- Conduct a thorough inspection of your property. Look for cracks, slopping floors, bowed walls and other evidence of existing foundation problems. Repair any damage.
- Find the source of your foundation problems. Foundations can weaken over time due to excessive moisture, expanding and contracting soil, and foliage growing too close to the structure. A foundation repair expert can determine what is causing the deterioration and correct it.
- Bolt your house. House bolting will increase your home’s stability, which can help minimize damage during an earthquake.
- Strengthen cripple walls. A cripple wall is the wall between the foundation and the first floor. These are the walls that receive the force of a quake. Install braces to strengthen these walls and prevent them from shifting during an earthquake.

Checklist for Diagnosing Foundation Problems
By Shawn Kyles
Early identification and repair of foundation problems can save you money by preventing more extensive damage and, in worst case scenarios, building collapse.
There are many factors that contribute to foundation failure, some visible and some not. Any foundation inspection should take into consideration movement history, environmental conditions, evidence of cracking and other physical manifestations of problems, as well as soil composition.
Here is a checklist for diagnosing foundation problems:
-
Uneven or sloping floors - one of the most common indicators of foundation problems.
-
Wall cracks. When cracks are wider at the top than bottom, it is usually a sign of foundation settlement. Exterior wall cracks that run diagonally along joints can also indicate problems.
-
Wall separation. Walls that are separating from windows, doors, garage doors, floors and ceilings are often evidence of foundation problems.
-
Wall bulging. Any masonry walls that bulge above the ground are dangerous and could result in structural failure.
-
Wall rotation. Settling can cause walls to rotate outward as the structure sinks.
-
Nail Popping: Nails can pop out of sheetrock or gypsum walls when there is a foundation settlement program.
-
Floor and foundation cracks.
-
Doors and windows that don’t open properly.
-
Weak Soil. A foundation can sink when it is built on weak soil.
-
Leaning chimneys.
-
Poor Soil Compaction. Many houses are built using fill soils. If the soil isn’t properly compacted, it can cause structure settlement.
-
Excessive Soil Moisture. Typically caused by poor drainage and water leaks, moisture can soften soil. Settlement damage occurs when the soil can no longer support the weight of the structure.
- Soil Consolidation. The weight of a structure can cause additional soil compression and settlement after the house has been built.
Also look out for:
-
Poor drainage and leaking roofs – causes water puddles to form around the house weakening the soil.
-
Large trees and shrubs growing near the structure – roots will draw moisture from the soil beneath the foundation.
-
Roads, streets and driveways that expand in the heat and push against foundation walls.
Diagnosing foundation problems can require help from an expert to really understand what is causing the situation and how to fix it. If you have any doubts or concerns about your foundation, contact a specialist and ask for an inspection. Any foundation issues should be handled quickly to avoid more severe problems.

JulianConstruction.com: ‘California’s Most Trusted Contractor’
by Shawn Kyles
Last week when I returned home there was a flyer in my door with the above statement, “California’s Most Trusted Contractor,” by a construction company that was looking for business. Among their list of approximately 40 specialties, (yes, I did say 40) they listed Bolting and Retrofitting so it caught my eye. At Julian Construction, Inc. we are experts in Foundation work, including House Bolting, and Earthquake Retrofitting, which includes Bracing Cripple Walls, and Anchor Bolts. We also will replace a foundation as needed, and we can complete a foundation repair to the existing stem wall and footing.
So as I reviewed the flyer, I noted that they did not list a California Contractor License Number on their flyer. Julian Construction, Inc. has a license and its number is 788526. If we send a mailing out, or place a door hanger at your home, we have our number on it. So as a consumer, if you see no license number you should be concerned, and do further investigation, as this is a red flag. Also as a consumer you should note the license number itself, our number 788… is 10 years plus old, a license that starts with say 876… would be around about 4 years, 918…would be only two years old and so on. This lets you know if the company has experience or is new to the business of construction.
So I turned the flyer over to look for the address, none to be found. Our address is 2900 W. Jefferson Blvd., Los Angeles, CA 90018. This is where our office and yard is. Some contractors use a PO Box, a garage or a small office. The concern here is if they have been in business long, or possibly if they are just paper contractors. So as a consumer, drive by the place of business and ask does this look like a construction company? Check for a license and verify the number, make sure they have been around a while, and remember verify your contractor’s location and license number.
If you have a foundation issue involving a broken or cracked slab, or are in need of house bolting, seismic retrofitting, or floor and house leveling, foundation repair or replacement, make sure you select a truly reputable contractor. By law, every piece of promotion they send out should have their license number. Pick someone who has been around for a while, and who has a yard you can visit.
Those are some of the things you can check to find a reputable company.
The fact is, that for the majority of people the home represents the greatest part of a family’s net worth (though that value has taken a hit in recent years). Most earthquake probability studies indicate that much of this net worth may be in danger if the home is not retrofitted properly. The most optimum thing you can do as the homeowner is obtain a better understanding of foundation problems and processes so that you can ask appropriate questions and select the contractor that will perform the best job for you. Most foundation repair contractors will offer a foundation inspection, so you can find out the status of your home and its foundation and find greater peace of mind.

JulianConstruction.com: How to Prevent Foundation Damage from Water
By Shawn Kyles
Water is essential to life, and in most cases is probably viewed as helpful or benign to us.
But rainwater, sprinkler water, and water from broken plumbing can cause significant damage to a home’s foundation. Even though initial signs of water damage may seem insignificant, any evidence of water problems should be thoroughly investigated to prevent the foundation from weakening.
Plumbing should be regularly checked for leaks, along with washing machine hoses and water heaters. One way to find out if there are any plumbing issues, is to take a water meter reading and then turn off all faucets and any appliances that use water. Don’t flush toilets for an hour. Then, re-check the meter to see if the amount of water used has increased. If so, that indicates that you have a plumbing leak that could then cause damage to the foundation. You can also purchase water alarms with built-in moisture sensors, and install them near water-using appliances, and under sinks and toilets.
Also keep your roof free of debris and regularly clean gutters and downspouts. When rainwater can’t pass through a clogged gutter, it can flow down walls to the ground, where it can seep into the home’s foundation. Examine your home’s exterior walls for cracks or holes where rain can seep in, and have them sealed. This includes places where plumbing or wiring enter or exit the building.
Make sure any exterior windows and doors, particularly in the basement, are well sealed and close properly. If you find any windows or doors that don’t open and shut correctly, your foundation may already be damaged and should immediately be inspected by an experienced foundation repair expert.
When water seeps into the soil underneath a foundation, it can cause the soil to expand and lift the foundation, resulting in foundation cracks. When the soil dries, the foundation will settle. Constant expansion and contraction will increase and worsen structural damage. Water can also create foundation cracks and make any existing fissures larger. Other problems resulting from water entering a home include moisture-induced mildew and mold.
Early identification and repair of foundation problems can save you money by preventing more extensive damage and, in worst case scenarios, building collapse. There are many factors that contribute to foundation failure, some visible and some not. Any foundation inspection should take into consideration movement history, environmental conditions, evidence of cracking and other physical manifestations of problems, as well as soil composition.
Studies show that seemingly benign water causes more structural damage to homes than any other hazard. If you have drainage problems or suspect foundation problems may already exist, have your home looked at by an experienced foundation repair expert. Quickly resolving water leakage or drainage problems can prevent costly foundation repairs or replacement down the road.

JulianConstruction.com: Preventing Indoor Mold Problems
By Shawn Kyles
Mold is a type of fungus that travels through the air. When it lands on something that contains moisture, the spores will multiply. When it propagates indoors, it can create serious health problems, including allergies, asthma attacks and pneumonia. Mold can be detected visually or, in some cases, by smell. There are also air and surface tests that can be conducted to determine if mold is present in the environment. After the mold has been found, it needs to be scrubbed off with warm water, detergent and/or bleach. Don’t forget to dry the area after it has been cleaned to prevent the mold from returning. Then, the source of the moisture needs to be identified so it can be eradicated.
There are many ways that the growth of mold on interior walls, surfaces and building materials can also be prevented.
Begin by inspecting any drainage systems, including gutters and downspouts. Look for standing puddles of water, which is an indicator of improper drainage. Remove any debris that has accumulated in the drains, and make repairs as needed. Also inspect doors, windows, and exterior light fixtures for leaks that can cause water to enter your home.
Check to see that your roof is in good repair and keep it properly maintained. Call a qualified roofing company to ensure there are no leaks and for help in fixing any problems. Also inspect your plumbing and make any necessary repairs. This includes preventing or stopping leakage from sinks, toilets and washing machines. Make sure there are no foundation cracks or other damage that can result in water seepage. A foundation repair expert can conduct a thorough inspection of your home to detect any existing or potential problems that could lead to mold growth.
Whenever possible, use mold-resistant materials in basements and avoid materials that facilitate mold growth.
Here are some additional steps to take following a water leak or flooding:
-
Locate where the water has entered your home or building
-
Stop any more water from coming in to the structure
-
Get rid of any water that has accumulated
-
Remove any objects that have gotten wet, including carpeting
-
Remove the lower and upper portions of a walls, including trim
-
Dry any wet areas with fans or heaters
Besides mold, rainwater, sprinkler water, and water from broken plumbing can cause significant damage to a home’s foundation. Even though initial signs of water damage may seem insignificant, any evidence of water problems should be thoroughly investigated to prevent the foundation from weakening. When water seeps into the soil underneath a foundation, it can cause the soil to expand and lift the foundation, resulting in foundation cracks. When the soil dries, the foundation will settle. Constant expansion and contraction will increase and worsen structural damage. Water can also create foundation cracks and make any existing fissures larger.
Studies show that seemingly benign water causes more structural damage to homes than any other hazard. If you have drainage problems or suspect foundation problems may already exist, have your home looked at by an experienced foundation repair expert. Quickly resolving water leakage or drainage problems can prevent costly foundation repairs or replacement down the road.
Many homes have mold. It is the extent of the mold growth that is often the problem. A company that specializes in mold testing and remediation can answer your questions regarding and will usually conduct a free inspection of your property if you are concerned about mold issues. They can also give you good advice on how to eliminate any mold problems.
Types of Home Foundations
- Inadequate construction
- Poor soil compaction
- Poor drainage
- Leaking roofs
- Concrete shrinkage
- Expansive soil
Julian Construction Says Caissons Can Help Support Homes Built on Expansive Soil
Julian Construction Gives Top Five Reasons Why Foundations Fail
Adverse Soil Conditions – A foundations will start to weaken if the soil it is built on expands or contracts. Expansion can occur from too much water, and will lift the building. Contraction occurs from dry conditions, and can result in the soiling pulling away from the foundation
