Highly recommend Cornell Construction LLC for your home building and improvement projects. Brett Cornell and his craftsman/resources just completed a major upgrade to the outside of our house and shop. New siding/trim, new patio, new metal roofs on the patio/2 sides of the shop, new shingles, lighting, and painting. Execution was outstanding and the project was a huge success. We are quite satisfied with the work. Thanks Brett!

Brett did many jobs to help prepare my house for selling. He installed both interior and exterior light fixtures as well as new smoke detectors/carbon monoxide detectors. He also put drawer and cabinet pulls on all my kitchen cabinets, changed all door locks and rekeyed them to all match. Additionally, he repaired shelves in my kitchen cabinets. All this work was completed quickly and competently. As a bonus, Brett went to the hardware store to pick up needed material, saving me considerable time.

I was delighted to find that Brett could do anything and everything I asked of him. He also advised of other contractors to help with more specialized issues. I would rate Brett and Cornell Construction, LLC a 10+ if that was an option on Google.

We are very happy to have worked with Brett and his construction company. We had an unwelcome restoration project of 2 bathrooms and a living room due to water damage. Brett is a great communicator, sets a schedule in advance of the various subcontractors and checks on the work regularly. He pays close attention to detail and ensures that the work is done very well. We will contact Brett for any future projects. We highly recommend him to others.

Brett remodeled our fireplace. He gave us great ideas and executed the plan beautifully. He was always on time, finished the job on schedule, kept us informed, and cleaned up everyday before he left. He made our dull and outdated fireplace the beautiful centerpiece of our home. I would highly recommend him and will hire him for any job in our home.

I’ve used his service multiple times ranging from drainage pipe issues to installing overhead garage racks and have never been disappointed. Great quality of work for reasonable prices.

Only downfall is I always seem to find new projects I want to take on with his help :)

Thanks Cornell Construction for installing the screen door and making it easy on us. I appreciated being able to text with what we were looking for in the door and finding options that were dog proof (meaning that a dog can’t zoomie through it like an all mesh screen).

This is our second job completed and thoroughly enjoy the easiness of doing business and quality work. Key take aways- quick to respond, easy quoting, fair priced, reliable, flexible and trustworthy. There isn’t many people that I trust to be inside my home while no one is there-but Cornell construction is one! I also appreciate the fact that he would work within a budget and transparent with costs too.

Thanks again, I look forward to whatever project comes next!

Cornell Construction put in a new kitchen faucet for us and showed us how to hook up our underground sprinkler system. Brett also advised us on outside lighting and offered to give us an estimate to do it. This Company is very professional and thorough we will be using their services again.

Brett has done numerous jobs for my family. He cannot be recommended high enough. We have never been disapointed and he is as good as gold. Hire him quick before he is to busy.

Bret fixed a leak on my sprinkler system, and took the time to adjust some sprinklers for better efficiency. He is very friendly and a fast worker. Will definitely call him for my next needed repair work.

Brett did an amazing job. We needed some safety rails and grab bars installed. His work looks great and the safety bars are super sturdy. He was quick to respond to our request, provided drawings and a clear estimate, and finished the work on time. I'd recommend him for any remodel or handyman needs.

To hire a roofing contractor, start by researching local companies with good reviews and proper licensing. Request quotes from multiple contractors, verify their insurance and certifications, and ask for references. Always ensure you get a written contract that outlines the scope of work, timeline, and payment terms.

4. How to check if a roofing company is legit?
+-

Check if a roofing company is legit by verifying their business license, insurance, and local certifications. Look for memberships in professional associations, read customer reviews, and ask for recent project references. A legitimate company will be transparent and provide all documentation upon request.

5. How to choose a roofing company?
+-

When choosing a roofing company, consider their experience, customer reviews, warranty offerings, and quality of materials. Make sure they provide clear communication, detailed estimates, and a solid portfolio of completed projects. Local expertise is also a major advantage for understanding regional roofing needs.

6. How do you know if your roofing contractor is ripping you off?
+-

Warning signs that your roofing contractor might be ripping you off include vague contracts, pressure to pay large upfront deposits, lack of proper documentation, and unexplained price increases. Always ask for itemized estimates and written guarantees, and avoid contractors who avoid answering your questions directly.
