Montana House, South Croydon
How Independent Professional Advice Saved Leaseholders Over £100,000
A 60-apartment RMC development where Archery Estates challenged an unnecessary full felt replacement proposal — advising Directors to commission an independent surveyor, whose diagnosis revealed the root causes lay in defective flashings and verges. Targeted repairs resolved the issues at a fraction of the originally proposed cost.

The Results
What We Achieved
Why This Matters
"Many managing agents default to the contractor's recommendation without question.
Proper block management means challenging assumptions, commissioning independent advice and ensuring leaseholders' money is spent only where it genuinely needs to be.
Montana House demonstrates what independent, evidence-based management can save."
Client Testimonial
"Archery Estates provided clear, practical advice throughout a challenging period for the development. Their recommendation to obtain an independent survey ultimately saved leaseholders a significant amount of money whilst ensuring the roof issues were properly investigated and addressed. Communication improved considerably and the Directors felt supported throughout the process."
