"FoamCo recently insulated our basement walls. Before, we couldn’t use the basement in the winter time. We noticed an immediate difference once the insulation went in, and now our basement is our favorite cozy hangout spot in the house. They were great at explaining exactly what kind of insulation I needed and were actually the best priced bid we got."

"Tim and Jeff were very fastidious in setting up, cleaning, and making sure the house was in good order when they left . We also had an Aeroseal treatment which followed with James and Connor. It did take some time to set up after the vents were cleaned and blown out, but the application of this polymer to close gaps in lthe galvinized steel ducts was remarkable."

"He was very knowledgeable and professional. After the audit we received an estimate to correct any areas that were discovered. Unlike what we originally thought our issues were not the windows and doors. The estimate was for $4000 to add insulation to the attic, increase airflow in the attic, install foam insulation around our fireplace and throughout the basement as well as removing the attic fan and adding drywall. 
The price is the estimated price for projects to be completed.

Drywall Insulation FAQs, answered by experts

Pros ensure smooth finishes and lasting repairs, avoiding visible patches.

Regular inspections, repainting, and avoiding moisture exposure help maintain integrity.

Depending on the place where the cutting error occurred, you may be able to fix it. Learning how to patch a hole in drywall is challenging, but if you can tape and mud drywall, you can do it. Having said that, patching is time consuming. Early in the installation process, you may find that it’s easier and far less time consuming to just start over with a new sheet of drywall, cutting a new hole in the right spot. You may be able to use part of the incorrectly cut piece elsewhere, so it’s not completely wasted.

For maximum stability, install grab bars on wall studs, as this will adequately support the weight. However, if you don't have access to studs, you can get by with wall anchors. If opting for the latter, choose specialty hollow wall anchors. 

If you plan on heating your garage, you must install a vapor barrier when drywalling the garage. A vapor barrier protects your garage from frost and mold that can occur through condensation. If your garage is unheated, you don't need to install a vapor barrier. The only exception is if you regularly crank the heat in your car before getting in it. In this case, you may still want to install a vapor barrier, as your car can heat your garage.
