"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 !"

"I chose this company after comparing three other quotes and initially felt confident signing a contract with them. Unfortunately, my experience was extremely disappointing and frustrating. I hired this company to build an outdoor bar and stamped concrete patio. The bar should of only taken 7-10 days but dragged on for 8 weeks. Workers showed up once a week for only a few hours, and communication was terrible ? I constantly had to text and call for updates and got a 24 hours? notice before they arrived. They even started work before the permits were approved; I had to contact the county to find out. While I?m happy with the finished bar, they never completed the patio that was in our signed contract and stopped responding altogether. I ended up hiring another contractor to do it. The craftsmanship on the bar is fine, but the company?s professionalism, communication, and reliability were awful. I would not recommend this company. "

"Basement Project We absolutely love our new basement! I was very nervous when selecting the contractor for this job. I interviewed three contractors for the job, all seem very decent, but what set Best Home apart was Jeff Segovia. He designed the whole layout of our basement (we love it) and oversaw the entire project from beginning to end. The construction crews were very polite and friendly. Best Home did an excellent job and very flexible with many changes I had and they completed the job on time (took 3 months and exactly 1 week)which was amazing. I am actually hiring them again for additional projects. I highly recommend Best Homes!"

"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!!!!"

" I had an amazing experience with Nationals Home Design! They helped me expand both my kitchen and living room area, and the results exceeded my expectations. Patrick was especially impressive?he showed up every single day to ensure the project was progressing smoothly and efficiently. His dedication and attention to detail really set the tone for the whole team. I?m already planning to finish my basement soon, and I will absolutely be using Nationals Home Design again. I highly recommend them to anyone looking for a reliable, professional, and hands-on renovation company!"

FAQs for addition to existing structure building service projects in Triangle, 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.
