"Our experience is identical to what other reviewers shared. And yes, you should run from this company as fast as you can. Do not buy what Abraham shared that the payment must be made when the inspection is passed. Check the Business and Professions code yourself, the payment only needs to be made when the job is completed. It is very COMMON that the job is not even done or poorly performed even the inspection is passed. Here are the issues that multiple families including us run into with this company:: The project was delayed for over 9 months. No one manages the job. He often employs young men from his own Jewish community. They are enthusiastic but had no prior experience. The worse part is that they don't get paid. Two of them even set up a new construction business knowing Abraham will never pay them. Subcontractors can put your house on lien also. Many reviews you see on Yelp, Google, Angi are NOT genuine. Even the references are fake with hindsight, we were given 2 references. One reference shared the exact same accent as the PM. The other reference was initially happy with their work, but then reached out to us and shared a similar horror story with them like what we experienced. You will lose a lot of $$$ on materials as the subcontractors will somehow leave a thousand dollars worth of quartz at home. Maybe they want to compensate for the money Abraham owed them? Let me tell you, reordering materials is not fun."

This is Rupert and my team at Summit Deck Doctor. We offer Deck Finishing, Deck Repairs and Deck Build within 25 miles of Los Gatos. We know you have a choice and hope you will choose us! There are three things that make us different from other contractors: LOOKS BETTER, LASTS LONGER, JOB DONE. Here’s why: 1) LOOKS BETTER. a. We avoid lap marks where two layers overlap. Not every contractor understand the import of maintaining a wet edge to avoid these dark marks on your deck. B) we stain the edges of the boards so you don’t get “zebra stripes” – very visible and distracting drips down the sides of the boards (other contractors charge extra to fix this), c) we use lots of drop cloths to avoid spills (so no more careless mess below the deck). 2) LASTS LONGER. a). We use reliable durable stains, not the cheapest ones (unlike other contractors), b) we use hybrid stains, not environmentally-unfriendly and smelly oil stains which have very poor durability. c) we apply stains in the shade or the cool of the evening to allow stain to sink in and so they last twice as long (unlike contractors who don’t seem to read the instructions on the can which say “don’t apply in sunshine”). 3). JOB DONE. a). I will be coming to give you the quote and I am the owner (unlike other contractors who send a sales guy who might make promises the company can’t keep). b) I will write up the quote then and there (no waiting a week for a contractor to type it up), c) I will be calling you every night during the work to make sure you are happy. IN SUMMARY: We put special care into refinishing your deck and handrails so they look stunning, in giving you twice the durability of other contractors, and in getting the job done efficiently. We believe we halve the cost of refinishing your deck because we apply stains in a way that doubles the durability of your deck finish which means you have it done once not twice, saving you money. WANT TO KNOW MORE? Download our 90 page book "Deckology; The Art & Science of Deck Finishing and Carpentry" which explains the refinishing and carpentry process. (Look for deckology33.pdf). WE WON’T LET YOU DOWN. We have worked on over 1000 decks, have been in business for 12 years, are accredited at A+ with the Better Business Bureau, are a Super Service Award Winner at AngiesList.com with over 50 reviews, have a 5 star rating on Yelp with over 38 reviews, and are certified by the EPA for removal of toxic finishes. We are licensed, bonded and carry workers compensation insurance for your protection. We offer Fixed Prices, which include all labor and material expenses; this gives you peace of mind with no hidden costs. Our payment schedules are all milestone-based, which means you pay only when a milestone in work is achieved, providing you with reduced risk and more peace of mind. Contracts are proper written contracts; nice and clear, and professional; how it should be. Unlike other contractors we work on your job continuously - no "dragging it out;” most jobs can be completed in 4 days' continuous work. We leave you a partial can of stain once we have finished so you know what stain we used, when it comes time to refinish the deck in the future. BEFORE YOU CALL. If you really don’t know what these things cost, then it would be helpful if you can estimate the size of your deck by pacing it out – so we can give you a ballpark estimate when you call PLEASE NOTE: Don't forget to read our reviews in both "Deck Maintenance" and "Decks and Porches" categories. Summit Deck Doctor is a DBA of Experiventures, inc.

"Our large deck was sorely neglected - no maintenance in at least 8 years - and I worried it was beyond help or would be cost-prohibitive to rehabilitate. Rupert and Michael breathed new life into it! Rupert (company principle) is very responsive, and he was able to give a quick informal estimate based on some photos and I texted. This made it very easy to start working together right away. Now the deck looks beautiful, and they were able to stain our wooden deck furniture to match. Great makeover for our deck and lovely folks to work with!"

FAQs for shelter or outbuilding building service projects in Ben Lomond, 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.
