Sarah Mitchell
Property Manager, Chelsea Portfolio (32 Properties) Service: Emergency Plumbing Response Date: December 2025
⭐⭐⭐⭐⭐ 5/5 Stars
“Exceptional Service While We Were Abroad”
“We own a Chelsea Harbour apartment but live in Dubai. Our property manager called at 3 am London time, reporting a major leak. Chelsea Property Renovation responded within 40 minutes, isolated the water, repaired the burst pipe, and documented everything with photographs and detailed invoices for our insurance claim. The entire situation was resolved before we even woke up in Dubai. Their international client experience showed comprehensive documentation, clear communication via WhatsApp, and they coordinated perfectly with our building management. The £380 emergency repair prevented what could have been £15,000+ in water damage. Professional, trustworthy, and exactly what international property owners need.”
Mr. & Mrs K.
Chelsea Harbour (International Investors) Emergency: Burst pipe in unoccupied apartment
⭐⭐⭐⭐⭐ 5/5 Stars
“Called Chelsea Property Renovation at 11 pm on a Friday when our boiler packed in, two young children, freezing January night, complete panic. Their emergency plumber arrived in 47 minutes. Diagnosed faulty pump, had replacement in van, heating restored within 90 minutes of our call. Fixed price £380 all-in, very reasonable for an emergency call-out at 11 pm. Polite, professional, cleaned up perfectly. Gas Safe certificate emailed the next morning. Can’t recommend highly enough. Saved our number for any future emergencies!”
