The Process of Working With Us


Short Interview

Please reach out to us by filling out the form on our website and tell us about your project. We will review your project to make sure it’s a good fit for both of us. After that, we will call you back to schedule an appointment where we will talk about your project in more details.


Complimentary Onsite Meeting

These meetings typically last between one to one and a half hours, depending on the size of your project. Our appointments are scheduled during regular business hours Monday-Saturday 7:30am – 5:00pm.


What Happens at the Complimentary Meeting?

We will start the discussion with why you want to remodel, your expectations for the project as well as review your vision for the spaces you want remodeled. Then we will talk about schedule availability and completion requirements for both you and us.

After that, we will talk about the investment you are comfortable putting into your home (It’s a good idea to talk about the budget before our meeting) since the most people don’t know what remodeling costs. It’s clear to us that everyone has a budget number that they are willing to spend. Being honest about your budget allows us to assist you in staying within it.

We will gladly answer any questions you may have about the project or the processes of our company. We’ll examine a ballpark figure determined from our early conversation. This broad brush number is intended to determine whether this is the direction you want to follow. When you are ready to go, we will advance to the next stage.

After completing all of the steps mentioned above, we can move on to getting the permissions and construction phases of the project.

Bathroom Remodeling

Even the smallest bathroom upgrade can provide a lot of benefits. Not only can it be transformed into a place of peace and relaxation, but a well-designed bathroom remodel will ensure that all of your fixtures and plumbing operate properly and efficiently. Remodel will also enhance the functionality of your bathroom and will increase the value of your home.

From beginning to end, we work with you to guarantee punctuality and satisfaction. We will discuss your specific needs and quickly begin updating your bathroom. Bildco Inc. is always glad to assist you in transforming your property through a customized renovation process.

Kitchen Remodeling

One of the most common home improvement projects is kitchen remodeling. After all, the kitchen is the centerpiece of life in the modern home. If your kitchen is out of date or does not suit your functional needs, it’s reasonable that renovating is high on your wish list. A kitchen is much more than the space in which we make food. Kitchens have a tendency of being the heart of the home

It is a gathering spot for long talks over a cup of coffee, a room for homework or family game night. Enhancing your kitchen’s appearance, comfort, convenience, and usable space makes each moment spent in your kitchen much more pleasant. When it’s time to upgrade your kitchen space, you can rely on Bildco Inc to get the job done.

Home Additions and Expansions

Have you outgrown your current home and need a bigger one? Then you should think about expanding your current home with a home addition. Properly constructed home additions enable you to maximize and expand the space on your property in order to meet the expanding needs of your family.
Not only are you increasing the size of your home, but you are also increasing its worth. At Bildco Inc. we work closely with clients to identify the most cost-effective and realistic approach to achieving their dream.

Adding space to your home is a big task, and our project management team emphasizes teamwork and open communication throughout the entire construction process. If you have decided that the addition is the perfect choice for you and your family, we will go above and beyond to achieve your complete satisfaction with the finished project.
