How well built are they?
Chartered buildings surveyor Ian Potts says, "In any range of buildings you will have the good and the bad examples, and, particularly, in any boom time you will get some that were, relatively speaking, thrown up.
"I understand that when some of the apparently most impressive Georgian terraces in the country have been refurbished, alarmingly poor construction has come to light.
"But I would not want to give the impression that all Georgian property is poorly built. Generally they're pretty sound, and the fact that they've lasted this long probably means they'll keep going a lot longer."
But, as a prospective buyer, there, says Ian, are a few things to look out for.
Georgian buildings will, typically, have parapet roofs. These can lead to two potentially expensive problems:
Firstly, the parapet will hide the roof, so, from ground level you can't assess what state it is in. You really need to put your head into the loft to look for signs of water coming in.
And secondly, the parapet will hide a lead gutter behind it. Problems occur when slates slip into it and block it, and the lead can also wear away.
This can lead to damp in the walls and rot in the timbers, including floor joists – which can be a big job to fix.
Next you should look down below. A lot of Georgian homes will have a cellar. But, for those that don't, make sure the sub-floor vents are clear, because without a good airflow the floor can rot.
Fortunately, in terms of insulation, a Georgian home can have a built-in advantage over other period homes.
"Generally they have very substantial external walls made of stone," says Ian. "They can take long time to heat up but once they're warm they're pretty good.
"If they're not stone they will typically be brick covered with render. Some will have a cavity (which can be filled), and some won't, but it's very difficult to tell with the render on."
