"This is a multi family  residence, more like an income property. After the use of many years and many cars in and out of the driveway. It had to be repaired someday. These guys came in quick and repaired and sealed the driveway. Took a few days but the final work was great!

"After searching online and interviewing a few contractors we found just do it builders on Angies list. From the beginning we had a very good chemistry with Eric the owner. A factor that was really important to us. My husband and I decided to go with him and we were very pleased with the outcome for our project. As Eric promised the remodel took almost 4 weeks. They remodel our kitchen completely with new cabinets, new granite counter top. We also changed the floors to hardwood floor and we also added recessed lights and few outlets in dining area. What I like the most with this company is that every morning we got a phone call from the project manger in the office about the schedule of every day, we knew exactly when the guys are coming to work and we were updated with the stages of the project. Communication was great and helpful for us. The crew kept our house clean as much as they could. They took the trash every end of the day and really made the process easy and comfortable experience as it can be. I will definitely recommend just do it builders to my family and friends. We are thinking to remodel out bathroom soon and I already contact Eric for a quote. Thanks again for such a beautiful work we love our new kitchen!!

"Matt came to inspect our roof and found another tile that needed to be replaced in addition to the 2 that were already broken. He came the next day to do the job. In addition to replacing the tiles, he fixed other tiles that were previously repaired by another company. He was efficient and did an awesome job. Reasonable price and would use him again for any future jobs."

"Phone calls were handled in a personable and timely manner, as were emails. The job was completed quickly, with precision and skill. Alex even went as far as "fixing" and covering up some patches made by another plasterer... never mentioned that the previous job looked awful... just fixed it at no extra charge. Would I hire Trifecta again? In a heartbeat.

Plaster Repair FAQs, answered by experts

Yes, you can install drywall over plaster, but there are important factors to consider. While it can create a smooth, flat surface, it is often not the best approach. Installing drywall over plaster will increase the wall's thickness, which can cause issues with existing window and door frames that may no longer fit. You might also need to adjust power outlets to keep them accessible. A better, though more expensive, option is to remove the old plaster and lath entirely before installing new drywall. Drywalling directly over plaster seals in the old material, and if any problems arise later, you will need to remove both layers down to the structural beams for repairs. Given the potential complications, this job is best handled by professionals.

Repairing plaster walls or ceilings is almost always worthwhile. It restores the appearance of your home, and if it's an exterior wall, the repair can improve curb appeal and provide a great return on investment when selling. Plaster repairs can also reinforce the wall, preventing minor cracks from spreading, and improve your home’s energy efficiency by fixing gaps in the insulative material, potentially lowering your heating and cooling bills. Additionally, hiring a professional allows them to check if the damage is from a serious underlying issue, such as foundation instability. Catching a problem like this early could save you thousands.

If the holes in the plaster are small, you can fill them with layers of patching plaster until they’re filled. After it dries, you can sand the plaster and paint over it. If the hole is much larger, consider using bonding plaster first and then a layer of patching plaster, completing the process with sanding and a layer of paint.

The short answer is yes, a sagging plaster ceiling is dangerous. Sagging plaster on a wall is something you should fix immediately, but it isn’t a major concern. If the same type of sagging occurs on a ceiling, however, you could be in danger of your ceiling falling in large chunks. When plaster sags, it loses its strength and ability to hold itself up. The bonds that hold it together are strong, though, so if a sagging area falls, it will take large pieces down with it.

If your premixed drywall mud is dried out or has begun to set in the bucket, you may be able to revive it by adding warm water and stirring. However, the first and most important step is to scrape off any hard, dried bits of drywall that may have accumulated toward the top of the container and throw them away because they will not easily reconstitute back into the drywall mud mix.
