Exterior Siding FAQs

Siding can be damaged by a variety of factors, including harsh weather conditions, such as wind, hail, and rain, as well as exposure to UV rays and extreme temperatures. Other potential causes of damage include impacts from objects like rocks or tree branches, insect infestations, and poor installation or maintenance.

Cracks, warping, fading, or water damage are just a few of the symptoms that it may be time to replace your siding. Also, if your energy costs are higher than normal or you see a surge in pests near or around your home, this might suggest that your siding is no longer functioning properly.

Re-siding your home can provide numerous benefits, including improved curb appeal, higher energy efficiency, and increased protection from all types of weather. New siding can also increase the value of your property and prevent the need for costly repairs during its lifespan.

That all depends on the condition of your siding. Replacing those pieces may be possible if only a few portions are damaged. However, if your siding is old or shows signs of wear and tear, replacing it all at once may be a better approach. Our experts can evaluate your siding and advise you on the best course of action.

The best siding for your home depends on various factors such as durability, aesthetics, and maintenance requirements. Options like aluminum, fiber cement, wood, and steel are popular choices for their durability, low maintenance, and aesthetic appeal. Consulting with a professional can help you make an informed decision based on your specific needs and preferences.

We had a great experience with the siding that was installed. Right from the start with Valz our sales rep all the way to the installation guys that did the siding, soffits, facia and eaves. They kept us informed about the process and timing of everything. The installers were friendly, kind and helpful. I would highly recommend Custom Aluminum Siding.

When we wanted to update our house with new siding, soffits, facia and eaves we chose Custom Aluminum Siding and Windows. The staff in the showroom are knowledgeable. Our sales rep John answered all our questions and dropped by a couple of times during the project to see if we had any concerns. Our installers Kevin and Steve were great. They also took the time to address any questions or concerns we had as the project progressed. They cleaned up thoroughly at the end of each day. We couldn't be happier with the end result. Thank you to all that worked with us.

It is my pleasure to write this review of the work completed by Custom Aluminum Windows and Siding Ltd. We have had this company to our home twice, first Cawo installed the windows and doors and second Steve and Kevin installed the soffit, facia, eaves trough and window shutters. Before starting either job, all our questions were answered fully so that we understood the process and could manage expectations. In each case the professionalism, tradesman skills and attention to detail are clearly seen in the finished product. They completed the job on time, removed all of the old product and invited us to do a walk around of the completed job before their departure. We are extremely pleased with the results. We have received numerous compliments from neighbours and visitors and have recommended this company again and again. If you want the job done right the first time, with superior product, skilled, knowledgeable, experienced tradesman call this company!
