DIY – How to Fix Cracks Around Window Frames

Inspection and Preparation
- Assess the severity and type of crack.
- Clean debris or loose material using a scraper or utility knife.
Apply Joint Compound or Spackle
- For hairline and minor vertical cracks, use lightweight spackle.
- Apply drywall joint compound or mud for larger cracks (horizontal, diagonal, stair-step).
Reinforcement
- This is needed for larger or recurring cracks. Embed fiberglass drywall tape over the initial layer of joint compound. You get additional strength. It also provides flexibility to help prevent recurring cracks.
Sanding and Finishing
- Sand the dried compound smoothly using medium-fine sandpaper (120 to 220 grit).
- Apply additional layers as needed, sanding each coat until flush with the surrounding surface.
Priming and Painting
- Apply a primer coat. Primers help the next layer of paint stay put and not peel.
- Paint with matching interior paint and feathering edges for seamless blending.

Recommended Products and Pros and Cons

Spackle:

Pros: Spackle is easy to use. It dries quickly. Use it to fix hairline cracks. It is also good for fixing minor vertical cracks.
Cons: Less structural strength; not suitable for wide cracks.

Joint Compound:

Pros: A strong and durable repair. It is great for larger cracks and embedding tape.
Cons: You will need to sand it down. It is not a one-done fix but needs sanding and multiple applications. Give it plenty of time to dry.

Fiberglass Drywall Tape:

Pros: Adds flexibility and strength, reducing chances of crack recurrence.
Cons: Slightly visible texture if not applied smoothly; requires careful sanding.

What to do Before Foundation Repair

Avoid repairing extensive structural cracks (horizontal, diagonal, stair-step) before foundation repair, as these issues might recur, wasting effort and resources.

What to do After Foundation Repair

You have gotten your foundation repaired. Now is the time to make these repairs:

Horizontal, diagonal, stair-step cracks: Thoroughly repair with joint compound and fiberglass tape.
Repaint and Finish: Ensure all repairs blend seamlessly with existing walls for a restored aesthetic appearance.
