"Edgar listened to my request to perform the tasks of insulating the HVAC ductwork and hotwater lines before installing the R30 batts in the joists. He did a good job in cleaning up the fallen insulation pieces from the floor, but there was still residual insulation dust on the floor and on my storage boxes. The tape he used to secure the ductwork insulation batts kept coming undone after he left, which I later re-taped myself. Overall, the quality of the work was great, but the cleanup could only be rated as 'Good'."

"I had Javier check to see if I needed new underbelly insulation on our mobile home. I could not crawl under the trailer to see if this work was needed. He could have taken advantage of the situation, but said all I needed was two patches and ground cover. They actually installed three patches with no additional cost. Honesty, integrity and professionalism are key to this business."

"Did a great job on the insulation however they left a hole in the ceiling when they dropped something on the attic floor. Not a big deal but they need to be careful. Overall, amazing work they do all kinds of insulation and they also install radiant barriers on roof joists. They are reasonably priced and the crew is super friendly, pleasure to work with."

"We were extremely happy with our recent service. We really liked that he showed us the aspects of our dryer and vent and how we can keep it clean on a weekly basis. He was very tidy too! I would definitely recommend him and plan to have him return each year."

Drywall Insulation FAQs, answered by experts

Yes, you can speed up the time it takes for plaster to dry, but it's important to do so carefully to avoid issues like cracking or crumbling. Proper ventilation is key; open a window or use a fan to circulate air in the room. Heat can also accelerate drying, but be cautious, as too much heat can cause the plaster to dry too quickly and crack. Check the plaster's packaging for the recommended drying temperature and set the room's thermostat accordingly. While managing humidity is important, avoid using a dehumidifier, which can remove moisture too aggressively and result in crumbly plaster.

In some minor cases, you can DIY drywall repair with minimal time and money spent. This method is best when you have a hole made by a singular problem, such as accidental furniture moving, and not a continuous problem, like a rodent infestation. 

Knowing what product to use is crucial. For example, small holes only need spackle, whereas large holes might need a new piece of drywall. You can flex your DIY abilities on this project, but if you’d like a second opinion or have a more significant problem, it’s best to call in a drywall repair pro.

There shouldn’t be any gaps between your walls and ceiling. These can be fixed with joint compound but that is only a fix, and it’s much better if your drywall fits correctly in the first place. Sometimes gaps can appear if your foundation shifts significantly but if this is the case, you have a much bigger problem than patching drywall.

Drywalling a garage is a smart decision if you want to protect your garage from fires, moisture damage, and exterior noise. Most garages have flammable supplies that could result in serious damage in the off chance of an accident. Drywall is fire resistant, helping to prevent fires from spreading. Not to mention, drywall can improve the appearance of a dingy, old garage.

Eco-friendly options reduce environmental impact and often improve indoor air quality.
