His proposal was right on point with what we expected. The construction team arrived on time, were professional and they efficiently completed the project within the time frame we were quoted. We now have a beautiful, safe and secure pressure-treated wood deck and stairs and we look forward to staining it in early Spring. Here's our "Before and After" photos!

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."

Here at Best Homes, our company is based on the belief that our customers' satisfaction is of the utmost importance. Our team is driven to meet your needs with professionalism, creativity, and efficiency. Established 2005. Owner: Jonathan Perez Office Manager: Paige Marie Campbell Project Manager: Jefry Perez

"Best Homes LLC just finished our basement and we could not be happier! The quality of work is outstanding and the team was always on time, happy to be here and great at communicating. Jefry is a great project manager and always takes your input regarding placement of different aspects and fixtures. It was a lot of fun working through picking out different tiles, flooring, cabinets, colors, etc to make the space how we envisioned it. We even got to choose the placement of extra outlets and things to make the space fit for our use. The price was very reasonable, especially after being quoted nearly double from another contractor. Our basement turned out absolutely gorgeous and now we have a functional, finished space with a full bathroom and wet bar included. The team was incredibly accommodating, gave a generous allowance for tile and flooring, etc. The project was finished with the quoted price and on time, and we will use Best Homes LLC as our go-to for any contracting needs. 10/10!"

"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."

FAQs for addition to existing structure building service projects in Frederick, MD

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
