Home Additions questions, answered
How long does a home addition take?
Most additions run 12 to 20 weeks from demolition to final walkthrough, depending on size, foundation work, and township permitting timelines.
Do you handle permits and engineering?
Yes. We manage structural engineering, township permits, and inspections from start to finish so you never chase paperwork.
Can we live in the home during construction?
In most cases yes. We wall off the work zone, protect finished areas, and keep utilities live wherever the scope allows.
