"Jose and his crew are outstanding. Their attention to detail, cleanliness, and respect of our home was incredible. Jose is so easy to work with and he is accessible almost 24/7. I would highly recommend Munoz construction and my family will never use another contractor besides Jose. Bathroom #1 - this bathroom had major issues. The floor was damaged and the shower was leaking. Jose replaced the entire subfloor, shower/tub, title, vanity, and all electrical. This was a major job. Everything was strengthened and given strong structural support. It is now extremely safe and beautiful. Bathroom 2 - the master shower also had a leak and poor tile work from a previous remodel. Jose replaced all the tile and rebuilt the shower pan. He was able to save an expensive shower door from the previous remodel. We also decided to replace the title floor during the remodel and it was not an issue and Jose never questioned our request. LVP Floors - Jose replaced the kitchen, dining room, hallways, and stairs with LVP. Selecting the product was simple and Jose was helpful throughout the entire process. The product was of high quality and is extremely durable. The stairs were replaced with wood and painted to match the LVP. This was done for durability and quality. The stairs match the LVP perfectly. All the walls were also painted. There was some drywall repair throughout the process too. Jose made sure to strengthen all the walls and it looks fantastic. Seriously, we couldn’t be happier with this job. I wish we would have found him years ago so we wouldn’t have had to redo a previously completed renovation done by another company. We highly recommend Jose and Munoz Construction for any and all jobs."

"We are extremely happy with the work done by Thomas Custom Builders (TCB). Overall they did an amazing and outstanding job! They had a contractor on site, on time every day. Brian S. was professional, helpful, patient, hard working and skilled both in managing subcontractors and doing work himself. I trusted him with our home and would work with Brian/TCB again easily. I have already recommended their company to others. TCB renovated a few parts of our house, added electricity to a shed and added an entire master bedroom suite on an additional floor (adding approximately 550 sqft to our house). They finished earlier than expected. Our neighbors couldn't believe how fast the addition was completed and how well done. Any additional costs from the original budget estimate were due to our choice to add more work. I waited to write a review. I wanted to live in the addition for a little while to see how everything holds up. We have had only minor things arise and have been very pleased with the responsiveness of Brian and TCB to come back out and check on things. They came back to add a bracket to a new countertop that moved slightly, they shaved a door that was sticking as the weather changed, they fixed the damage done when carpets were installed by another company, they arranged for a rep from the hot water heater company to come out and fix a noise issue, all done at no additional cost to us. I have worked with contractors before but nothing on this level. It wasn't perfect, there were concerns that came up. I had to learn that this was major construction and with major construction comes mess. Brian and his team addressed our concerns and remedied any issue fairly. With so many negative stories I've heard from people who worked with other companies, I am so very thankful that we had such a good experience and ended up with such an amazing master suite and changes to our home. We love it and we receive many compliments. We chose to work with TCB because they came highly recommended by a neighbor who had similar work done and were very satisfied with their outcome."

"This was our second bathroom remodel by Capstone. The Team did a great job. Their tile work, both in the shower/tub area and on the bathroom floor is fantastic. We had new electrical outlets installed along the vanity and wanted an existing one on the side hall wall removed. Capstone noticed that we did not have an outlet in the hall and suggested moving the existing bathroom outlet down and around to face the hall rather than just not use it. Their thoughtfulness and suggestions set them apart."

"Fantastic! Devin and his team remodeled three of the four bedrooms in my townhouse in Clarendon: the first about four years ago and the other two bathrooms two years ago. He also built me a new closet in the master bedroom. The entire experience was amazing. The work is top quality - years later it still looks perfect and I have not had any problems - and his team is polite, professional, timely and they left my home spotless when they left. And since the work has been completed, Devin has helped me with little issues for free whenever I needed help. He is truly a talented professional and a stellar person. Can’t recommend highly enough!"

"Awesome experience with Total Renovations, LLC. Knowledgeable, responsive, considerate, patient, went above and beyond, informative, a true professional and fair. These are all qualities that were consistently adhered to when working with Russell and his team at Total Renovations, LLC. Having never gone through a home renovation process, we were a little bit skeptical as to which company we wanted to hire to undertake the task of transforming a two-story living room area in our home into a space which converted the upper portion into an additional bedroom. After an extensive search, we found Total Renovations , LLC and its owner, Russell. From day one, which was actually a few months before we hired him and his team, Russell was extremely pleasant to work with. I called and informed him of the task we were wanting to have completed, as well as the fact that we were new to this experience. He was very patient in explaining the entire process from start to finish. Once we had a signed contract between ourselves and Total Renovations, LLC, Russell took it from there. Whether it was obtaining architectural drawing designs, permits from the county, or the construction and clean up of the project, Russell and his team took care of every step along the way. Unlike some other companies that may be dismissive of your project if they feel that it won’t make them enough money, or are dismissive of your task altogether, Russell and his team were a complete joy and relief to work with. They are very punctual, as they show up on time, every time. And I mean EVERY TIME. Additionally, his crew made sure to do an excellent job cleaning up after each day of work. This was truly appreciated as we have a young child and a dog living in the house as it was being remodeled. In this market and with inflation being what it is, we all know that some companies may try to stiff their customers by engaging in price gouging here and there. That was not at all the case with Total Renovations, LLC. The price that they quoted us and signed for was what was adhered to. If anything came up in the project where a particular aspect needed to be changed or corrected based off of the initial assessment, Russell always made sure to reach out to us immediately to explain the reason as to why, as well as obtain permission to proceed. That particular point was extremely reassuring, whereas some other companies may just add extra work to your project without notifying you and then hit you with an inflated bill at the end. At no point in time did Russell ever try to oversell me on any aspect of the project, nor did he brush aside any issue that other companies may feel to be trivial. If we had a question or a concern, Russell had an answer or a solution. Russell and his team were able to take a vision that we had in our heads for our open space, and literally turn it into a reality. Additionally, we were able to add in some recessed lighting and ceiling fans along the way. The attention to detail that his crew invested into our project was above and beyond even our own expectations. It truly feels like we are living in a new house. If you have a task or project that you’re thinking about having done with your home, we HIGHLY recommend that you chose to hire Russell and his team with Total Renovations, LLC. We guarantee that you will not be disappointed. We also guarantee that you will love the end result."

"From our first visit to the Waterstone office to the final walkthrough when the project was completed, our experience with Waterstone was fantastic. Jeff Thompson and Deanna Llewellyn designed the new kitchen, taking our input and making a plan that was better than we hoped. The entire renovation process was done professionally, with respect to the fact that we were living in the house at the time. Javier led the crew, and every day the site was cleaned up and Javier took the time to explain the work they'd done that day and what they would do next. The project came in at budget, it was done on time, and the work was top notch. We're very happy with the outcome, and in fact, we've talked to Jeff about the master bath. I give this group my highest recommendation."

"Excellent diagnosis of the work needed. Complete review of external meter and cable rigging needs, upgrade to new panel inside the house and corresponding grounding under the house (crawl space). Very reasonable pricing as well. I’ve hired D&G Remodeling for the work. The Lord is good! Thank you Angi!"

"I have used Navid's Construction for several projects at two homes we've owned. The first job required replacing front porch posts on a vintage, 1928 Sears Craftsman Bungalow. We were selling the home and needed to replace a rotting wooden structural porch post having architectural design features that I was adamant about replicating exactly as the original construction. Navid was able to completely reconstruct both posts with their added design features and do that work FLAWLESSLY!! I was incredibly pleased with the final results that he was able to accomplish within one day between him and his crew. This was all done, btw, within one week of closing with our buyer in advance of the sale of the home! A bit harrowing for me, but no problem for Navid! He also tackled reinforcing a joist and taking care of some termite damage. I engaged him again for another home of ours to reinforce a termite damaged joist and repair a 2nd floor drain. Success on all fronts. Total pro; use NAVID!!"

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