Testimonials

"Hygge Haus has done a few projects for me and I can’t say enough about their professionalism and the quality of their craftsmanship! Neal has transformed an outdoor patio into an oasis, installed windows, and done some general handyman work for us that was second to none. I highly recommend Hygge Haus!"

"Neal was awesome to work with. Very responsive and professional. He made sure we were satisfied with his work and it was all done skillfully. Definitely recommend him."

"Neal and his team did a great job on our project, which involved replacing a whole house of windows (with all new interior and some exterior trim) two new doors, siding repair and replacement, removal of a chimney stack, and overseeing all new gutters and a whole house paint job... Nothing but good things to say. We are thrilled with the outcome, and, dare I say, even enjoyed the process."
