Everything You Need to Know About Lowering Your Basement

 

Are you contemplating ways to enhance your living space without the hassle of moving or the expense of constructing an addition? VMB Group is here to enlighten you about one of the most effective methods to achieve this: lowering your basement.This comprehensive guide will walk you through the ins and outs of this process, helping you make an informed decision.

When To Lower Your Basement?

Deciding whether to lower your basement can be a big decision. Here are a few key points to help you determine if it’s the right time for this project:

  1. You Need More Living Space: If your house feels cramped and you’re in need of additional room, but extending outwards or upwards isn’t possible or desired, lowering your basement can create the extra space you need.
  2. Improve Home Value: If you’re looking to increase the value of your property before selling, adding usable living space in the basement can be a wise investment.
  3. Use Your Basement Space: When your current basement is primarily a storage area, crawl space, or otherwise underutilized, transforming it into a livable area can enhance your home’s functionality.
  4. Fix Foundation Issues: If you already need to repair foundation problems, it’s an opportune time to consider lowering your basement as part of the process. This can address two needs in one project.
  5. Upgrade for Better Comfort: If you want to improve your home’s insulation, waterproofing, or overall comfort, lowering the basement can be done alongside these upgrades, ensuring a drier, warmer, and more comfortable living environment.

The Advantages of Basement Lowering:

  1. Increased Living Space: By lowering your basement, you essentially gain an additional floor of usable space. This can be transformed into anything from extra bedrooms, a home office, a gym, or an entertainment area—without altering your home’s footprint.
  2. Improved Structural Integrity: This process often involves reinforcing your home’s foundation. Strengthening the foundation not only supports the basement lowering but can also correct and prevent future structural issues, contributing to the longevity of your property.
  3. Better Energy Efficiency: During the process, you’ll have the opportunity to add modern insulation and waterproofing solutions. This can lead to a more energy-efficient home with reduced heating and cooling costs, as well as a more comfortable living environment free of dampness and drafts.
  4. Customizable Options: Lowering your basement allows for a level of creativity and customization that can be more constrained in other parts of your home. Whether you want to add unique features, such as a home theater, or incorporate design elements that match your personal style, the possibilities are expansive.
  5. Solves Low Ceiling Problems: Older homes with basements that were not designed for modern living standards can benefit greatly. No more ducking down or feeling cramped; enjoy full-height ceilings and a more open, airy space.

When To Lower Your Basement?

Two primary techniques are employed in basement lowering: underpinning and bench pinning.

  • Underpinning involves excavating below the existing footing to pour new footings at a reduced depth, followed by reconstructing the wall sections. This method is meticulous and pricier but results in a stronger structure and addresses foundation issues.
  • Bench Pinning, a quicker and more cost-effective technique, doesn’t require new footings. The process involves digging to the new depth and constructing a bench along the perimeter walls, which reduces overall basement size but is less intrusive to the foundation.
