Foundation work and waterproofing the basement. We discovered a crack in the basement in the Fall and got an engineer’s report and all the walls have cracks. It’s major work., and money. Work will begin in mid May when the ground has thawed. Not happy about it, but we have no choice. Our house is 50 years old and we bought it new. Over the years we’ve done many renovations and upgrades. We did a complete kitchen reno in 2000, but have since replaced all the appliances in the last couple of years. We also did a main bathroom reno two years ago. We’ve put in hardwood flooring in most of the house, all new windows and doors, new roof,etc. DH is currently taking down all the panelling and insulation in the basement in preparation. It’s never ending.
