It’s possible to DIY your siding replacement, but that’s only recommended if your home has no underlying damage. Mold and rot are best left to siding contractors, as they can ensure all the damage is removed from the home. If you’re not practiced in home siding installation, it’s recommended you hire a siding contractor, whether the job is a small repair or an entire siding replacement. Small installation mistakes can create costly fixes. Professionals can examine your siding, make recommendations based on your specific circumstance, and give you an estimate. For peace of mind, hiring an experienced, local siding contractor is the way to go.
