Portland Retrofitting Contractor

We serve Portland Metro Area, Vancouver, and all surrounding cities.

There is increasing scientist research to suggest the next earthquake “Big One” could come to the Pacific NW region at any moment. Experts have being talking about a Portland earthquake to happen anytime, which is why our residential retrofit programs aim to ensure these type of buildings are in compliance with new technology and protected from any future seismic event. Building retrofitting is a very necessary step in the growing effort to make Oregon communities safer, with more houses and buildings across the state adopting similar upgrades. Give us the opportunity to be your Retrofitting Contractor and we will work hard to help your home and your family to have a better chance of surviving an earthquake.

Seismic Retrofit Benefits

There are many benefits to building owners starting their retrofit sooner, rather than later to avoid major damages if a Portland earthquake finally happens as predicted by experts:


Retrofitting protects lives and your assets

Reduce Liability

Retrofits help reduce an owner’s liability for injury or death in the event of a quake

Lower Insurance Costs

Some insurance companies offer more favorable terms for retrofitted buildings

Save on Construction Costs

Construction costs will rise with demand after the “Big One”

The possibility of an earthquake is a reality for many Pacific NW residents. That’s why it’s important to make sure your home is properly reinforced to resist seismic forces. Homes built before 1985 are especially vulnerable to earthquake damage, but buildings of all ages and styles can benefit from reinforcement with approved structural connectors and other structural reinforcement.

JAM Concept Remodel is a local retrofitting contractor for seismic retrofitting and earthquake retrofitting services, and we can help you get right preventative measures for your home’s foundation. If you’re concerned about your home’s foundation and are interested in seismic strengthening, call us today at:  503-490-5541

What is seismic retrofitting?

The seismic retrofitting process involves the installation of engineered metal connectors and other reinforcement materials at key stress points throughout your home’s structure. The specially designed hardware includes hold downs, anchors & anchor bolts, strap ties and framing angles. Wood blocking and structural sheathing may also be incorporated into many earthquake retrofitting packages.

As your Retrofitting Contractor our goal of the retrofitting process is to counteract three main earthquake-induced forces that can cause major damage to a building: racking, sliding and overturning. In engineer-speak, the retrofitting process transforms a building with loosely connected parts into a unified structure with a “continuous load path” that extends from the building foundation up through the walls and all the way to the roof framing. Our experienced crew will utilize an impressive arsenal of seismic connectors to keep your house structure together in spite of seismic forces that can easily tear an un-reinforced house, ADU or Basement apart.
