Marvin Windows & Doors wouldn't replace leaking [air and dirt infiltration] patio doors. Said they were not designed for this area. Warroad Minnesota

To the owner of the Marvin door. You ask why the doors are sold in your area. Just like a car manufacturer makes sedans and 4-wheel drive vehicles, Marvin makes a variety of products to meet differenct environmental conditions.

On the ocean, mountain area or open field, where the home may get hit harder with wind and weather, the consumer needs to purchase the product that is rated to take the weather.

Some of the time, the right product for the environment will cost more and the decision is made on cost and not effectiveness of the product. Before purchasing your product, did you find out the DP rating of the door you bought?

Fenestration (windows and doors)manufacturers of quality products will have the DP rating information available upon request. Not all products are manufactured the same nor do they meet the requirements of every environment.

Did you have a fenestration professional help spec the door you purchased?

If this is a sliding door, you can add a sweep to the interlock that will help block air and water from infiltrating at that area.

If you have an Inswing Door - when the door is not in use, keep the Multi-point lock and/or head and foot bolts engaged so the door panels will stay in the correct position and wind will not push the panels inward allowing air and dirt to pass.

Make sure all weatherstip is in place and making contact.

If you did not purchase the correctly rated product, even when you change to PELLA, verify the WDMA rating of their door too so you do not end up with another concern and spend money for no reason.

Finally, if the weather hits that side of your home that hard, maybe you would be better served by putting a wall or stationary product in place.
