areas of the house experience significant failure.

Portland and Seattle being hubs of seismic activity and full of historic homes,
residents can especially benefit from structurally reinforcing their houses with
SFW Construction.  Our professional teams

Construction can help you complete these important steps…

Though not always implemented as
a total, each one of these strategies offers you a peace of mind and adds a
layer of insurance for your home and household in case of any earthquake


Foundation Anchors: Our professional seismic-retrofit
team connects your basement wall to
the foundation to keep the house in place, despite any movement in the soil that
may occur. Vertical bolts are
used where space allows. If space is limited our crew will then instead use Foundation brackets with horizontal bolts.

Framing Anchors: To preserve stable
framing within your residence, the SFW Crew will attach rim joist to mud sills and floor joist to mud sills.

Water Heater Strapping: An easy but
often overlooked solution, Water Heater Strapping prevents one’s heater falling and causing water
damage. This can also be used as emergency drinking water source!


Gas Emergency Shutoff Valve:   The SFW Team is happy to install this feature
as it greatly reduces the risk of structure
fires during seismic activity.



Shear Wall: This technique
is when our crew at SFW Construction carefully adds new layers of plywood to the basement wood
frame.  This newly created “Shear Wall”
(a.k.a. Cripple Wall) then protects your home against any possible side-to-side


Improved Masonry: Even the hardest of
materials are known to wear and weather over time. Your footers and basement walls made of concrete,
brick or stone should be evaluated by our team and reinforcement or replaced as



Post and Beam Reinforcement: For this step, our SFW
Construction crew add Brackets
which contribute resistance and prevention of potential side-to-side motion your
home may experience.


Porch Strengthening: Especially important
in our area, this practice allows our team at SFW Construction to add new posts and beams inside historic box beams
and hollow columns.  This reinforcement works
towards preventing a collapse of the porch during possible earthquakes.

Chimney Banding and Bracing or Removal: Chimneys are
important for staying warm and smoke-free in the winter, but the risk of collapse is prevalent which has the
possibility of causing injury to occupants and damages to the structure. Our professionals
ensure that your chimney structure is up to code and can withstand future


How Disruptive is the Retrofitting
Process with SFW Construction?

If all the work is to be done in
crawl space areas, which it is in most cases, the disruption will be minimal.
This usually consists of no more than a week at your home and some noise coming
from under the house.


You will be requested
to assist with SFW Construction’s team during the retrofitting process in the
following ways…


Residents will be requested
to provide access to the areas of your home that needs to be inspected during
our initial visit.


Household members
who participate in decision making regarding your home will be asked to sit
down with our Project Manager for further information and a discussion detailing
how we will implement our improvement plan.


If you have any
valuables and personal items located in the expected work areas, you will be asked
to temporarily relocate these matters out of the way.


You will be asked
to prepare and arrange for the fitting of smoke detectors in bedrooms and
hallway areas of your home if this activity is not already completed.


Lastly, you will be
implored to have an adult member of your household be available during the
final inspection, which may require you to be at home most of a full day.
