All Renovations was started by a local graduate of George Washington University. We are fully licensed in all trade work including building, electrical and plumbing . We have always put our customers first in delivering what we promise without any gimmicks. The reputation of our company is proven through our satisfactory track record including winning the highly coveted Angie’s List Super Service Award and being selected as a Best Pick Report contractor on numerous occasions. The staff at our company values your time with prompt on site visits, quick turnaround in providing cost estimates, and a responsive attitude until job completion. We can assure you that our pricing and written warranty provides value in your investment when compared with other professionally licensed contractors. Due to our staffing requirements we are only able to take on jobs $10k or higher.
"I am giving All Renovations 5 stars for the basement renovation in large part because of Adrian’s excellent craftsmanship and attention to detail. Our job was pretty extensive. It included moving support columns, demo and rebuild exterior stairway, adding a full bath, extending the finished/framed portion of the basement, moving the circuit-breaker panel, and re-doing our half-bath. The job took 6 months, which was about twice as long as we expected. Omar was always very responsive and provided good feedback. Adrian is very good at explaining things and soliciting your input when options/alternatives exist. He definitely does not take short-cuts if quality would suffer. He is also very considerate/careful inside your home and cleans-up after himself. Our $102k project ballooned to $125k, mostly due to nice to have add-ons and unforeseen issues. But there were several items I feel should have been caught at the contract onset. E.g. the need for a floor drain ($900), considering that we were getting rid of the utility sink basin. There was also an extra $4k to replace the drywall in the half bath since the existing paint was too textured (sponge) to paint over. But we were very pleased with the outcome and would definitely recommend All Renovations."

Whether you want to remodel your existing home or build a brand new one, Thomas Custom Builders can help. Our 70+ years of combined experience as Northern Virginia general contractors and our commitment to quality ensures your custom construction or design-build project will be a success. Be it a master suite, custom kitchen or home addition, we dig deep to learn what’s making you spend your time and resources on this particular project. We honestly discuss the costs associated with your goals, then we deliver what we do best: excellence in custom remodeling. The only thing that counts is finishing your job exactly the way you want it. No compromise.
"In short, things went GREAT, and I can whole-heartedly recommend Thomas Custom Builders (TCB), which is a "design-build" firm. Here's how things went: Firstly, expect that they have a backlog, and it may take a while to get to your project - probably because their reputation proceeds them. It took nearly 9 months between when we started with them on scoping our our project to when we broke ground, however we ended up with a design that worked. Through that phase, we worked with TCB on what goals we wanted to achieve, and what our budget was, and they designed to achieve as much of our goals within our budget. During construction, TCB promised to have a foreman who spoke fluent English on-site every day, and they delivered on that. This stood in pretty stark contrast with some of my previous contracting experiences, where the project could languish without seeing anyone come to the site. With TCB, the project always moved forward - sometimes it moved rapidly, with multiple trades on-site - sometimes it moved moderately, with the foreman and a couple helpers - and sometimes it was just the foreman handling things himself - but it always moved. TCB also is the kind of company that won't nickle and dime you. If something small is missed in the project scope that is needed to really complete the project, they'll do it. Don't expect them to shell out thousands of dollars in that respect - that would be a change order (which I had one) - but at the end of the day, I very much got the impression that they really took pride in their work and wanted me to be happy with the end result, which I am. TCB estimated the job would take between 3 to 4.5 months, and they completed in 4 months. I had one change order to connect my concrete/flagstone walkway to my stairs, which we had missed in the scope and was too big of a cost for TCB to absorb ($2.5k), however that was the only overage, so all in all we stayed on-budget. Things that we got done in the project: - Bumped out front to add walk-in closet and much bigger master bath to master bedroom. - Reconfigured entryway with a foyer/mudroom and semi-open staircase to attic. - insulated attic. It's still unfinished, but much better for storage. - new roof w/ 30 year shingles - widened dining - family room entry to be open concept. - re-did fireplace wall with built-ins, stone tile, gas insert - new paint for most of first floor - refinished all hardwood. One thing that we did to help out is that we completely moved out of the first floor as well as most of the attic stuff into a POD. TCB will readily tell you that they aren't professional movers, so go ahead and hire a professional moving firm to do that for you to clear the way for TCB to do their work. We used 2 men and a truck and were very happy with them."

One starting point to find a local home builder is to collect suggestions from friends and neighbors. However, it’s still wise to do some more research before you hire a builder. Read reviews to supplement any word-of-mouth recommendations. Check sources like Angi that have standards and criteria in place to screen the pros it lists can also help you find more reputable local home builders.
The cost to remodel a basement is between $12,100 and $33,400 for the average homeowner. The price you pay can be as little as $3,500 or as much as $50,200, depending on the size and condition of your basement and the type of remodel you're doing.
If you're doing a simple project like adding a home office to your basement, you can expect to pay anywhere from $500 to $3,000. However, if you're adding a bathroom, which is an extensive project, you can expect to pay between $6,600 to $16,500.
Yes, most states require home remodeling contractors to be licensed, and for good reason. Hiring an unlicensed home remodeling contractor could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
The average cost to enclose a patio to create a sunroom is around $5,000, and prices generally range from $3,000 up to $10,000. The price you pay will depend on the state of your patio and whether it needs repairs or additional structural support, the quality of the materials you choose, the size of your patio, and whether you plan to run utilities into and finish the sunroom. The price for a fully finished patio enclosure could run up to around $20,000, while you might pay just $2,500 for a screened-in porch.
The cost to build a detached garage for two cars costs about $26,400 on average. Prices range from $19,200 to $33,600, depending on your location, the garage size, height, materials, and site prep required. Additional cost factors include any plumbing, electrical wiring, and insulation. If you need to build a concrete foundation for a new detached garage, you can expect to pay $1,000 to $8,600 for this essential addition.
