Underpinning Repair
Building Foundation Problems - Underpinning
An underpinning problem occurs when a structure is settling/sinking to the point where
repairs are needed to shore up the foundation.
Project Costs of an Underpinning Repair Project
Costs are rough estimates for the project in Chicago. For suburban or rural areas,
the price should be 25-30% less. Please note these tips when reviewing the sales quote:
- Materials charge. Make sure you are given credit for materials not used. If the
quote is for a 50 foot pier, and the contractor installs a 30 foot pier, you should get
a credit for the unused materials.
- Labor charge. Make sure you get a decent estimate as to the hours required for the
job. If you are quoted for a four week project, and the contractor completes it in one
week .. there is something wrong.
- Take photos or videotape the installation. Some contractors take shortcuts
during the installation of these piers - a visual record can help solve disputes.
