    Guys were polite and their equipment looked good. I asked them, when they were doing the neighbors house to come and give me a quote as well. The site boss guy took my info and number but that was the last of it.(they were on the street for another 2 days taking up all the parking) They didn't even have the respect or professionalism to follow up with a quote.

    We chose Siderman to replace our siding, soffit and eavestroughes. John and his crew did such good work. They were knowledgeable, courteous, patient answering all our questions and respectful of the property. The end result was amazing! Would highly recommend!

    We had been wanting to replace our eaves troughs for a long time and we are so happy we decided to use Siderman Inc. Our first initial consult with their Sales Manager Greg made use feel comfortable in moving forward. They got back to us with a quote in exceptional time. Throughout the entire process they provided us with great communication and updates about when our install would be done. The crew that worked at our house were professional, friendly and instilled confidence in us with their workmanship. We were thrilled with the end product and would not hesitate to recommend Siderman Inc. Job Well Done Thank You

    Siderman was professional and great to work with. They showed up on time and did some of the best caulking I’ve ever seen. They did both around the windows as well as inside the house.

    Siderman replaced our evestroughs on the scheduled day. Cleaned up after themselves. New evestroughs look great. Job well done.

    Mike, this means a lot! We really appreciate this recommendation. Our crews take pride in doing the job right and always treating people well. Thank you for trusting Siderman with your project!

  • 5 out of 5Chad Livingstone4 months ago

    Our original evestroughs (only 15 yrs) were leaking in the corners, bending, and the down spouts were falling off. The original window caulking was poorly installed by the builder. We called in Siderman, and they delivered! Professional, timely, dedicated, friendly service. The crew was engaged, showed great attention to detail and took pride in their work. The old adage of you get what you pay for rings true. If you’re like us and in need of new eves and window sealant, call this company - you will be pleased. They are pros, highly recommended, and we are committed customers going forward.

The latest post from this business

Posted by Siderman Inc. to their own Google profile 3 weeks ago. Their words, not ours.

We like to call this the Batcave. All black. Striking. Bold. We upgraded this home with LP SmartSide board and batten siding. This siding is durable and gives a classic look while standing up to the harshest Canadian weather. Affordable and high performing, LP SmartSide is a clear stand-out! Our project features more than just siding. We installed matching soffit, fascia, and seamless eavestrough. Every part is critical to the home's protection and curb appeal. Curious about LP SmartSide for your house? We would be more than happy to talk to you about it!May 8, 2026Learn more
