Why I Believe in Supporting Jacks for Crawl Space

As a homeowner, I have learned the importance of properly maintaining my crawl space. This often overlooked area of the house is crucial to the overall health and stability of my home. One key aspect of crawl space maintenance is ensuring proper support through the use of jacks.

Firstly, supporting jacks are necessary to prevent structural damage. The weight of the house above can cause the floor joists in the crawl space to sag over time. This can lead to uneven floors, cracks in walls and ceilings, and even potential collapse. By using jacks to lift and level the floor joists, this issue can be prevented and the structural integrity of the house can be maintained.

Secondly, supporting jacks help prevent moisture issues in the crawl space. A sagging floor can create gaps between the foundation and floor joists, allowing for moisture to seep in. This can lead to mold growth, wood rot, and other issues that can affect not only the crawl space but also the rest of the house. By stabilizing the floor with jacks, these gaps are closed off and moisture is less likely to enter.

In addition, using supporting jacks for crawl spaces can also improve energy

My Buying Guide on ‘Support Jacks For Crawl Space’

Are you planning to add extra support to your crawl space? If yes, then investing in support jacks for crawl space is the right decision. As a homeowner who has gone through the process of choosing and installing support jacks for my own crawl space, I understand the importance of making an informed decision. In this buying guide, I will share my first-hand experience and provide you with all the necessary information to help you choose the best support jacks for your crawl space.

1. Know Your Crawl Space Requirements

The first step in buying support jacks for your crawl space is to understand its requirements. Measure the height of your crawl space and determine how many support jacks you need based on its size and weight-bearing capacity. It is recommended to have at least one support jack per every 8 feet of the crawl space perimeter.

2. Consider the Material

Support jacks are available in different materials such as wood, steel, and aluminum. Each material has its own advantages and disadvantages. Wood is affordable but can rot over time. Steel is strong but can rust if not properly maintained. Aluminum is lightweight but may not be suitable for heavy-duty use. Consider your budget and the specific needs of your crawl space before choosing a material.

3. Opt for Adjustable Support Jacks

It is crucial to choose support jacks that are adjustable in height. This will allow you to level out any uneven surfaces in your crawl space and provide customized support according to your needs.

4. Look for Durability

Since support jacks will be holding up the weight of your entire home, it is important to invest in ones that are durable and long-lasting. Look for jacks made from high-quality materials and check for any warranties or guarantees offered by the manufacturer.

5. Consider Installation Process

Some support jacks require professional installation while others can be easily installed by homeowners themselves. If you are not confident in DIY projects, it is best to opt for professional installation services.

6. Read Reviews

Before making a purchase, read reviews from other homeowners who have used the same brand or model of support jacks that you are considering. This will give you an idea about their experiences with the product and help you make an informed decision.

7.Evaluate Cost vs Quality

While it may be tempting to go for cheaper options, remember that quality should not be compromised when it comes to supporting your home’s structure. Invest in high-quality support jacks that may cost more upfront but will save you money in potential repairs or replacements down the line.

In conclusion, choosing the right support jacks for your crawl space requires careful consideration of various factors such as material, durability, adjustability, installation process, and cost vs quality trade-offs. By following this buying guide and doing thorough research, you can ensure that you make a well-informed decision that will provide maximum safety and stability to your home’s foundation.
