Building Contractor in London

Our Building Services in London

House Extensions

A well-designed extension can create valuable extra space without the need to move. We undertake rear, side and wraparound extensions, carefully connecting the new structure to the existing property and working from approved plans where required.

Garage Conversions

An unused garage can often be transformed into a home office, bedroom, playroom or additional living area. We manage the practical building work, including preparation, insulation, internal alterations and finishing.

Brickwork & Repointing

Damaged bricks and worn mortar can affect both the appearance and weather resistance of a property. We carry out brick replacement, repointing, localised repairs and new masonry work, taking care to achieve a finish that suits the existing building.

Structural Alterations

We undertake structural changes such as creating new openings, removing internal walls and installing supporting steelwork. This type of work must be properly planned and completed in line with the relevant structural details.

Property Renovations

Our renovation work ranges from improving individual rooms to updating an entire property. We can help restore tired interiors, repair damaged areas and create a more practical layout for modern use.

Internal Refurbishments

Internal refurbishment services can include partition walls, plastering, flooring, carpentry, room alterations and general finishing work. We coordinate each stage carefully to keep the project organised.

Our Process

Our Building Service Process

We believe every successful roofing and building project starts with clear communication and careful planning. From your initial enquiry to the final inspection, our straightforward process ensures quality workmanship, complete transparency, and a hassle-free experience every step of the way.

Initial Discussion

We’ll talk through your plans, the current condition of the property and what you’d like the finished result to achieve.

Site Visit

A site visit allows us to assess measurements, access, existing construction and any practical issues that could affect the work.

Quotation and Planning

We provide a clear quotation based on the agreed scope. Where drawings, structural calculations or approvals are needed, these should be in place before the relevant work begins.

Construction

The work is completed in stages using appropriate materials and established building methods. We’ll keep you updated as the project progresses.

Finishing and Final Checks

Once construction is complete, we finish the agreed areas, inspect the work and clear the site.

Expertise

Building Services Experts You Can Trust

Planning building work can feel daunting, especially when access is limited, neighbouring properties sit close by or an older home needs careful handling. At RJC Roofing & Building, we provide professional building services across London, helping homeowners, landlords and property managers complete repairs, alterations and improvement projects with confidence.

Across London

Professional Building ServicesAcross London

We work with customers at different stages of a project. Some come to us with drawings, structural calculations and planning approval already in place. Others have an idea for improving their property but need practical guidance before deciding how to proceed.

Our first step is to understand the building, access and proposed work. London properties often present challenges that aren’t obvious on paper. Terraced streets in Camden or Islington may have no direct rear access, while older homes in Hackney, Ealing or Hammersmith can reveal previous alterations once work begins.

We plan around these details rather than treating every property in the same way. Materials, deliveries, waste removal and the order of work are considered before the project starts, helping to reduce unnecessary disruption.

Our building services are suitable for homeowners, landlords, letting agents, property managers and commercial clients. We can assist with planned improvements, repairs, structural work and wider renovation projects.

Why ChooseRJC Roofing & Building?

Good workmanship involves more than the visible finish. Foundations must be suitable, structural elements need to be installed correctly and each stage should be completed before the next begins.

We take a practical, methodical approach to our work. Before starting, we’ll explain the agreed scope and provide a clear quotation. During the project, we keep customers informed and discuss any unexpected issues that become visible once areas are opened up.

Reliability also matters. We aim to attend as agreed, keep the site organised and treat the property and surrounding areas with respect. On shared driveways, narrow residential streets and closely spaced London homes, careful site management makes a real difference.

Customers value honest advice, clear communication and knowing that the work won’t be rushed simply to reach the final finish.

Frequently Asked Questions

Have questions about our roofing or building services? We've answered some of the most common queries to help you better understand our services, our process, and what you can expect when working with RJC Roofing & Building. If you can't find the information you're looking for, our friendly team is always happy to help.

Do you take on small building jobs?

Yes. We undertake smaller repairs and alterations as well as extensions, renovations and larger building projects.

Can you help with both internal and external work?

Yes. Our services cover internal refurbishment, structural alterations, brickwork, groundworks, walls and wider property improvements.

Do I need planning permission?

That depends on the type, size and location of the project. Some work may fall under permitted development, while other projects require formal permission. This should be confirmed before construction starts.

Will structural alterations need calculations?

Often, yes. Removing load-bearing walls or installing steelwork normally requires calculations and specifications from a qualified structural engineer.

Can you work on older London properties?

Yes. We understand that period properties may require more careful investigation, sympathetic materials and adjustments to suit the existing construction.

How long will the building work take?

Timescales vary depending on the project, access, materials and any approvals required. We’ll provide a realistic indication after assessing the work.

Will you keep the property tidy?

We aim to maintain a safe, organised working area and manage waste throughout the project. The agreed areas are cleared when the work is complete.
