From Concept To Completion

Buying a new home is one of the most important decisions you will  make. It is essential that you trust the builder that you have chosen and know what to expect. Many builders offer clients the choice of several different plans. You tour the model homes, select, the plan you like most and then select the lot that will fit the plan. Everyone knows that you can’t have everything you want in your new home so a little bit of compromising is necessary. What if things could be different? What if you did not have to compromise?

Your new home

John Boldt Builders constructs custom homes from concept to completion. You don’t have to compromise your dreams for your new home. You do tour the model home but only so that you can see the high quality craftsmanship that will go into your own new home. The model homes are sold because someone comes through the model and decides that it is exactly what they are looking for but most people appreciate the superior quality and the John Boldt Builders difference.

What is the difference in a John Boldt home?

The freedom to choose exactly what you want and to have your custom designed home built on one of the company’s lots or on your own lot. John Boldt Builders have completed over 850 custom homes. When you come to John Boldt Builders you are guaranteed personal attention and Dan Duerrstein is committed to helping you realize your vision of your new home. Through the use of computers and traditional drafting, your ideas and dreams for your new home will take shape on paper becoming the design and layout that uniquely capture what you need and want in a home.

The John Boldt Difference

We build one or two models a year to show our workmanship and the rest are all custom built homes.

What do we mean when we say we are a custom home builder?

First off, we can build virtually any home. Second, sometimes people will bring a plan idea from a magazine, newspaper or just a graph paper with lines on it and we then draw up a plan to their specifications.

BUT DON’T LET THIS OVERWHELM YOU. WE also have many existing plans to choose from. So, if you have only a concept of what you Dream Home will be that’s okay too. We will go through a series of questions to help you determine what your needs are and once those are identified we can find or draw a plan for you!

AGAIN, the MAIN PURPOSE of a model is to show our workmanship, because we are always using the same trades people. Most of them have been with us for at least 20 years and some are second generation.

You also gain peace of mind

You know that John Boldt Builders consistently delivers a superior quality product because they work with the same trades people time after time. Most of the company’s trades people have been with them for at least twenty years. It does not matter whether you have a lot in the city or in the country, the company is equally familiar with wells, cisterns and septic systems as it is with the city requirements.

In addition, if you have a question or want to change something you always deal with Dan Duerrstein. You don’t have to talk to the site supervisor and hope that your builder got the message, there is no confusion over who is in charge or responsible. Dan oversees all the projects individually and provides all the pricing. Individual attention is a way of business not the exception, which is why the majority of the company’s clients were referred by other satisfied clients.
