I was about to suggest you were crazy but after looking at the photos
you may have some issues.

However I suggest a couple of thoughts. It would appear the carpet
people would have had to work extra hard to put the carpet in as it appears.
Why would they do that?

You say you measure "the length and with to conform it is in perfect
rectangular shape" That only confirms it is a parallelogram. To versify it
is square you need to measure both diagonals and assure they are exactly
equal. You also may face the problem that the walls may not be perfectly
straight. It is a very unusual home that has everything perfect.

Carpet is a stretchable product. It may have been stretched unevenly
before or during installation.

We just moved into a new house in end of November with berber carpet
in the family room, stairs and master bedroom. The carpet in the
family does not seem to align properly. We measured the width of the
room to confirm it is in perfect rectangular shape. Unfortunately
the carpet installer disagree with us, they said the tufting lines
are bowed in one area. I took pictures at all four sides of the
carpet and I think the entire carpet is tilted (see below links).
The response from the builder can be found at the end of the message.
Can someone tell me if the carpet installer is correct?

In additional, we noticed some unexplained damage spots in our carpet
(see below links). At first the damaged spots were found in the
stairs to the master bedroom and basement and the carpet installer
fixed the one found in the stair to master bedroom a few weeks ago,
but more new damaged spots are found recently and I noticed at least
one in the masterbedroom and two in the family room, the basement
stairs now looks extremely bad. The damage spots have harden surface
and it feel like it is burnt by some glue or chemical but we never
spill anything on the carpet and we use vacuum the carpet once per
week. Can someone explain what can cause these? Is the carpet
defective? http://www.pbase.com/wpg_ventura/ima...94769/original

Response from the builder
-------------------------
This letter is in response to your recent e-mails regarding your
berber carpet. Your claim is that the carpet is not aligned properly.

I have inquired with RRRRR Floor Store on your behalf and asked them
to send a technician to your home to investigate this claim. BBBB
BBBBBB (the owner of Regency) inspected your carpet and confirmed
that the installation is correct. BBBB explained that the pattern in
the carpet is such that 2 "lines" should run at 45 degree angles to
the wall.
He inspected the carpet and confirmed that this is the case at your
home.

The issue you are concerned with is the tufting lines. BBBB stated
that the tufting lines are bowed in one area of your carpet and never
run perfectly straight in any carpet due to the nature of the
manufacturing method. Tufting lines are often bowed; however, lining
up the pattern in the carpet with the walls correctly is the goal of
the carpet installer. The picture you sent, as well as Regency's
written report both indicate that the pattern lines up correctly.

Therefore, there is no further action required on this issue. If you
have any further questions regarding warranty standards, please do not
hesitate to contact us.
