Click here for the Retrofit Order Form!

Olsen Construction would like the opportunity to fulfill your retrofitting needs. The services we offer to Realtors, Sellers, Buyers and Escrow Companies during the point-of-sale process are provided to facilitate the transition and satisfy requirements at close of escrow. We also help homeowners to safeguard their homes when no sale is involved. To retrofit a property means “to provide with parts, devices or equipment required by State and local ordinances, which were not in existence or available at the time of construction or prior sale”.

In the City of Los Angeles some of the required ordinances are:

  • Smoke detectors
  • Ultra low-flush toilets and low-flow shower heads
  • Water heater strapping and bracing
  • Tempered-glazing for sliding glass doors
  • Seismic gas shut-off valves

In the City of Santa Monica the required ordinances are:

  • Smoke detectors
  • Ultra low-flush toilets and low-flow shower heads
  • Water heater strapping and bracing

Ordinances vary for some of the surrounding cities, but most are the same as the County of Los Angeles and require:

  • Smoke detectors
  • Water heater strapping and bracing

Olsen Construction inspects the designated property and submits an estimate before any work is done. Upon acceptance of the estimate, the retrofitting is done and a detailed statement affirming that the property meets regulatory codes is sent to owner/agent and to escrow together with a Certificate of Compliance.

Olsen Construction is highly trained, personable and efficient. We offer competitive prices, and pride ourselves on our excellent service. The quality of service has led to numerous references from well-established individuals within the real estate industry, resulting in a long list of satisfied, repeat-business clients.

Our goal is to provide each of our clients the best service possible… To continually meet or exceed your expectations!
Tankless Water Heater
Go Green, Go Tankless


No Storage, No Shortage

The most popular advantage of tankless water heaters is that you will never run out of hot water. This is because tankless water heaters heat water on demand, and that means no storage or shortage of hot water. Imagine the luxury of always having hot showers or filling up a Jacuzzi hot tub and still having endless supply of hot water for the rest of your household needs. It’s about time your home had equal supply of hot and cold water.


Hot Water For Any Size Home

Tankless water heaters are capable of supplying more hot water than traditional tank-type water heaters. With Noritz features such as Quick-Connect and Multi-System, our tankless water heaters can meet any hot water demand of today’s homes.


No Dirty Tanks

With a tankless water heater it heats water as it passes through the unit, so you will never have to use hot water that has been stored in an old rusty tank. As the years pass by, traditional tank-type water heaters start to rust and build-up scale inside the tank, which is where your hot water is being stored for use.


Lower Water Heating Costs

With a tankless water heater, you'll save energy and thus, money. Our on-demand systems require no pilot light and can save about half the cost of your current water heating bill since there is no re-heating of water as with traditional water heaters.


Tank Water Heater Waste

It is estimated that 7.3 million traditional tank-based water heaters are disposed into landfills each year in the United States. Keys to preventing the production of waste is to practice the 3Rs: Reduce, Reuse and Recycle. With a tankless water heater you can be sure that the 3Rs are in place.

Tankless water heaters are extremely durable, lasting longer than traditional tank-type water heaters, and requiring little maintenance over its lifetime. Olsen Construction wants you to feel comfortable with your tankless water heaters so we back them with one of the best warranties in the industry.

Reduce, Reuse, & Recycle Reduce The most effective way to decrease waste is to prevent it in the first place. Purchasing durable, long lasting products is a means of waste prevention. With a tankless water heater you can rest assured that you will be getting an extremely durable unit. Reuse Reusing a product may actually be more beneficial than recycling, because it doesn't require any reprocessing before it can be used again. Every part on a tankless water heater is replaceable, so you won't have to worry about replacing the entire unit if there's a malfunction. Just repair the damaged part and your unit is as good as new. With a tank water heater you're more than likely going to have to replace the whole thing. Recycle Recycling turns materials that would otherwise turn to waste, into valuable resources. The main components of a tankless water heater are recyclable, so there will be a significant decrease in waste materials.
