"Timber did a great job on our house. We had the initial obstacle of the first contractor we hired being unable to complete the job. This is how we came across Timber. He picked up where the other company left off, repairing unsatisfactory work done by the first contractor. His workmanship showed when he had to come up with some creative solutions using the materials available to him. He was a great communicator and completed the job to our satisfaction, within the timeframe we agreed upon, and for a very fair price."

"A soft wall due to improperly installed gutter by some other entity or homeowner caused water to constantly leak into the wall from the exterior roofline. This soft wall grow moldy and become riddled with pests/bugs. The contractor identified the potential issues, agreed to explore and open the walls and discuss the conditions, made sound recommendations for repair and did exactly what was noted in the repair (replaced a load bearing exterior wall, fixed the sill plate, completed the roof, shingles etc. and closed up the walls on the inside with insulation and sheet rock.). The work was timely, well done, the workers were clean as they did the job and kept the rest of the property clean. The manager of the job David Apel was and is an excellent communicator with phone/email/text and photos of processes and progress. I am going to use this company in my own investment endeavors on other properties and projects given the level of finished work, the timing and especially the level of detailed communication."

"We recently had our foyer completely transformed by Glenn and his crew, and I truly can’t say enough good things about the experience. From start to finish, the professionalism, kindness, and customer service were exceptional. What stood out most was that there was never any pushback, every idea or question was met with “yes, we can do that,” and Glenn always approached the project with patience, confidence, and genuine care. He was incredibly accurate with the project timeline, kept the workspace clean and organized every day, and was very conscientious about working in our home. His crew was professional, respectful, and hardworking throughout the entire process. Most importantly, the final result absolutely brought my vision to life. Glenn truly made my dream foyer a reality. The craftsmanship and attention to detail are beautiful, and you can tell he is extremely talented, knowledgeable, and takes pride in his work. We are beyond happy with the outcome, highly recommend!"

"Worked closely with me from beginning to end explained everything step by step"
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.
