Key Benefits Our Our Level Survey Service

Avoid costly claims

A claim on your subcontractor’s work can be financially damaging. Checking work such as the integrity of a flat roof job is important. Poor workmanship can lead to low or high spots that can lead to water pooling. Fixing such problems is costly and can be avoided with a professional level survey.

Useful data, drawings and information

It’s all well and good having a survey, but if the results you receive are difficult to understand and view then what is the use of it? We produce drawings with your requirements in mind. Your level survey data is produced in easy to read drawings. We can present data in formats such as heat maps, contour maps, coloured high or low points etc.

Accurate survey data

Gaining precise survey data for future design or construction work ensures your project goes smoothly. Problems with low or high spots on a concrete slab can be quickly spotted and accounted for early in the project. This will make things go smoother and reduce costs.

Great client relationships

We aim to make your life as easy as possible. Our 4.9 star Google & “great” Trustpilot reviews demonstrate the level of customer service we provide both before and after a project has finished.

Know that you are covered

As a professional surveying company, we carry all the relevant insurance to give our clients confidence in what we produce. We offer a money-back guarantee on all our work and have £5 million in both professional and public liability insurance.
