Partnerships

Partnerships — the network behind the numbers

Estimator is the project-numbers seat of a small network of free online tools built and run by the same team. One flagship site represents each platform below. When a job is not measuring, counting or costing, these are the tools we trust with it.

Partner with us

We partner with people and businesses whose audiences measure, build and improve things — contractors, trades, DIYers and the suppliers who serve them:

  • Tool and utility websites — if you run a free online tool our readers would find useful, and our estimators would help yours, we are interested in listing each other and cross-promoting.
  • Creators — bloggers, YouTubers and newsletter writers covering construction, remodeling and DIY: our estimators are free to link to and free to embed on your own pages.
  • Businesses — if your customers quote jobs, order materials or plan projects, we are open to integrations and joint efforts that genuinely help them.

What we offer

  • Listings — a place in our network and resource pages where there is a real fit for our users.
  • Cross-promotion — featuring each other’s tools and content where our audiences overlap.
  • Integrations — every calculator on this site can be embedded on your website free, with no attribution required, and we are open to deeper integrations.

We keep partnerships simple and honest: no paid placements dressed up as recommendations, and we only list things we believe are genuinely useful to our users. If that sounds like a fit, email us:
