Thebco offers homeowners two main brands to consider for their siding replacement: Mastic and Everlast.



ASCEND composite cladding is the world’s first siding engineered with combination of glass-reinforced polymer and graphite-infused polystyrene.

Everlast is unlike any other siding you’ve considered, and the moment you see it, you’ll know why. Solid construction means the planks don’t bend or bow, and align perfectly against the outer walls of your home. Distinctive trim choices from the Everlast Trim Collection are made from the same polymeric material to ensure a look that perfectly blends with and naturally fits your Everlast cladding – providing you with one beautiful finish.

For generations, low-maintenance vinyl siding from Mastic has been the number-one choice among builders, remodelers and homeowners.
Professionals and homeowners prefer low-maintenance home siding made of vinyl or polymer over wood, fiber cement, brick or stucco options. And it’s easy to see why Mastic is a favorite choice for vinyl siding.
Mastic products feature the beauty of freshly painted or stained wood. Whether you choose lap siding or vertical siding, you get a beautiful exterior product that’s built to last. Every home siding style is beautiful, durable and easy to maintain — which means you’ll spend more time enjoying your home, and less time working on it.
