"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!"

"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"

Eco Green Solutions were great to deal with.  They came to the home for an initial consultation and provided me with great solutions for the heat loss problem I had in the home.  The salesperson provided me a clean understandable proposal with different options I could choose from depending on my budget.

When we agreed upon the scope their office scheduled an appointment with me to schedule the work.  Their crew showed up on time, wore booties on their feet to keep my floors as clean as possible and did a remarkable job patching and priming the walls for painting.  I wasn't home when the work was performed, but the painting contractor I had in the home at the same time commented on how professional they were and how they made his job so much easier.

As a homeowner, heating and cooling cost are real concerns.  I highly recommend anyone considered with those things like I am to have Eco Green Solutions do an energy audit of their home and see where they can save.

Drywall Insulation questions, answered by experts

When sanding drywall mud, you’re going to create a very fine dust that may contain silica. Silica dust contains crystalline silica, which can cause long-term illnesses for people who inhale it in significant quantities. Wear a mask while sanding drywall. Then dampen a drywall sponge to wipe the dust off the drywall, helping to reduce the amount of dust that may become airborne.

Plaster is denser, harder, and more porous than drywall, so it absorbs moisture differently. This means you’ll often need more prep work, such as thorough sanding, patching, and priming with a high-quality bonding primer. Additionally, you may need more coats of paint to achieve even coverage. While the process takes more time, it helps ensure a durable and professional-looking result.

Applying plaster to a wall will usually cost between $2 and $10 per square foot for both the material and labor. The cost will vary based on the quality of the plaster you’re using and whether or not prep work is required before the work begins. Wall prep can add up to about 10% to your total costs. Plastering exterior walls can be more expensive in many cases because they are taller and require scaffolding and safety equipment.

All plaster walls will crack over time due to normal house settling and expansion and contraction from temperature and moisture changes. Small, thin hairline cracks are generally not serious and are mostly a cosmetic issue. However, larger or more significant cracks can indicate structural problems.

Here's how to tell the difference:

  • Cosmetic Cracks: Cracks that are 0.5 cm (0.2 inches) or thinner are typically cosmetic.

  • Structural Cracks: Cracks wider than 0.5 cm, excessive or deep cracks, multiple cracks in the same area, or cracks that span around corners can signify a structural or foundation issue. Cracks along the joints where walls meet the ceiling also warrant attention.

For cracks wider than 0.5 cm, structural repair is needed. If a crack is 2.5 cm (1 inch) or wider, or if you notice any signs of a structural problem, it is best to contact a plaster repair professional to assess the damage.

Drywall mudding can be done in one day if the project is small and the desired effect isn’t too complex. If you need multiple layers of mud, one day may not be realistic. But a single room that requires little more than joint compound on the seams and screws can be done in a day or two.
