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."

Addition to existing structure building services FAQs
How far you can push a room depends on the structure you choose. A cantilevered bump-out can extend 24 inches before building codes require its own footing or foundation. Anything longer needs engineered support and a permit. Check local codes or consult with a structural professional before finalizing plans to ensure your design remains safe and compliant.
Most bump-outs are completed within one to four weeks, even with minimal electrical, plumbing, or HVAC work. Their compact size means less demolition, simpler inspections, and fewer weather-related delays compared to a full-scale addition. Your contractor can provide a more precise timeline once they have determined the scope, materials, and permit schedule, but plan on having the extra square footage ready in approximately a month.
