Anstow Limited Building Surveying Consultancy

Your Single Point of Contact for London Residential Portfolios

We believe that property management is personal. At Anstow, we don’t pass your instructions down to junior staff. When you hire us, you get the direct expertise of Andrew Watson BSc (Hons) MRICS—a surveyor with three decades of experience in the London and South East markets.

Expertise Rooted in Decades of Industry Leadership

Our founder, Andrew Watson, began his journey with a First Class Honours degree before training at Watts, one of the UK’s premier building surveying firms. After rising to Associate level and honing his craft in Buckinghamshire, he established Anstow to provide the kind of dedicated, niche service that larger firms often struggle to deliver.

Solving Complex Fabric Defects and "Unsolvable" Problems

We take particular pride in our track record with Building Pathology. We are often called in to resolve long-standing fabric issues where previous attempts by others have failed. Whether it’s a persistent leak in a mansion block or a complex roofing failure, we investigate thoroughly and provide clear, actionable remedial plans.

Comprehensive Project Services for Property Managers

We act as a trusted partner for resident freehold companies and portfolio investors. We manage projects from initial inspection through to practical completion, specialising in:

• External Repairs & Redecorations: Preserving the kerb appeal and integrity of your assets.
• Major Works: Including roof renewals and window replacements.
• Common Parts Refurbishment: Modernising interiors to maintain property value.
• Licences to Alter: Protecting the landlord’s interest when tenants propose significant changes.

A Flexible Approach That Fits Your Schedule

Property issues don't just happen between 9 and 5. We recognise that property managers and residents need a surveyor who is pro-active and available.

"We pride ourselves on being forward-thinking—identifying building fabric issues before they become costly emergencies."

Whether it’s an early morning site meeting, an evening consultation, or a Saturday morning inspection to keep a project on track, we adapt our working hours to suit the demands of your portfolio. We are committed to continuity; the person who takes your instruction is the person who delivers the work.
