Residential Contractor Broomfield – Grein Custom Homes

See What Our Clients Say

  • Richard Knudsen

    I contracted with Ken Grein to build a custom home for me in Thornton. At the time I was still living in CA during the build. Being over 1,000 miles away many thing were handled via phone calls and emails with pictures. I met with him just once or twice during the build to finalize some details and have input6. Even though i was far away, I trusted him completely. I received invoices as they came up for payment and copies of all payments and monies spent. Everything was detailed down to the penny. I couldn’t have picked a more trustworthy, honest person to deal with. I felt totally comfortable with him in charge and was extremely pleased with the outcome and the build of my home. If any issues arose, he handled them quickly and he stood behind his work. He made repairs and touch ups as I requested and never complained about anything. I don’t think you could find a more honest, trustworthy person as a builder. I highly recommend him to anyone thinking of doing any construction or remodeling work. You won’t regret it.

    Ken Grein and his team built our home and helped make our dreams become reality. Ken was great to work with throughout the process. From the time we discussed our plans, received bids, started the build to completion, the entire process was perfect. Ken is great with his communication, project management skills and there were no surprises along the way. If you need a great builder, one that you can trust, rely on to do what is right and ensure timelines are met to stay on track, Grein Custom Homes is the right choice. I would highly recommend Ken and if we ever build again, I would not use anyone else but Ken and his team!

    Having used contractors before, my wife and I were surprised at how different Grein Custom Homes was from the others. In the massive remodel and upgrade of our kitchen we found Ken to be friendly, knowledgeable, timely but more important clear in what needed to be done and how best to accomplish our objective, a gourmet professional kitchen. We were worked with rather than against in picking details, expression of our views and desires, the levels of quality and layout to be achieved. Ken helped resolve the problem encountered by surprises in the walls.
