From shape, color scheme, to material and electrical. When demo day came the crew worked efficiently and kept my property clean. Carefully not leaving behind nails or debris that my children could accidentally step on. The construction crew came shortly after. As a single mom feeling safe is a high priority. Every single member of the team treated my home and the kids and I so respectfully. The kids would get off of school and would come check on progress. The guys were always friendly. Finally the end result is result is so stunning. I may be slightly biased but I feel like Diamond Decks constructed the prettiest deck in my neighborhood. Thank you so much for adding so much beauty and value to my home.Posted on GoogleTrustindex verifies that the original source of the review is Google. They did an awesome job.

I contacted Diamond Decks to screen in my back patio but expanded the project financing and asked for ideas based on the proposed budget. The completed work FAR EXCEEDED my expectations. I had an idea of what I wanted and they made it come to life. Only negative is I wish I had given them a bigger budget because now I want to spend all my time on my back patio.Posted on GoogleTrustindex verifies that the original source of the review is Google. Joseph from Diamond Decks just completed repairs on our poly textured front porch. Due to weather and lots of foot traffic, it needed some attention. We couldn’t be more pleased with his work. The original coating was applied by Diamond Decks in 2019 and is one of the best investments we have made in the home. The porch looks fantastic.Posted on GoogleTrustindex verifies that the original source of the review is Google. Today I am enjoying my beautiful patio arrangement.

Diamond Decks did an amazing job of removing my existing arbor which was above my existing deck and replaced it with their bronze Renaissance aluminum arbor. Joshua, Brent, Alex and his team (Felix and Jesse) were extremely professional, focused and exceeded my expectations. I will not hesitate to recommend Diamond Decks to friends and family!
