"Our journey with Spartan Contracting began in the early summer of 2019. We had just fired another contractor in the middle of a bathroom remodel which had turned into an unqualified disaster. The project was putting a second bathroom in the basement of our 65 year old house, and remodeling the existing upstairs bathroom. The contractor we had hired on the basis of a friend's recommendation had just stopped showing up with the job half done. As we should have done to begin with, we interviewed three contractors and went with Spartan. I wish we had found them first! Levi (owner) and Mark (foreman) went over the existing and projected work in detail, gave us a thorough estimate, and an honest assessment of what needed to be done. Mistakes had been made by the previous contractor and subcontractors, which had to be rectified. As well, the previous contractor had not obtained the appropriate permits for the extensive job, which could have become a serious issue when it came to selling the house in future. Everything that needed to be done was explained in detail at each step. Spartan was definitely challenged by the fact that the house is 65 years old. As work progressed, not unexpectedly, issues turned up which had to be addressed to bring electricity and plumbing up to code, to reinforce aged infrastructure, to correct haphazardly done "upgrades" by the previous homeowners(s), as well as the mistakes made by the previous contractor. At each step of the way, they explained what needed to be done and why. We wanted everything to be done correctly, to code, and in a quality fashion. This is what we got. The downstairs bathroom had been a particular challenge due to very old plumbing, and dealing with a lift station to the septic system. Each challenge was met and solved. Excellent plumbing and electrical subcontractors were brought in. Both bathrooms turned out beautifully. We were so pleased that we decided to go ahead with a kitchen remodel, as well as adding an arctic entryway and replacing poorly built deck and fence. Levi and Mark worked with us to design a kitchen that would fit into a somewhat challenging space. Again, as the project proceeded, necessary improvements and upgrades had to be made. Work proceeded through the winter with its cold weather challenges. And then..... the pandemic. Spartan was hampered by supply chain standstill for months, and the general systemic issues we all death with starting March 2000. They did what they could, when they could, but the project stretched far longer than any of us anticipated. Our project finally finished this summer. The results are beautiful. We went from having one old and kind of disgusting bathroom, and a dysfunctional kitchen, to two beautiful bathrooms, a kitchen we love to cook in, and a much appreciated arctic entry. I can't say enough about Spartan's quality work, professionalism, attention to detail, and working by the book as far as codes, inspections, and permits. As well, Levi and Mark had to accomodate the choices and demands of two opinionated women (me and my daughter) on what we wanted. Spartan went above and beyond in so many ways, often working 7 days a week, and did extra things like bringing space heaters over when our furnace died, and helping keep our chickens warm in winter. There are many more projects we could embark on for our old house, and we will certainly have Spartan move forward when we are ready. After working on our old house for three years, I like to think they have a bit of affection for it! Thanks to Levi, Mark, Wendy, and all their excellent assistants and subcontractors."

"Jim, Steve, Clint and the rest of their crew were great. They would quickly respond to changes or fixes required to get the job done right. Finished product is everything I expected. After working with some flaky contractors in the past, Crestone was a refreshing group to do business with.

"Jeff does great work from start to finish. He listened and understood the changes we wanted. He researched the most economical way to obtain the desired results without jeopardizing quality.
Jeff was able to build the indoor slide for the children's area by simply looking at a picture. He also made sure that every aspect of the slide was safe for the children to play on.
His finish work is excellent! We were especially pleased with the new offices and conference room. We couldn't ask for better sheetrock, mud, tape and texturing.
Jeff is a hard worker. He is punctual and has no problem staying late until the job is done.
My husband and I plan to use him for finish work on our cabin.

FAQs for shelter or outbuilding building service projects in Anchorage, AK

A bomb shelter is an abode built to withstand disaster. Bomb shelters may refer to a space or bunker that can protect inhabitants through a hypothetical nuclear attack, apocalypse, or any other massive crisis. People usually build bomb shelters underground and stock them to live there a few days to a month at a time. Doomsday bunkers accommodate long-term living rather than just through a short crisis.

Builders construct bomb shelters with reinforced steel, box culvert, concrete, or other durable materials (but many professionals do not recommend shipping containers, as they’re not designed to live underground. If building underground, you’ll first have to excavate land before building the actual structure. You’ll have to implement air and water filtration systems, septic systems, and power supply.

It takes a lot of experience to safely and legally construct a bomb shelter, not to mention make sure it’s fit to live in for extended periods of time. It’s best to talk to a residential structural engineer near you for proper guidance.

The current standard filtration systems require filtering both air and water. For air, you’ll want an NBC filter system, which both domestic and international producers make. NBC stands for Nuclear, Biological, and Chemical, which filters out all three. If you’re only building your shelter for natural disasters, chemical attacks, and biological attacks, you may opt for the less expensive HEPA filter system. 

Water filtration requires the same level of care. You’ll likely want to have a large water storage capacity to survive short-term disasters. For long-term living, you’ll want to have a water filtration system.

Rising S bunker prices depend on the size, ranging anywhere from $20,000 to $9 million. Their least expensive model is 96 square feet while their most expensive model has a gym, swimming pool, hot tub, and bowling alley.

  • Mini: $45,500

  • Standard Bomb Shelter: $67,500–$109,500

  • Silver Leaf: $140,000–$182,500

  • Admiral: $180,000–$500,000

  • Xtreme: $450,000–$780,000

  • Xtreme Bunker Complex: $840,000–$1,830,000

  • Luxury Series: $3,800,000–$9,600,000

You almost always need a permit to build a bunker on land with any type of public utilities running through it. You’ll want to check with your local building code enforcement agency to see if this is the case for your area. 

Because you’re building a structural component that often requires electricity, water, and sewage services, you’ll need to apply for permits to attach these utilities to your new property. However, off-grid-only units in rural areas may not need all or any of the permitting you’d normally find in more urban settings.

To survive a nuclear blast, you’ll need to have your bunker at least three feet underground. However, it’s usually advisable to put it further underground. To survive a close strike, you’ll want to have the bunker at least 10 feet down and with five-foot thick reinforced concrete. However, knowing exactly how deep to build depends on the size of the blast you’re trying to avoid. Most bunkers don’t need to be more than 5 feet below the ground.
