Thanks to Agnes's presence (and her skills as a housekeeper), the Wickfield household has up until this point been an idyllic place, even taking Mr. Wickfield's alcoholism into account. Uriah's presence in the house, however, entirely changes its character: instead of acting as a shelter from the pressures of the outside world, the Wickfield's home has now been invaded by one of those pressures. Uriah's presence in the household threatens to override even David's memories of the Wickfield home, which likewise serve as a source of comfort and strength; Uriah, for instance, now sleeps in David's bedroom, as if he has taken David's place in the household.
