"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."

"Justin Gibbons owner of Carpenters Unlimited LLC brought an illegal employee to work on our project alone (claims no employees with WA L&I). When mistakes were made, Justin GIbbons blamed the employee, attempted to fix the errors, but did not succeed in fixing the errors. Based on the work Justin Gibbons and his company Carpenters Unlimited LLC provided, we would not recommend Justin Gibbons and his company Carpenters Unlimited LLC to family or friends or anyone else. The work Justin Gibbons and his company Carpenters Unlimited LLC provided was subpar, completed late, required many follow ups from us to get fixed, and resulted in damages. We are pursing a Small Claims case against Justin Gibbons. See photos for evidence."

FAQs for addition to existing structure building service projects in Spanaway, 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.
