Contractors in Delaware performing construction and remodeling work must obtain a business license from the Division of Revenue.

John R Kosko currently holds license S5-0008472 (Licensed Architect), which was Inactive when we last checked.

Delaware does not require contractors to pass a licensing exam, we advise homeowners to ask for multiple references when vetting a contractor to perform work on their homes.

Contractors in Delaware must carry an active workers' compensation insurance policy.

Contractors in Delaware are not required to obtain a surety bond. Non-Resident Contractors are required to obtain a bond equal to six percent (6%) of the contract amount for all single contracts/subcontracts exceeding $20,000 or when the aggregate of two or more contracts/subcontracts in a calendar year total $20,000 or more.

Delaware does not run a financial or criminal background check on contractors prior to licensing so there is more responsibility on the consumer to do their homework before making a final decision.

The BuildZoom score is based on a number of factors including the contractor's license status, insurance status, verified work history, standing with local consumer interest groups, verified reviews from other BuildZoom users and self-reported feedback from the contractor.

When it comes to major construction work or even minor alterations to your home, hiring the wrong contractor could result in incomplete or defective work. You may even find yourself dealing with huge liability claims. BuildZoom does the homework for you and helps you hire the right contractor.
