This is a very common question, and can be the most difficult one to answer. The length of construction time can vary greatly depending on the size and scope of work to be completed. Here are some general estimates for "middle of the road" sized projects:

Kitchen and Bath Remodel

An average kitchen and bathroom remodel usually takes about two months.

Home Addition

Depending on square footage, a simple living room addition or 4 season porch takes about two to three months. This can vary greatly depending on if you're thinking of adding a full basement underneath the addition.

Basement Finishing

Depending on the level of finish and size of your basement, it's best to expect your remodel to take about four weeks. If you're putting in a bathroom as well, it will be more in the six week range.

Screen Porch & Deck Addition

When additng a new screen porch and deck, you can count on this type of project lasting three to six weeks.
