I messaged this company through their website, but never heard back so I called them, Luis answered, and he was in my area, and stopped by within 15 minutes. I liked him, we chatted, I showed him my fence and he gave me two verbal numbers depending on much of the fence we decided to rebuild. He then said he's send me over the actual quote with a couple of pictures of options, so I could discuss with my neighbors. And then... nothing. I never got the quote or pictures. I send numerous text messages asking nicely for it. I called and left him a voicemail. I sent two emails through the website. Someone on Facebook who claims to know him well even supposedly messaged him on my behalf. Still zero reply. This person needs to go and take a simple course in client management. Why bother coming to my house, wasting my time if you 1) seemingly don't want to do the job and 2) can't even manage the decently a reply. I even point blank asked, if you don't want to do the job, at least just TELL me so I know. Zero reply to any attempts to make contact. I was going to hire them to do the job. All it would have taken was a REPLY to any of my attempts to contact them again. Maybe your luck will vary, but 1 star for this utter waste of time.

Every person who walked into my home, has worked with Travis for the last 10 to 20 years. That made me very trusting of who was in my home when I was there and when I wasn't there.

We can't believe this is our house! We've had a couple of friends hire him now to do their projects! Travis walked into our patched-together 50 year old house and understood our vision for opening up the floor plan and letting more light in. He worked within our budget to draw up a quote that met our vision, while also recommending items that could easily be isolated and saved for a later project date without having to re-do any of this initial work (like refacing the fireplace, re-doing the back patio). He was patient and helpful through the architect and permitting phase and had great recommendations for local cabinet, tile and plumbing stores that allowed us to get great quality finishes within our budget. Every sub-contractor that he brought in for specialized pieces like our master shower tile, shower glass, flooring and insulation were friendly and did absolutely top of the line work. He is also very clever at figuring out solutions to curveballs that our house threw and could take our crazy Pinterest pictures and piece them together to build custom solutions like the bench in the master shower. Overall our project included a major overhaul and upgrade to our electrical panel / electrical service to the street, major plumbing upgrades, new windows, a master bathroom addition and a complete interior paint/flooring refresh and remodel including a complete kitchen remodel (with removing load bearing walls to create an open concept) and hall bath remodel. Our house of 16 years is now a sturdy, safe home we can spend the next 50 years in - Travis didn't cut any corners and understood that this needs to be our dream home that will last "generations" as he put it. He's an honest guy with old fashioned values and you just won't find a better team to take on your project.
