Blown-In Insulation in the Plaster Walls

Bob again meets up with insulation contractor Joe Sheridan in the main house where the Cocoon insulation in being blown into the original plaster walls. To accomplish this, Joe's crew has drilled holes every 16 inches so that they are into every stud cavity. They drill one high and one low to acheive the proper density. First they apply it to the bottom and fill till it's solid in there - about 30 seconds on a bottom cavity. The installer can tell when it's filled from the pressure of the hose. The product will start backing into the hose. With experience you can hear it. Thge goal is to create maximum density in the cavities - leaving no air pockets. When the insulation process is complete a plasterer will have to come in and patch each hole individually.

Hurricane Straps, Clips, & Anchor Bolts

Your home's ability to resist the extreme force of wind is only as strong as its weakest link, so the only sure way to create a wind-resistant home is to secure all its connections: roof-to-wall, floor-to-floor and wall-to-foundation. The roof is your home's first line of defense from a storm. To make sure the roof stays in place when severe winds blow, securely anchor roof-to-wall connections by installing hurricane straps or clips at every wall-to-rafter connection to reinforce the roof. Even if re-roofing your existing home is years away, it is possible for roofing professionals to access and reinforce an existing home's roof-to-wall connections with hurricane straps and clips. These connections are critical in holding the roof together and will dramatically increase the homes overall resistance to wind. Along with roof-to-wall connections -- all joints in the structure -- floor-to-floor and wall-to-foundation -- must also be secured to create a "continuous load path" to the building's foundation. Secure floor-to-floor connections by making sure each floor is connected to the floor below with straps or clips in addition to any other code-required nailing schedule. Wall-to-foundation connections should be made through the use of anchor bolts or mud-sill anchors. Be sure to install all connectors following manufacturer's specifications.

Installing Molding

Dress up the rooms in your house with a variety of custom moldings. These moldings are available in many historic profiles. You can add a one piece baseboard molding for a 19th century look. Poplar chair rails and picture moldings add detail and take paint well. And for a more elegant look add a multi-piece crown molding to the ceiling.

Ladder Work

Here are some tips that will make working on a ladder easier. Use elastic cords to secure a small plastic basket to the top of your stepladder to hold your tools. If you're on an extension ladder, slide a broom handle through a hollow rung and hang a bucket for tools from that. Keeping your tools close at hand, you'll save several trips up and down the ladder.
