About us

Having worked for other people in the building trade for several years, Peter Janus founded Janus Construction in 2021 at the urging of his many delighted customers. Since then, he and his team have built an enviable reputation for quality workmanship and fair pricing. The fact that all of Janus Construction’s business comes through personal recommendation says it all.

Happy customers

Fully insured and accredited, Peter and his team take great pride in every job, small and large alike. This can be seen in the testimonials from our many happy customers.

Fair pricing

When quoting for a job, instead of plucking a figure from the air, Janus Construction takes a more evidence-based approach.
We work with a specialist firm of surveyors and estimators that uses purpose-built software to calculate a comprehensive cost for each project based on the square footage and volume shown on the plans. This results in a quote that’s both accurate and transparent, giving you the reassurance that you’re not being overcharged.
