SkyBlue Builders Inc., started in 2001 focusing on Residential New Construction. After gaining all this experience the family business decided to focus on Siding, Windows, Doors, Seismic Retrofits, ADU's, Decks, Painting, Complete Interior Remodeling, & General Construction. We service Residential & Commercial clients.

"SkyBlue Builders Performs Quality Work SkyBlue Builders is a Five Star High Quality Siding Construction Company, and I recommend them. My thirty-year- old home is in a rural environment. with a humid atmosphere. The siding on my home was worn by the salt air and moisture and needed replacement from the eaves all the way to the foundation. I chose SkyBlue for three main reasons: 1. Siding is all they do, and they have specialized in it for 19 years. 2. They are rated A+ by the BBB and have had no complaints regarding their work. 3. I viewed online photos of their previous jobs and was impressed by the quality of their work. My experience with SkyBlue was positive from beginning to end. Every day they showed up at 8 A.M. and worked until 4 P.M. when they began cleanup. Every day they put away their tools and cleaned up the work area. At the end of every day they made sure that my driveway was clear, so I could pull my car out of the garage. The workers were always polite and cooperative and responded positively to homeowner concerns. Here are some examples of their work: 1. SkyBlue provided protection against animals. Our rural community has many wild creatures nearby: Bats, coyotes, skunks. raccoons, opossums, mice, and gophers abound, These animals are always in search of a warm and dry haven such as a basement. Over the years, invading animals chewed the wiring of my HVAC dampers, ruining the home heating and cooling controls. I spent thousands to repair the damage. I reported this history to SkyBlue. They replaced the old substandard and ineffective basement vents with quality new vents. They were also careful not to leave any vent opening exposed during the repair. SkyBlue also replaced my costly, old, substandard roof eave “chicken wire bat control,” installed by three separate “bat experts.” SkyBlue installed new, high tech, high quality solid construction in the space between the fascia and siding. Now there is no space for the bats to occupy. 2. SkyBlue used quality materials and did quality work: SkyBlue installed Kelleher Double Pre-Primed Siding so that both sides of the siding and trim are pre-primed with two coats of prime and thus are well protected. SkyBlue reset every single nail in the new siding and trim, and then caulked all holes. Finally, they sanded the caulking, effectively hiding every nail. Looking at my house, you can’t see any joints where two siding boards come together. You cannot see any nails. What a refreshing improvement from the original construction ! SkyBlue then applied two color coats of High Quality Sherman Williams Paint, for a total of four coats of paint. The result is spectacular. To see their work for yourselves, go online and look at photos of their previous jobs. 3. SkyBlue found and repaired old wood damage and previous poor construction. The repair work is better than the original construction. Their workers are experienced, friendly, and will listen to your concerns. The people who hire SkyBlue are people who want quality construction with attention to detail, and a beautiful result."

"⭐ 1 Star – Unsafe, Unlicensed, and Untrustworthy Contractor I hired Fernando Soto / 360FSC Inc. for an ADU and home extension in Millbrae, and it has been one of the most stressful and costly experiences I’ve ever gone through. From the start, Soto relied on unlicensed workers for critical trades. Electrical work was unsafe and failed inspection — indoor panels were installed outside, wires were left unsecured, and essential safety breakers were missing. Plumbing was just as bad: instead of replacing the pipes as I requested on day one, his crew tied old cast iron, clay, and PVC together, even forcing larger pipes into smaller ones. This caused sewage leaks and backups. Independent inspections later confirmed major issues: Flooring – failed inspection and needs to be completely redone. Foundation – the new extension has already sunk by about 3.5 inches, creating serious structural risks. On top of that, the project stalled for months after May 19th, billing was vague, and Soto even threatened to rip out work I had already paid for. He hides behind a P.O. Box in Belmont instead of a real address, which says a lot about accountability. This contractor cuts corners, uses unlicensed trades, and leaves unsafe work behind. Do not make the mistake I did — avoid Fernando Soto and 360FSC Inc. One more red flag: a glowing “review” on this page was written by Rachel G — who is actually tied to his business. That tells you everything about how much weight to give positive reviews here."

FAQs for shelter or outbuilding building service projects in San Francisco, CA

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.
