Customer Testimonials

Customer testimonials are Winstal’s biggest source of pride, and most of our business is through referral.

For over 60 years, home improvement contractor Winstal has provided high quality replacement windows, doors, and vinyl siding across the South Shore, Cape Cod and Southeastern part of Massachusetts. And our customers have provided great testimonials for our work during that time. Since the beginning, our mission has been to beautify our customers’ homes and treat them as our own. We pride ourselves on our work, because we know that you pride yourself on your home. Customer testimonials make our work worthwhile. Here’s what some of our great customers have had to say about us:


“Many thanks for the timeliness and great quality of your work! We are very, very pleased with everything, the doors, the gutters and the bulkhead! We will be contacting you in the future for other jobs, and want you to feel free to give our names and number as references for potential customers.”

Bill & Virginia | South Weymouth, Massachusetts


“I have to say that you were one of the most reliable, honest, and flexible vendors with whom I have ever worked. I am happy to provide a reference for you at anytime.”

Robert Penta, Saint Agnes School | Arlington, Massachusetts


“Thank you, thank you, thank you. In an era when quality, craftsmanship and perfection have been pushed to the side in favor of a faster turnaround, cheap labor and higher profit margins, Winstal is all about the customer, which is why we keep coming back. After two home renovations, we would be honored to have Winstal use us as a reference anytime. Furthermore, if we do purchase a third home, Winstal will be our first call. Thanks again.”

Robert & Diane | Whitman, Massachusetts


“Thank you for the great work on our new front doors- main door and storm door!  Bill was very accommodating, quick, clean and friendly to work with.  Additionally, after I had a change of heart on what I ordered and Bill installed, Bill worked with me quickly to find alternative solutions to fit my ever changing wants.  It looks great!  Thank you.”

Nicole | Scituate, Massachusetts


“Thank you so much for the wonderful job that you did on my front porch windows! I appreciate your good work, your kindness, and your attention to the details, cleanup, etc. The next time I need any window(s), or can give a referral, it will be with you! Thanks again and have a great rest of summer!”

Judy | Quincy, Massachusetts


“The work done at our home was amazing – it certainly exceeded our expectations. The quality & pride your company provides is very hard to come by in this fast-paced world. We will enjoy the new deck for many years. We also will recommend you and hope to see you again! Thank you.”

Michael & Maribella | Avon, Massachusetts


“Awesome job! Winstal Company sided the porch at the rear of our home with Certainteed vinyl siding, as well as repairing a lot of the mistakes made on the home by the original installer. They also replaced the picture window on the front of our home.  We are extremely happy with all the work that was done and will be happy to provide a reference.”

Kevin & Patti | Norton, Massachusetts


“Your professionalism, and dedication to see a job completed to the fullest, is appreciated. You went the extra mile, which is rare and hard to find. Thank you for providing the various services to complete my roof and chimney. Your professionalism in handling the job, job site removal and clean up was to the tens. It’s been a pleasure, and I thank you.”

Paula | North Weymouth, Massachusetts


“Thank you for such a wonderful job. We were so thrilled when we saw the final results. It was actually perfect. Again, it was such a pleasure doing business with you and your family.”

Richard & Dorothy | Plymouth, Massachusetts


“We want you to know that we are thoroughly pleased with all the work you did, and particularly appreciate the little “extras” done for us – a new doorbell light, our address mounted in aluminum, etc. We love the look of our new windows, inside and out. Please feel free to have any prospective customer call us for a reference. We will definitely keep you in mind for any future home improvements we might need.”

Sam & Marylyn | Weymouth, Massachusetts
