"Platinum General Construction LLC was contacted after two initially hired contractors were incompetent in providing the remodeling services needed for our bathroom remodel in Dec/Jan 2025. Platinum stepped in and completed the work on time and as quoted. David was our primary contact. He was great as respects communication, working through issues, and coordinating with subcontractors. The remodel included heated tile floors, a curbless shower, toilet install, and beautiful tile work. We were pleased that Platinum got our project back on track and finished after dealing with the mis-steps of our original contractors."

"We hired WPC to construct an addition our home. The project started well and we were generally happy with their work. There were several points where their oversight of subcontractor work was lacking, including a major framing mistake and roofing material that did match the rest of our house. Their invoices lacked details and upon requesting receipts and hours breakdown it was clear there were some discrepancies. For example, we were charged 8 hours for two 20 minute inspection appointments. Getting towards the end of the project it was clear that they were going to far exceed the budget our contract specified and work was very sporadic, dragging the project schedule out unnecessarily. We had a disagreement about how they were applying their margin to a new heating system in our existing home (i.e. not part of the addition), which eventually led them pulling out of the project. Had they not done that, we would have fired them due to their poor performance. We had a neighbor who hired them for a DADU project and he had a similar complaint about them not being able to deliver at the end of the project. We were lucky to find another contractor that actually showed up to do the work and did exactly what they said they would do."

Addition to existing structure building services FAQs
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.
