"Worst experience ever! Jon Dodd caused hundreds of dollars of damage to our house and would never admit to do doing it. I have over 30 pics to document the damages when he worked here. When confronted, he would not tell the truth, ever! Knew he put a shelf in wrong but took a chance and did not mention it. (He did admit it later) The shelf fell and broke $300 in wedding dishes. He is NEVER on time. Denied putting the big scratches in our brand new $800 sink. His paint sprayer was bad and leaking, yet he still tried to use it and wasted over $150 in Kilz and got it all over the floor, tracked it upstairs and never cleaned it up. He broke an antique mirror and denied doing it when he was the only one in our house! A job that we were guaranteed would take 3 days ended up taking over 5 WEEKS because he would not show up even after saying he would be there in text, and denied it until I showed him his own text! Stood us up several times. He is an immature pathological liar that I am convinced does not have the ability to ever tell the truth or admit guilt. His last screw up was installing a cabinet door (FINALLY) and stripping out the screws in the bottom hinge. Then telling me it was installed and ran out and drive away before I found it out. I am filing charges against him for all the damages and to get all the overspray cleaned up on all my furniture that he never covered, including $150 for a new internet/TV modem that barely works now because of the overspray that is now inside it. Jon does not have even the simplest of skills, and causes more harm than good. He can not even chalk without smearing it all over! Do not ever trust him!!"

FAQs for stair railing installation projects in Knapp, WI

Generally, general contractors charge between $50 and $150 hourly, though not every contractor charges by the hour. If charging based on the project, you can expect a markup of 10% to 20% of the construction cost. You can expect to pay between $300 and $500 daily if charged by the day.

General contractors are the ones that coordinate home construction projects. They are in charge of the day-to-day oversight of the subcontractors to ensure that the project is completed on time and to resolve problems as they arise. General contractors:

  • Complete pre-construction planning, both with the customer and crew

  • Provide realistic cost estimates

  • Develop construction timelines

  • Ensure deadlines are met

  • Acquire permits as needed

  • Purchase supplies and materials

Before hiring a general contractor for your home project, it’s a great idea to write down a list of questions to discuss with each prospect. Some example questions to get you started include:

  • Which types of insurance do you carry?

  • Can you provide a list of references?

  • What is the expected timeline for this project?

  • How will my project be supervised?

  • Will you hire subcontractors for the job?

  • What is the best way to communicate changes?

  • Will you obtain all of the required building permits?

While city and state laws vary on general contractor licensing requirements, hiring an unlicensed general contractor could lead to poor quality work, costly future expenses, and potential code violations. Be sure to check our state licensing tool to review the local general contractor guidelines for your area.

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.

Yes, most general contractors require a down payment for project completion. A reasonable down payment for a contractor is 10% to 25% of the total project cost, though that will vary based on project size and location. The down payment helps cover the upfront costs of materials and permits and helps ensure payment for the project at hand.
