C-n-J Construction LLC was established in 2001 by Charles Johnston. With hundreds of satisfied customers throughout Blair, WI and the Coulee Region, we continue to grow while staying true to our founding principle: to not only complete projects on time and on budget, but to meet or exceed our customers’ highest expectations.
Charles has over 45 years of hands-on experience in construction, specializing in custom decks, four-season porches, additions, siding, windows, doors, roofing, and full interior remodeling.
"Here at C-n-J Construction, every customer is treated equally regardless of the size of the job. Whether you are spending hundreds of dollars or tens of thousands of dollars, you the customer are the most important person to our success."
Traditionally, most of our business comes through referrals. That’s because we treat every home like our own.
From repairing a storm-damaged window casing or rebuilding a small deck railing to framing a full two-story addition, we approach every project with the exact same commitment to perfection.
You never have to deal with middlemen or salespeople who disappear after the contract is signed. Charles Johnston is actively on-site, supervising craftsmanship and communicating directly with you.
Hiring a contractor is a major investment. We respect your schedule and budget by providing clear written estimates upfront and keeping projects moving efficiently toward completion.
Our dedicated crew members are proud to work alongside Charles. We treat every job site with cleanliness, respect for your home, and an uncompromising work ethic.
