What to Caulk on the Exterior of a New Construction Home | Caulking Tips for a Weatherproof Finish
What happens here
Begin by understanding that this new construction exterior project involves addressing suboptimal prior caulking work, likely performed during cold winter conditions, which can compromise sealant effectiveness. It is critical to choose a high-performance, flexible caulk, such as 'Big Stretch,' which is suitable for exterior use on various materials like Hardie board or cement board siding. This type of caulk is designed to accommodate material expansion and contraction without cracking or separating. Avoid using cheap sealants, as they often lead to poor adhesion, separation, and ultimately, ineffective weatherproofing, requiring premature re-application. A quality caulk will ensure longevity and superior performance against drafts and moisture.
Goal: Gain an understanding of the project's unique challenges, particularly regarding previous caulking done in adverse conditions, and select a high-quality, flexible caulk to ensure durable weatherproofing.
