"Working with Tom and James, Brian, Nick, and Tom was a pleasure! Tom came to my house, masked (due to COVID19) and sold me the window.His price was very reasonable and within the realms of other quotations I had received. The time frame he set for the installation was within days of the actual work being done. His workmen were fast, (window was installed in 2 hrs!) extremely courteous, and Clean!!!! I am VERY pleased with my new window! I would Highly recommend this company."

"excellent.Response  when first contacted from Angie's List was immediate. Our downspouts are all clogged and gutters, they showed us what they could do and gave us several prices and we decided to go for their gutter topper as well.  We signed a contract and they gave us an idea of when they could start. As anyone knows that PA has gotten almost2-3 daily downpours and thunderstorms.  Their office called  that they would be here as soon as possible.

"When I first contacted the company they did not return my call.   I got several estimates from other companies and then decided to try Summit again.   This time the owner (Gino) returned my call and explained that he had gotten my first message but his phone had broken and he had lost my number.   He promptly came out out to the house and gave me a very reasonable estimate for the work.  He sent a contract which I signed and returned, and which also indicated the work would begin within 1 -2 weeks of the signing date (8/12/13).   Two weeks later he indicated he would begin the work that week but never showed up because it rained.  He said he would return Tuesday of the following week.   He did not show up but sent an email that Thursday saying he had other emergency work that needed to be done and that he would start the next week.  He did not show up the following week at all and did not respond to my emails and calls.  He finally emailed on 9/19/13 apologizing for lack of response due to losing his Ipad.   He explained that he had again run into emergency water damage/insurance issues and was short on manpower, but would begin the next week.  Once again he did not show up that week and emailed me on 9/27/13 saying he would start the following week.   He and several workers finally showed up the first week of October (six weeks after I had returned the signed contract).   They worked for a day or two and then did not return for another week.   The rest of the work was completed over the next two weeks by a single worker (not Gino) who was VERY professional and VERY skilled.  
Ultimately, I was very pleased with the work that was done and I was quite satisfied with the price.  It was, however, a very frustrating experience in terms of not knowing when they would show up or when the work would be completed.  I definitely felt like he was "fitting me in" and that the job was not a priority for him.   I understand that emergencies can come up, that weather can make it difficult to work, and that there can be staffing issues.   I just wish Gino had been more responsive and kept me in the loop.  Not knowing what was happening was the hardest part.
So, I would definitely recommend Summit Peak for price and quality of work, but I would be hesitant to hire them again because of the responsiveness issues.

"The provider requested OK from Choice Warranty and he was denied. It rained last night and rain came into my home. It could have been avoided if Choice had just approved what I requested. Now, the damage will be greater than necessary. I blame Choice home warranty for my home damage. Now it will cost mote than a simple tarp could have prevented until I could get money to repair roof. The provider was great and tried his best to get something done to my roof but Choice Warranty was horrible and no help. They get a "zero" from me"
