Patching Holes in Drywall & Plaster

The Ultimate Handyman can repair any size hole in drywall and plaster, even if your dog can fit in it.

We patch any hole no matter what size, and we promise to remove the dog before we patch it.

Did your plumber go to town on all your walls during a re-piping job, gifting you with plenty of water, air drafts, and bugs streaming from the new holes?


Sorry to give you this news just now, but you should have hired us in the first place. We have plumbers and all the other trades necessary to finish a job properly. The Ultimate Grandma once said: “If you don’t know how to finish it, don’t even start.” We take this advice to heart in all our affairs.

We repair everything from small cracks to gaping holes, including jobs that require special textures, such as acoustical ceilings. We prepare, we protect, we prime, we patch, we paint, and we perform any other related “P”s we may have left off this list.

Why patches show, and it is almost never the patch

A repair that fails visually fails in one of three places, and the hole itself is the easy part.

  1. The texture does not match, so the patch reads as a different surface under raking light

  2. The paint does not match, because paint on a wall has aged and the new coat has not

  3. The joint telegraphs, because the compound was feathered over too narrow an area

A patch that is invisible from three feet and obvious from the doorway in afternoon light has failed. Matching the surface is most of the skill.

Texture matching is a trade of its own

Southern California houses carry a specific set of textures, and reproducing them is hand work rather than a product.

  • Orange peel, the most common, and the most unforgiving because the size of the droplet has to match

  • Knockdown, where the timing between spraying and flattening decides the pattern

  • Skip trowel and Santa Fe, which are trowel work and vary with the hand that did the original

  • Popcorn and acoustic on ceilings, with an important caution below

  • Smooth level five, which sounds easiest and is the least forgiving of all, because there is nothing for the eye to lose the repair in

A sample board is worth the extra hour. Matching on the wall means every attempt is a repair of the previous attempt.

Popcorn ceilings: stop before you scrape

This deserves its own warning.

Acoustic ceiling texture applied in older construction may contain asbestos, and disturbing it releases fibers. Scraping first and asking later is the wrong order.

Testing is inexpensive and fast. If the material tests positive, removal is regulated work with specific requirements, and it is not a weekend project. If it tests negative, it is simply a messy job.

Nobody should scrape an unknown ceiling in an older house. That is the whole message.

Plaster is not drywall

In older Los Angeles houses the walls are frequently lath and plaster, and it behaves differently.

  • Plaster is harder and more brittle, and it cracks along lath lines rather than at joints

  • A hole in plaster usually means the keys behind it have broken, so the repair has to re-anchor the surrounding material before filling anything

  • Patching plaster with drywall compound produces a patch that shrinks and cracks at the edge

  • A crack that keeps returning in the same place is structural movement, not a plaster problem

That last point matters. Repeated cracking in the same location is information, and filling it repeatedly is treating a symptom.

When the hole is not the problem

Drywall that is soft, stained or crumbling at the bottom of a wall is reporting water, and patching it seals the evidence in: water damage restoration.

Where water has been present long enough, the framing behind it is the real question: dry rot repair.
