Highly recommend! I had some planks that were not able to be walked on our deck. They recommended replacing them all so we would have no other issues. The deck turned out great and after talking to men that did it, realized they do power washing too. Had them do out back porch, walkway, and fire pit. All of which are over twenty years old and came out looking brand new. The technicians were very professional and accommodating.

Just finished having them do my fence and deck for a staining job. The price was fair compared to all my other quotes they did beat out other big companies. The workers were amazing they worked hard and were polite and professional I would recommend this company.

I absolutely loved this company. So professional from start to finish. Their communication with me was the best. Email, calls and texts every step of the way to ensure we were on the same page. It made me feel so at ease. Knew exactly the cost, start date and receipt of payment. Was easy to get in contact with owner. Price was the most reasonable from 3 estimates I got. Workers were polite and worked efficiently. My deck turned out beautiful. Color was exactly what I wanted. Would definitely recommend this company. Roman was great to do business with. Can't say enough positive things.

We used Core Improve and I was extremely happy with their services. They restored, rebuilt and re-stained our deck. They were efficient yet thoughtful in their work. I came home and there were 8 guys working on our deck the first day and everyone was very professional and had good design ideas. They finished the job on time and really worked with us quickly since we were listing our house and wanted to get this project finished quickly. I also thought their communication was excellent. I definitely recommend their services and would not hesitate to use them again.

We just had 2 deck and a front porch cleaned, some boards replaced, sanded and stained and so happy with the end result. Core did an excellent job from start to finish. They came quickly to review the project and provide a quote. The team was very friendly and professional and handled last-minute requests beautifully. I look forward to seeing what other services Core Improve provides that I could take advantage of.
