Shawn was great to work with! He called me right away and came out that day to take measurements for us. Once the materials arrived he scheduled the install with me immediately and did a fantastic job for us. Do yourself a favor and work with Shawn on your next project, he's great!

They installed a fence a wall, a door, a railing and painted for us. They were quick, professional, respectful of our property and cleaned up after themselves. The best part was after the job was done we didn't need to pay a penny more then what they quoted us!

Doorbell Installation questions, answered by experts

If you need to insulate behind finished walls, the best option will likely be to have an insulation professional install blown-in insulation. The installation requires small holes cut in your wall, after which the installer can blow loose-fill insulation into the void. After the installation, you’ll have minor drywall patching, which shouldn’t cost more than $100. Compared to ripping down the existing drywall, using a different type of insulation, and replacing and finishing the drywall, this should save you hundreds or even thousands, depending on the size of the room you’re insulating.

Insulation is professionally installed by measuring spaces, cutting materials to fit correctly, and placing them without gaps for optimal thermal resistance.

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.

When installing board and batten siding, make sure there is wall sheathing and a moisture-resistant barrier installed. Behind that sheathing should be plywood or OSB for you to nail the boards and battens into. If there isn’t plywood or OSB, you can install vertical furring strips at 1½- to 2-foot intervals to nail the boards and battens to.

Doubling the insulation in your home also doubles the R-value of said insulation. In other words, by adding more insulation, you can reduce the heat loss by half. Most homes benefit from increasing insulation. Older homes, in particular tend to have less insulation as is, so doubling your insulation could drastically reduce your energy bills, keep your home more comfortable, and take the strain off your HVAC system.
