I don't think we'll ever own another home without going through this process. I was shocked, and actually appalled, that we actually had interior doors in the place where exterior doors were supposed to be. We went from needing to keep blankets around all the time to draft free living. We would've never known and simply lived with the inconvenience for who knows how long.
Living on the other side of this process gives me the peace of mind to know that our home is truly sealed. That was made even more of a priority when we were enjoying a TV show with our two year old and an eight-foot snake came slithering through our living room. Needless to say, it was a stressful night at the house. This process found every vulnerable spot in our home. Face it...we live in an old house in the country. Varmints are a way of life. Since finishing this process, we've seen no bugs, mice or, thankfully, snakes!
The other big change was our basement. It was a musty, moldy mess. Now, we were given the confidence to finish it out, and our kids enjoy it as their playroom. It's sealed from all water intrusion and the air is well conditioned in the area. Mold and must are things of the past.
We're committed to this process not only for any home we own or will own, but for every home that is owned by someone we love.
