About Us

For your new home, we work directly with our client and their real estate company to select land. We also work with your bank or ours. For your renovation, we work with our clients one-on-one to custom design the renovations of their dreams.


At Andersen Builders, Inc. we recognize that everyone has their own needs and their home should reflect that. That has been Mark's philosophy and that is what makes Andersen Builders, Inc. different from all the rest!

My clients are my business. Therefore, getting to know your needs is paramount.  At Andersen Builders, I satisfy your needs by working one on one with you to accomplish your vision.  Together we will design the home, addition or renovations that best suits your lifestyle, budget and expectations. My specialty is custom designing homes, additions and renovations with computer aided designs, CAD.  Once your computer aided design is completed, you can make changes you can view prior to constructions.  This assures your dream become the reality.


You can count on me, Mark Andersen, General Contractor and my Master Carpenter, Kevin to complete the majority of your construction. We are a hands-on company. Kevin and I do all the framing, siding, trim work, painting, wiring, tile work, cabinet installations and more. We do it all with a few exceptions.  Any work that is not completed by us is completed by trusted, skilled craftsmen I’ve hand-selected and worked with for years.  Kevin and I are always on the job to assure you receive only top quality workmanship every step of the way. From start to finish, we are always on site to assure, The Job Gets Done Right!”  


Additionally, at Andersen Builders we shop each product to assure the best pricing for all products and materials without sacrificing quality.


Customer satisfaction is my number one priority.  I take pride in providing you the best quality work at the best price.  

Weather it is your new home, addition or renovation I honor the trust you place in me.  Not having crews of workers, but instead having Kevin and I doing most of the work and overseeing the rest, to me, translates into better quality control for you!


You can depend on me, the owner Mark Andersen and Andersen Builders, Inc. to build your new home or addition or complete your renovations, and to provide you the same top quality workmanship that has built our reputation for excellence.  “We Do It ALL” and “We Do It Right!”      

From Mark Andersen

Once a CAD design is completed, you can make changes at the Andersen Builders, Inc. office in Effort and instantly see what your home, addition or renovation will look like in 3D.  Have questions about room sizes?  Mark can put a table and chairs or a bed and dresser into your plan so you will know just how big the room is.  You do not have to wonder if your home, addition or remodel will be right, you know it is right from the start!  This is how your dreams will become reality.
