"In 2022, we decided to add a new kitchen and substantially remodel our mid-1960s Edmonds rambler. After reading many on-line reviews and meeting with several contractors we decided to go with Johnson and Sons.....and we are so very happy that we did. From the very start we were impressed with how open, honest and responsive Vic Johnson was, a trend that continued throughout our project. As you might imagine, a significant remodel and addition to a 60-year old home is likely to bring with it surprises and our remodel was no exception. Despite the many challenges encountered, Johnson and Son and their subcontractors readily overcame them. Among the many lessons we learned during our remodel was the value of quality subcontractors. Vic's relationship with his subs in some cases extend more than a decade and the depth of these relationships was reflected by the quality and timeliness of their work. All in all we feel that the workmanship, attention to detail and care shown by all involved in our remodel was superb. We highly recommend Johnson and Sons to anyone looking to remodel their home."

"This company is built internally the right way. Extremely professional and everything is in house. I repeat...IN HOUSE. If you have ever dealt with a remodeling company that employs outsourced labor, it can be a mis-quote nightmare. Other companies pointed me to handy men for this job not realizing I might need or want more than that in the future. Thank you"

"Decorative beam repairs. Mike and his crew did a fabulous job. Mike came up with a creative idea that ended up looking better than I anticipated. The crew was on time, hardworking, friendly and except for rain delays, pretty much completed the job on schedule. If you have a construction project and you are looking for a company with honesty, integrity and takes pride in the work they do. Look no further and give Exodus a call."

Basement Remodel questions, answered by experts

Anything having to do with the structure of your home, such as raising the ceiling, is usually the most expensive part of finishing a basement. Another project component that could be a surprisingly high expense is adding an exterior entrance. 

The cost of a walkout basement can be anywhere from $5,000 to $35,000.

It is common for a contractor to ask for a down payment before starting a project, especially for jobs that require purchasing materials and equipment or hiring a crew. The deposit amount can range from 10% to 50% of the total job cost. While a request for up to 50% is not unusual, a contractor should not ask for more than that, and you should never pay for a project in full before the work has begun. To protect yourself, always discuss payment terms before starting and have a written contract that outlines the project timeline and expectations. Additionally, be sure to hire reputable contractors and check their licensing and insurance before the project begins.

The average cost of remodeling a basement is $30 to $75 per square foot. If your space is unfinished and looks like it may need more help, use the higher number when calculating your estimated basement remodeling costs. A good rule of thumb is to add an additional 20% to the top of your estimate to cover any “what if” situations.

For most basement remodels, you’ll want to hire a general contractor. This is for a number of reasons, but the main two are that general contractors have dedicated teams they are comfortable with, and hiring one means you only have to deal with one pro. You may also get a better project quote since they can lump all their work and subcontracting into a single quote. 

Building up by adding square footage to the top of your home is often less expensive than adding a basement, but it depends on the specifics of your house, your property, and supply costs. Because building a basement requires excavation, it can be a more expensive option than building up.
