Very happy with the work
“The team at Sunstak provided exactly what I needed and nothing I didn’t. I requested a site visit for the quote, Sunstak arrived the next day and was able to schedule hot water heat pump installation for 8 days later. I am very happy with the work they carried out and the manner in which they did it. I’ll certainly be talking to them as needed in the future.”
