Connecticut homeowner guide

Main water shutoff

At the meter or at the wall entry. CT's large stock of pre-1960 homes has aging gate valves. Know your shutoff; freeze events require fast action.

Heating system type and fuel

Connecticut has a high proportion of oil-heat homes (the last significant oil-heat market in the US). Know your fuel type, tank location, and heating oil company. In winter, maintain the tank above 25%; delivery delays during storms can be 48-72 hours.

Basement condition

Most CT homes have basements. Inspect at move-in for cracks in the foundation walls, efflorescence (white mineral deposits = water intrusion), and sump pump condition. Connecticut has significant iron ochre issues in some towns (particularly in the Connecticut River valley), a reddish slime that clogs drain tile systems.

Gutter and drainage maintenance

CT's heavy tree cover and 45+ inch annual rainfall fill gutters fast. Clean twice yearly minimum. Clogged gutters cause ice dams in winter and foundation water intrusion year-round.

Heating oil monitoring

Track fuel oil usage daily during cold snaps. CT has experienced oil delivery disruptions during major storms. Keep 200+ gallons in reserve if your tank capacity allows.

Coastal and Long Island Sound prep

Connecticut's coastline faces nor'easters and occasional direct hurricane impact. Hurricane Sandy's surge affected coastal CT communities significantly. Know your evacuation zone, verify sump pump battery backup, stock 7-day supplies before June.

Roof inspection

Annual inspection before storm season. CT's older homes often have original wood sheathing under asphalt shingles; when sheathing is wet-rotted, roofing fails faster. Have a roofer assess the decking condition, not just the surface.

Heating oil fill

Fill the tank before prices spike in October-November. Schedule annual furnace or boiler service; boiler service in a CT old home with steam or hot water heat is essential for efficiency and safety.

Weatherization

CT's cold winters and older housing stock make weatherization high-value. Seal air leaks at electrical outlets, pipe penetrations, and attic access hatches. Add attic insulation if below R-49. CT Green Bank offers weatherization incentives.

Ice dam prevention

CT's frequent freeze-thaw cycles create ice dams on homes with inadequate attic insulation. Proper attic insulation and air sealing prevents ice dams; roof rakes address the symptom after the fact.

Emergency heat backup

CT's older homes with zone heating and oil delivery reliance need a backup heat source plan. A certified propane or kerosene space heater provides emergency heat. Know how to use it safely (ventilated space, not near combustibles).

Foundation wall crack monitoring

CT's freeze-thaw cycles and heavy rainfall cause foundation wall movement. Monitor horizontal cracks in concrete block foundations; horizontal cracks indicate soil pressure and are more serious than vertical cracks. Have a structural engineer evaluate any horizontal cracking.

Flood insurance for coastal CT

Long Island Sound communities and river valley homes need flood insurance. Standard homeowners insurance does not cover flooding.

Extended outage preparation

CT's tree canopy and aging grid infrastructure cause power outages lasting 3-10 days after major storms. Stock 7-10 days of supplies. Eversource: 1-800-286-2000. UI (United Illuminating): 1-800-722-5584. Have a backup heat source.

Long Island Sound exposure

CT's coast faces tropical systems that track up Long Island Sound; the Sound can funnel and amplify storm surge. Know your evacuation zone and have a plan for major storms.

Shut off and drain

Main water off at the meter or wall shutoff. Open all faucets. Photograph all damage. CT plumber wait times are 48-72 hours after major ice events or nor'easters.

Sump overflow and storm flooding response

Do not enter if electrical equipment is submerged. Call Eversource (1-800-286-2000) or UI (1-800-722-5584) to disconnect at the meter. Deploy backup submersible pump. Dry immediately; CT's summer humidity accelerates mold growth.

Connecticut's long outage history

CT has repeatedly experienced week-long outages after nor'easters (2011 Halloween storm, 2012 Sandy). Stock 7-10 days of supplies before each season. Eversource: 1-800-286-2000. UI: 1-800-722-5584. Generator outside only, 20 feet from windows. Oil heat requires electricity for the burner. Have a backup heat plan.

Evacuate and call from outside

Rotten egg smell: everyone out. Leave door open. Call 911. Eversource Gas: 1-800-989-0900. Southern Connecticut Gas: 1-800-659-8299. Connecticut Natural Gas: 1-800-659-8299. Do not re-enter until cleared.

Two exits, oil heat fire awareness, never re-enter

Know two ways out of every room including upper floors. CT's oil heat systems have specific fire risks: oil burner lockouts can create fuel accumulation. If you smell oil and the burner is clicking repeatedly without igniting, call your oil company, don't try to restart it manually. Designate meeting place outside. Crawl under smoke. Call 911. Never re-enter.
