"I would HIGHLY recommend US builders for any home remodeling project. I saw the quality of their work when they did a total kitchen remodel for my neighbor. The quality was top notch so I hired them to repair the outside and inside of my home when a car, traveling at a high rate of speed crashed into the front of our home. Workmanship is superb, they arrive on time, have the skills and resources to do the job, and they clean up at the end of every day. They same workers were at the job site start to finish, they could easily problem solve unique issues. They repaired and painted drywall, put on new siding and new windows, replaced ceramic tile in the foyer, and "sistered" support beams around the stairwell. PLUS they worked seamlessly with the insurance company!!!!"

"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 signed a contract for work to be completed in 4 weeks. 4 Months later, work was finally (mostly) done - but only with extreme nagging on my part and excessive excuses and push back. The contractor only came to the project site if his sub-contractors created an issue (which was often). They dropped my A/C unit down a 10 foot hole, they didn't finish half the projects they said they would and completed the other half incorrectly based on hand drawings and gestures because neither the contractor or I could speak the same language as the sub-contractors, they made promises to show up and never did. Worst of all, they used design plans from a previous contractor that were approved by the city - but didn't use those plans and never updated the plans. The city inspector came and did not pass the project due to this discrepancy, but Vladimir told me it had passed. The city told me the permit expired. So - now Vladimir won't answer my emails and I have to pay someone else to fix it all."

FAQs for addition to existing structure building service projects in Leesburg, VA

Converting an existing space into a laundry room is more affordable than building a new addition. While new additions start at $5,000, renovating an existing space for laundry use can begin at $1,300. 

Your specific costs will depend on whether plumbing and electrical connections exist nearby, the quality of finishes you select, and whether any structural modifications are needed. Always budget extra for unexpected issues, particularly in older homes where hidden problems might surface during renovation.

The smallest practical size for a new laundry room addition is 35 square feet, which provides enough space for basic appliances and minimal storage. For renovations utilizing existing space, smaller footprints might work with space-saving solutions like stacked appliances. 

A standard-sized laundry room of 60 square feet offers more comfort and functionality, allowing for counter space and storage cabinets. The optimal size depends on your household needs and available space.

Yes, adding a laundry room requires several permits, particularly for new additions. You'll need building permits, plus specific permits for electrical work, plumbing installations, and possibly HVAC modifications. 

Requirements vary significantly by municipality, so consulting with your local building department before starting work is essential. Proceeding without proper permits can result in fines, mandatory removal of completed work, and complications when selling your property.

The timeline for completing a laundry room addition varies based on project complexity, contractor availability, and permit processing times. Factors that can extend the schedule include material delivery delays, weather conditions, and unforeseen structural issues discovered during construction. 

Renovating an existing space often requires less time than building a completely new addition. Working with an experienced contractor who can coordinate various tradespeople efficiently helps keep your project on schedule.
