What Alside ASCEND Composite Cladding Is Covered For
Lifetime limited warranty, transferable — converting to a 50-year prorated warranty for the next homeowner. Includes coverage against hail damage under one inch in diameter.
And our workmanship warranty on top of it
Every siding installation includes a written, transferable 5-year workmanship warranty covering our labor — on top of the manufacturer’s product warranty.

Where Alside ASCEND Composite Cladding Makes Sense
Homeowners who want the fiber-cement look without the weight, dust or repainting cycle.
Siding failures are almost never the siding — they are the water management behind it. We detail the housewrap, flashing and kick-outs first, then hang the product.

How Your Siding Project Runs
- 01
Wall assessment
We check for soft sheathing, previous water intrusion, and how the existing windows and doors are flashed. What we find changes the scope — better to find it now.
- 02
Product & color selection
Large-format samples on your wall, in your light. We mock up trim and accent colors before a single piece is ordered.
- 03
Tear-off & sheathing repair
Old siding comes off, damaged sheathing gets replaced, and the wall gets a proper weather-resistive barrier — not just tarpaper stapled up.
- 04
Flashing & installation
Window and door head flashing, kick-out flashing at every roof-wall intersection, then the cladding itself installed to manufacturer spec so the warranty stays valid.
- 05
Trim out & cleanup
Soffit, fascia, corners, J-channel, caulk lines. Magnet sweep and haul-off. Warranty registered in your name.

I used Top Dog Exteriors for some siding work on my house. I couldn’t be more pleased with the results. They were able to get to me within a week of contacting them. The crew did an amazing job and was able to finish in one day. We have a steep roof which I thought was going to be an issue but they were able to handle it no problem. I will definitely be using them in the future for other projects around the house.

Tyler and his crew came to our rescue after another contractor left us with an unfinished project. They sealed and wrapped our windows which were left exposed by the previous contractor, reset our doors and then did a fantastic job siding our property. The work was meticulous and communication was excellent. Excellent. We intend to use them for another project in the near future.

They did an amazing job. Could’ve cost me a fortune by buying an entire box of siding. But they went the extra mile to find the pieces I needed. Fast and efficient.
