Our Services

We design and install custom porch enclosure systems that transform open and covered outdoor spaces into protected, functional living areas.

Porch Enclosure Installation

Our team covers every phase from design and permitting through framing, panel installation, and finishing. Every system converts your existing structure into a comfortable, weather-protected living area.

Open Porch Construction

We design and build open porches that provide a welcoming outdoor gathering space suited to any home's exterior. Every project is constructed with the same structural precision and material quality we bring to all enclosed structures.

Porch Footing

Every porch structure begins with a properly engineered foundation selected to suit your site's conditions. We work with helical piers, diamond piers, and traditional concrete footings for a safe, stable, code-compliant base.

Porch Types We Offer

Porch Enclosure Systems and Screened In Porches

Porch enclosure systems use screen windows and panel solutions to convert existing structures into protected, ventilated living areas. Screened in porches enclose outdoor spaces with framed screen panels that block insects while preserving natural airflow and views.

Sunrooms and 4 Season Rooms

Sunrooms bring natural light and outdoor views into a glass-enclosed interior space suited to relaxing and entertaining. Our 4 season rooms provide full insulation and climate control for comfortable year-round use.

3 Season Rooms and Covered Porches

Our 3 season rooms deliver an enclosed outdoor experience for spring, summer, and fall using screened or windowed walls. Covered porches provide overhead protection from rain and sun while maintaining an open-air connection to the outdoors.

Open Porch

An open porch delivers a traditional welcoming outdoor space that enhances curb appeal and adds a comfortable gathering area to any property. It provides a relaxed outdoor living experience with no enclosure required.

 Trustindex verifies that the original source of the review is Google. We couldn’t be happier with the new deck Cedarbrook built for us. They were creative and thoughtful about the design, stayed on schedule, and were incredibly responsive throughout the entire process. Most importantly, the quality of the finished deck is outstanding. We’ve already gotten a lot of  compliments from friends and neighbors.

The crew was professional and considerate from start to finish. They kept the site clean, kept noise to a minimum, and were always willing to move equipment or materials when they were blocking our garage. They also quickly took care of the few small things we noticed during the final walkthrough.

We had a great experience with Cedarbrook, strongly recommend them, and would happily work with them again.

 Trustindex verifies that the original source of the review is Google. Cedarbrook completely transformed our backyard patio and deck.  Our project was in many ways complex, including the need to re-engineer and remove deck footers beams for more space between, while not tearing down the entire deck as the deck boards, railing, etc were all still in great shape.  We were installing new hardscaping features such as pool, wood fireplace, gas fireplace and bar and counter area on the patio.  Mike (owner) met with us and instilled confidence they could get the job done.  From the start, we had a great relationship built on trust, communication and transparency.  Whether working with Tina as PM, Wayne as foreman, Kristen for invoicing/billing, Mike as owner, or any of the numerous team members we had at our home, all were courteous, professional, and focused on completing a job where every detail mattered.  A project of this magnitude will never go perfectly and when issues would arrive, Tina, Wayne or Mike would let us know and work collaboratively with us to find solutions.  The pictures speak for themselves.  If I had another backyard to transform, I would call Cedarbrook again, without hesitation.

 Trustindex verifies that the original source of the review is Google. We purchased a house in Olney last year, and knew when we purchased it that the deck needed some issues addressed.  We met with several contractors and received quotes for the work.  After meeting with Mike and Sam from Cedarbrook, we knew from their professionalism and years in the industry that we wanted to hire them to do the work.   They took the time to meet with us and answer all of our questions, to fully understand our vision for the new deck, and also to address our concerns about replacing the ledger board, as our basement is fully finished.   Their solution resulted in an extremely sturdy frame for our new deck that wouldn't require any holes in the finished basement drywall.   The entire process from demolition through final inspection was extremely easy for us as homeowners.   We are so glad that we decided to go with Cedarbrook for our project.  We could not be happier with the process, communication with the Cedarbrook team, and final results.  We would definitely recommend Cedarbrook for anyone considering having a new deck built on their home.

 Trustindex verifies that the original source of the review is Google. Cedarbrook truly delivered! From a complete deck rebuild to fixing a shifting second-story porch, they handled everything with professionalism and expertise.

Lenny was awesome and worked with my timeline while I was in the middle of refinancing to afford the repairs. He even helped with some appraisal repairs so the loan would go through.

The finished deck looks great; they used quality materials, and most importantly, it is sturdy, safe, and we love it!

I'm 100% choosing them for a future project I have planned. 💯🏡🛠️

 Trustindex verifies that the original source of the review is Google. Cedarbrooke gets five stars in every phase of our project. 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.

 Trustindex 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.
