What to Expect


Design Consultation

Our first interaction will be a discussion of your project, what you want to have done, and the budget you have set…
aside for that project. Since a formal estimate can often take over a week to provide, we try to give our customers a ballpark quote during the first meeting. This allows you to begin to marry your dream with your budget and start talking about the practicalities of the project from Day 1.

Design Delivery

After our initial meeting, we complete the design and estimating process, and deliver our written estimate and floor plan design based…
on your feedback. This includes individual counts of all materials and labor for price transparency. Our goal is to help you look at everything every step of the way until the plans for your new home are complete. And now the exciting part, the work can begin!

Home Construction

The home plans are carried out by our team of professionals with each detail of the floor plan and design…
delivered, ensuring the highest quality product is delivered to you. We stay in communication throughout the build process: so you always know how the job is progressing, if something unexpected comes up, or to answer your questions as the job progresses. Building a house is a dynamic process with many big and small decisions along the way impacting the quality of your build. Our customers enjoy being able to reach their contractor throughout the home building process, to discuss the merits of the different options, and be close to the project manager they have onsite. By the end of the construction process, we have delivered a home that fits you and your specific style and have built a strong relationship that will continue to be there for any more home dreams you come up with!

Post Construction

Once the construction process is finished, we do a final walkthrough of the home to ensure customer..
satisfaction is high. Even after our final walkthrough many customers stay in contact with us. We are proud of our many relationships across Charleston and the surrounding areas. Unlike many builders in the area, we stand firmly by the quality of our build. We offer not just a 1-year workmanship warranty but a 5-year warranty – Charleston’s strongest guarantee. We believe in never skimping on quality which is why we have no issue offering the longest guarantee in the county.

What Makes Oak Angel Builders Different From Other Home Addition COntractors?

Choosing between different home additions contractors for your project can be a difficult process. Here are what our customers say make us stand apart.


Transparency and honesty in our communication is very important to us. We work hard to get our estimates accurate and are upfront about the budget and expectations that will come with it. Each of our estimates also includes breakdowns of the materials and labor so that you know…

what you are paying for and how we arrived at the price.

We are not “yes men”. If there is something about the project we question, we will go over it with you. If something comes up during the project, we pause work and let you know. We never compromise on the quality of our work and that includes our customer service. Honesty and transparency are our hallmarks and 90% of our customers say they choose us because of this.


One of the unique things we offer is the ability to turn lumber cleared from your property into custom wood features for your home. This gives a sustainable way for our clients to have a truly unique item in their home. We have experience creating custom shelves, window trim, tables, countertops, and more!
