INTRODUCING

HIGHLINE

by Mile High Designs

Here at 5,280 miles above sea level, we all love our Mile High nickname. Maybe a little too much. We know our clients love to refer their friends and family to Mile High Designs and we don’t want anyone to confuse us with other less than stellar Mile High service businesses. So we’re introducing a new name and online look with Highline. Don’t worry, we may be doing business as Highline but we’re delivering the same award winning service you’ve come to expect over the years from Mile High Designs.

WHO WE ARE

As a local family-owned business, Highline by Mile High Designs started small in 2005. With each completed project and satisfied client, our business continues to grow but we still think and act small. And that’s the key to our success today at Highline by Mile High Designs. Using a small number of trusted employees, trade partners and suppliers, we have confidence that you’ll be just as satisfied as our past, and oftentime repeat, clientele.

Highline is fully licensed, fully insured and trained in EPA Lead Safe techniques to protect your family. We maintain an A+ rating with the BBB, are a recipient of the BBB Gold Star Certificate and are a Best of Houzz service provider. Call or email for your free design consultation and we’ll give you a copy of our extensive reference list and credentials in person. 

We serve a large portion of the Denver metro area and the mountain communities along Hwy 285 and I-70. Not sure if that applies to you? Just drop us a line and we would be more than happy to let you know if your project falls within our service area.

Testimonials

Don’t take our word for it – here’s what our clients have to say:

We did a lot of research on all the organizations and selected Highline based on recommendations, BBB ratings and most of all on the personalized involvement by Ray. Ray’s willingness to come back several times as well as his creativity in both design and color selection made the decision even easier. Beyond the creativity and involvement was the exceptional work ethic and professionalism of the construction crew. In the construction industry it is unusual to find individuals that start when they say they will, work until it is dark and beyond and deliver a quality product that exceeds your expectations. The attention to detail was exceptional. As homeowners, one of the best decisions we have ever made was selecting Highline for our home improvement project.

Ray and the crew from Mile High Designs are amazing! I would not go with any other company!
Ray has done a master bath remodel for us and now a kitchen remodel and both jobs were beyond expectations! The quality of work was exceptional and the kitchen was done ahead of schedule…something that never occurs and was truly appreciated!! Ray is great about giving you ideas about what you can do, where to go look at fixtures and samples of things and where to find the best quality for the right price. This is most helpful for those of us who are unsure of exactly what to do or have trouble deciding! Next on the list is to replace our large above ground deck and maybe add a permanent covered structure. After seeing all the photos and in person work that he has done…I wouldn’t trust anyone else!!

We used Highline to remodel our kitchen last year and because we were so impressed, we had them back this year to build a deck in our backyard. I could not be happier with the quality of work, the professionalism of Ray and his staff and how much they cared about the projects they worked on.  They were very helpful in providing advice on design elements and constantly communicated about everything through the duration. They developed a timeline and stuck to it. We bid out both projects and Highline’s pricing was competitive with other bids from comparable companies. We are planning on bringing them back again this fall to expand and remodel our bedroom closets.* I would recommend them to any family member, friend or anyone else. We are very impressed and everyone that comes over compliments us on the kitchen and deck. 

*We did go back and remodel their closets!
