How Do You Know When It’s Time to Replace Your Siding? (and how much it costs)

Your home’s siding isn’t just about curb appeal—it’s your first line of defense against Northeast weather. It keeps out rain, wind, pests, and extreme temperatures, protecting everything inside your home. But over time, siding wears down and stops doing its job effectively.

At BMG Exteriors, we’ve been helping homeowners across Philadelphia, the suburbs, South Jersey, and Delaware replace and upgrade their siding for over 30 years. Here’s how to tell when your siding has reached the end of its life—and what you can expect if it’s time for a replacement.

Top Signs It’s Time to Replace Your Siding

1. Cracks, Warping, or Loose Panels

If your siding is cracking, bulging, or falling off, its structural integrity is compromised. Gaps and loose panels allow water, pests, and cold air inside your walls.

Pro Tip: If you see bubbling or bulging, that often means there’s moisture trapped behind the siding—a sign you may already have water damage.

2. Rot or Soft Spots

If you have wood or composite siding, rot can spread quickly, especially around windows, corners, and foundation lines. Soft spots usually indicate hidden water damage behind the panels, which needs attention fast.

3. Faded or Peeling Paint

Vinyl siding shouldn’t need painting, but severe fading or chalkiness means your siding has lost its UV protection and is wearing out. For homes with wood trim or fascia boards, peeling paint often points to moisture intrusion behind the siding.

4. Mold, Mildew, or Water Stains

If you see streaking, green mold, or black mildew, water isn’t draining properly. Over time, trapped moisture leads to rot, structural damage, and interior leaks if left untreated.

5. Rising Energy Bills

Old or poorly installed siding usually means poor insulation. If your heating or cooling bills are climbing even though your usage hasn’t changed, your siding—or lack of house wrap—could be the culprit.

6. Insect Damage or Holes

Termites, carpenter ants, and even woodpeckers will exploit weakened siding. Holes and gaps allow pests inside your walls, causing bigger issues if not addressed.

How Much Does New Siding Cost?

Siding replacement costs depend on your home’s size, material choice, and custom trim work. Here’s a general pricing guide:
