These guys were outstanding. They were on time, they were courteous, my wife asked if they could attend to a very small item and they jumped on it no questions asked except to get her approval. They delivered everything they said they would. It was truly a great experience to work with this company. My father was a contractor and this company does it right. I would HIGHLY recommend this company.

Here's what you need to know: You get what you pay for!I think that every bit of the job they performed on my house was a bargain given the attention to detail, hand holding and care provided. It's worth every penny paid when you see the results. They're main interest is making sure you're okay with every step till the final result is achieved. I had the lead contractor ensure that my cable, which I use for my business, was properly working while doing an expert job on my roof. GenEx was recommended to me by a very good friend. Someone who works in the trades and is a pro himself.It lifts me up every day I come home and look at my house and garage. What a great job! THANK YOU ALL!

Exceeded Expectations!

We highly recommend GenEx based on their repair of our home after extensive hail damage including new roof, siding, fascia, soffits, gutters, and windows. They are a well established local contractor owned by hands-on experienced tradesmen (Paul and Dave) that have excellent working relationships with the top local professionals in all required trades. The project manager (Greg) and/or one of the owners was on our job daily monitoring progress, physically envolved, and suggesting creative ideas for improvements. GenEx routinely did more than we expected. The single most important service that they offered was representing us with the the insurance adjuster to make sure that all our damage was discovered and fully covered per the terms of our insurance policy. We are completely satisfied and give GenEx our wholehearted recommendation.
