"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 !"

"We recently had the unfortunate experience of working with Character Companies Inc., and as government civil servants and veterans, we were deeply disappointed. The price of renovating two bathrooms and installing new LVP flooring at $70K (original quote: $84K) seemed excessive, but we hoped that the quality of service would justify the cost. Sadly, that was not the case, and it has cost us the chance to rent out our home while we are deployed to Iraq. From start to finish, the experience was a nightmare. The project management was abysmal, with multiple delays that extended the timeline one month beyond the agreed schedule. It took over two months to do just two bathrooms and replace flooring when the original timeline was four weeks. This company demonstrated a shocking lack of professionalism and accountability throughout the process. The design work was utterly incompetent, failing to conform to the existing plumbing structure in our bathrooms. The contractor disregarded our repeated attempts to bring attention to design flaws and forced the installation of bathroom vanities by performing a â carpentry fixâ that left us with two top drawers sealed shut, one bottom drawer with a cutout, and one fully functional drawer. One month after installation, one vanity separated from the wall and had to be reattached. Our allegations of Character charging us for high-end fixtures and installing cheaper ones were ignored. The final straw was the damage done to our marble floors. Instead of offering a repair or replacement, the contractor covered it with LVP and then charged us at the end of the project for the extra costs of the LVP that they incurred to cover up the damage! This was deceitful and completely unacceptable. The CEOâ s disregard for customer satisfaction and maintaining basic work standards is unforgivable. The only thing he did well was apologize profusely, not caring about fixing any problems. During a phone call, he admitted that our project was a â dumpster fireâ yet didnâ t offer any concessions. We strongly advise anyone considering Character Companies Inc. to stay far away. Their poor project management, substandard design, shoddy craftsmanship, and unprofessional conduct have left us with a costly mess that will take more time and money to fix. Protect yourself and go with an experienced, reputable company."

"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!"

Free Estimates. We understand how stressful and expensive home improvements can be from choosing the right contractor for the job to having your house in disarray for a period of time. If you are updating your home to put on the market, we offer a deferred payment option. We recognize the struggle that sellers face when getting ready to sell their home. Often the main issue is simply not having the finances to make the necessary improvements that will generate a higher sales price. For some it is simply understanding that today's buyers want move in ready homes. ​HEC was started to give sellers and their agents the ability to sell their home quickly and at the highest price possible. There is no secret to selling, UPDATED HOMES SELL FASTER AND HIGHER! Our clients have averaged a 130% Return on Investment when updating their home for sale. We can take care of all of your home remodeling needs from finishing a basement, remodeling your kitchen and bathrooms, to replacing your roof. ​Our approach is simple - we use high quality contractors to make smart updates to your home or listing based on our 20 years of experience in the DC Area Real Estate Market. We do not recommend high end upgrades if they will not generate a good return on your investment. We work with you or your agent to establish an expected price after updates to make an informed decision. The owners of Home Equity Contractors are licensed Realtors in VA, MD, and DC.

"If you want to work with someone condescending, rude, confrontational, unprofessional, and whose contractors workmanship is probably the worst I have ever encountered in my 30 years of working with contractors, THIS IS YOUR GUY. I can ramble on about the false promises, the horrible workmanship, the constant delays, the lack of communication, the rude and confrontational text messages. I guarantee Mr. Shank will in fact respond to this review and try to flip the script and blame it all on me somehow. He talks very poorly about all his customers well at least the ones he doesn't like. Not sure what that is based on although I do have some idea what is based on. But he never made anything explicit, so I can't make accusations that he is a racist. So I am definitely not saying he is a racist because he didn't do anything racist. But if he was a racist it would explain why he didn't give two poops about doing good work for multiple projects I provided him. I also have multiple properties and was hoping to make Mr. Shank a lifelong contractor. In a nutshell, he has done 2 projects for me at 2 properties. One was installing a threshold for a glass enclosed shower stall. His crappy sub contractor (they are not employees) despite him saying they are employees, did not install any grouting on the threshold. Fast forward 1 year, and mold is popping up all around the threshold. Rather than dealing with this individual, I hired another contractor to fix up his mess. Second job, and my second mistake, I hired him for a full scale home renovation for around 50K. That project was an absolute disaster. He took 3 months to do what he promised to me verbally would be a 3 week job. I don't really want to spend 1 hour writing down all the crap he did wrong. I'll try so sum up the highlights. Ripped out old flooring, promised to make new flooring level after installing new concrete by using lasers. New flooring is totally not level and as bumpy as walking on your local trail. The shoe moldings around the flooring look like a child installed them. I had to argue with him to get him to regrout the bathroom which was in his contract in the first place. I can go on and on. For sure if you are someone that Mr. Shank likes and match his criteria of what he likes, whatever that could be I have no idea definitely not race related. He may do a great job for you and that may explain the great reviews. I myself had a horrible experience with Mr. Shank and his group of sub contractors who just plain do terrible work. Ignore my review or take it seriously, frankly this guy will keep getting business cause he's a great salesman. Even has a LinkedIN profile to show how professional he is. Epic scammer and fraud. Stay away."

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