GREAT STUFF PRO Pestblock Insulating Foam Sealant Review: Is it Worth the Money?

Are you battling unwanted pests and drafts in your home? The GREAT STUFF PRO 11073754 Pestblock Insulating Foam Sealant promises to seal those gaps and cracks, keeping critters and cold air out. This professional-grade sealant aims to provide long-lasting protection against insects, rodents, and energy loss, offering a more effective solution than standard caulking or weather stripping. But does it live up to the hype?

In this comprehensive review, we'll delve into the features, benefits, and drawbacks of the GREAT STUFF PRO Pestblock, helping you decide if it's the right choice for your home improvement needs. We’ll compare it to other urethane adhesives and insulating foams on the market, and offer practical advice for using it effectively.

Key Features

The GREAT STUFF PRO Pestblock Insulating Foam Sealant boasts several key features designed to provide superior performance:

  • Pest-Blocking Formula: Specifically formulated to prevent insects and rodents from entering your home through cracks and crevices.
  • Insulating Properties: Provides an airtight seal, reducing energy loss and improving home comfort.
  • Professional-Grade Quality: Offers a more durable and long-lasting seal compared to standard foam sealants.
  • 20 fl. oz. Can: Provides ample sealant for tackling multiple projects.
  • Urethane Adhesive: Expands to fill gaps and creates a strong bond with various surfaces, including wood, concrete, and metal.

Pros

The GREAT STUFF PRO Pestblock offers several advantages for homeowners and professionals alike:

  • Excellent Pest Deterrent: The infused insecticide effectively deters pests, preventing them from chewing through the foam. This is a significant advantage over standard insulating foams.
  • Superior Insulation: Provides a tight, airtight seal, reducing drafts and improving energy efficiency. You'll likely see a noticeable difference in your energy bills.
  • Durable and Long-Lasting: The professional-grade formula is designed to withstand harsh conditions and resist cracking or crumbling over time. This ensures a long-term solution for sealing gaps and cracks.
  • Easy Application (with proper gun): When used with a professional foam dispensing gun, the application is controlled and precise, minimizing waste and mess.
  • Versatile Use: Suitable for a wide range of applications, including sealing around pipes, filling gaps in walls, and insulating windows and doors.

Cons

While the GREAT STUFF PRO Pestblock offers many benefits, it also has a few drawbacks to consider:

  • Requires a Professional Gun: Unlike canned foams with attached straws, this product requires a separate foam dispensing gun for application. This adds to the overall cost and may be a barrier for some users.
  • Can be Messy: Like all expanding foams, it can be messy to work with if not applied carefully. Over-application can lead to excess foam that needs to be trimmed, resulting in waste.
  • Higher Price Point: Compared to standard insulating foams and caulking, the GREAT STUFF PRO Pestblock is more expensive.

Who Should Buy

The GREAT STUFF PRO Pestblock Insulating Foam Sealant is ideal for:

  • Homeowners battling pest infestations: If you're constantly dealing with insects or rodents entering your home, this sealant can provide a significant improvement.
  • Individuals looking to improve energy efficiency: Sealing air leaks is a crucial step in reducing energy consumption and lowering utility bills. The Pestblock provides a highly effective solution for insulating your home.
  • Construction professionals and contractors: The professional-grade formula and durable seal make it a reliable choice for building projects and renovations. Its pest-blocking properties add extra value to the finished product.
However, those on a tight budget or needing a quick, one-time fix might consider cheaper alternatives like standard canned foam or caulking. But remember, those options won't offer the same level of pest protection or long-term durability.

Conclusion

The GREAT STUFF PRO 11073754 Pestblock Insulating Foam Sealant is a premium product that delivers on its promises. While the initial investment is higher due to the need for a dispensing gun, the long-term benefits of pest control, superior insulation, and durability make it a worthwhile investment, particularly for those serious about protecting their homes and reducing energy costs. Consider alternatives like Dow Great Stuff Gaps and Cracks if budget is a primary concern, but remember the Pestblock offers superior pest control. Ultimately, its performance justifies the price for those seeking a professional-grade solution. Use a high-quality foam cleaner to clean the application gun after use to prolong its life.

So, I have mixed feelings. On one hand, it definitely helps with precision, which is great because eye drops are pricey. On the other hand, the material is kind of hard and isn't the most comfortable thing to press against your eye socket. It’s better than nothing, but I wish the edges were softer or padded. 3/5 stars for me.

tbh its kind of a toy. it burns the edges of the toast before the middle is even warm. i ended up returning it and getting a bigger one for a few bucks more.

They're okay, just smaller than I thought they'd be based on the photos. Idk if I'd buy them again but they do the job.

A very practical purchase for our guest playard. The fabric is breathable and fits securely, which was my main concern for safety.

These are great for beginners. They are lightweight and the fabric is breathable so your hands don't get too sweaty. They might not hold up for years, but they do the job well for the price point.
