One of the biggest mistakes is underestimating the budget. Always include a contingency of at least 15 to 20 percent for unexpected issues like water damage, asbestos, or old plumbing problems found once walls are opened.
Avoid choosing the cheapest tradie without checking licences and reviews, as poor workmanship in wet areas leads to costly water damage down the track. Do not move plumbing unnecessarily, as this adds significant cost for little visual benefit.
Avoid over-capitalising for your property type and neighbourhood. Skimping on waterproofing is a critical error that causes long-term structural damage.
Working with a reputable company like Mitroteam Projects means all waterproofing and compliance work is done correctly from the start, reducing the risk of expensive problems later on.
