Concrete Cracks

Concrete frequently cracks no matter how well the contractor has done his job. Despite concrete unmatched surface durability, it is susceptible to the damage associated with annual freeze/thaw cycles. Some concrete cracks are no problem, but other cracks can be a problem and allow moisture to come up through the concrete slab and damage the flooring and perhaps some furnishings. Identifying the potential risks of concrete cracking is most often an issue when you're trying to sell or buy a home. Cracks in the concrete of your foundation or other slabs can unnecessarily reduce the value of your home. On the other hand, if you're a buyer, the last thing you want to do is buy a home without realizing there's several thousand extra dollars of work coming down the line in just a few years or even months.

Home Inspectors
For your own peace of mind, you'll want to ensure the home is of sound structural integrity before you buy it. This situation is tailor-made for a home inspector. Contact a reputable home inspector and pay for a report about the severity of the cracks in the concrete. If he says the cracks are acceptable, then you can relax. But, take some pictures and keep the report just in case they get worse since a builder must warranty a house for latent defects for 10 years. And, if the inspector recommends they should be fixed, show the report to your builder. If he refuses to do anything, tell him you will be filing a complaint with the State License Board with the report.

Cracks in Concrete Flooring
Sometimes cracks occur in your concrete subflooring unrelated to your foundation or the general structure of your home. Often, these cracks are noticed when the floor above the concrete slab becomes damaged by the uneven concrete. Usually the damage of both floors is caused by the presence of water. You'll first need to locate the source of this water or moisture problem and fix it first. Then, you'll most likely need to remove the old flooring, seal the concrete, and install new flooring.

Sometimes, concrete cracking can occur separately from the presence of moisture, although water almost always finds these cracks eventually. Homes with above average drainage in their yard will divert water away from the home and can delay any damage to cracks in their concrete subflooring, almost indefinitely.
