"Moises and Edward and the crew did a repair of my facia. They told me to get PVC so it would last longer. They also repaired cracked walls and ceiling and painted. They did perfect work. Did so good I kept finding more work for them because it looked so good. They are so polite and respectful and right on time. Also they are very fair with their prices and don't push for or more work. I now consider them friends. Don't waste you're time because you won't beat their prices. They can do anything too. Bathroom, kitchen, floors. I will hire them again they are the best."

"Gary and the team did a great job. My wife wanted a timber frame look to the front entrance and the guys created an amazing custom look. Gary made some design suggestions along the way, and we think they really enhanced the overall look. This is the 4th or 5th time we have used Kentstruction and I cannot say enough great things about them."

"Great! This company is professional, easy to work with, and offers a great value for the service. I did the leg work and compared them and their pricing with that of several dumpster companies and will continue to use the BullBag. Their pricing always blows the dumpsters away - BullBag doesn't charge by how much it weighs like a dumpster does AND I get to keep my BullBag. I don't have to wait for a dumpster to be delivered either."

"Fast, professional, good cleanup, amazing new look to the house. They even replaced ill-placed plywood that was making the roof uneven and reinstalled two skylights that had been put in by a previous contractor, not with the best method. Their crew was professional, removed and re-installed gutters (several others from whom we solicited bids told us they would destroy the gutters in putting on the roof. I wish I had a few more buildings to get them to re-shingle, but will recommend to family, friends and neighbors. Since they also do construction, I am looking to use them for the redo of another building. Yeah, talk to (and hire) these folks!"

"Frank is very professional, reliable and trustworthy. He always arrives on-time or early. We are very happy with the work he did in our bathroom. We already hired him to install an air conditioner in our daughter's apartment. I would highly recommend his services."

"I had a deck built from my existing deck to my above ground pool. John and his staff did a great job. John came by and gave us a reasonable estimate and some ideas of how it would be best to build the deck. The project took two days to complete. On time and very efficient. The deck came out great. Definitely call John. You will be very happy with the outcome."

FAQs for shelter or outbuilding building service projects in Baldwin, NY

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.
