We are Cortec.

Find out why we are more than just a building contractor.

We choose to specialise so that we can add real value to every project we undertake. For everyone involved.

We’ve developed construction expertise in the £750,000 to £3m+ range across Surrey and the surrounding areas, including Berkshire, Hampshire, West Sussex and South West London.

We focus solely on:


Residential projects

Our roots lie in high-quality works in high value homes. We work with you every step of the way and undertake large extensions, refurbishments and extensive remodelling through to new-builds.


Commercial & Community

We’re also well experienced in dealing with the extra pressures or commercial builds – like restricted access, adjacent tenants and partial occupation.

Why architects choose us

We are a family-owned principal contractor with a dedicated focus – we never fire off speculative tenders. We only consider projects that we have a proven track-record in, and that we know we can deliver better than anyone else.

Our attention to detail starts with our considered tender. We highlight where improvements or changes could be made and we scope out every detail.

When we tender for business we always mean business – and, of course, we always deliver.

“I have been impressed with their professional hands-on approach and effective project management together with their work ethic which encompasses honesty, integrity and reliability.”

Why homeowners choose us

Working to create a dream home is a true labour of love.

Our extensive experience in high-end residential new-builds, extensions and complete refurbishments means we can advise, project manage and deliver the perfect finish every time.

We work closely with the homeowner, the architect and other service providers to ensure budgets, deadlines and expectations are always met.

“The standard of the finish is exceptional and several friends and neighbours who have seen it have been very struck by the quality of the workmanship.  We could not be more pleased, thank you all so much.”

Why community clients choose us

It takes care, attention to detail and sensitivity to project manage building projects in a care home, a school, or any other community setting.

Our success in this field reveals just how well we understand these needs – as does our impressive 75% tender conversion rate.

Professional site management, excellent communication and collaboration are the ways we ensure that our work has little or no impact on the care home’s day to day operation.

“They proved to be utterly reliable, knowledgeable and courteous dealing quickly with any problems identified and working well with the Trust to minimise any disruption to the daily life of the residents.  All work carried out was to our total satisfaction.”

Why commercial clients choose us

Many commercial projects can be extremely lucrative investments. But they take a great deal of planning and require a principal contractor who fully understands the complexities.

And one who can deliver on time and on budget.

In the last 25 years we have created and refurbished many commercial spaces.  Whether it is converting disused office space to multiple apartments, carrying out a commercial new-build, or renovating an existing property – it’s very much a core part of what we do.

Landlords, developers and commercial organisations choose us for our dependable project management and focus on quality.

We developed 16 flats within former High Street office space with Cortec under a negotiated contract due to the success of previous projects. Our faith was not misplaced and another successful contract was completed on time and within budget much to the delight of the client.
