Please don't take this the wrong way Eagledance, but ask yourself, is it the house/space that is in need of some healing energies - or is it maybe yourself?
It sounds to me as though everything has kind of temporarily overwhelmed you. Moving home, even when it's what you wanted, is a fraught experience. Your life is turned topsy turvy for a while, and nothing is where you expected it to be. (I an STILL discovering "stuff" in boxes - and that's from over twelve YEARS ago!

)
You have a housewarming party - and presumably the folks there were all pals and ones who are happy for you? If not, then maybe there is a residual summat that needs to get shifted pronto. But if not, then as I suggested - you feel as if everyone wants some of you/your space, and this is hard to handle. It doesn't necessarily mean your home hads been in any way tainted though. (Sorry - only word I can think of.)
And the workmen? If it's a bought house, then obviously it's in your best interests to have damp dealt with! If it's a rental, then you just have to accept the landlord's decision to want to maintain his investment as he sees fit.
Sooooo......
You still feel somehow not quite settled. I reckon what you need is to dedicate your house protectors (wights/lares or whatever).
Set up a special place with a plant/flowers, candle, water, incense, and anything that speaks to you of your Path and the elements. Tend to it daily. Ask your God/desse/s to assist you in creating a home filled with love and laughter. Fill the space with music of YOUR choice, and fresh air. Take TIME - time to yourself and partner and those whom you worship or believe in.
All will be fine!
