Work Description: Handyman: Re-grouting tiles/floor/ silicone around bathtub
Comments: This review is for the handyman section of the company:Tiles were damages when the handyman used an electrical tool to cut out grout, dust was all over the apartment and the fire alarm was set off, the fixtures were not take off and it was grouted around the towel holder and mirror, grouting itself is not satisfactory and appears below standard. After the initial work appeared not standard I had a conversation with the owner and supervisor and I was told that the work would be done in an acceptable manner. The pictures I took every day and after do not show handyman work that I would consider ‘standard”. My concerns about workman ship were downplayed by the initial worker. Excuse for cutting into the tiles was “there was so much dust I could not see well” and “I did not have the tools “ for not taking off the fixtures after I pointed this out. The project was estimated for 2 days but lasted several days longer with an end-result that is poor in my opinion given hat I hired a professional handyman.

Work Description: Faucets/Fixtures/Pipes Repair/Replace
Comments: I had 2 faucets that were rotting out and leaking. Paul arrived on time and assessed the situation and costed out replacements. I opted for a more expensive faucet on both and agreed to their price.Paul and Pete arrived the next day on time and I now have 2 new faucet that don't leak.
I will use Cornerstone Services in the future for additional work both inside and outside the house.
