"I hired Zavza Seal LLC to waterproof the foundation in my basement. Anderson and his crew went above and beyond with the project. They were on time, clean and responsive to any questions I had. I would gladly use them again."

"I researched and found Devon and his company were very well reviewed and he was great on the phone. We have a 1904 home with vermiculite and old batting for insulation in the attic. Devon came out to the house and was planning to do the removal of the old insulation but the vermiculite was determined to have asbestos, so we had everything in the attic remediated. Devon told me about the ZAI Trust and I was able to submit a claim for the abatement and reinsulation. Devon also discovered that a small roof off the kitchen/dining area was uninsulated as well as the dormer roof and the ensuite below it. We had to reschedule suddenly due to Mum being admitted to the ER, and Devon had no issue with this at all, and was very supportive. Devon and his team did an amazing job! What great people! They worked so hard and the spackling job to cover the holes was terrific. We just primed and painted. Devon will be back here to review the insulation status in the rest of the home, as the old foam insulation may need to be supplemented. I'd hire Go Go Green Insulation in a heartbeat and have already recommended them to a couple of neighbours. Old home, apt. or new build, these guys are the BEST!"

"They insulated my attic, which was done very well and efficiently. But I was most impressed by the consultation they gave on the insulation issues on my first floor. The guy, Brad, gave quality free advice rather than making up a huge project that his company could profit from. Will be hiring them for my next insulation project!"

"I needed the attic of my 2 car garage insulated as well as some exterior wall on the main level. The job was done in one afternoon, including installation of Geeenrock on the lower level. Everything is buttoned up neatly and tightly and it is now easy to warm the space with a small heater. I would definitely recommend this company! Their cost was 1/3 the cost of the batt insulation alternative I researched and result is exactly what I was hoping for. Gary Centerport, NY"

"The crew showed up wearing booties and proceeded to protect my flooring and carpet.  They removed the moldy drywall and left my basement spotless.  I would recommend them to all of my family and friends who may need their services.

Drywall Insulation questions, answered by experts

You’ll want to inspect your plaster walls for signs of damage before painting. If you notice soft spots, deep cracks, bubbling, or areas where the plaster is crumbling or pulling away from the wall, it likely needs repair. While small hairline cracks are common and likely cosmetic, you should address larger issues before painting to ensure a quality, smooth finish.

Plaster provides a durable, soundproof, and moisture-resistant finish compared to drywall.

If you're comfortable hanging drywall yourself, you may be comfortable finishing it. But it's worth noting that finishing drywall adds several steps to the process and a lot of waiting time. Hiring a drywall installer may be the way to go if you'd rather spend your time doing other things or are nervous about leaving a rough surface.

Mudding drywall is a DIY-friendly project, but patience and practice are required for perfection. If you’re working in a highly visible area and want the best possible finish, hiring a professional drywaller is worth the cost. Pros have the tools and know-how to ensure a smooth surface with fewer sanding sessions and less cleanup.

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