Pat sat with me and went over everything from start to finish. There was absolutely no pressure and no scare tactics. Gonsana started and finished the day they said they would. Everything was left in perfect shape and thoroughly cleaned. The new roof is beautiful! I highly recommend using Gonsana. They’re honest, fair and respectful.
Gonsana is the most professional contracting company I’ve ever worked with. Gonsana did my siding and extended my back roof to fix the ventilation issues. They also rewrapped my windows & doors making them look 10X better. They are very reasonable priced & Jeanette was very helpful and a pleasure to work with. Bolivar did superior work.
Gonsana was professional from the initial estimate to job completion. They communicated well with our maintenance staff detailing job progress. Jeanette is very knowledgeable and coordinated very well with our office. Bolivar, Patricio and all other workers were very knowledgeable, friendly and did a great job. We highly recommend Gonsana.
The Gonsana crew worked tirelessly on my project with total professionalism. They were very clean from start to finish. I can’t thank Gonsana enough for the fabulous job they did on my roof. I have recommended Gonsana to all of my friends, neighbors & family and look forward contracting Gonsana again for future projects. Thank you Gonsana.
Patricio came out and gave me an excellent estimate for the work that was needed. Patricio came back with another man a few days later to start repairs. They completed the work in one day and I’m extremely satisfied and impressed with the level of work and professionalism that was conducted with both Patricio and the Gonsana Construction Team.
Very good company, detail oriented, professional job at a fair price. Had a roof removed and a new one installed. They were on time and left everything clean. Jeanette keeps you informed from start to finish. Excellent customer service. Pleased with my new roof. Highly recommend. I will definitely use them again. Thanks again
Just had 2 skylights replaced in my home by Gonsana. I would highly recommend their services. Jeanette was very helpful and informative. Great job from start to finish, all great workers, especially Patricio “Foreman”. It was very nice to work with you. Thank you
We were affected by Hurricane Sandy and Gonsana came in and worked with our insurance company to help us get the most for our money. Jeanette was gracious and listened to me when I wanted to fall apart. The guys came on site and worked quickly and never left a mess. Thank you so much and yes, we will be doing business in the future.
We’re extremely happy with the outcome of this project. Had 6 different companies come out but Gonsana was by far the best price wise! Jammyl & Jeannette were very thorough with handling quotes and scheduling. Extremely professional and the crew cleaned up well after the project had been completed. A+! We highly recommend them!
Jammyl was very thorough and knowledgeable with my roofing estimate. They ripped the two layers of shingles off, replaced the wood and completed the roof. It was dark when they finished so Jammyl came back the next day to ensure everything was cleaned up. I ended up having them replace my window & roof vent pipes. Highly recommend!!
Gonsana has been a blessing to Vineyard in repairing out steeple. Yes, we would recommend them. Their workmanship was superb.
I contacted Gonsana to replace an old leaky skylight on my roof. Jeanette was extremely knowledgeable and went beyond the call of duty. Patricio gave me a detailed estimate of the work and cost. They were prompt, efficient, professional and the quality of work was exceptional. I give Gonsana an A+ rating and recommend them to all.
There is no need for a lot of words about Gonsana. All that is needed is “THE BEST” work, price ethics and “JAMMYL” also “THE BEST” a no nonsense person. I will surely deal with them again...
Been working with Pat and Jeanette for many years on dozens of roof repairs and replacements. They complete the work at the lowest possible pricing and always in a timeline that meets or exceeds our expectations. They are very easy to work with and handle permits / inspections quickly. I would recommend them for any roofing repairs.
Had a roof job after the storm. No leaks. Had a new outer door put in. Looks like it was made for my home. Left area cleaner than before. Gentlemen workers.
Jamyl, Bolivar and the crew did a great job at my home. They called ahead of time, came on time, did quality work, cleaned up the yard and then called to make sure that I was satisfied with the workmanship. I highly recommend them.
Gonsana gave us a quote for replacing the entire roof as well as repairing an area of out chimney. That also included a deluxe skylight. The quote amount was $10,600. We got them as a referral from a friend of ours.
The Gonsana crew was very professional and precise in their work. The Gonsana Team worked flawlessly. I would “HIGHLY” recommend Gonsana Construction. The best construction company I have found in years.
Bolivar did an amazing job finding a leak in my roof that others had missed over the last 20 years. He was extraordinarily professional to deal with & explained how he was going to solve my problem. I would not hesitate to use him again & I’m sorry I did not meet him until now. I recommend him wholeheartedly.
Very pleased with this company’s professionalism . They work very hard, are neat & clean, the office manager Jeanette answered all my questions in a timely manner. The job needed to match an old color & they came almost perfect to the match. Back Siding & Insulation were done to perfection. Highly recommend them. A 10 Star Rating!
I found this company through a friend. Jammyl came over for the estimate & sent a price over right away. It was competitive & I felt comfortable moving forward. The guys worked long & hard to finish on time. My roof looks great & my yard is cleaner than it was before they started. They also capped my fascia & around my windows. Job well done.
Gonsana did my roof after an exhausted search with other companies. They were superior to the top other 5 companies in the area. I got a fair price, perfect workmanship & reliability. Jeanette was great with all permits & paperwork. I recommend Gonsana Construction without hesitation. They know what they are doing!
I’m thrilled with GONSANA. They responded quickly, Jammyl was very easy to speak with & understood exactly what I needed. The work was done quickly, accurately & all workers clean & friendly. They protected my property & cleaned up like they were never there. SERIOUSLY, don’t hesitate to call them. They’re respectful, talented & honest.
My wife and I are very satisfied with the professionalism & workmanship of Gonsana Construction, from start to finish. Bolivar is very knowledgeable, trust worthy & his recommendations were very well taken in the project completion. Jeanette, is very pleasant and provided excellent customer service with all questions asked.
I had my roof replaced 6 1/2 years ago by a less than ethical roofer. A dear family friend (MS. Donelan) suggested I contact Jammyl. He arrived quickly to give me an estimate & work schedule. The crew arrived on time and completed the work. All trash had been removed. Gonsana is my new roofing company. Excellent Job Gonsana!! Thank You!!
Gonsana did a complete roof replacement. They were meticulous in the details & craftsmanship. They were promptly on time & cleaned up at the end of every work day. Bolivar was happy to answer questions we had throughout the construction process. We’re extremely pleased & satisfied with our new roof. Highly recommend Gonsana!
