Mr. Bill Stevenson
Rain Gutters R Us
456 Somewhere Road
Best Town, Best State 88888

Dear Mr. Stevenson:

Your company recently installed rain gutters on my house in Country Meadows. We paid $4545 for new gutters on every face of our two-story home. The work took place on 10/2/2009. Attached is a copy of the invoice showing the work was completed and paid in full.

We were very happy with the service we received and your crew was very kind and professional. Unfortunately, during the heavy snow storm we had last week, our new rain gutters on the north side of our house fell off. While I am not an expert, it appears that several of the fasteners where inadvertently left out during installation.

We ask that you send your crews back out to complete the job that was paid for, replacing the gutters that have detached and inspecting the remainder of the gutters for similar issues.

We look forward to hearing back from you in the next several days to confirm when you will be returning. We expect to see your crew within the next three weeks and will wait until then before contacting the state contractor’s license board.

Feel free to contact me at (123) 456-7890 to schedule or visit or with any questions or concerns.
