"I recently chose Harford Custom Homes to renovate the master bathroom in my 1900s home. With the complexity of the age of the home, I believed the dreams I had would be unachievable. Joe and Kyle made it happen! Not only do they have incredible attention to detail, bringing my dreams to a reality, they are always available. If I had a question or concern regarding any step of my project, they were a call or text away. If I felt like something wasnâ t exactly the way I dreamed, they fixed it - no questions asked. They additionally worked timely to get my project done in just a few weeks! I cannot express how pleased I am with Harford Custom Homes and would recommend them to anyone looking to get a custom job done. No matter how big or small, old or new. Thank you Joe and Kyle!"

"When I started down the path of remodeling my 2 outdated bathrooms, I had no idea what to expect. My two main criteria were fair price and good workmanship. Abode Construction delivered this and more! Scott provides top notch work, respectful and capable crew, quality customer care, and advice, all for a competitive price. His team, from the estimate to changes for the project through completion of the bathrooms, make the client feel valued. Did everything go as planned? Absolutely not. Some events were unavoidable (e.g. supply delays) but some could have been avoided. However, Scott made sure that we were whole at the end of the day and made good on his 100% guaranteed satisfaction. I now have two updated, modern bathrooms that we all LOVE! I will be using Abode Construction for future projects and highly recommend them to others."

We pride our company on reliability, great communication, integrity, and quality work. We strongly believe in giving our absolute best in all of our projects no matter how big or small. We are experts in our trade and will always keep you educated on your particular task or project. We look forward to earning your business!

"All the people at Elevate Design and Build were amazing and a pleasure to work with. We doubled the size of our house including tripling the size of the kitchen, knocking out walls to create an open floor plan and added a three car garage with home office over the garage. They even recommended modifications to our original blueprints which were excellent. All their workers friendly and did a first class job. Went totally above and beyond our expectations. One year later we have not had one single problem with any of the work. Total integrity. If any issue came up, the company absorbed the cost - not the customer. Everything they did was done perfectly. We didn't have a single issue or complaint during the entire process. I give them my highest personal recommendation. I would never use anyone else."
