"Eco Power Works did a great job on my kitchen and bathroom renovation ! Daryl and John were very patient listening to my ideas. They brought in an architect who was reasonably priced and made suggestions to overall designs which I am so glad they did ! The project from Start to finish was on schedule which O was pleasantly surprised - these guys kept their words and their workers were always on time respectful of my property and time. I like that they always checked with me when they took major steps to double check that everyone was on the same page - they communicated every step of the way and were very careful to to do the job right. I really love the beautiful cabinets and marble countertops which were my dreams. I am so glad I hired these guys - they really did a great job overall - will definitely recommend them to my friends and neighbors !"

"Victor and his crew were extremely professional and very easy to work with. Victor was always readily available to answer any questions/concerns we had and was on site most of the time. The same crew was there from the beginning and they were very nice and courteous. They seemed to really care about the small details and before I pointed anything out, Victor would point it out and tell me they would take care of it. This is the 3rd project we have done on our house (using 3 different contractors) and by far Skylight Builders has been the best contractor we worked with. We are already planning on working with him again for our back deck. I wish I had used him previously."

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!"

"Seddik and his crew did great work on my house addition. The constant communication and attention to detail made the evolution stress-free. We were able to move back in a week earlier than initially quoted and the final cost was within a few percent of the estimate, mostly due to additional touches we added on during the build. He was also extremely responsive to any issues that popped up after the job was finished to make sure everything turned out exactly like our family wanted.

"If I could give zero stars I would! We had the most HORRIBLE experience with Christan/Nighthawk!!! We had a 3 phase home addition that was to be done in 6 months. It took 11 months and he only made it thru phase 2. He took our money then proceeded to only show up once a week for most of the project!! He left our roof off - exposing our home to extensive damage that he ignored - for 3 MONTHS!!!! He claimed we were a priority project to him and yet never showed up. And to add insult to injury the work he did was AWFUL! Framing was left exposed to the elements so long it grew mold (that we had to treat on our own dime) and the inside framing was so wrong that we had to rip it down and fix on our own. Beware of a sheep in wolfs clothing. Christian talks a good game and you'll believe he is a good guy/business man but he did us sooooo wrong!!! All I can say is do not make the same mistake we did - go with someone else!!!!"

FAQs for addition to existing structure building service projects in Great Falls, VA

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.
