Clayton and Josh were amazing. Attention to detail, personable, and professional and they got along with our dogs which is great haha. Didn't leave a mess, and did super clean work. We have had our windows and siding done by Boulder valley siding and windows and we couldn't be happier!! My house went from 80's to modern and it's beautiful. Thank you so much for everything!!!

I'm so happy I chose them to replace all the windows in my house. Clay is so pleasant to work with, and Clay and Josh made what seemed like it could be a miserable couple of days much easier than I could have expected. They're very detail oriented and made sure that every aspect of the job was done in a way I was happy with. Plus, they carefully looked out for my dog the whole time. If they did other work my house needed, they'd be at the top of my list to call!

The Alcoa siding on the house I purchased is starting to peel badly. The siding has a lifetime warranty. I contacted Boulder Valley Siding in July, 2016 as they were the installer in 1996. They confirmed the installation but told me rather rudely that they can't be bothered with looking at this. I have since tried to work with the manufacturer of the siding product, who is denying responsibility. What is the point of having a lifetime warranty when no one will help? I have called Boulder Valley Siding to at least get a statement from them on the product and their installation to forward to Alcoa... still waiting.

I would not recommend doing business with Boulder Valley Siding if you expect any service after the initial installation of the product. I purchased windows and doors in 2009. The building has settled and the doors are all out of whack. I attempted to call the Boulder Valley Siding numerous times (since they are the installers of the doors and I figured they would be the best fit to potentially fix this issue). Every time I was told I would hear back. I March of 2016 I was told they would come by the following day. Again, I heard nothing. I called today 10/18/2016 and again asked if they would like the opportunity to fix the doors, I was treated very poorly by their phone representative. I told them I would look elsewhere. Their customer service is severely lacking. If that is important to you, look elsewhere.

Frequently Asked Questions

Yes, multiple customer reviews reference siding projects completed alongside window work. Ask about available siding materials and trim details for your home.

Timing depends on the number of windows and site conditions. Some reviewers noted efficient, tidy multi-day projects; the company can provide a more accurate timeline after a walkthrough.

Several reviews mention clean work areas and careful protection of the home during projects. You can confirm specific cleanup steps and disposal before work begins.

Experiences appear mixed in older reviews regarding aftercare and warranty follow-ups. It’s recommended to discuss your situation directly and review manufacturer and installer responsibilities.
