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."

We are a local Whatcom County family run business who specializes in residential remodels and additions. No project is too big or too small. We can do anything from siding, decks, fences, to bathroom and kitchen remodels. We also do ADU's DADU's and can help facilitate the permitting process.

"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!!"

Fire Sprinkler Companies questions, answered by experts

By carefully planning the layout and using quality components.

You might, depending on where you live. Backflow preventers ensure that water only flows in a single direction so that the dirty water from your home and irrigation system doesn’t contaminate your fresh water supply. Many municipalities require you to have a backflow preventer if you have a sprinkler system. But even if you don’t legally need one, installing a backflow preventer can give you peace of mind that your dirty water isn’t mixing with your clean water supply.

If you don’t currently have an irrigation system, cost is one of the biggest drawbacks of adding drip irrigation. You’ll likely spend several hundred dollars to set up your system. Plus, installation can be tricky—especially if you have a large or sloped yard. Drip irrigation systems also need ongoing maintenance, which you don’t really have to deal with if you’re just using a garden hose or portable sprinkler to water your lawn.

The nozzle is a small piece on top of a sprinkler head that offers some control over the spray pattern and spray height or distance. Typically, homeowners can make small adjustments to the spray by twisting the nozzle on top of the sprinkler head. Be sure to check your sprinkler head’s manual instructions before making adjustments.

You can find irrigation lines whether you dig or not. If you decide to dig, do so near valve boxes and around sprinkler heads. Once you find the first pipe, you can map the system from there and use spray paint or tape to mark the pipe layout throughout.  

If you don’t feel like digging, aside from getting a map from the maker of the irrigation system, you can still find irrigation lines by locating the valve box and following a line back to the head sprinklers. You can also use a water-detection device or a metal detector, which will work if the lines have metal tracer wires.
