Drywall and Plaster Repair Guide

Last Updated: March 7, 2017

Some people are naturals when it comes to home repairs. They never seem to need a measuring tape and nail everything the first time. These skilled handymen can fix pretty much anything that comes across their path. The rest of us fail spectacularly from time to time, and we either have to redo the entire thing or call in an expert.

We’re telling you this because repairing drywall and plaster isn’t very difficult to fix or install in theory. But, as many years of experience has taught us, messing up is easier than repairing.

In this short guide, we will go over a few basics. First things first, let’s talk safety.

The Weight of the Drywall : Depending on the damage, you might have to buy one or more sheets of drywall. Keep in mind that one sheet weighs almost two pounds/square foot, so things can get out of hand quickly if you are not careful.

Beware of the Dust : Wear a dust mask when grinding to avoid inhaling silica and gypsum particles. Remember that sanding dust is a respiratory irritant. Use a cloth or damp sponge to dust off the wall and clean the area.

Now that you know some safety tips and what you need before you start, let’s move on to the actual steps for repairing drywall.

  1. First, make sure you have the right tools. Here is some equipment you will need: dust mask, vacuum, utility knife, pencil, a wall repair patch, tape measure, joint compound, water-based primer, joint knife, sanding block and a paintbrush.
  2. Before starting to fix, you must clear any loose debris and remove any dangling pieces of plaster or drywall.
  3. Take off the liner from the wall patch, place it over the damaged area and press firmly to seal the corners.
  4. Now, it’s time to apply the first layer of joint compound. Let it sit until it dries completely.
  5. Sand the area and then apply a second coat of compound.  
  6. Time for some more sanding. Repeat these last two steps until you are satisfied with the result.
  7. The last step is to paint with a water-based primer and let it dry before going with the paint color.

The process described above describes a “best case scenario,” so it would be pretty hard to make any mistakes. However, if the damage is significant you should probably keep in mind the following tips:

  • Battered Corners: If you are dealing with this problem, the first thing you’ll need to do it to remove the metal. Then, use a lever to clear away the damaged section. Mark the length of the new corner bar by holding it in place. After you have cut the new piece of the corner bead, fix it in place with nails. The last step is to add a few coats of drywall compound using a taping knife.
  • Creeping Cracks: Start by smoothing the cracks with an abrasive foam block. Apply a thin coat of joint compound to the damaged area and sand it until smooth. In the end, apply an elastic crack spray to set everything in place.
  • Soggy Ceilings: First, apply a stain sealing primer. Then apply a blend of drywall compound thinned with water. After it has dried, add texture with a brush.

Repairing drywall and plaster isn’t necessarily difficult. However, there’s no shame in admitting that you aren’t a natural born handyman and call in an expert to fix it for you. Don’t hesitate to contact us if you want a hand!

Older wood siding can give a Corvallis home a lot of character, but it also needs the right care before repainting. If your siding looks faded, peeling, cracked, or weathered, paint may help restore its appearance and protection. However, older wood siding should be checked for moisture damage, failing paint, soft wood, and proper prep needs before any new coating is applied. Painting over problems does not make them go away. In many cases, the most important part of the project happens before the first coat of paint goes on. A careful inspection, thorough prep work, and the right exterior painting process can make a major difference in how long the finished result lasts. Why Older Wood Siding Needs Extra Attention Before Painting Older wood siding does not behave the same way as newer siding materials. Wood can absorb moisture, expand, contract, crack, and show signs of age in ways that are not always obvious from a distance. A home may look like it only needs fresh paint, but once the surface is cleaned and inspected, there may be soft boards, open seams, or areas where old paint is no longer bonded well. This is especially important for older homes in Corvallis and the surrounding Willamette Valley. Many houses in the area have been through years of rain, shade, damp winters, and seasonal temperature changes. Over time, those conditions can wear down paint and expose the siding underneath. Before repainting, homeowners need to know whether the siding is still sound enough to hold paint properly. How Corvallis Weather Affects Wood Siding Corvallis weather can be tough on exterior wood. Wet winters, damp spring conditions, tree cover, and moss-prone areas can all speed up paint failure. Even when a home looks fine during the drier months, moisture may have already worked its way into weak spots around trim, lower siding, windows, or shaded walls. The shaded sides of a home often show wear sooner than areas with better sunlight and airflow. North-facing walls, areas under trees, and spots near landscaping may stay damp longer after rain. That extra moisture can lead to peeling paint, mildew growth, swollen wood, and surface damage. Because of this, painting older wood siding in Corvallis is not just about choosing a new color. It is about making sure the siding is dry, stable, and properly prepared for long-term protection. Signs Your Wood Siding Needs More Than a Quick Repaint A quick repaint may improve the look of a home for a short time, but it will not solve deeper siding problems. If the paint has failed because of moisture, rot, poor prep, or damaged wood, the same issues can come back after the new paint is applied. Before repainting older wood siding, homeowners should look for signs that repairs or extra prep may be needed first. Peeling Paint That Keeps Coming Back If the same areas keep peeling year after year, there is usually a reason. Repeated peeling can point to trapped moisture, poor previous prep work, or an older coating that is no longer bonded well to the siding. Simply painting over those areas may cover the problem temporarily, but the new paint may fail again if the surface underneath is not properly scraped, sanded, primed, and prepared. Peeling paint is especially common around areas that hold moisture, such as lower walls, window trim, and shaded sides of the house. These spots should be checked carefully before repainting. Soft Wood Near Trim or Lower Siding Soft wood is a warning sign that should not be ignored. Areas near the bottom of walls, windows, doors, and trim are often more vulnerable because water can collect, splash back, or enter through gaps. If the wood feels soft, swollen, crumbly, or weakened, paint will not fix it. Damaged wood should be repaired or replaced before painting. Painting over soft or rotted wood can trap moisture and make the problem worse. It can also shorten the life of the new paint job because the coating needs a solid surface to bond to. Cracks, Gaps, and Open Seams Cracks, gaps, and open seams allow moisture to get behind the siding or into trim joints. Over time, that moisture can lead to swelling, rot, peeling paint, and more repairs. These openings may be small, but they can have a big impact on how well the siding holds up after painting. Before paint is applied, failing caulking should be removed where needed, gaps should be sealed properly, and damaged areas should be addressed. This helps create a tighter exterior surface and gives the new paint a better chance to last. Why Prep Work Matters More on Older Siding Prep work is one of the biggest factors in how long an exterior paint job lasts, especially on older wood siding. If the surface is dirty, loose, glossy, damp, or damaged, new paint will not perform the way it should. Older siding often needs more detailed preparation because it may have layers of old paint, uneven surfaces, exposed wood, or problem areas that are easy to miss. A proper prep process may include washing the siding, removing loose paint, sanding rough edges, spot priming bare wood, sealing gaps, repairing damaged boards, and making sure the surface is ready for finish coats. These steps take time, but they are what help the paint bond correctly and protect the siding longer. Skipping prep may save time upfront, but it often leads to peeling, cracking, and repainting sooner than expected. Should Older Wood Siding Be Painted or Repaired First? Paint is designed to protect sound siding, not repair damaged siding. If the wood is still in good condition, a professional exterior painting project can help restore the home’s appearance and protect it from future weather exposure. But if there is rot, water damage, loose boards, or failing trim, those problems need to be addressed before painting. A professional inspection can help homeowners understand what the siding actually needs. Some homes only need minor repairs, targeted scraping, priming, and repainting. Others may need board replacement, trim repair, or more detailed prep before paint can be applied. Knowing this ahead of time helps avoid wasting money on a paint job that will not hold up.  For Corvallis homeowners, this is especially important because moisture-related siding issues can be easy to overlook until the surface is closely inspected. Getting the condition of the siding right first helps protect both the finished look and the home itself.
