Repair

Cracks can always be repaired and regardless of the preparation done some may reappear. However your best chance at successfully repairing those cracks is to dig out the crack, fill it, tape it with a fiberglass mesh tape and sand it smooth. Then prime over your patched area before repainting.
Our painters are all experienced in drywall repair and replacement. Virtually any repairs that need to be made can be done as part of the preparation work we do prior to painting.
We always recommend waiting two weeks before allowing any cleaning agents to come in contact with the new paint. Paint dries in a matter of a few hours but all paint goes through a curing process which takes longer.
Many painters will replace rotted wood during the course of a paint job, as will our crews. However, if the extent of the damage is more than we normally handle, we will inform you of that and you can make a decision as to whether you want a carpenter you already know of to make the repairs or you would like us to recommend one to you. If rotted would is discovered during the course of your painting we will notify you of that so that you can determine what course of action you would like to take.
There are a number of reasons. Go to our exterior paint problem solver guide for an explanation of a few different types of paint failure.
Mildew is something that practically every house develops and it must be dealt with a proper understanding of what it is, why it's there and how to get rid of it. Read about mildew in our library.
Cupping is a form of warping and is caused by uneven shrinking or swelling within the individual boards. Shrinking and swelling is normal in wood, through temperature changes, but can be increased if moisture is allowed to enter the wood unchecked and spacing is not maintained between boards to encourage airflow. When wood is left unprotected it can have a tendency to absorb moisture which can cause it to cup or warp.

Most standard lumber grades have a high proportion of flat grain (horizontal), while premium lumber, including siding will be edge grained (vertical). Edge grain lumber has better "paintability". If the decking was not coated on all six sides, which would greatly help to stabilize the dimension of the lumber through reduced moisture intrusion, the moisture content of the lumber may fluctuate between 12% and 20+%. Also, when pressure-treated lumber is improperly positioned with the crown of the growth rings of the wood facing down versus the proper installation with the crown of the growth rings facing up (i.e., with the ring orientation viewed from one end of the lumber, you should see the half circle wood rings with the round side on top). Improperly positioned decking lumber will have a greater tendency for moisture absorption and hence a greater opportunity for warping.
