"He was very nice but the work has still never been completed and he has totally stopped replying to me. The part that was completed was mostly good except that his dry wall guys ruined an antique hope Chest by putting carry out cups on it. I waited over a year and a half to file this review with the hope that the work would be completed."

"Weaver did very well with our basement finishing. They did get the way we wanted things done, which was a bit unique, but they did miss a few things, like not understand we were going to take care of some things that were non-standard ourselves (because they were non-standard.). They also did leave us hanging a little at the end - we still never got our light switch at the end of the stairs hooked back up to the light, nor found out how to change the cam lights, but at some point I just gave up, cause they were kinda done with us after they got their last payment. Generally good to work with, they did have a bit of a time getting workers due to COVID, and there were some small less than desirable messes left. But thatâ  s small compared to the overall work, which was good. So Iâ  m pretty happy overall."

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.
