Craig can't stress enough how important it is to get an independent weathertightness report on your home carried out prior to selling, especially a plaster home. For around $700-$800, you can have a detailed report highlighting any possible weathertightness issue areas around your home. Don't leave it to a prospective buyer to find issues that could mean a delayed sales process. Knowing any issues 3-6 months out before going on the market means you have time to remediate any concerns. The report provides a clear picture to a business like 445 as to what the issues are meaning they can then pull together a scope of work, focused on your priorities.
