"I recently had my roof replaced by Cox Roofing LLC in , Toledo Ohio and I couldn't be happier with the results. The project was actually completed about a month ago, but I got busy and completely forgot to leave a review! Now that I have a moment, I wanted to make sure they get the credit they deserve. Their team was professional, efficient, and the quality of the work is top-notch. If you?re in the Toledo Ohio and need roofing services, I highly recommend them!"

"Bill from WBI was the first to contact us and the first to give us a quote on the insulating of the attic and crawl spaces of our old farmhouse. The price was very fair for the professional quality of work we received. Bill is a very honest, competent, hard-working professional. He got the job done very quickly, and we are beyond pleased with the work he did for us. We can't say enough good things about WBI, and we highly recommend them!"
