Can You Put Siding Over Stucco? What You Need to Know to Avoid Issues

No longer loving the look of that old stucco siding, but not keen on spending thousands to remove it before residing? You can put siding over existing stucco, and with proper prep work and planning, you can save money over removing the old stucco first.

Can You Install Siding Over Stucco?

Yes, it’s possible to install siding over stucco, and with the cost of removing stucco averaging $2,000, it’s usually more cost-effective to cover the stucco rather than tear it down for a fresh start. You’ll need to hire a siding professional to assess your home for existing damage and prepare the exterior walls first, though.

Things to Consider Before Covering Stucco With Siding

When it’s time to install new siding, there are a few important things to consider if you don’t plan on removing that old stucco first.

Existing Leaks or Damage

One issue with stucco is that it readily absorbs water and can crack over time, leading to leaking behind the material. Installing siding over your stucco will mean trapping any moisture, which can lead to mold growth. You should always have a professional assess your stucco for damage before proceeding with the new siding installation. You may need to contact a siding repair company near you to carry out repairs before it’s safe to install siding over the stucco.

Surface Preparation

You’ll need a structurally sound, even base to attach your new siding. Most siding companies will install pressure-treated furring strips over the stucco and then attach the new siding to those strips. They may also install a vapor barrier or insulation to help with moisture and home energy efficiency.

Stucco Finish

Those furring strips need to be level, otherwise your new siding will look uneven. Stucco with a rough finish may require some additional prep to smooth it out to allow the furring strips to sit flat against the exterior walls.

Added Wall Thickness

Adding siding over your stucco will add to your wall thickness, which can leave windows and doors set back from the exterior wall. Your professional may need to extend those wall openings to create a clean look and proper drainage.

What Types of Siding Can You Install Over Stucco?

Fiber cement siding is a popular choice for covering stucco, but you can choose any siding style and material as long as your professional prepares the exterior walls properly. You can use the siding costs below to choose one that fits into your budget. Note that the required prep work can add 5% to 10% to your total.

Is It a Good Idea to Install Siding Over Stucco?

Installing siding over stucco is perfectly safe if a professional does the work for you. A pro will set up proper drainage to avoid moisture build-up and mold growth between the materials, and they’ll install furring strips to create a perfectly flat surface to install the new siding.

Even if you have experience installing siding, it’s best to avoid DIYing the project. With a pro doing the work, you’ll have boosted curb appeal, a lower installation cost than if you paid to remove the stucco first, and, most importantly, no added risk of moisture problems.
