Introduction Caulk is a flexible sealant used where planes meet and may move; grout is a rigid filler for joints and hard-edged work. At a change-of-plane, pros usually choose caulk to allow movement and reduce cracking. Grout stays stiff and can crack if the gap flexes. For a DIYer, the key is matching the material […]

Introduction A vapor barrier in a crawl space is a sheet or cap that blocks ground moisture from entering the space. Install it on the dirt floor and along any access routes, and always check the product label or local rules if you’re unsure. Seams should be overlapped and sealed so moisture can’t seep through,

Introduction Thermal bridging happens when heat leaks through studs and framing, creating cold spots and condensation. This article shows simple, practical fixes you can do on a typical wall. You’ll learn how to spot problem areas and choose safe, non-technical approaches. Start by inspecting where framing meets insulation and looking for gaps or compression that

Introduction Spray foam and rigid foam are two insulation options you can install in rim joists to stop drafts. Spray foam expands to fill gaps, while rigid foam provides a solid, flat layer. Check product labels and local rules for where each type is recommended and how it should be installed. Think about fire safety,

Introduction Air sealing stops drafts faster than insulation alone. It blocks the path that cold air uses to move through gaps and cracks. This usually shows up as an immediate improvement once you seal the big leaks. Insulation helps slow heat movement but won’t stop air leaks as effectively. For a durable fix, focus on

Introduction A vapor retarder is a material in walls that slows moisture moving through the wall. Where it goes depends on the wall design and climate, so check the product guidance and local rules. If you’re unsure, use the simplest, approved option and follow the manufacturer’s directions. They can contribute to mold if moisture gets
