I recently contracted Cornerstone Construction to remodel my entire home, including a major kitchen, master bathroom, guest bathroom, master bedroom, living-room and fireplace overhaul. All of the walls have been painted and the tile and wood flooring on two stories have been completely redone. My experiences to date with George and Cornerstone Construction have been glowing. George has treated the project as if it was his own home remodel. He has managed the timeline and the finances extremely tightly, always keeping me on point when things needed my input, and has ensured no wasted costs/expenditures. He has been my absolute trusted advisor in all matters and has given me everything straight. He has been so transparent with me that I feel that I understand the construction business myself now! George accompanied me to several vendors helping me select materials, including tile, hardwood, lighting and granite (mainly because I am a very hands on person). At every vendor visit he had deep insight into what would work, and what wouldn't and why. And while he always shared his wisdom and insight with me, I never felt as if I didn't have control over the project and the vision. George has gone out of his way on several occasions to have long conversations with me about the project, brainstorming and sharing ideas. He brings such passion and excitement to every discussion, and it is clear that he is absolutely invested in both the quality of his work product and our shared vision for the project. I am so happy with the experience, the results and the unbeatable price that I am telling all of my closest friends and family about him and his company.

    Ponds are small bodies of water usually tucked deep in the woods or the countryside. They’re a gem to behold but aren’t always easily accessible. The good news is you can design and build one right at your home. And you don’t need a sprawling space to create yours. No matter the size of your yard, there’s a type of pond that’ll fit right in. After all, that’s how outdoor living spaces are supposed to be – natural-looking and spontaneous. Here at Lunaquatic, we design and install ponds of all sizes. Whether you want it feet deep for young children or pets or a little deeper so you can relax and dip your legs in the water, we can build a pond that satisfies your requirements. You won’t have to seek far to get close to nature. You’ll have a piece of it right outside your door, with your customized pond. Contact us today to learn more.
