Blog / 7 Common Contractor Mistakes in Jobsite Prep (and How to Avoid Them)

December 11, 2025

Jobsite prep is more than just a good habit. It’s non-negotiable for preventing damage. Additionally, it reduces clean up time, improves safety on the job and leaves a creditable, professional impression. Unfortunately, some contractors and crews make mistakes that are easily avoidable- leading to costly delays and repairs. The good news? With smart planning and the right Trimaco products, these mistakes can be easily prevented.

Jobsite Prep Mistakes to Avoid

Even pros can miss steps when prepping a site. Here are the most common jobsite mistakes and how to fix them:

1

Skipping Surface Protection

Why it matters: Floors, counters, and fixtures can get scratched or stained. Fixing damage costs money and time.
How to avoid it: Take time to cover surfaces before work starts. Trimaco has strong floor and surface protection products for any job.

2

Using the wrong tape

Why it matters: The wrong tape can peel paint, leave sticky residue, or fall off.
How to avoid it: Pick tape that matches the surface and job length. Trimaco offers tapes and masking products for every need.

3

Not using Dust Containment

Why it matters: Dust spreads fast, and once it spreads- its hard to clean up.
How to avoid it: Use barriers and zipper doors to keep dust in one area. Trimaco’s E-Z Up® Dust Containment System is quick and easy to set up.

Forgetting about safety

+

Why it matters: Hardwoods are becoming more popular in many homes. However, when using a canvas drop cloth, the surface quickly becomes a slipping hazard.
How to avoid it: Opt for a slip resistant drop cloth, that features a grippy backing that won’t budge on hardwoods.

5

Not wearing PPE

Why it matters: Workers need protective gear to stay safe. Skipping PPE can lead to injuries.
How to avoid it: Stock PPE before starting—like respirators, gloves, and coveralls. Trimaco offers a full line of PPE.

6

Ignoring weather risks
