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."

We are a family owned & locally operated general construction / remodel company with over 60 combined years in the industry. Although we are general contractors and can do everything, we specialize in kitchen and bathroom remodeling. We have found that through proper communication and great listening our customers are more at ease and comfortable from beginning to end. It is our pleasure to provide top service in design assistance, material decisions, planning, demo and project completion. We go out of our way to uniquely tailor our service to each of our customers needs, wants and desires. We realize our customers invite us into their homes to provide the best service possible and we don't stop until we have done our best to help our customers turn their dreams into a reality. Thank you kindly for taking the time to look into Johnson and Sons Construction, LLC. We look forward to the opportunity to serve!

"I reached out to Johnson & Sons and several other contractors to discuss the possibility of opening up and completely remodeling my kitchen and bathrooms, with the addition of a shower to the former half bath off the master suite. After receiving bids and meeting with each contractor, I went with Johnson & Sons due to the transparency and consideration Vic Johnson showed when discussing the project and its challenges, as well as providing a detailed quote. Because this remodel involved the removal of walls, tiling of the kitchen/bathrooms, potential size constraints, and a re-plumbing of the house, It was very important for me that things be done correctly, to code and with permits. Once demo and construction started, things proceeded at a brisk pace with minimal lag between subcontractors, and inspections. Their tile guy, Tony was great to work with and very helpful with making the appropriate detail selections around the showers. We did have a long wait for a cosmetic piece of cabinet siding, which ended up being the final part needed to complete the project. Vic was direct with me about the issue and the delay. Such a minor issue is in my opinion, very small potatoes compared to having quality work done. Ultimately, Johnson & Sons came in slightly under their contract price - a very pleasant and welcome surprise."

Basement Leak Repair questions, answered by experts

In some cases, operating a snake can damage your drain and pipes. This depends on the overall condition of your pipes and how gently you operate the auger. For instance, older galvanized pipes covered in zinc are susceptible to scratches when using a drain snake. Additionally, it’s common for newbies to apply too much force when extending the snake, leading to scratches and related damage. You can also crack the porcelain with an electric auger if you’re snaking a toilet drain. If you’re using a manual snake or auger, the risk is minimal.

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.

In many cases, yes, a damp basement can be bad for your health. Not only can damp air affect your lungs, but it can promote mold growth and pest infestation. Mold spores can be dangerous to breathe in, as can waste particles from insects and rodents attracted to the moisture. Damp, moldy air can also move up into your living area. As such, it’s crucial to fix any basement moisture problems as soon as they crop up.

Common drain issues include slow-running drains, whether in a sink or shower, clogged drains, a bad smell, and water backing up into a sink, shower, or bathtub. Causes range from hair, grease, roots, or toilet paper clogging the drainpipes to flooding outside the home, which prevents sewer lines from draining properly.

The best basement waterproofing method depends on the issue you’re trying to solve. For example, if you have standing water on your basement floor, a floor drain or sump pump might be your best solution. Or, if you have standing water around your foundation, installing a drainage system that protects your basement and foundation might be better.
