The Great Wide Open has an excellent reputation building in San Juan County for the past six years, almost exclusively on Henry Island. My work there has been for a small community of friends and neighbors I’ve known most of my life, where honesty and professionalism is vital to my business. Recently moving to San Juan Island I'm now open to work other than on Henry. I specialize in unique builds including saunas, decks, outdoor furniture, and gardens constructed with locally reclaimed lumber, but am no stranger to new construction. I also remodel decks, roofs, and outbuildings, and enjoy building walking paths through beautiful forests. Interested to hear what you need built!

"I live in, and was primary owner / builder on a remodel addition to an old 1970’s A-frame on Henry Island near Roche Harbor. Brian was on time, focused eager to work and stay late if needed. He brought a huge amount to the table on this very tricky custom build. He did an awsome job in all respects. And was a pleasure to work with. He listened to what my vision was, offered suggestions for design, and was critical in executing the project. I trust Brian to get the job done right no matter how “custom” or complicated a design or location."

"Legacy Remodeling did an awesome job to our bathrooms and family room. It turned out beautifully and was completed on time. After meeting up with Alvaro (owner) several times to discuss the projects, we decided to hire him. The best part about this renovation was that Alvaro did the work himself with very good eye on details, as well he is very knowledgeable on plumbing, tiles, carpentry and electrical. Also, he has a great crew. Often, they worked weekends and stayed late. We were very happy with Alvaro and his crew and, we plan to hire them again soon for our next house project."

Basement Leak Repair questions, answered by experts

No, your basement dehumidifier doesn’t need to be on 24/7. While it’s an excellent tool for tackling damp, musty air, especially in humid seasons, leaving it running nonstop can backfire. Over-drying the space can mess with your sinuses, warp wood, and even crack certain materials. Instead, only use your humidifier when moisture levels rise above 50%, and then give it a break when the humidity levels drop.

In many cases, yes, a damp basement can be bad for your health. Not only can damp air affect your lungs, but it can promote mold growth and pest infestation. Mold spores can be dangerous to breathe in, as can waste particles from insects and rodents attracted to the moisture. Damp, moldy air can also move up into your living area. As such, it’s crucial to fix any basement moisture problems as soon as they crop up.

The cost of installing landscape drainage with the help of a professional can vary widely depending on factors like the scope of the project, your location, and the specific services needed. Smaller tasks, such as installing a French drain, may range from $10 to $50 per linear foot, while more extensive projects like installing a catch basin can cost several thousand dollars to tens of thousands. Obtaining multiple quotes from qualified professionals is recommended to get a precise estimate for your specific drainage issue.

Typically, a French drain can last 30 to 40 years if it is maintained properly. The life span of a French drain depends on factors such as the quality of installation and the types of materials used. However, climate and natural disasters can affect the life span of a French drain. Regular maintenance and inspections can help prolong the drain's life span.

Waterproofing or encapsulating protects against moisture, preventing mold growth and structural damage. These services also enhance energy efficiency and improve air quality by keeping humidity levels in check.
