Structural Work in Bexley & Kent

Safe, Professional Structural Alterations for Homes Across Bexley, Bexleyheath & Kent

Structural work requires precision, experience, and absolute trust. Whether you’re removing a load-bearing wall, creating an open-plan living space, installing steel beams, strengthening an existing structure, or carrying out remedial work recommended by a structural engineer, the safety and integrity of your home depend on choosing a qualified and experienced builder.

P J Dunbar Builders Ltd has been carrying out safe, high-quality structural work across Bexley, Bexleyheath, Dartford, Sidcup, Eltham, Welling, Orpington, and wider Kent since 1994. For over 30 years, we’ve worked closely with structural engineers, architects, and local authorities to deliver structural alterations that meet strict building regulations and provide long-lasting stability and performance.

No matter the size of your project — from removing a single load-bearing wall to major structural changes as part of a renovation, extension, or conversion — our experienced, long-standing team ensures every stage is carried out safely, correctly, and to the highest professional standard.

Types of Structural Work We Carry Out

Every structural project requires careful planning, engineering oversight, and experienced hands. Below are some of the most common types of structural work we complete across Bexley and Kent.

Removing Load-Bearing Walls

Homeowners often want to open up their ground floor by removing internal structural walls.

We work with structural engineers to install RSJs (steel beams), padstones, and supports that maintain the integrity of your home.

This is a common first step when creating open-plan kitchen-diners or improving the flow of older properties.

Installing RSJs, Steel Beams & Structural Supports

We handle the supply and installation of steel beams, universal beams (UBs), universal columns (UCs), flitch beams, and lintels, depending on your project needs.

All steelwork is installed in line with engineer specifications and signed off by building control.

Creating New Structural Openings

Whether you want a wider opening between rooms, bi-folding doors at the rear of your home, or a new doorway, we safely create structural openings while ensuring your property remains fully supported at every stage.

Chimney Breast Removal

If you want to reclaim space from a redundant chimney breast, we can safely remove it and install appropriate structural supports.

This work must be completed by an experienced builder and approved by building control.

Structural Repairs & Reinforcement

Subsidence cracks, sagging floors, failed lintels, ageing brickwork, or structural movement can all require specialist repairs.

We work closely with engineers to carry out reinforcement work, underpinning, strengthening, and remedial repairs to stabilise and protect your home.

Floor & Roof Structure Alterations

We complete structural work as part of loft conversions, kitchen extensions, and renovations, including installing new joists, strengthening existing ones, and modifying roof structures.

Foundation & Groundwork Improvements

For extensions and larger structural changes, we carry out groundworks, excavation, foundation strengthening, concrete pads, and other structural preparations required for safe, compliant building work.

Benefits of Professional Structural Work

Below are the key reasons homeowners across Bexley and Kent invest in structural alterations carried out by an experienced, reputable builder.

Create Modern, Open-Plan Living Spaces

One of the most popular reasons homeowners request structural alterations is to remove internal walls and create brighter, open-plan layouts.

Whether you're combining your kitchen and dining room or opening up a dark ground floor, structural work can completely reshape how your home feels and functions.

Improve Layout, Flow & Usability

Older homes often have cramped rooms, narrow doorways, or awkward layouts that no longer suit modern living.

Structural changes allow you to reconfigure spaces so your home works better for your lifestyle — whether that means wider openings, new access points, or reimagined room layouts.

Increase Property Value & Appeal

Homes with open-plan layouts, modern structures, improved support, and upgraded internal frameworks are highly attractive to future buyers.

Structural improvements can dramatically increase long-term value, especially when they form part of larger renovation or extension projects.

Ensure Safety, Stability & Building Regulation Compliance

Cutting corners on structural work is dangerous. With our decades of experience, collaboration with structural engineers, and knowledge of building regulations, we ensure every alteration is safe, compliant, and built to last.

You gain confidence knowing your home’s structure remains sound and secure.

Our process

Our Structural Work Process

Structural work must be carried out carefully, correctly, and with full regulatory oversight.

Here’s how we ensure your project runs smoothly from start to finish. 

Consultation & Expert Guidance

We start with a discussion about your structural goals — whether that’s removing walls, improving flow, widening openings, or addressing structural concerns.

We’ll help you understand what’s possible and outline the steps required to complete the work safely.

Site Survey & Assessment

Next, we perform a detailed assessment of the area involved. We identify load-bearing walls, existing supports, access requirements, and any potential risks.

This step allows us to provide accurate advice before involving a structural engineer.

Structural Engineer Calculations & Drawings

Structural alterations must be backed by an engineer's design. We can work directly with your chosen engineer or recommend one of our trusted partners.

They will specify steel sizes, load requirements, padstones, and supports, along with the method statement for safe installation.

Building Control Approval

We handle building control submissions on your behalf, ensuring the work is inspected and approved throughout the process.

This protects your home now and any future sale or mortgage process.

Pre-Construction Planning

Before work begins, we review timelines, safety measures, temporary supports, access points, waste removal, and structural installation procedures.

Clear planning ensures a safe, efficient build with minimal disruption.

Structural Installation & Removal

This is where our experience truly matters. We install temporary supports (such as Acrow props and strongboys), fit RSJs or structural steel, and ensure the load is safely transferred.

Once complete, the old structure can be removed and the new opening formed. At each stage, we follow engineer specifications and building regulation requirements.

Finishing, Plastering & Making Good

After structural work is complete, we ensure the area is neatly finished — with plastering, skirting, adjustments to electrics, and preparation for decoration.

This ensures the alteration blends seamlessly with your existing home.

Structural Work FAQs

How do I know if a wall is load-bearing?

We can usually identify whether a wall is structural during a survey based on its position, thickness, joist direction, and the structure of your home.

In some cases, confirmation from a structural engineer may be required.

We will guide you through this process to ensure accuracy and safety.

Do I need building control approval?

Yes. Structural work must be approved by your local building control department.

We handle the submission, coordinate inspections, and ensure full compliance so you receive proper documentation for future property sales or mortgage applications.

Will I need to move out during structural work?

In most cases, no. Homeowners can remain living in the property as long as the workspace is safely isolated.

We minimise disruption, keep the area tidy, and ensure safety throughout the build.

Can structural work be part of a renovation or extension?

Absolutely. Many of our structural projects form part of larger home improvements, such as kitchen extensions, loft conversions, or open-plan reconfigurations.

We coordinate all elements to ensure a seamless result.

Will removing a wall affect resale value?

Open-plan layouts are extremely desirable and often increase the value of a home.

Structural improvements that create modern, spacious layouts are typically very well received by buyers.

Do I need a structural engineer for this work?

Yes — any structural alteration requires calculations and drawings from a qualified structural engineer.

We work closely with trusted engineers or can collaborate with your chosen professional.

Their design ensures the structural change is safe and compliant.

How much does structural work cost?

Costs vary depending on the scale of the alteration, the size of the opening, the steel required, access complexity, and finishing work.

Once we’ve carried out a survey and received engineer drawings, we provide a clear, itemised quote.

How long does structural work take?

Simple load-bearing wall removals can take a few days, while larger openings or multi-room structural changes may take longer.

Once plans and calculations are complete, we provide a detailed schedule so you know exactly what to expect.

Is structural work safe?

Yes — when carried out professionally. We follow engineer designs, use correct temporary supports, liaise with building control, and work with an experienced team to ensure the safety and integrity of your home at every stage.
