Common mistakes

• Sealing drainage paths. This can hide the real cause, create rework, or make different quotes impossible to compare.
• Making the seal so thick the lock will not latch. This can hide the real cause, create rework, or make different quotes impossible to compare.
• Covering moisture damage. This can hide the real cause, create rework, or make different quotes impossible to compare.

When professional help makes sense

Stop when the work reaches concealed wiring, plumbing, gas, structure, hazardous materials, unsafe height, or a permit requirement. A narrow professional repair is often cheaper than recovering from a failed DIY attempt.

Ask for a written scope that separates diagnosis, required work, optional upgrades, exclusions, permits, and the conditions that can change price. That makes the work easier to compare and reduces disputes.
