I had a great experience with A&J Williams contracting. My home had sagging floor joist which made my home uneven in certain spots. I contacted A&J and came out to see what he could do to fix the issue. He got me a quote in a timely manner. Fixed the issue in 1 day and now my home doesn't sag, my floor is now even. I would recommend and use A&J contracting in the future again.

Austin and his crew did some concrete work on my driveway. The job came out great! He was very responsive and showed up every day when he said he would. Not sure why you would go with anyone else for a project big or small!

They have done a great job each time they have done work on our home. Their employees are always on time, professional and work hard to get the job done in a timely manner. They made sure I loved the work before finishing and were more than willing to stay if I wasn’t satisfied. I highly recommend this company for roofing, general repair / construction needs.

We had them install siding on our home and we absolutely love the work that they did. Extremely friendly and professional. We couldn't have asked for a better result and very fair priced for the quality that we received. 100% recommend this company to all my friends and family.

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.
