Quality is our Goal! We are a locally owned and operated company that values honesty and integrity, and stands behind our work. Our services are customized to the individual project, paying close attention to the details of each project that we're involved with. We look forward to building long-term relationships with our clients and guarantee your satisfaction!

"I hired Adam to tile the shower in a bathroom addition. It was four walls, ceiling and a niche for bottles for shampoo & conditioner. The tiles were not small (12x24). He did a fantastic job, and also installed a feature strip with 12" glass tiles. When finished, the place was spotless (all trash in a contractors grade garbage bag that I had to dispose of). His price was significantly lower than two other quotes, but I picked him because of his bold expression of his faith (on his business card and the shirt he had on when he came over to look at the job), and the other reviews on Angi. I highly recommend Adam. You will be very happy with the results."

"Excellent communication from beginning to post installation made them super easy to work with Installers were on time, did a great job, were patient and helpful when we needed to make a last minute change in design. On top of all that they actually cleaned up before they left rather than leaving a mess like so many contractors do. They do a lot more than quartz countertop installation, and I would definitely go back to them for any future projects."

"Jessie was a true professional. He arrived on time, got us our quote within the day. Followed up to see if we had questions in a timely manner. Jessie had all his samples with him and a catalog to pick our sinks from. No pressure to sign a contract ever. He was understanding we needed time to decide. Treated my wife with respect (other sales people directed questions to me and not her, they made her feel invisible). Jessie’s prices were fair and reasonable, so we decided to go with him. The installation took a day and everything was as promised. He was careful and respectful of our space and time. Thank you Jessie for the excellent job and the beautiful countertops. He also made us two cutting boards at no extra charge."

With over fifteen years of experience in various interior renovations, I take pride in producing clean, strong, appealing finished work that is always level and square. Clients appreciate that I am on the job every day until it is finished, as I only do one job at a time. My estimates are firm, with no price increases unless additional work is requested. My clients have all been very pleased and I'm happy to give you referrals. Let them tell you how I do. "A passion for precision"--that's my motto.

"Dylan is a gem! He responded promptly to my request for a quote, followed through with consistent communication, and was a pleasure to work with. He repaired a granite kitchen countertop and did so in the cleanest way possible by keeping his vacuum host taped to the location where he was grinding down the edges of our counter. He also showed up on time, went and purchased an additional item to shine the new edge of our countertop, and cleaned up after himself. I will definitely use him again!"

"GreenHouse did a fantastic job on our new deck and porch from beginning to end. Juan was instrumental in developing the overall design concept, as well as brainstorming ideas for how to implement some of the custom details that we wanted (including a drink table for our hot tub!). He offered various design schemes for the deck boards, railing and stairs, as well, presenting options for upgraded looks and function while never pushing for pricier items (he even steered us away from the highest end composite panels because he didn't believe that we would benefit enough from it). Ricky and the construction team were friendly, always on time and created an extremely sturdy and attractive deck that was just as cool - or better - than Juan described during the design. Overall, GreenHouse delivered on their promises, finishing in even less time than they estimated and at the agreed budget price with no change orders or markups along the way. I highly recommend them and would happily hire them again!"

Installing countertops by yourself is a challenging task. Professional installation is always best, regardless of surface type or budget.

Yes. It is possible to just lift the countertop and replace it without damaging your existing cabinets.

It is time to replace your countertops when they have cracked, stained or burned. You can also replace them anytime you want to create a fresh look or when you are updating our kitchen appliances and need to redesign the counter space.
