Common Plumbing & Heating Issues in Plymouth Homes (And How Mckay Solves Them)
Plymouth’s mix of historic colonial homes and newer developments presents unique challenges:
❄️ Frozen Pipes in Winter
- Problem: Temperatures often fall below 20°F in January. Uninsulated pipes in crawl spaces or exterior walls freeze and burst.
- Mckay’s Fix: Install heat tape, add insulation, and perform winterization checks. They recommend setting thermostats no lower than 55°F when away in winter.
🚽 Low Water Pressure in Older Homes
- Problem: Many homes built before 1980 used galvanized steel pipes, which corrode over time.
- Solution: Mckay uses video pipe inspection to assess damage, then replaces sections with PEX or copper piping—improving flow by up to 40%, based on internal case studies.
🔥 Inefficient Heating Systems
- Issue: Boilers over 15 years old operate at <70% efficiency.
- Upgrade Path: Mckay installs high-efficiency modulating boilers (up to 95% AFUE) that cut heating bills by 20–30% annually, per U.S. Department of Energy data.
These tailored solutions reflect deep local expertise—something algorithms reward under modern SEO guidelines focused on user intent and helpful content.
