I waited to rate until after our first good rain storm. The new door installation is fantastic! We no longer have water leaking into our garage. The new installation is superior to what was originally installed. Robert was a dream to work with and I highly recommend him.

Bonafide flooring design did a great job with our install. About a week from quote to install - fast, efficient, affordable quality work. We didn't have the transitions when the team did the initial install, but they came back to see that the job was done once the transitions arrived!

I hired Korish to investigate why the doorbell and chime did not work. Korish spent a long time checking every combination of the 6 wires in each of the two cables to identify the problem. Korish only charged me the initial quoted price. Honest and hardworking!

Doorbell Installation FAQs, answered by experts

If you’re using faced insulation with paper, face the paper toward the inside of the room during the installation process.

A good way to remember this is that the paper should face the “warm side” as it’s the vapor barrier, meaning it should face toward where the heat will be coming from.

Yes, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces.

While not every wall requires a vapor barrier, if you do need one and don’t install it, moisture can get between the walls of your home. This can lead to water damage from mold growth or rot, and the excess moisture could also attract pests, including termites, cockroaches, or ants.

Upgrading insulation offers several benefits, including improved energy efficiency, which leads to lower heating and cooling costs. It also enhances indoor comfort by regulating temperature and can provide noise reduction. Additionally, better insulation has a reduced environmental impact and can increase your home's value and overall livability.

It’s best not to install a radiant barrier directly under insulation because it requires an air gap on at least one side to work properly. Instead, you should install the radiant barrier over your existing insulation to create an air space to reflect the radiant heat.
