Frequently Asked Questions
Why do I need a permit and inspections to build my deck?
The State of North Carolina requires permit and inspections to ensure safe construction and materials. Also, in the event you decide to sell your home, you can demonstrate to prospective buyers that your deck was properly permitted and passed all code requirements.
Why do I need to install flashing?
When your deck or porch roof is attached to your home, a failure to properly install flashing will allow water to penetrate into your home. Moisture penetration can cause a multitude of problems, including wood rot, deck failure, mold inside your home, and other structural damage to both your home and deck.
If I use a contractor, does the contractor need to be a licensed general contractor?
For most deck projects, a licensed general contractor is not required. However, if the cost of your deck is greater than $30,000, the general contractor must be licensed by the State of North Carolina.
If I need electrical work done, is the electrical contractor required to have a license?
If you hire a contractor to install any electrical device, then the contractor must have a valid North Carolina Electrical license - regardless of the cost of work.
Why do I need to install an electrical receptacle at my deck?
As of Jan. 1, 2009, the National Electrical Code requires at least one receptacle to be mounted above the walking surface of any deck. If one already exists in the required location, then you meet these requirements.
Tips for Hiring a Contractor
Obtain at least three estimates with references.
Check all references.
Before the work begins, make sure you have a written contract and a valid permit.
Most reputable contractors do not require a deposit. However, a reasonable deposit is approximately 20% of the total cost of the project. The remaining balance is paid when the project is completed and has passed final inspections by the Town of Wake Forest Inspections Department.
