"After many roofing estimates that were incredibly high and came with either no financing or high interest financing, I stumbled upon Zen Builders. Simon was attentive, knowledgeable, and on top of his game. My roof was completed in three days, it's beautiful, and there were NO LEAKS when the rains came a few days later. The workers were professional, considerate, and the clean up was amazing. No trace of having construction in my yard. Because I was so happy with the work, I mentioned to Simon that I would love to have him come back and do a few more projects. I ended up with an even better financing option (both loans are well-within my budget) and a GORGEOUS new patio cover complete with a surprise ceiling fan in the middle! The patio is now white, and they painted the trim of my house to match. They also fixed my heating/AC ducts, insulated my attic, and for free, added plywood, so I can actually store items up there. I have never had an issue getting ahold of Simon or his sister, Kineret (Kerry). When there was an adjustment needed to the air ducts, the workers came out quickly (amid the COVID-19 quarantine) and simply fixed it! I couldn't ask for more! All work took less than a month to complete and I never felt pressured, ignored, or bamboozled. I have recommended Zen Builders to many of my friends. I hope they recover from the imposed quarantine to continue to provide excellent service."

"A GREAT experience! I chose Top Leader Construction to work with me on the renovation of my former childhood home, and as an Interior Designer I had a clear vision of what I wanted to create and achieve. I knew that I needed a top-notch, experienced and detail oriented builder who would be able to help me reach those goals, and truly my dream, for the house: creating the best of the new while respecting and honoring the past. Zack and his team were absolutely the only ones for the job! Their professionalism, courtesy, focus on quality, and ability to deal with the unexpected changes and issues that will inevitably arise on old house renovations, were exemplary. Zack and his staff were always responsive, communicative and available to work through any issues. The house is a living embodiment of the dream I had imagined, and that's very much due to the efforts and expertise of Top Leader Construction. As an interior designer, I emphasize quality materials and customer service, and Top Leader delivers that and more. I look forward to future collaborations with Zack, and would refer him as the only choice for any client seeking to renovate or build!"

They have done our garage roof, the main roof on our house, they have put in new roof for my town home, and all looks beautiful. The team is very prompt response. The crew is very friendly and professional. I will use them again for future needs."

"Cielo Construction has completed several projects in our house including the remodeling of our guest bathroom, master bathroom, kitchen and living room area. The design and remodeling was a custom European style/modern while the bathroom included a walk in tile shower, jet shower system, home automation and more… part of the design was to reposition the door opening for a much better use of space. Cielo construction staff helped us by selecting all of the finish materials including the tiles, upper and lower cabinets, accessories and more… including the color/style of the paint. Mike included also in his work the remodeling of the guest bathroom, drywall, type of texture, baseboards etc. He has excellent, professional craftsmanship and creativity skills. Cielo constructions approach and talent to meet our deadlines were fantastic and he was able to finish the remodeling project on time. We definitely recommend Cielo Construction and all the involved people that worked at our house for any type or style of construction or remodeling projects. We are very pleased with the completed project and we will hire them again for more upcoming projects. Thanks Cielo construction for a great job from a very happy customer."

"Mike (Moshe) BenHaim and his company America Green Builders were very professional. They have different crews for different things and the service was just amazing, I couldn’t ask any better than that! We’ve replaced the old windows with vinyl windows. Removing the old insulation in the Attic and install new 12 inch high (R38) insulation. Painting the exterior walls and wood eves and trims with life time energy efficiency paint. Replacing the carpet with laminate flooring (about 2,000 sqf). Mike is very special person and very honest. I would highly recommend him and his crew. He’s fair, responsible, and always available. We become good friends and now he’s going to replace my A/C unit ducts and adding more solar panels to my house."

FAQs for shelter or outbuilding building service projects in Claremont, 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.
