"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."

We build our team on "Honesty, Ethics, and Morals". Let us show you the Classic Remodeling NW Inc. difference!

"I am a repeat customer, so I knew the carpenter, Joe, coming in. I started by using their design contractor. I gave her the colors and ideas (beach theme, ceramic wood-look floor tiles), and she pulled the rest together. Invaluable because I can't trust my own taste. They removed a square shower in the corner and a set of shelves next to it, and glassed in that end of the room for a full shower. We put tile down along the whole room, with a recessed shower pan, and a linear drain against the wall. Joe built-in medicine cabinets, and trim all around the room, per my design pictures. The subs included a glass door guy, the plumber, the tiler, painter, and the countertop slab tiler. We also had some work done in our hallway. They removed the single boob light from the middle, and installed two recessed lights on either end, along with putting two switch boxes on either end of the hallway. Joe built a floor to ceiling cabinet in a 13” dead space at the end of the hallway, which included a laundry hamper on tracks, cubbies, and shelves. And then on a whim, I asked to have our old hallway linen cupboard doors replaced to match the new ones. We had two leaks during and after, but one reason I would use them again, is how they handled both times. One was a leak from the plug on the toilet supply. We found it on a Saturday morning, and I ended up waking up our carpenter with my text. He came out and figured it out and fixed it by 1. The other one was after everything was done and cleaned up, and we had paid for everything. The basement bathroom ceiling, fan, and wall below the master was wet one day, and we realized a joint in the pipe from the master toilet to the stack was slowly dripping between the two rooms. I texted Joe again, and he referred me to our GC, who came out with a plumber and fixed it. They had to make a hole in the downstairs drywall, so he has been coming back regularly to put three layers of mud on the new drywall. I was so sure that they would regretfully find that it wasn't their fault and we would have to deal with the cost and bother of finding a plumber and carpenter. Start to finish, it took about four months, but three weeks of that was the initial tile order, and another three for an incorrect tile order."

"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.

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