"Vadim and his crew did a great job on our kitchen remodel. They finished everything on time and stuck to the budget, which was super important to us. They also helped us pick out the cabinets, countertops, and tile as we had no idea where to start, and their advice made the process easier. The kitchen turned out exactly how we wanted it, and we are so happy with the quality of the work."

At Classic Remodeling NW. Inc. our mission is to build lifelong family relationships with our clients, co-workers and community neighborhoods through the remodeling process. Our guiding principles are those of commitment, honesty and personal accountability through a high level of communication and respect for one another. We can build or remodel any part of your house to make your dreams come true! Communication is a tool we use every day to make sure we know what you want. We keep your home neat and clean the entire time we are working and make sure that your satisfied. With Classic Remodeling NW Inc., you are not just a customer, you are family. Our team gets to know you personally so we can make sure your dream will come to life and you will be more than satisfied with the results, and the cost! 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."

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

Yes, hidden rooms are legal, as long as they meet all local building regulations. If you sell your house, most states require homeowners to disclose full houseplans, which would include any hidden rooms.

If your secret room is a safe room, it should contain a means of communication aside from a cell phone, such as a shortwave radio. You should also have plenty of drinking water, a portable generator, emergency food supplies, blankets, pillows, flashlights, batteries and a first aid kit.

Any time you update your home’s square footage, you increase its value, but a secret room is a niche feature that doesn't rank high on every buyer’s list of must-haves. Investing your money in remodeling more common living areas like bedrooms, bathrooms, or kitchens will have a higher ROI than adding a secret room. Many secret rooms can act as entertainment spaces (think a game room or wine cellar) or quiet spaces (a library or study), so when building your secret room you may want to consider its versatility for when you’re ready to sell.
