We are a new local business with 30 years of experience in the industry. We can act as General contractors on a large project or take on smaller sub-contracts. Depending on the job we bill for time and materials, or a lump sum total with 40%-50% due at signing of the contract

"Paul Burlingame (and team) constructed a basement garage and attached ADU on the side of our 100 year old house - no small feat at all. Initially we were a little guarded because of all the horror stories you hear about shiesty contractors, but our experience with Paul has been nothing but positive throughout the entire build. He has a keen attention to detail and values good quality work. For example, there were a couple crucial details that were not described by our engineer, and Paul worked hard to determine the right course of action. In the end, what he came up with was better than we could have imagined. Not only is he personable and a knowledgeable contractor, he has an eye for aesthetic which was a delight as we discussed design options, from trim details to pergola hardware. In the end, Paul and his team built us a stunning 800 sf 2 story ADU and 400 sf basement garage, that feels spacious and contemporary while beautifully tying together with the exterior of our existing 1920s Tudor Revival home. I can not recommend Burlingame Contracting enough! Thank you Paul!!"

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

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.

A burst pipe can cause hundreds or even thousands of dollars in damage. It could flood your home, which can destroy many of your belongings. It could also ruin hardwood floors and carpeting, requiring you to replace your flooring. Finally, mold and mildew form very quickly after high levels of moisture have been introduced to a space; this is not only costly to remove but also bad for your health.

Common drain issues include slow-running drains, whether in a sink or shower, clogged drains, a bad smell, and water backing up into a sink, shower, or bathtub. Causes range from hair, grease, roots, or toilet paper clogging the drainpipes to flooding outside the home, which prevents sewer lines from draining properly.

Pooling or standing water in your basement should be cause for alarm and action. This indicates that there is a leak or a drainage issue, and until you repair the root of the problem, the situation will only happen again or grow in severity. It’s important to deal with water damage as soon as it occurs.

Mold and mildew are the things in basements that actually cause the musty odors, but moisture is the underlying issue that causes mold and mildew growth. Addressing moisture and water problems and then removing materials that are moldy are some of the best ways to get rid of the musty odors. Preventive measures after that—like installing air fresheners and a dehumidifier—can help keep musty odors from returning.
