Aug 28, 2025

Discover 5 common mistakes that make homeowners waste money on renovations. Learn how to choose a reputable contractor, supervise construction, and save costs effectively.

Renovating a house is a costly and complex process, requiring caution from choosing workers, supervising construction, to signing contracts with contractors. However, many homeowners still make mistakes that lead to unnecessary expenses, or even having to “tear down and redo.”

In this article, NQT Construction will point out common mistakes when renovating a house and how to fix them so you don’t waste money.

1. Paying workers in full upfront – A serious mistake

One of the most common errors is paying all the wages to workers right from the start. In many cases, after receiving full payment, workers abandon the project and disappear, leaving unpredictable consequences.

👉 Solution: Make payments in stages, based on the progress committed in the contract. Only pay in full when the project is completed as required.

2. Workers misusing funds and inflating costs

Many homeowners are taken advantage of by workers who fake documents, inflate material prices, or pocket money intended for purchases. This not only increases costs but also delays the renovation process.

👉 Solution: Always check invoices and receipts. Contact material suppliers directly for verification.

3. Hiring without verifying skills

Many homeowners rely only on advertisements or hire unreliable small-scale services, leading to quickly deteriorating results: cracked floors, peeling walls, broken bathrooms…

👉 Solution: Choose a reputable construction contractor with a clear contract, professional workers, and a warranty commitment.

4. Lack of supervision during construction

Without regular supervision, workers may cut corners, use the wrong materials, or apply incorrect techniques. The result: warped wooden floors, tiles that peel off quickly, and doubled repair costs.

👉 Solution: The homeowner or a trusted representative should be present throughout the construction to ensure progress and quality.

5. Relying only on friends’ recommendations without further checks

Many homeowners, trusting their friends, hire unqualified contractors, resulting in extended timelines, poor quality, and even higher costs than initially estimated.

👉 Solution: Even with referrals, you should do your own research: inspect previous projects, read reviews, request quotes, and demand a transparent contract.
