Why is my apron sinking when the house is only three years old?
High-volume building means utility trenches and street cuts get backfilled quickly, and that fill keeps consolidating for years. The concrete above it follows the dirt down. Replacing the apron on properly compacted base is usually the durable fix; lifting a young apron often just buys time.
Can you widen my driveway or add a third-car strip?
Yes, this is one of the most requested jobs in Princeton, because builder drives rarely fit two trucks and never fit three. We sawcut, dowel into the existing slab, and pour to match its elevation. Expect a visible color difference at first; it softens as the new concrete weathers.
What does a new driveway cost here?
Tear-out and replacement generally starts around $8 to $14 per square foot depending on size, demo, access, and thickness. Widenings are quoted from the actual layout. We price after walking the site, never a number over the phone we can't stand behind.
Should I go through the builder's warranty instead?
If the home is inside its warranty window and the failure is clearly settlement of the builder's work, yes, start there, and we will say so at the assessment. Where the warranty answer is a patch you are not happy with, or the window has closed, that is where we come in.
How long before we can park on it?
Foot traffic is typically fine the next day, passenger vehicles at about a week, and heavy trucks or trailers only after the slab has gained most of its strength, usually several weeks. We put the specific dates for your pour in writing.
Do you handle the permit and the city apron rules?
Yes. Work in the right-of-way, including the apron, carries its own requirements, and we manage that scope as part of the job rather than leaving it with you.
