C.S. Remodeling Inc is new to Angi, we are looking to provide a variety of Skilled Home improvement services. We have been in business since 2001, all of our work has been through personal referral and is 100% residential. I often refer to us as old house carpenters. I've worked on homes from the 1900's to homes built in 2017. Being familiar with the different types of construction techniques lessens the surprise factor and makes modernization or repairs easier. I'm hoping to make the jump to Angi a good one and to continue to provide a positive and comfortable remodeling, repair or home improvement experience. Thanks Craig Stemley

"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."

"We hired Okay Construction for a whole house remodel and it was done amazingly! Bo and Derek were very communicative and responsible for all the work. The job was done on time and on budget! No hidden fees applied or any extra charge on my quote. Quality is also a big part that they did a good job on! Hiring a professional and responsible contractor is hard but if anyone looking for one, these guys are awesome."

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