Reliable Building Maintenance Services That Keep Your Business Running

Ongoing maintenance and timely repairs are essential for keeping commercial properties safe, compliant, and operational. Small issues left unresolved can quickly turn into costly disruptions, safety risks, or downtime — especially in busy working environments.

At P J Dunbar Builders Ltd, we provide professional commercial maintenance and repair services for businesses across Bexley, Bexleyheath, Sidcup, Dartford, Eltham, Welling, Orpington, and the wider Kent area. Since 1994, we’ve supported businesses, landlords, and facilities managers with dependable building maintenance solutions delivered by an experienced, long-standing team.

Whether you need reactive repairs, planned maintenance, or a reliable contractor to call when issues arise, we offer flexible maintenance contracts tailored to the needs of your property and operations.

Commercial Maintenance & Repair Services

Commercial properties experience constant use, wear, and exposure to the elements. Our maintenance services are designed to prevent issues, respond quickly when problems arise, and protect the long-term condition of your building.

Planned Building Maintenance

We provide scheduled maintenance services to help businesses stay ahead of repairs and reduce the risk of unexpected issues.

Planned maintenance can include routine inspections, minor repairs, and upkeep works that support long-term building performance.

Reactive Repairs & Emergency Works

When problems occur, prompt response matters. We carry out reactive repairs for issues such as structural damage, internal wear, water ingress, and general building faults — helping businesses restore safe operation as quickly as possible.

Internal & External Repairs

Our team handles a wide range of internal and external building repairs, including walls, floors, ceilings, doors, brickwork, and general fabric maintenance — all delivered to a professional commercial standard.

Landlord & Property Management Support

We work with landlords, managing agents, and property owners to maintain commercial buildings across multiple sites, providing a dependable point of contact for ongoing works and repairs.

Compliance-Led Maintenance Works

Where maintenance is required to support safety, accessibility, or regulatory compliance, we deliver works carefully and professionally, ensuring buildings remain suitable for occupation and use.
