Classic 1930s Metroland: bay-fronted semis, plus larger detached houses up the hill. We’re ten minutes from our base in Colindale, which means an emergency callout in Mill Hill is a short run for us.

What Mill Hill property tends to need
Ninety-year-old houses on their second or third heating system. Radiators get added over the decades without the pump or pipework being uprated, and the far end of the circuit stops heating.
Like the rest of the patch, Mill Hill sits in a hard water area, so limescale on cylinder coils and inside heat exchangers is a standing issue here too.

Everything else we do in Mill Hill
“Like an artist”
Constantine came in to look at a boiler which had been deemed beyond repair. Like an artist he quickly dismantled it and slowly started bringing it back to life. It was fascinating to watch. Without a doubt someone who has mastery of his craft. Would highly recommend.

Mill Hill questions
- How fast can you reach Mill Hill?
- Mill Hill is about ten minutes from our base, so it's one of the quickest areas on the patch for us to reach in an emergency.
- We've added radiators over the years and now the heating is poor.
- Classic 1930s semi problem. Radiators get added without the pump or pipework being uprated, so there isn't enough flow to serve them all. It's usually fixable without a new boiler.
