“ At first it was very difficult dealing with my insurance company. They even tried to talk me out of placing a claim. Joe did not accept that response, in fact he took the offense and represented me. At the end of the day I was approved for a full roof replacement and a full siding replacement. Thank you Joe for all your help. I am truly thankful! ”
​Mr. and Mrs. Norton

“ Joe Guzman did a great job helping me restore my home. I had damage from the March windstorms. Joe and his team made sure to help every step of the way. They delivered what they promised. ”
Mr. and Mrs. Bergolis

“ Joe came to my home to inspect the roof for possible damage due to all the storms we have had. He was polite, professional and explained to my wife and I the procedures of replacing our roof if we were indeed in need of one. There was a piece of siding sticking out from the side of my home which he gladly fixed for us. Before fixing the siding, he cleaned out a bird's nest he found where the siding had broken off. He did it without hesitation. Our roof ended up not needing any work done but we would recommend Joe and his company to all of our friends and family and keep him in mind for any future repairs. ”
Mr. and Mrs. Evans

“ Great work, really reasonable price and did the work in one day. Joe always stayed in communication throughout the project for every next step. Clean up after the project was excellent too. Would recommend and hire again for other jobs in the future. ”

This company represents itself very well and the craftsmanship was EXCELLENT! Joe and Amore kept me up to date during the entire project and they were very punctual. I would recommend them and use them again for future projects. Job well Done! Thank you. ”

“ On my first call, Joe never hesitated to see my issues. He immediately set up an appointment over the phone. I was able to go over the gutters problems, and some minor structural with the fascia boards. He and his crew were able to complete the job in a fashion, and professional manner. Joe is geared to hear your issues, and resolve them in a customer-friendly manner. I certainly will recommend Guzman Service Associates. Thank you, Joe, for solving my problem. ”

“ Mr. Guzman gave me a very reasonable repair quote and stuck to it. He performed the work on the day he promised. He took before and after photos of the repair areas so I could see the work performed without getting on the roof. He explained to me that my house would require a total replacement in 2 to 3 years but not just now. I will definitely be getting a quote from GSA Assoc. when that time arrives. ”

“ Joe Guzman is a delight to talk to and receive his highly professional services from! He was very cordial and thorough in his inquiry during his onsite visit for the replacement of our gutter. Despite their busy schedule in a busy season, he was able to come a week later. The job was done very well and they even took our old gutter that was already detached and on the ground! He followed up with photos of the job, because we were not home during the service. The total cost was VERY competitive and even almost HALF of the other companies' estimates we received! I WILL recommend him to anyone else I know that needs gutter work. ”

Joe was also very kind, personable, and professional--commendable character goes a long way. I would recommend GSA Home any of my friends and family, and will definitely use them again in the future. ”

“ My wife and I used GSA to replace our roof when we had some storm damage and we couldn't be happier. We loved the fact that we were in regular communication with the owner Joe who couldn't have been more helpful throughout the entire process. Everything was explained to us perfectly and during each step of the process. The quality and speed of the work was and is amazing and we love our beautiful new roof! We wouldn't hesitate to use GSA home again and have already told many friends and family about them. ”

“ The gutter replacement service was outstanding. Joe and Amore showed my family a very high level of professionalism. I will dare to say that they treated us as their family. Joe explained to me the pros and cons of each gutter option to make the best decision according to our house needs. I will not hesitate to contact them again for any future roof work. ”

“ After doing my research and due diligence with over 30 roofing companies (if not more) it came down to 3. Out of those 3 companies, the only company that truly treat you like family and also keep you updated in every single step of the way is Guzman Service Associates. Joe does a terrific job on keeping you aware of the pros and cons of doing a specific build and his wife Amore is probably the best project manager I've spoken with. Both of them (and the crew that works for them) are very detailed oriented and I never felt rushed on taking a decision. ”

“ Joe came out to look at our job and found a way to fix the problem for about $2150 less than other quotes! He is a dedicated and hardworking family man who will not up-sell or over sell you! His fix solved the problem and saved us time as well as money. I recommend this organization very highly! ”

“ A big Thank You to Guzman Service Associates. They were at my house on the scheduled day and completed all the repairs required. Their prices are also the best in town. I will never use anyone else. I used this company last year on another house after a severe wind storm and they worked closely with my insurance company through every step. The end result was a new roof and also new siding for the entire house! Wow. These are the best people to entrust your home with. ”

“ I am absolutely thrilled with the way they run their business and their work. From their first response to my inquiry to my final review when the work was done, I have absolutely no complaints. They were polite, professional, responsive and knowledgeable about their products and services. I found them to be honest and forthcoming - there was no hard sales push and no annoying schmoozing. They did what they said they were going to do for the price they said they were going to do it, and they were flexible in their scheduling. If you have to have work done or are thinking about having work done, I recommend giving them an opportunity to bid for your project. ”

“ At first, I was a little weary to hire Joe and his company. The reason being is there are so many false companies that hit a neighborhood after any given storm and offer a great deal to fix your roof. I must say I was impressed from start to finish. Joe was very detailed in explaining everything that was going to happen. After everything cleared from the insurance he continues to keep me up to date on the process and what would happen next. I love my roof and I was totally impressed with how thorough they were on cleaning up. I HIGHLY RECOMMEND GUZMAN SERVICE they are very trustworthy. I would refer them to everyone. ”

“ Joe and Amore are an awesome team in their company serving their clients with so much honesty in the business that they do for us. They have the utmost integrity who I come to trust instantly upon meeting for the first time. I was blessed to have been referred to Joe for our principal house this year after the wind storm we had. ”

“ If you recall, one of your crews was installing new gutters on my neighbor's house. I walked over and asked you to take a look at a problem that I was having with a section of the gutter on my property. You came up with a creative solution and a few days later my problem had been solved. After a couple of weeks, I asked you to come back and readjust the slope of my gutter. You arrived that same afternoon! You made some adjustments and now my gutter system is perfect.I would like to thank you again for your lightning fast response to my call. ”
