I want to impress upon you all how pleased I am with the work that Alex, George, Ashlee, me Arnold, and Shane did on my basement restoration. They took a basement that had no flooring and holes left in the walls and ceilings from a previous plumbing job, and not only patched it all up, but made it look way better than it already was. This team works really well together, and goes above and beyond to do an amazing job I definitely recommend them. I am extremely happy with the handyman work we had completed by Shane and Alex. As always, they left us very satisfied and happy with the work they completed please use cornerstone for your handyman needs. Alex, Shane, and George, fixed two doors in our house that would not open or close very easily. They took a tiny bit trim off of them and now they open and close with ease and very happy. Thank you to the cornerstone team for doing an amazing job like they always do. Alex and Shane did an amazing job pressure washing and staining my front porch, leaving it looking new and revived. As I have stated in previous comments before, this is an amazing crew that goes above and beyond, and deserves all the recognition. Ashlee and Alex worked really hard on my back deck for the last two days. They pressure washed it and stained it, and the ending job was amazing. I am very impressed and happy with anything this team has ever done for us, and our home looks amazing due to them.

My only problem with them was after the electrical work was done they failed to get a service permit to have the meter put back. . We spent an extra week and a half in a hotel which we didnâ t need to do.

Bill and Wade were great. They were right on time (very important!) They are both gentlemen and professional; Friendly, very knowledgeable about their craft and responsive to our concerns and needs. Very reasonable estimate, too. The installation was flawless and fast - Area was cleaned and debris removed as they progressed. Kitchen ceiling looks great and the lighting is perfect! Couldn't have asked for better service!!!
Response from Cornerstone Electrical Services, Inc.
"Bob, WOW! Thank you for these kind words. We will make sure Bill & Wade hear all the pleasantries you had to say about them and their service. We are so happy to hear of the incredible experience that you had with us. We are looking forward to working with you on your next project."

When we booked the job we told them a chandelier needed to be re-wired. When they arrived they said for the first time that they could not do so. They also needed to get a part to hang 2 chandeliers. When they discovered that they ran to a supply house to get it. They never checked the other so had to make a second trip. These two trips added $200 to the bill. Other than those issues the work was well done. I would use them again but be more involved in managing them.

The electricians were friendly and knowledgable and did their job very well. I would highly recommend them to anyone who needs electrical service. It must have been a dirty job for them, since they had to crawl under my mobile home to do wiring, but they did not complain and did a great job. Kudos to both Paul and Wade !
