I don't like giving negative feedback but I was not entirely happy with them. It took many, many phone calls and a very long time for the work to get done.

I have a second home in Lafayette California and wanted my kitchen and living room remodeled and updated. I interviewed several general contractors to perform the extensive make over and hired Fjellbo and son contractors. I am so pleased and couldn't be happier with the service and quality of these guys. I love the work and I love my new home. Thanks!
