ASH Chartered Building Surveyors

Since 1998, we have been providing clear, expert guidance to homeowners, businesses, and insurers across Surrey and South London. Founded by David Ashworth, our firm combines decades of technical knowledge with a practical, common-sense approach to property care.

Why Homeowners and Developers Trust Ash Surveyors

We know that property issues—whether it's a dispute with a neighbour or a mysterious crack in the wall—can be incredibly stressful. Our goal is to take that weight off your shoulders. We don't just identify problems; we provide the roadmap to fix them.

Specialists in the Party Wall Act

Navigating the Party Wall etc. Act 1996 is one of our core strengths. Whether you are a Building Owner planning an extension or an Adjoining Owner concerned about a neighbour's basement excavation, we act as your expert guides.

We handle everything from serving formal notices to preparing detailed Schedules of Condition and final Awards. Our experience allows us to settle matters amicably, ensuring your project stays on track while protecting your legal rights.

Getting to the Root of Building Defects

Is your property suffering from persistent damp, water ingress, or subsidence? We are "building detectives." We use advanced tools like camera mast surveys and ground investigations to find the source of the failure.

• Water Ingress & Dampness: We look beyond the surface to find the true cause, from condensation to structural failure.
• Subsidence & Cracking: Expert analysis to determine if movement is historic or active.
• Roofing Excellence: We have managed major re-covering projects for slate and flat roofs in Wimbledon and Hampstead, ensuring long-term protection for occupied blocks.

Professional Advice You Can Rely On

Beyond physical repairs, we provide high-level professional consultancy. This includes acting as an Expert Witness in disputes and handling Dilapidations for commercial clients. We have a proven track record of working with large property companies and insurers, bringing the same level of rigour to a corporate portfolio as we do to a single family home.

"Our mission is to provide practical and effective solutions to complex building problems, backed by over 25 years of Chartered expertise."

Whether you are a householder with a leaking roof or a developer managing a cleared site, we bring the technical authority and local knowledge required to protect your investment.
