We publish what we wish every Massachusetts homeowner knew before they signed: which Mass Save rebate caps just changed, which contractors lose 780 CMR code compliance, why your panel can't take the EV charger, when the ice dam is the symptom and not the problem.

Everything new from the Pro Build crew — sorted newest first. Mass Save rebate changes, code interpretations, real cost ranges, system specifications, and the "what your last contractor didn't tell you" deep-dives.

This is a contractor's blog, not a content farm. Every article goes through the same in-house standard before it's published — no exceptions, no AI shortcuts, no syndicated boilerplate.
Heat pump articles are reviewed by a Mass Save Heat Pump Contractor. Electrical articles are reviewed by a Master Electrician. No generalist staff writers.
Cost ranges come from invoices we've actually issued. Rebate amounts cite the live Mass Save table. Code references cite 780 CMR with section numbers, not paraphrased summaries.
When Mass Save changes a cap or 780 CMR adopts a new edition, we update the existing article and stamp the change date. We don't republish the same content under a new headline.
Each article has to add something the rest of the internet doesn't. If a topic has 50 generic guides, we either bring primary data, a cost breakdown, or a code citation — or we don't publish.
