How long does underpinning (basement lowering) take?

The act of lowering your basement, also known as underpinning, is a major undertaking. It involves a whole host of measures such as floor drains, insulation, waterproofing, wall partitions and the reinforcement of your home’s foundation. You may choose to add a basement walkout. As a result, the cost involved is completely dependent on the amount and type of work being done.

The deeper you want to dig your basement, the more work will be required to complete the project

Before you even start the whole process, it’s important to get drawings and permits handled. Have a structural engineer take care of the drawings and permits, which could take two weeks or longer. The expense of the permits is dependent on the linear footage of the job which includes your drain and plumbing permits too.

Properly Insured Underpinning Contractor Required

You’ll need to make certain you have a contractor who is properly licensed and insured for underpinning projects because this work isn’t covered by general liability insurance. Check out a copy of the insurance certificate and ensure it includes the following details:

at least $2 million in liability along with the contractor name and address.

Finally, when selecting a contractor for underpinning work, request references and review a portfolio of completed projects.

While work takes place on the underpinning process, there can be the odd curve ball that happens, especially with older homes. Such problems can add some time to a project. Most underpinning jobs are usually completed within two to four weeks, but that doesn’t include all the finishing work required or the walk-out if selected.

Aspects of an Underpinning Project may include;

  • Specific engineering details that arise
  • Water lines or meters may have to be moved or installed
  • Electric panels new or relocated
  • HVAC systems that need relocation
  • Basement stairs may require a rebuild or an extension
  • Landry room or other addition inside the new space
  • Walk-out required

Exterior Waterproofing is Required

It’s necessary to provide outside waterproofing because it protects the underpinning project. You may also select a sump pump system so you can remove storm water surge but this is something we would recommend during the evaluation and quotation process.

It isn’t easy to forecast the precise time it will take to complete an underpinning job. To get more information on basement lowering, please contact us directly by phone or email.
