Wood stairs squeak after new handrail & baluster installation
We hired a contractor to remove our 50 year old wrought iron handrail and balusters and install new hardwood ones. The job was completed yesterday and today I noticed that some of the stairs have developed a squeak where none had existed before. What could be causing this and what can we do about it? I plan to call the contractor on Monday, but in the meantime, any thoughts are appreciated, thanks.
