Dealing with this company in a siding project after the hail last May 2017 is the equal to buying a car and realizing you got a lemon. Project started in October 2017 and finally ended the end of October 2018. During this time period of one year, I had to point to what needed fixed, complained about their crews leaving cigarette buds all over my yard, on the gas meter, and leaving insulation loose in the backyard, not to mention all the crooked cuts, exposed areas, the gutters that they hung more than once, falling to the ground.
Very frustrating! They received a lot of money for me to have to point multiple times over the year what needs to be done and continuously "fixed." I can go on and one about the headaches I have had to deal with, but enough said. On a positive note their roofing crew did a fantastic job, doing the main house and the garage in one day, but I would still never use this company again. It was really ridiculous and time consuming on my end.

Do NOT use this company! I worked there for three weeks Jan 2019. Still haven't received a dime. Owner is nice but doesn't know how to run a company. Lacks organization, leadership, money, customer service and the ability to make decisions. Always putting out fires and desperate for jobs to pay previous bills. Check BBB and stop in to visit location. One look at her desk will show you how your work will be. Disaster!

These guys were awesome. I called to get a new security door, energy efficient windows and a security light. They were kind, prompt and had competitive prices. I'd use them again in the future.

From start to finish the installation crew were great. Always informing us of the way they remove and install new windows. All though there were 3 upper windows were a challenge, they still kept working and finished as the day came to the end. Great supervision and crew.

We were very happy from start to finish. Price was very fair and the products turned out very nice. Matt Gravina was our sales-rep. I would recommend them for any home improvement needs!

My family used this company in the past and had nothing but great reviews but now that I used them I had nothin but trouble. The estimate and price was not bad. But after they have you hooked you just a number. I constantly had to call for updates and force them to move on to the next step. I waited over a month past my agreed time frame with barley a sorry and no money back. If finding a good value is all that's important to you then this is a good option but if your time, or customer service is of importance then I recommend someone else.
