"Kevin worked with us on our home remodeling project in 2023/24. We had a dated 1979 property that needed totally redesigning to eliminate some pretty awful existing features. Kevin came up with a number of possible solutions for the design. We finally settled on a scheme that we were happy with. Kevin was very tolerant when we then changed our minds requiring him to redo some of the drawings. Kevin has also been available to offer help and advice during the construction process."

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."

"We had an outstanding experience with Sean and Bzr team. From the initial call with Gaby to the finished product. I highly and strongly recommend BZR. We first started with a bathroom addition and ended up with an ADU project which turned out great adding a kitchen and 3/4 bath. It did take time and many changes, I want to thank Sean for his patience. I would absolutely in a blink work with them again. I will upload photos when wife has finished furnishing."

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