Several years ago we had a "Mannington Laminate Floor" installed in several rooms of our house. The flooring was the "Click" style. Since then we have had numerous problems due to bad installation techniques and one problem due to imprroper use on our part. The dealer and installer have since gone out of business... We are on our own... The first attached picture shows a small area directly in front of our computer station (circled in red) that the wheels on the chair have dulled the surface.(our fault). The the Blue line in the first and second pictures show where the installer (?) seamed 2 rows of flooring with the end seams even with each other... Here is the question... I have access to several boxes of the same flooring material.. How difficult would it be for me (above average technical ability) to replace the small area directly in front of the computer station AND the 2 rows of parallel seamed boards back to the wall and stagger them??? If possible, where do I start and how much existing material must be removed / replaced to do the job? Maybe it is best left to a professional but.. just wanted to see if I can do it!
