"5 months after they completed the job I'm still compelled to look at my new patio every day. It is simply the best home improvement investment I've ever made. And I'm confident I'll feel this way years from now. Because as good as it looks aesthetically I'm confident that the foundation is solid. I knew a brick paver would look good on the surface, but what earned my confidence in Greenscapes and Bob Wambach was the time we took talking about what was going to go underneath the patio. Talking about the structural integrity of foundations always interests me because I know that's the best way to ensure long lasting enjoyment and best value for the investment. Bob and Lee and the rest of the Greenscapes hardscape team did a fantastic job of building a fantastic patio AND taking care of the customer. They respected our house and our neighbors homes and the neighborhood. Every day they could simply have left all their equipment and made starting the next day even easier for them, but instead they ensured everything was always cleaned up and really limited any disruption for any of us. Some TDS cable laying contractors were working behind my house the week after Greenscapes finished and they left their equipment all over the neighborhood overnight and I had it out with their supervisor when they returned the following day because my expectation now is that anybody can clean up after themselves on a daily basis. Greenscapes has raised the bar and created a new level of expectation for me. I would do business with them again in a heartbeat. My project wasn't even close to being the biggest they've ever done, but it was a HUGE deal for my wife and me and they made me feel like it was a HUGE deal to them. Lastly, Bob and team delivered just what he had designed and showed us electronically. I knew what he designed would transform our backyard, but between the time we agreed to do it and the time the project started I wondered if they'd be able to make that design a reality. They did it!"

"Some of the negative problems a mess was left big chuncks of concrete under my furniture some stuff wasn't covered properly. Something very sentimental to me got broke i got told 'm sorry that happened they were told to becareful due to breakable items. They offered to come back & clean up all the mess that was left & fix some other issues. The two guys who came back for my concerns were very nice & respectful & addressed & fixed the issues. The installation team was very friendly as well but was the ones that left the mess & broke a item of mine I've had for 10 yrs. So very heart broke over that. Now just waiting to see how my basement holds up when it rains heavey or for days at a time."

"The owner Ted lives down the street from me, and after seeing the work he has done to his own house, I stopped and asked for a quote on a concrete patio extension. His quote came in much cheaper than the one we received last year for the same project, and they were able to get it done within days (before my kid's birthday party). On top of this, Ted and his crew went above and beyond by replacing part of the existing sidewalk because he was not happy with how it looked trying to match up to my old shabby slanted walkway. We were extremely pleased with their work and even received several compliments during our party. Boulders Concrete will certainly be my first call on future projects, and I can highly recommend them to anyone in the area."

"We are very pleased with the landscape repairs and sod installation completed by Extreme Lawns. work was completed as promised and for a reasonable price. Brad even went the extra mile to ensure our new sod was monitored and watered while we were away for a short period of time right after installation."

"KJM Plumbing was GREAT! Recommended a person to repair the sink and adjusted the schedule so that they could promptly reconnect the plumbing when the job was done. I am very happy with their service and will use them again in the future."

"Rivera Concrete Paving's $8,500 bid became $11,000. Owner Magdiel Rivera adds charges after you're committed and doesn't follow through after payment. Cost increases: I mentioned roots upfront - he said equipment could handle it, then charged $450. Said grading unnecessary, then created false urgency claiming we HAD to grade before concrete. Later said could grade after. Added $1,800. Crew broke drainage pipes, charged me $250. Couldn't move AC condenser despite my asking during estimate. Payment tactics: Said pay "when satisfied." Then requested half early, then full payment before done. When I said work incomplete, he asked "Don't you trust me?" then broke promises. Broken promises: Walkway cured wrong, no follow-up. $1,800 grading included 3-month landscaping - no communication. Promised debris cleanup, later said not responsible. Damaged 4-month fence, couldn't repair properly, paid $300 after pressure. Dismisses costs at estimate, adds them later. Makes promises, then excuses."
