Unless the repairs are critical to your health and safety, I'd suggest you take the plunge, but knowing Ghanaian landlords, consider it a personal loss. Besides lacking a property maintenance culture, he does not have your welfare at heart. Please understand that it is not personal. Everybody suffers the same dilemma in everything they do in Accra. Any recourse may be futile, stressful and perhaps a waste of extra cash. Be safe!
