We live in a recently completed townhouse that was built with double-wall construction. That construction method was touted by the builder as what would keep sound from penetrating between the units. But we can hear the next door neighbors' TV and stereo, and sometimes voices and even snoring, through the wall. While sometimes it's the volume, mostly it's the bass sounds coming through the wall. They say they don't hear us, but we keep our bass turned down. They crank up the bass, and they are not going to change that. They also are not going to do anything construction-wise to help from their side. What is the best way for us to try to block the low frequency/bass sounds from penetrating the existing wall into our side?
Professionals can replace garage door springs in an hour or two. When you hire a pro, make sure to ask about the quality of the springs they will install. They may well offer several grades of springs to choose from, at a range of costs. Top of the line springs may be guaranteed for life, while economy springs can be expected to last perhaps five years under normal use.
4.4 Take the spring on the left and place it at the left end of the door as pictured here. Notice that the end of the wire points to the right toward the center of the door. This is a right wind torsion spring. It will go above the garage door on the left side of the spring anchor bracket. The winding cone at the other end of this spring is usually painted red.
