Foundation Repair

CG Engineering can assess your home to determine the extent of any settlement or foundation failure problems and provide a repair design that will restore the property.

Signs of Trouble

Outside your house, do you see:

Cracks in foundation walls?

Gaps in bricks, doors or windows?

Gaps between fireplace & house?

Sagging roof line?

Inside your house, do you see:

Cracks in walls & ceilings?

Doors that stick?

Gaps between walls & ceiling?

Nails popping out of the drywall?

Door or window frames out of plumb?

Floors cracked or not level?

Gaps between walls and floors?

Repair Process

Step One: Foundation Asessment

CG will visit the building in question and complete a full assessment of the foundation condition. Our experienced engineers will respect your privacy and be careful to work around your landscaping and pets as much as possible. It is important to understand that some investigation may require an in depth look inside your attic, crawl space and behind/around landscaping. We will complete a gas level survey to determine the amount of settlement. We will also determine if it makes sense for you to consult with a geotechnical engineer to analyze soil conditions for repair.

Step Two: Recommend Repair Options

An engineer from CG Engineering will meet with you to discuss our findings and suggest a repair solution. Common repair solutions for foundation settlement include push piers, pin piles and helical anchors. Each unique situation calls for a custom solution, which may include a combination of methods. Our engineers will be sure you feel comfortable with the chosen repair method before moving forward.

Step Three: Develop a Site Plan

In order to proceed with a repair design, CG Engineering will need a site plan for your property. If you already have a site plan for your property, we may be able to use it. If you do not have a site plan we will create one.

Step Four: Design and Permitting

Our engineers will design a repair solution for your property and submit the design documents to your local jurisdiction for permit approval. CG’s engineers have experience working with most local jurisdictions and will see to it that your permit is processed efficiently.

Step Five: Contractor Selection and Construction

We will provide you with the approved repair drawings, which can be used to obtain contractor bids. You can select the contractor of your choice to make the repairs. CG Engineering will provide construction support and make an engineer available to answer contractor and homeowner questions as the repair is being constructed.

Homeowner FAQs

Why is my foundation settling?

There are multiple causes of foundation settlement issues. One common problem is settlement of soils below the foundations. Poor site drainage can also contribute to foundation movement. Another cause can be construction on uncontrolled fill. Improperly compacted fill will compress under building footings causing cracking in foundation walls. If you have noticed any signs of foundation trouble on your building or home, we recommend that you have a structural engineer assess the issues.

Why should I work directly with an engineer?

When you work with CG Engineering you can be assured that your home is being analyzed by a licensed professional engineer and we act as an owner’s advocate. We analyze your structure to determine the correct number and location of piles required to stabilize your foundation. Once we’ve developed a repair solution, we provide you with construction-ready documents that you can use to get a permit and contractor bids, giving you the freedom to choose who does the work on your home, with the confidence that the repair was designed by a licensed professional.

What are some common solutions for foundation repair?

Common solutions include stabilizing the foundation with pipe piles, helical anchors or push piers. Our structural engineers have extensive experience in residential foundation repair, so you can be assured your repairs will be engineered to stand the test of time. We can work with your chosen contractor and help with permitting.

How long does the design process take?

Project time frames can vary widely and are subject to many external factors. The major factors involved in determining the timeline for design of a project are the size of project and the involvement of other design professionals. For most foundation projects, we need a survey and geotechnical study to be complete before we can begin. We will do our best to work with your schedule and meet your needs. Engaging with an engineer early in the process is a good idea. We can keep tabs on the design process and be more prepared to start your project when it has reached the appropriate phase. Sometimes, we can make recommendations early on that will save time or money as your project is designed or constructed. After design is complete, you will likely need to permit your project through the local building department. CG can assist you with that as well.

How do you estimate project cost?

Each project is unique, so we take the time to carefully predict the amount of hours your project will take, and provide you with a project-specific estimate and proposal for our services. Depending on your preference, we can provide our services on an hourly fee or fixed fee basis. Sometimes, conditions are revealed throughout the demolition or construction process that require additional engineering time. If this happens we will provide a new estimate as an addendum and discuss these changes with you before proceeding. 

How long does it take to get a permit?

Every jurisdiction will have a different timeline for processing permits. We find that a typical time frame is between three to twelve weeks, but it is highly dependent on the current workload of the permitting department in your jurisdiction at the time of the project. Some counties, such as King County, will take much longer. Our engineers are experienced with most local jurisdictions and can advise you on typical time frames for permitting your project at the time it starts.

Learning Center

We believe that educated decisions are the best decisions. That’s why we developed our Homeowner Learning Center. The Learning Center is full of articles about structural and civil engineering topics that affect homeowners. You can get a basic understanding about what to expect when embarking on projects like foundation repair and slope stabilization, and learn how to determine when you need (or don’t need) an engineer for your project.
