend to friends and family!!

Stan W.

Paramount installed 7 windows in a home I just bought in Denver. I am very pleased with the way they look and I can already tell a difference in the draftiness of my home. Paramount was with me every step of the way. I couldn't have asked for a better experience. I will be recommending Paramount Siding & Windows to everyone I know.

K. Jordan

We had PARAMOUNT change out a 10 yr old slider to a beautiful and high quality french door (1 side operating). We love it and their service was exceptional. As a Kitchen and Bath professional I now recommend Paramount to my clients for great service and great quality products!

I really love Paramount Siding & Windows. I'd much rather give my money to a small business like Paramount than to a large corporate company. Everyone is so friendly and helpful. My windows look amazing! I have already noticed the difference in my home temperature. Thanks Paramount!

Thank you Paramount for my new windows. I really appreciated the salesman Brandon he lived up to everything he promised. I highly recommend this company and will use them again in a few years when my siding needs redoing.

Dexter

Paramount replaced all the windows in our home. Brandon was on time for our free estimate. He explained the entire process and answered all the questions we had. Thank you for giving us a great experience.

Daniel

Paramount went above & beyond to install our new Sunrise Window. We will use this company again in the future.

Martha

Paramount installed fourteen Sunrise Windows. The new Sunrise Windows were framed with new oak trim to match the existing wood work. Kevin and Brandon have always returned calls and stop by to check on the work. Thank you to Jeremy and Brian for a great experience and for being considerate to our home.

Robert

Paramount installed a new Fiberglass Door with side panels and new Sunrise Windows. Kevin and Brandon were great to work with, and very knowledgeable about their products. The installers Jeremy & Brain were on time, polite and very diligent.

Carol

Paramount took out the old windows and then replaced them with new Sunrise Windows. They wrapped the exterior trim so we won’t ever have to paint them. Paramount cleaned everything up and hauled away all the trash. The workers were on time, polite, professional, and were pleasant to be around. Paramount kept right on task and they showed me how to work the windows. They answered all my questions, and thank you to Jeremy, Bryan, and Chris for a wonderful experience.

Juanita

We are very pleased with our experience from Paramount. Beginning with Brandon to the completion, everyone was very professional, tidy and courteous. Paramount is truly an expert in their craft. We are so pleased that we are having them back to replace a door and screen doors.

Jay and Cindy

I could not have asked for better service and quality than we got. The materials are excellent and we are well satisfied. The service after the install from Paramount was great, they are always checking in to see I am still satisfied.

Dean and Jean K.

Paramount came and removed my kitchen window and replaced it with a new Sunrise Window. The carpenters arrived on time, worked continuously on the window and cleaned up everything.
