"My husband and I have built multiple homes over the years for our growing family. Andy Gruhn was by far the most high quality excellent homebuilder on every level. I truly cannot rave enough or even express my gratitude for the amazing Home They built us!!!! From start to finish, they went way above and beyond, they were quality in details that as a new homebuilder, you donâ t think of until, after the fact, sometimes years, after the fact, I still marvel at the things they thought of for us, that we didnâ t even ask for, that they provided for us to be sure our large family of small children would be taken care of and comfortable for years to come. at the time we were on a very tight budget and they were more than generous. I am beyond grateful to have worked with him and for the quality home they built for our family. They couldâ ve cut corners to save money and make a better profit but instead they just gave us a better home Now that Iâ ve worked with a new builder, Iâ m even more surprised at everything that was included in our home. Heâ s just a standup good community building person that stands by his words and means what he says. When we move back to Washington state Iâ m hoping to build with him again hands-down, I truly canâ t express my gratitude. Andy doesnâ t just build homes he builds communities."

"I wanted a sturdy shed built on my poured concrete slab. I knew how large I wanted it, but after that, I needed help. Nate worked with me to design, build and finish my 12x16 shed from start to finish. The process was efficient, and the shed is beautiful. Honestly, what I call a shed, would probably classify as a garage, had we installed a garage door, but that was not what I needed at the time. While working with Nate, I quickly recognized he could be trusted to find a solution to any problem. Next he helped me plan and built a matching railing for my home’s staircase, after I had previously removed an old rotting one. Again, this process was quick easy and friendly. Sadly I moved away from the area, but if I ever return, I will always reach out to Nate first for my building and remodeling needs."

"Had them rip out the fireplace that was installed poorly in 1990. A bit costly, but I doubt a single handyman could have done it in a timely fashion. Done in 3 days start to finish. I was expecting some water damage, but it was much worse. Getting a exact price for the work out of them beforehand was impossible. Ultimately it cost $2500 extra do to having to replace more sections of the roof and support beans. They didn't pull a fast one, the wood crumbled when touched. Labor isn't cheap. Would hire them again because the work is solid. "

FAQs for addition to existing structure building service projects in Olympia, WA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
