Even if you don't go into restoration work the shop can be a nice addition to your growth.
With the restoration just be prepared for every holiday being consumed with an emergency phone call (people are home breaking their homes that day) and at the end of each day when people arrive home you being called out to what can be another entire day's worth of work... And after a late night of clean up and gutting walls (with your lead paint and asbestos certifications of course) needing to be at your carpet cleaning jobs after a quick baconateor and a shower.
Doing restoration takes a special breed... We did it for many years also. Got tired of the insurance industry price fights and homeowners running off to the carribeans with the money.... and going through the headache of trying to collect, or wait for them to sell their home with the lein put on it.
I am very happy (and so are my brothers) now that we don't do that work anymore. I just sold some of my final pieces of water restoration equipment a month ago. Was saving it for that "just in case" moment.... Nope... We just don't do it anymore. This actually helped me to focus on what we do more and it made our carpet cleaning business stronger.
I am actually purging my shop currently. I still have equipment and products that were new or slightly used... Now just dumping.
But I am very happy for you... I just want you happy also and go cautious before jumping in is my words of caution.
Be happy in life!
