7 Common Signs It’s Time to Replace Your Siding
Many homeowners don’t realize their siding is failing until visible damage appears—or worse, hidden moisture has already compromised the structure beneath. Being proactive can help you avoid costly repairs and increase your home’s value and efficiency.
Here are the most common signs it’s time to replace your siding:
Cracks, Warping, or Loose Panels
Over time, siding materials can crack, warp, or pull away from the house due to temperature fluctuations, aging, or storm impact. These gaps can allow water, insects, and air to enter—compromising your home’s protection.
Fading, Peeling, or Chalky Surfaces
Excessive sun exposure causes color fading, chalkiness, or peeling on painted surfaces. If your siding no longer holds paint or has lost its vibrancy, it may be too old to protect your home effectively—and dragging down your curb appeal.
Rising Energy Bills or Drafty Walls
Poor insulation and air infiltration are common with older or damaged siding. If your HVAC system is working harder than usual, or rooms feel drafty, your siding may be allowing heat loss in winter and heat gain in summer.
Water Stains, Mold, or Mildew
Dark spots, bubbling paint, or mold growth—especially near seams or joints—can signal trapped moisture behind the siding. Left unchecked, this can lead to rot, wood damage, and even interior drywall issues.
Storm or Hail Damage
High winds, hail, or flying debris can dent, crack, or dislodge siding panels. Even if the damage seems minor, it can weaken the structural integrity and void manufacturer warranties if not addressed quickly.
Aging Siding (15–25+ Years Old)
Most siding systems—especially vinyl or aluminum—have a typical lifespan of 20 to 30 years. If your home’s exterior is nearing that age, it’s wise to have it inspected, even if no major issues are visible yet.
Frequent Repairs or Maintenance Needs
If you’re constantly repainting, resealing, or patching your siding, it may be more cost-effective to invest in a full replacement. New siding materials require far less upkeep and come with long-term warranties.

Siding Service Testimonials
"Sean at DNS is our go to guy. They have done our siding, roof, gutters and gutter screens. We have recommended them to children, friends and neighbors who had these same jobs, plus windows done. Everyone remarks about the good care Sean and Jeff take care of them. You will want to recommend them too. Their team does excellent work on schedule. And they do a great job cleaning up afterwards. After they finished the roof, I didn't even find a stray nail in the grass!"
- John B.
"I had excellent service from DNS on both houses I had. They replaced all of the windows, gutters, soffits. leaf guards, and siding on my last house. On my current house I had them do my gutters with leaf guards. Sean and Jeff are very congenial and professional. Their workers are prompt, do excellent work, and clean up after themselves. I highly recommend them for your home improvements. They do great work and stand by their work."
- Lois P.
"I have used DNS many times, they did my roof, soffits, siding and windows and there is a reason I keep hiring them. They do great work and are reasonably priced and get the work done in a timely manner, but the main reason I continue to give them my business are the people of DNS. From the first contact Sean who is very personable and great to work with to the project manager Jeff, who is also a great guy and so easy to work with. I feel like I'm doing business with friends who I know I can trust and who are going to make every effort to provide me with great products and better yet great customer service."
