"We hired ThermaCore Insulation to remove our old attic insulation, air seal the attic, and install new insulation. Kamal and his crew were professional, honest, and easy to work with from start to finish. During the inspection, they found several air leaks and duct issues that other companies completely missed. They explained everything clearly, completed the work on time, and left the area clean. We noticed a big improvement in comfort right away. Great service, fair pricing, and quality workmanship. Highly recommend ThermaCore Insulation!"

"Attic Experts pulled out our old insulation and installed new. Since then, we've certainly noticed a positive difference in how well the house keeps cool in summer and warm in winter."

Customers say: True professional

"Moshe and his team at Attic Kings are amazing! When I contacted them, they got back to me almost immediately with a date and time for an estimate to install insulation. Moshe was very communicative, texting and calling to let me know when he would arrive. On installation day, Moshe made sure to keep everything as clean as possible, and everything went incredibly well. They are all so kind--would definitely hire again!"

"American Attic was everything they promised. Met with the owner , Sam, within a day to get a quote for removal of old insulation, rodent control and install of new insulation. He was professional and explained everything in detail of what was work was going to be done and how long it would take. We scheduled within a week at a reasonable price. His crew were neat, organized and finished on time! We were notified of some extra things that were found while they were on the job but were not pressured to have those things done. We recommend American Attic to friends or family and would definitely use them again."

"When Insulation Alliance came, they were very professional. They laid down plastic everywhere in the hallway and the bedroom. They cleaned out the whole attic. They took out the old insulation and put in the new Insulation which was R 44. They cleaned up everything and everything was clean when they left. They also sanitized the attic. You will not be disappointed that you hired."

"Javier and his team were prompt every day, took care to cover anything even slightly near the worksite and leading to it in plastic, and removed all existing insulation in one day (using a large vacuum, which also removed rodent droppings). They then built a great 8'x8' raised storage area (with insulation underneath) and replaced the old material with blown-in cellulose. Between removal and new insulation, they crawled all around the attic and covered up any potential rodent entry points, pointing several out on the inside and outside of our home. They also filled a large opening that went behind our BR closet and filled the areas above the knee walls so our sloped master ceiling now had insulation. Exceptional!"

Drywall Insulation questions, answered by experts

Popular wall textures include orange peel, knockdown, spray sand, and smooth finishes. Orange peel and knockdown are particularly common choices for drywall as they are simple and cost-effective. Orange peel texture has a lightly bumpy surface resembling the skin of an orange, while knockdown (sometimes called knockout) looks like a stucco finish with flattened high spots. In contrast, popcorn texture has fallen out of fashion, partly due to its past association with asbestos and a shift toward more restrained interior design styles.

Yes, taping inside corners is a critical step in the drywall installation process.  Properly taping inside corners is essential for achieving a professional look, and an installation that resists cracking and maintains its integrity over time. Taping the corners involves the application of a joint compound along the seam where two drywall pieces meet. This process provides reinforcement, conceals the seam, and prevents future gaps or cracks from developing.

When doing a DIY paint job, it can be tricky to achieve the perfect, straight line between your wall and ceiling. There are several methods, including lining it with painter’s tape and using the “cut in” brush tactic. Some homeowners choose to apply a thin line of caulk to the wall-ceiling seam to create the appearance of a perfect line.

Whether it’s better to screw or glue drywall depends on your specific budget and project timeline. Professional drywall installers are more likely to use screws and fasteners than adhesives, but it takes longer. But if you are DIYing your drywall installation, glue is a perfectly fine choice if you’re willing to pay extra for adhesive.

Although they are used for similar tasks, spackle and joint compound are not the same. Joint compound, also known as drywall mud, consists of limestone and gypsum and is primarily used for large-scale projects like taping and finishing seams on new drywall. Spackle is composed of gypsum and binding agents, making it a thicker compound best suited for small wall repairs like filling nail holes or cracks, as it dries quickly and is easy to sand. For small repairs, either product can be suitable. However, you can use joint compound for small jobs in place of spackle, but you cannot use spackle for large-scale taping and mudding projects.
