"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."

"I RECENTLY HAD MY ATTIC INSULATION REPLACED BY MASTER ATTIC. ALEX CAME OUT RIGHT ON SCHEDULE AND GAVE ME A FAIR PRICE. ( I DID HAVE 4 OTHER ESTIMATES) THE CREW LEAD BY ROBERTO WAS AMAZING. THEY WERE VERY CONSIDERATE, CAREFUL IN MAKING SURE THE AREA WAS SEALED OFF AND WERE VERY CAREFUL OF MY PERSONAL BELONGINGS. THEY DID A GREAT JOB IN REMOVING OLD INSULATION , VACUUMING OUT THE ATTIC ,SPRAYED AREA AND SEALED ANY OPENINGS. BEFORE THEY BROUGHT IN NEW INSULATION, THEY ASKED ME IF I WISHED TO TO VIEW THE ATTIC AND I DID. I WAS AMAZED EVEN AT THIS POINT, HOW CLEANED EVERYTHING LOOKED . (THIS INSULATION HAD BEEN UP THERE FOR 70 YEARS) NEW INSULATION WAS INSTALLED AND IT LOOKS GREAT. THE CREWED CLEANED UP EVERYTHING , EVEN VACUUMED THE AREA IN THE ROOM. ALL BAGS OF OLD INSULATION WERE REMOVED PROMPTLY AND I WOULD HIGHLY RECOMMEND THEM TO ANYONE."

Drywall Insulation FAQs, answered by experts

In framing, studs are placed at 16-inch intervals to coincide with the typical spacing of wall materials such as drywall or plywood. This spacing is called "on-center" and is necessary for maintaining structural stability and efficient use of materials. The 16-inch spacing also helps to distribute the weight evenly across the building's structure. For those looking to cut material costs and improve energy efficiency, 24-inch stud spacing can be employed through a method called "advanced framing". This requires careful planning and adherence to local building codes to ensure structural integrity.

When you are learning how to tape and mud drywall, waiting for things to dry requires a lot of patience. So how long does drywall mud take to dry? On average, it takes about 24 hours. However, it depends on things like the thickness of the mud, as well as the room’s temperature, humidity, and ventilation. Using thin layers of mud in a warm, low-humidity room with good airflow reduces average drying time. You also could speed up drying time by making use of hot drywall mud, which consists of a powder that you mix with water, instead of using pre-mixed mud. 

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.

Walls should be as smooth as possible before applying peel-and-stick wallpaper. Although you technically can apply wallpaper on textured walls, the peel-and-stick variety won’t last long without a clean, smooth surface for the adhesive to stick to. If you have textured walls, consult a pro about removing the textured finish before moving forward with wallpaper.

It is possible to apply plaster on the interior or exterior of your home, but we don’t recommend it. Plaster is easy to apply in theory, but in reality, it can be a challenging material to work with, and it’s difficult to get the finished product to look clean, even, and smooth. Many DIYers end up calling in a professional afterward to touch up the area or even redo it entirely because of mistakes they made in the process. Hiring a plaster pro will cost more, but it’s usually the best option to achieve high-quality results.
