"John was great initially - getting there and tackling the immediate problem and answering my calls. We had a short in the electrical heating fan/motor in the floor that was potentially dangerous and could have caused a fire so he replaced the breaker and rewired the fan/motor. However, when he left we noticed that the fan was not running in the box and he told us to detach the wires which I felt was risky and also meant the problem was not fixed. He said he would come back the following Monday to inspect the rest of the wires underneath the house and he never did. He was also supposed to send me a photo of the burned wires, a work order/receipt for my files, and never did. I texted him about Monday and about replacing the fan/motor - either to let us what it was called and we would replace it ourselves or give us the cost of replacing one or all 3 boxes. He never responded so we still have a heating system that is not fixed and perhaps dangerous if only running on two fan motors ."

At Agate & Co. Builders we have more than 35 years of construction experience working for us. We pride ourselves on our long history of outstanding craftsmanship and customer service, which is unparalleled in the industry. We remain a small construction company that performs most of the work ourselves using a few, hand-selected and highly qualified sub-contractors when needed. This consistently allows our high standards to be applied and is demonstrated in the quality of our work. We truly love what we do and look forward to helping you make the home of your dreams.

"Jim and his crew went over and above our expectations. They did a beautiful job on our new deck. When completed, they cleaned up and carted away all scraps. A truly professional job by all."

"I recently had the pleasure of working with Pedone Construction on a full kitchen remodel, and I couldn’t be happier with the results. From start to finish, the entire experience was smooth, professional, and exceeded all our expectations. Communication by Michael was top-notch—every question I had was answered quickly, and he kept me in the loop every step of the way with pictures and constant communications. Michael showed up on time every day respected my home, and maintained a clean and organized workspace. What really stood out was his attention to detail and craftsmanship. Every cabinet, countertop, and tile was installed with care and precision. He listened carefully to what I wanted, offered great design suggestions, and truly brought my vision to life. The finished kitchen is not only beautiful but highly functional and it’s now my favorite room in our summer house. If you’re looking for a contractor who delivers quality work, excellent service, and peace of mind, I wholeheartedly recommend Michael and his company. We did fill this out yesterday but just in case resending it"

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.
