I live in Colorado where it is hot and dry in summer and very cold and dry in
winter. I hired a contractor to pour a concrete patio next to my house. He
poured the concrete all the way to touch the foundation without leaving any gap.
The patio is about 5-6 inches thick. The concrete touches the foundation and
part of the bottom board of the wood siding. Would that create a problem? If so,
what should I do to fix the problem?
IMHO it is a big 'yes' on both. I take it that there was no permit pulled
and/or no inspection done? As for fixing the problem, demanding that the
contractor remove the patio, repair any damage done, and refund the cost
would be a good start. Then hire someone who will do it right i.e. with a
properly excavated bed filled with solidly tamped stone base, with a filled
1/2" expansion gap, definitely not touching any wood let alone siding, and
well-sloped away from the house.
We live in Calgary AB up North similar climate.
We have side walk poured on two sides of house when
it was built in 1994 and back yard has big concrete pad
for RV parking. The side walks touch concrete walls
expansion joint is every 4 feet or so. So far no trouble,
house is stucco exterior, but the wood contacting concrete
may be a concern, if there is no roof on the patio, when it snows
it can make the wood wet when snow piles up on the patio.
I live up here in Alberta. Similar climate like where you are.
I have a 4 feet wide concrete path poured on one side(North) of house
tight againt basement concrete wall and foundation wall of attached
garage. Total length is ~60 feet and sloped away(3 deg. or so) from
walls very slightly so water can flow away. No problem for over 20
years. If I were you I wouldn't make the patio perfectly level.

Mine was poured touching the foundation and no problems at all, nor
do I see a problem. Touching wood though is a problem. The patio
should be below the wood with a gap of at least several inches.
You don't want water wicking up into siding, etc. Sounds like the
patio was poured at the wrong level and should have been lower.
