Dorchester’s own “Renovation Husbands” – David and Stephen St. Russell – were the big winners in HGTV’s “Battle on the Mountain” on Monday. The final episode of the six-week home improvement series ended in triumph for the couple, who impressed judges and a national audience with their do-it-yourself design chops, beating out two rival couples and their celebrity advisors.

The St. Russells scored the finale’s $50,000 grand prize, on top of an additional $6,000 in prize money that they accumulated by winning competitions on earlier episodes.

The reality series, which was filmed last summer in the ski resort town of Breckenridge, Colorado, tracked three teams as they upgraded similar mountainside homes using a $100,000 budget. The husbands won for best kitchen, main bedroom suite— and for adding to the overall value to their property.

It’s the latest acclaim for David, 35, and Stephen, 33, who’ve built a huge following on social media for their DIY projects at their 1893 Victorian home in Dorchester.
