"Cesar and his team at Koritas did an outstanding job transforming our yard from an overgrown wilderness to a beautiful, functional outdoor space. They installed turf, cleared and leveled the yard, transplanted plants, and resealed our flagstone pavers. Cesar was meticulous with every detail, including aligning every turf seam perfectly. The team was always on time, reliable, and even finished ahead of schedule. Pricing was fair and competitive, and after waiting a little while to post this, I can confidently say everything still looks perfect. Cesar was a pleasure to work with — patient, communicative, and clearly proud of his craft. I would hire Koritas again without hesitation and highly recommend them to anyone looking for high-quality landscaping work."

"I recently hired Iconiq Construction for my bathroom renovation, and I couldnt be happier with the results! From start to finish, the team was professional, attentive, and detail-oriented. They transformed my vision into reality, and the quality of their work exceeded my expectations. The entire process was smooth, and they kept me informed every step of the way. My new bathroom is stunning, functional, and everything I hoped for. Iconiq Construction is definitely a 5-star company, and I highly recommend them to anyone looking for top-notch renovations!"

"David and Cody from John's Waterproofing went straight to work; they quickly found the problem, showed me the problem, discussed what would have to be done to fix the problem, fixed the problem, then thoroughly cleaned up. Very nice people to work with, from the schedulers through the technicians."

"Very satisfied with the first meeting to go over the work, the honesty in discussing all aspects and giving recommendations, and the detailed estimate. Very satisfied with quality of work as well. The only minor issue was that Brian was planning to finish the work on Friday, but ended up having to run over to Monday. This did not affect me much, he cleaned up before he left for the weekend, and he kept me informed of the delay, so only a minor issue, but just noting the fact."
