It is extremely important that you install our wood products within 30 days after receiving. We recommend that you install our windows and doors plumb, level and square, as the state of art. Prior to being installed, they must be kept into a heated and humidity controlled area. This is to prevent any damages that may occur if not stored properly. Wood is a living material and must be treated as such. Until you have closed the walls, you want to make sure that your windows and doors are well prepared for the tough life that they will have.
All surfaces must be painted or stained before installation. You should always take advantages of our unique paint shop. We can finish all our products piece by piece prior to assembly to give you the maximum protection and make you save time and money. You must also make sure that maintenance is done on a periodic schedule. The secret to keeping your wood products in pristine condition is to keep the finish on the wood surface in good condition and always follow the manufacturer’s recommendations.
The hardware should also be inspected periodically. Most of the hardware we supply can be easily cleaned with soap and water only. You should also lubricate the hardware with Petroleum Jelly or Lithium Grease.
It is also possible that you will see some condensation at the bottom of your new windows. Remember that they are far more energy efficient than the other used to be. To get rid of this modern phenomenon, you should look at reducing your humidity level inside the house.
