So, back to the issue of the wording, which is what you posted for:
Focus on the things that might truly affect them.
Hours, parking, damage to the lawn (which isn't their lawn but they'll see it), security.
Here's a stab at it:
For the next two weeks (Feb.29-Feb37) we'll be having renovations done to our basement during the day (between 8am and 4pm). They'll be putting up drywall, so there will be some banging, and doing new electrical circuits (some slithering).
We've briefed them on where they can park (they'll have our spaces available to them, and I've given them our parking passes) and other matters. They've assured us their supplies will be stacked inside so as not to damage the lawn.
When we checked their references, we asked about how considerate they were, and they got good marks for this, so we are hopeful this won't impact you much.
We will not be home during this time--you can reach us at 000-000-0000. Our contractor's name is Bill Slothifricasse & Daughters, and their business number is 000-000-0000
Please let us know if you experience any problems during this construction.
