"We were referred to AJ Pro Green by a colleague so we had them come out for a free estimate. They showed up on time and were very professional. They insulated our basement during our remodel and we couldnâ t be happier. The job was done quickly, was within our budget, and communication was fantastic. We would highly recommended!"

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

Mr. Mom helped us save costs by painting some of his leftover gutter materials so they would not clash with the rental house, and finished the job quickly so we could have it done before more rainstorms caused flooding in the basement.

Drywall Insulation FAQs, answered by experts

Drywall can get wet and dry out without sustaining permanent damage, but only if the water damage is minor. If you have a small leak and are quick to correct the issue and set up blower fans and dehumidifiers, your drywall should dry out. If the leak is persistent, the drywall becomes totally waterlogged, or mold begins forming on the drywall, you should remove and replace it.

It’s always better to follow proven drywall repair tips and fix the seams that look bad. However, if you simply want to make them less noticeable until you have time to fix them, you can use paint. A darker color of paint makes bad drywall tape seams less noticeable than light-colored paint. Matte paint hides bad seams better than glossy paint does, too.

Small patches can be DIY, but professionals handle large-scale repairs with seamless results.

The easiest way to cut holes in drywall for electrical boxes is to use a spiral saw with a drywall router bit. Hang the drywall without cutting out a hole for the box, but make sure you measure and mark where the box is located on the wall. Once you screw in the drywall sheet, drill a small hole into the box void, insert the spiral saw bit, and move it around the edge of the box using the inside wall as a guide. You can also use an oscillating multi-tool with an electrical box cutout for fast, professional results.

A local drywall contractor can texture your drywall for you. Drywall contractors are a better choice than general handy people because the contractors have a lot of experience working with drywall mud. The process is somewhat of an art thanks to the complexity of working with the mud, so call in a drywall pro who knows what they’re doing.
