"I recommend Dennis (Harmon & Harmon) in the strongest terms for a renovation, upgrade, or any other construction in your home. I hired Harmon & Harmon for some upgrades/repairs in a home I recently bought, including a major renovation of my attic (dark, unfinished space, bare studs) to be a fully finished room. Dennis saw the potential of the attic (which was huge & very open). Now fully finished, the attic has a beautiful composite wood-grain floor, finished walls, recessed lighting, full climate control with a mini-split, and he was even able to add a window with a view to the water. It is a huge room that now functions as a TV room for the kids with a big sectional couch, one corner is an extra closet/storage nook for my wife, & the gabled window area has table & chairs for reading and enjoying the view. Best thing about Dennis... 100% follow-through, 100% satisfaction. If I had an issue, he fixed it, period. Outstanding professionalism from start to finish. A+, 10/10!"

Despite our growth, we steadfastly adhere to our fundamental mission: "To achieve ongoing success by ensuring client satisfaction, delivering high-quality services, and upholding genuine integrity, all of which culminate in the finest craftsmanship."

"The whole experience was excellent. Chris when to give us a bid. He was very knowledgeable. He told use about the triangle of stove, fridge and sink and flow. He suggested a long narrow window to replace the tile backsplash on an outside wall. It was a great idea. When sit at the new bar between the kitchen and the living room we look out into our backyard. Itâ s beautiful. The guys that did the work are extremely work oriented. They are constantly working. They were thorough, knowledgeable and open to our suggestions and requests. We wanted an additional can light no problem. They were great. They cleaned up every day before they left. They would tell use when they were going to arrive and what they planned to accomplish that day. I have old siding on the outside of my house. They matched it perfectly when eliminated a window. The price of the cabinets was a lot more reasonable the other bids and theyâ re beautiful. What I mentally pictured in my mind on how it would look and the ease of preparing meals in the new kitchen were so wrong. Itâ s at least 10 times better. It still has the same physical dimensions but how itâ s played out. It seems so much bigger. I highly recommend them for any project you need done"

FAQs for addition to existing structure building service projects in Olympia, WA

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.
