The sales and design team were very responsive and walked me through all of the material options. The design team captured perfectly what I wanted. This project was a tear down of a thirty five year old deck and a complete rebuild. They have a logistics person who communicated regularly with me the scheduling and status of the project. The crew that built the deck were true craftsmen. It became obvious to me after day one they all were very concerned about the detail and quality of their work.Posted on Google chris geezyTrustindex verifies that the original source of the review is Google.

My experience with Cedarbrook Outdoor Design/Build was exceptional. I had a ramp built leading from my front porch to the garage and driveway. The original builder I hired skipped town before I could get the ramp to pass the Frederick County building code inspection. For several weeks I looked for a reputable builder to correct the ramp’s deficiencies but there was no one interested in doing the work. I finally ran across Cedar Brook in the Best Pick Reports for Frederick County periodical. I described my situation to the Administrative Assistant, and she checked with the owner. Within two days the owner appeared at my home to look over the ramp and provide me with a detailed estimate of what it would take to pass inspection. Due to the small project size, the company was flexible enough to start the project within days for me to meet a critical deadline with the county. On site, the construction crew wasted no time getting to work and getting the project complete. The crew kept me informed of ongoing progress and any issues that arose, while company management updated me on upcoming inspections with the county. Within a week and a half all work was complete, and all inspections passed by county inspectors. The project came in on schedule, within budget, and fully compliant. What more could I ask for? From the owner to the construction team and office staff, all employees were professional, courteous, and extremely knowledgeable in their duties. I highly recommend Cedarbrook Outdoor Design/Build for your future construction needs.Posted on Google Jennifer ListTrustindex verifies that the original source of the review is Google. My husband and I had plans for a deck renovation and a screened porch addition. After meeting with Mike, our plans grew into a 3-season room. As with any big project, it took some time to build, but we are thrilled with the outcome. We have an incredible addition to our property and to our lives. Mike has put together a great team. We dreaded having strangers on our property for such a long stretch of time, but overall, they were just great people and actually nice to have around. They use top notch products for a beautiful, quality finish. His team did everything for us from creating a gorgeous design to building an addition that fit so perfectly with our home that it looks like it was part of the original build. We will be forever grateful that we chose Cedarbrook.Posted on Google Paula CanovaTrustindex verifies that the original source of the review is Google. Cedarbrook Outdoor Design built our deck and porch! The quality is top notch and their crew excellent! We have waited nine years for our deck and porch and it was well worth the wait. I highly recommend Cedarbrook Outdoor Design!!! You won't be disappointed!!Posted on Google Steven MartinTrustindex verifies that the original source of the review is Google. We had a great experience with Cedarbrook who came out and fixed some rotten stairs to our deck. The were timely in their estimate process as well as very timely in getting the repairs done. The stairs are solid and look awesome. Also during the repair process I asked for a change which the quickly accommodated for which they had to scramble staff to get and delivery extra supplies. Additionally, their home office staff were a pleasure to work with and went out of their way to be helpful in helping process some warranty claims for some of the decking boards that have become bleached out over time. I highly recommend Cedarbrook to anyone looking to design and build a deck!Posted on Google Kim BartmanTrustindex verifies that the original source of the review is Google.
