Homeowner FAQs
Crawl space insulation vs encapsulation – which is better?
Crawl space insulation is typically ill-advised on its own. When insulation gets damp or wet, it stays wet. Dampness and mold that is able to grow in your crawlspace will move throughout your home. We recommend a setup that includes a double-sealed vapor barrier as well as a dehumidifier and sufficient drainage system.
My concrete seems to have moved up during the winter months, is this a problem?
If your concrete has shifted up during the winter months, it is most likely heaved from the frozen dirt below the concrete. This is normal, and usually the concrete will return to normal once the ground thaws. If it doesn’t return to its normal position in the spring, you may want to have one of our experts take a look to determine if a permanent solution is necessary.
What causes a floor joist to sag?
Excess moisture in floor joist, overspanned joist supports, and excess load above joist can all cause joists to sag.
Can you repair cracked concrete after going through concrete leveling?
Yes. In fact, we recommend that our TerraFirma Concrete Leveling customers seal the cracks and joints of their newly lifted concrete with our NexusPro solution, as it will help protect their concrete for many years to come.
My concrete seems to have settled over the winter. What should I do?
Your concrete most likely didn’t settle, but instead the adjacent concrete slabs heave upwards, due to the frozen dirt below. There is nothing that can be done, but wait for the ground to thaw and the concrete to return to its original position. If the concrete doesn’t return to its normal position in the spring, you may want to have one of our experts take a look to determine if a permanent solution is necessary.
