Why CJX Construction

Why Clients Choose Us

Fixed, itemised pricing. A programme you can hold us to. And a finish we are happy to photograph and put our name to.

The Difference

Most Building Projects Fail On The Same Three Things

Price that moves. A programme that slips. And a finish nobody would accept in their own home.

We built CJX around removing those three risks. Every project is priced line by line before a spade goes in the ground, run to a programme agreed in writing, and finished by trades who have worked together for years.

It is not a complicated promise. It is just an unusually well-kept one - which is why most of our work now comes from clients we have built for before, and the architects and surveyors who recommend us.

Why CJX Construction?

Six Reasons Clients Come Back

Clients return to us because the work is right, the programme holds, and they always know where their project stands.

Exceptional Craftsmanship

Time-served trades and a finish that holds up to close inspection, long after handover.

Transparent Communication

Itemised pricing, weekly progress updates and a single point of contact throughout.

Experienced Professionals

Site managers, joiners and specialists who have worked together on projects for years.

Attention To Detail

The junctions, tolerances and finishes that separate a good build from an excellent one.

Reliable Project Delivery

A realistic programme agreed up front, and the site management to keep it on track.

Quality Materials

Specified for durability and performance, sourced from suppliers we have used for years.

What You Get

Commitments We Put In Writing

Not aspirations. These are terms in our contract and checks in our process.

Fixed, itemised pricing

Broken down by trade and phase, with no provisional sums hiding the difficult questions. Variations are priced and agreed in writing before the work happens.

A programme you can hold us to

An agreed completion date in the contract. Where a delay is our responsibility, we absorb the cost of it.

One name and one number

A dedicated site manager who answers the phone, plus a written progress report with photographs every week.

Fully insured and accredited

£10m public liability, £10m employers' liability and professional indemnity cover. CHAS accredited, with current CSCS cards across the site team.

Clean, respectful sites

Dust-sealed separations, agreed working hours, and a site your neighbours will not complain about. Most of our clients stay in the property throughout.

Warranties that outlast us

A minimum twelve-month defects liability period on everything, and a ten-year structural warranty on new dwellings.

Our Process

How A CJX Project Runs

A clear, five-stage route from first conversation to the day you get your keys back.

Consultation

We visit the site, understand your requirements, ideas, budget and expectations.

Planning

We prepare the construction strategy, programme, design requirements and detailed costings.

Construction

Our trades bring the project to life using quality materials and proven workmanship.

Quality Inspection

Every stage is signed off against our own checks and the relevant building regulations.

Handover

The finished project is cleaned, snagged and handed over with warranties and certificates.

In Their Words

Don’t Take Our Word For It

The measure of a construction company is what its clients say once the scaffolding comes down.

We interviewed four builders and CJX were the only ones who talked us through what could go wrong rather than just telling us what we wanted to hear. Eleven months later the house was finished, the final account was within a whisker of the original quote, and we knew exactly where things stood every single week.

Eleanor Whitfield

New Build · Richmond, Surrey

Refurbishing four floors while two floors carried on trading was always going to be the difficult part. We did not receive a single escalated tenant complaint in seven months. That is not luck - that is planning and site discipline.

Marcus Ashford

Commercial Refurbishment · Holborn, London

We had two children under five and stayed in the house the whole way through. The team was clean, quiet where they could be, and honest when they could not. Our kitchen was out of action for exactly the four weeks they said it would be.

Priya Raghunathan

House Extension · Highgate, London

A Grade II listed house with damp, failed lintels and a conservation officer to satisfy. CJX handled the whole thing, including the parts of it that were genuinely unpleasant, and the finished house looks like it was always meant to be that way.

James Okonkwo

Listed Building Restoration · Islington, London

Working in a managed block with a two-hour daily lift slot would defeat most contractors. They planned around it rather than complaining about it. We have already instructed them on our second property.

Sophie Lindqvist

Interior Refurbishment · Belgravia, London

As a small developer, cost certainty is everything. CJX gave me a fixed price that held, delivered both units to EPC A, and got them reserved off-plan. I have three more sites and they are pricing all of them.
