"Are your inspections free?" - Client

"Yes, most of our in- home inspections are free.

Some of our inspections will have a minimum charge, depending on whats needed and the time we will need onsite ( opening up drywall...) , this amount will be credited to the  the Installation/Repair work, when the work starts." - Dan Lynch

" Can I buy windows at your location and install myself?" - Client

" We are teamed up with the people at Marvin/ Integrity as a Dealer/ Installer.  That means that we install all the windows and doors we order from them.  This allows us to keep the costs on your replacement windows down and pass them on to the Homeowner.  We follow all the specifications from all of our dealers.  All of our installers take classes with Marvin windows. This allows the Homeowner to have the full manufacturers warranty.  Ask about OUR INSTALL WARRANTIES!!" - Dan Lynch
