1. What exactly is caulking?

Caulking is a flexible sealant that fills gaps and cracks between different materials. Think of it like a superglue for your home’s joints, preventing water, air, and even insects from sneaking through.

2. Where does caulking need to be done?

Caulking plays a vital role in various areas of your home:

  • Around windows and doors: Sealing these gaps prevents drafts and helps maintain energy efficiency.
  • Bathrooms and kitchens: Caulking around showers, bathtubs, sinks, and countertops creates a watertight barrier, preventing mould growth.
  • Baseboards: Filling gaps between baseboards and walls prevents drafts and keeps critters out.
  • Exterior siding: Sealing gaps between siding panels protects your home from water intrusion.

3. How often should I recaulk?

Caulking isn’t a one-time fix. Over time, it can crack, shrink, or lose its flexibility due to weather exposure. Generally, it’s recommended to inspect your caulking every year and recaulk as needed.

4. What type of caulk should I use?

There are different types of caulk for different applications. Here’s a quick breakdown:

  • Silicone caulk: Great for kitchens, bathrooms, and other areas prone to moisture.
  • Acrylic caulk: Flexible and paintable, ideal for trim, baseboards, and some exterior applications.
  • Polyurethane caulk: Strong and weather-resistant, best for exterior gaps exposed to the elements.

5. Can I caulk myself, or should I hire a professional?

Caulking DIY projects are definitely possible, especially for small areas. However, for larger jobs, intricate areas, or if you’re unsure about technique or choosing the right caulk, hiring a professional caulking service ensures a clean, long-lasting application.

Bonus Tip: Before caulking, ensure the surface is clean and dry. For a flawless finish, use painter’s tape to create a neat line and remove it after smoothing the caulk.
