Additional Notes

Complaint: I have an open contract with CT Basement systems to complete a project that started on Nov 3rd. I was told both before and after I signed the contract that the implementation would take 2-weeks and be professionally managed with a Project Manager assigned. The implementation has been disorganized and remains unfinished.

Desired Settlement: My desired outcome is a review of the open items on site, a quality inspection, and an organized plan to finish the job, with appropriate resources assigned.

Business Response: We finished the project and walked through the new finished basement with the homeowner, who signed off that everything was complete.  The next day he called and said that there were a few minor items missed, and we said no problem, and made arrangements to come back, which we did.  I a bit confused because yesterday we were there at the house taking care of a few small items - and today the customer made this complaint.  Yesterday he reported a cable wire needed a tweak by our electrician and there was a small vibration in pipes.  So yesterday we made arrangements for our plumber and our electrician to go take care of these things.  Our project manager has been responsive, yet today we get this complaint.  Today I left a message with the customer, on Christmas eve, the same day this complaint was filed.  We are always responsive and have never walked away from any customers concerns in 33 years.  We will take care of these few items which are very small and admittedly not urgent, very soon.  We are happy to be able to finish yet another basement project so well.

Consumer Response:
Complaint: ********

I am rejecting this response because:

I do not agree with the characterization regarding the status of my basement project or purported project managenent services received.  The additional arrangements made have not been communicated to me.  The project began 11/2 and remains incomplete with open items and quality issues.  The Project Manager has never been on site since the project began.

We are willing to work with CT basement systems to see if the project can be organized and managed to completion.

Consumer Response:

I was writing to notify you that the complaint with CT Basement Systems has been successfully resolved.  They met with me and then implemented a plan that resolved all the outstanding issues.


I wanted to ensure that the complaint online was modified accordingly as successfully resolved by the business.


Thanks and let me know if there is further action required on my part.
