100% recommended!

Paul and his crew did a fantastic job replacing all the sheet metal flashing of our 1906 house in the Castro – he was quick to respond, flexible with timing, quoted us a fair price and most importantly did high quality work – 100% recommended!

I reached out to Paul and asked if he could help fabricate a cap for the sheet metal roof vent that had been broken. He asked the right questions, provided a reasonable quote, showed up Saturday morning and installed it in about 9-10 minutes. He was polite, organized and great to deal with. If I have any other sheet metal fabrication needs in the future, I will without a doubt contact Paul at MSM.

Super quick!

Super quick and good! Paul came the same day to size up my two skylights that needed replacement and repair, respectively, and did the work with his co-worker, as promised, the next business day. It all looks great! Happy to have this before we get more rain.
