BASEMENT FOUNDATION & CRAWL SPACE REPAIRS
Do you have cracks in your floors or along your basement or crawlspace walls? If so, then you probably have foundation problems. Since your foundation is the main support system for your entire home or building, problems with that foundation can impact every room.
Cracking and bowing in your foundation walls can lead to all kinds of moisture and water seepage in your home. That moisture can carry bacteria and mold, causing health problems for your family, or staff and customers. Higher energy bills also come with foundation issues. Cracks let air in and out of your home causing your air conditioner and heater to work harder and longer than they should, costing you money. Make an investment now to preserve the value of your home and ensure future savings.

What Causes Foundation Damage?
For the vast majority of most foundation damage, water intrusion is the primary culprit. Variations in moisture cause components of the soil to swell or shrink, leading to movement beneath your foundation. Your property may be more susceptible to foundation damage if:
✅ Your foundation was built on expansive clay
✅ Your foundation was built on improperly compacted fill soils
✅ Your foundation has poor drainage around its exterior
✅ Your home is in an area with extreme seasonal changes
✅ Your home experienced a plumbing leak beneath the foundation
✅ Tree roots are growing too close to your home
✅ An act of nature (earthquake, flood or drought) compromised the foundation structure
✅ Your homes is positioned above underground rivers and streams, which is very common on Long Island
What are the Signs of Foundation Damage?
All foundations will settle with time, but problems arise when settlement is uneven or extreme. Here are the common signs of foundation stress:
