Q: Why is my ceiling cracking where it meets the wall?

• <div><p>Common causes of ceiling cracks along drywall seams include poor drywall installation techniques, structural issues, truss uplift, and foundation problems. Temperature and humidity also play major roles in ceiling cracks flush with the wall. As the drywall shrinks and expands from major temperature changes or extreme humidity shifts, this can cause the drywall to crack.</p></div>

Q: How do I match the wall texture after making repairs?

• <div><p>It may take a bit of patience and trial and error to match your particular <a href="https://www.angi.com/articles/drywall-texture-tips-and-trends.htm">drywall texture type</a> when making repairs. For orange peel or knockdown finishes, use a spray texture product or a thinned joint compound applied with a roller or sponge. Practice on scrap drywall or cardboard first. Once dry, lightly sand and prime before painting. </p></div>

Q: Can I repair plaster myself?

• <div><p>While it is possible to repair minor plaster cracks or holes yourself, it is generally not recommended for larger jobs or if you want a professional result. Plaster repair can be difficult in practice; proper wall preparation and achieving a smooth, seamless finish that blends with the existing wall requires experience, especially on textured surfaces. Hiring a professional ensures the repair will be durable and last longer, potentially saving you money over time. A pro can also determine if the cracks are from normal expansion or a more serious underlying issue.</p></div>

Q: How do I find a good plaster repair company?

• <div><p>If you&rsquo;re looking for a reliable plaster repair company, you should start by researching local companies in your area and reviewing their status with the Better Business Bureau. Next, you can contact the potential companies to ask about experience levels, get a list of references, and ask for examples of past work. If you have a textured wall, consider asking if they have examples or references for that particular texture. This method should help you narrow your search even further. You may also want to ask each company if they provide a warranty for their work.</p></div>

Q: What damages plaster?

• <div><p>Plaster is a pretty tough surface, but it can still sustain damage from things like bumping against it, water issues, dampness, extreme humidity changes, and plain old age. Most plaster walls last hundreds of years and will only be taken down to the base layer when major repairs are required. Being cautious around the wall, not placing furniture against it, and ensuring stable humidity are all great ways to reduce possible damage. </p></div>

"Project: Repair and partially replace stucco surface of small retaining wall. Phil met with me and we discussed how to treat a short retaining wall that was losing the stucco surface after about 4 years since it was originally plastered. The wall was alowing water seepage to come thru the concrete block and lifting the original stucco finish off. Phil suggested a repair , consisting of first scraping all loose stucco off the wall and then applying an adhesive type undercoat followed by a total restucco of the wall. It was done very professionally , minimal debris, 2-day process , and it looks great. Now I just have to see how it holds up over the next 4-5 years . Highly recommend PG Plastering."
