It definitely did have a lot of value and customers, once they used it, loved it. From perhaps an emergency "this has stopped working" first call out you would have people then asking about exactly the sort of thing you mention with window blinds and become a repeat customer.
One thing we were looking to do was to offer it to companies as an employee perk - so the company would buy a certain amount of hours that could be used. Then staff could have a face to face call with the relevant tradesperson to discuss anything they like. It was too near the end though to get going :(
If you ever revive it, I worked for an insurance company that loves giving those kind of services as add-ons to their homeowners insurance (they're usually little-used and serve as great promotional copy).
Alas Homeserve, the massive insurance company who were the primary investors, took over all the IP and I think they just killed it. They bought CheckATrade [1] around the time we shutdown, so maybe it will see the light of day as part of that someday.
I have some exterior window blinds that need fixing, I'd love for someone to see it over a video call and get a quote before them coming.
That startup sounded great, I'm sad it failed :(
