Mass & Co

Over Three Decades of Essex Property Expertise

Since 1990, we have been the go-to independent firm for property advice in Essex, London, and the Home Counties. Founded by John Mass and now led by Christopher Stewart—who has been a cornerstone of the business since 1992—our team brings over 30 years of deep-rooted local knowledge to every instruction.

We understand that property is about people. Whether it’s the premises your business occupies, your home, or a commercial investment, our mission is simple: to help you maximise your assets and minimise your costs through clear, professional guidance.

From 16th-Century Gems to Modern Commercial Hubs

Our experience is as diverse as the properties we handle. We are just as comfortable surveying a Grade II listed 16th-century building in Brentwood High Street as we are negotiating a lease for a modern industrial unit or a trendy leisure venue.

"Our property advisors each have over 30 years of experience in the local market, ensuring you receive advice backed by decades of real-world data and local insight."

Strategic Advice for Landlords, Tenants, and Investors

We act for a broad spectrum of clients, from national occupiers and property companies to local individuals and professional partners like solicitors and architects.

• Commercial Agency: We handle the disposal and acquisition of retail, office, industrial, and leisure properties, with a strong presence in Brentwood, Billericay, and Upminster.
• Lease & Rent Negotiations: We specialise in rent reviews and lease renewals, advising on re-structuring leases to obtain the best results in challenging markets.
• Professional Valuations: We provide expert valuations for Court, taxation, and asset review purposes.
• Residential Support: Beyond commercial, we offer comprehensive surveys for residential purchasers and specialist advice on lease extensions for flats.

Protecting Your Interests: Party Wall & Business Rates

If you’re undertaking building work or are affected by a neighbour's project, we provide expert guidance under the Party Wall etc. Act. We act as either Building Owner or Adjoining Owner surveyors to protect your property and produce the necessary Award documents.

Furthermore, our work with rating consultants has saved local businesses significant sums on their Non-Domestic Business Rates. We also produce Schedules of Condition for incoming lessees of commercial buildings, a vital step in limiting your liabilities when a lease eventually comes to an end.
