1. Job was about a year ago. We had a pretty long “wish list” of repairs and installs. All jobs were done very well and to our satisfaction. Everyone was professional and did great work. We’re very happy with 1Core Construction and would use them again without hesitation. And recommend you to use them too for any work you need done. 2. Early spring 2022 was a job changing a wood 10x10 deck to a 10x12 composite deck. 3. About June of 2022 repairing the wood frame around the garage doors. 4. End of July 2022 bathroom remodel. And I love it. Everyone that has come to see it is really impressed and jealous. Julian is great to work with. Makes great suggestions and listen’s to what you want done. I will definitely be giving him more business. And a neighbor asked for his contact info.

Julian and his crew did a fantastic job replacing my sliding glass door. It was perfectly done, and looks so good I do not want to put the shades back up! Julian's expertise in construction is unmatched. He knows all areas of the field (I am consulting with him on other repair issues), and is clear and concise in his appraisals. I knew what to expect, how the process would unfold, and how long it would take. His team was extremely professional, both in craftmanship and artistry. I think they have all worked together for years making it an experienced and potent workforce. All delightful too! Ellen Lavelle

My husband and I have used Julian on several different homes for just about everything under the sun. He never ceases to amaze us. He is our go-to contractor whenever starting a project and out go-to contractor whenever someone needs a recommendation.

The nicest crew you'll ever meet. They did not rush us and gave us time to make choices for items we wanted. They Understood our budget and stayed well within our goal not maxing us out. They were on time everytime. Went to great lengths to Explain in great detail how they will work. What their doing. Why its being done certain way.etc... Left behind a very clean work site. Everyone was a Fast worker actually working. Even took time after they job to grade the land where our basement is; so the rain can go down the hill and not flood our basement. They hauled away old gutters and shingles and put up new ones that looks AWESOME! Never had to worry about trash. We have 6 kids and 2dogs. They took every safety protocol to make sure they were safe before, during, and after the construction when installing roof as the kids were going and coming back from school. We had a hole in your ceiling and it has not leaked an since the work has been done. They sister joist the beam for extra support and put down new ply wood vs. Just going back over the the old one and calling it a day. They did the job right the 1st time so we can live sleep in peace knowing it's mold free. They got to the source of all our problems. We couldn't be more happier to find and use their services and will call them in future when needed.
